Building Healthy Soils with not so primitive Biological Mechanical Components

File Under: Bad Religious Dogma - or would that be Fogma ?
What if Agriculture after World War II had the same blank Cheque funding for it's own 'Manhattan Project', instead of going down the Green Revolution path brought to us by today's Toxic Know-It-Alls ?

See this guy over here on the right ? He is Agricultural Ecologist, Dr Jerry Glover who with the help of photographer Jim Richardson of the National Geographic Society and Sculptor Steve Tobin known for his nature exhibits put together a beautiful underground visual of what root systems  in healthy pristine prairie soils actually look like. In so doing, they revealed an unknown hidden world and understanding of a complex root infrastructure that the average person above ground couldn't possibly otherwise visualize or imagine. But for the moment, I'd like to explain why most soils don't actually look like this in nature anymore. Mostly, the reason soils today are in poor condition has to do with the so-called scientific modern day enlightenment which has since 1914 -WWI (but especially since 1950), tried indoctrinate all of us into accepting how & why nature is so horribly flawed, badly designed, terribly inefficient and that only their technological innovations of this world's elites will save us from it's primitive foundations. But are the microbiological things of our natural world really all that primitive ? Interestingly other responsible scientific research is beginning to find out that this type of flawed worldview is itself untrue and in many cases caused irreparable damage in some areas. At the end of this post I'll talk a little more on the above exhibit. But here is a short introductory clip:
"Plant roots are vital components of the earth's ecosystem. They are necessary for all plant growth, including the production of food and nutrients for humans and many other organisms. However, as root systems are out off sight, their beauty and importance often go unnoticed. Exposed: The Secret Life of Roots showcases the presence and importance of roots through visually stunning root representations using the work of agricultural ecologist Dr. Jerry Glover, sculptor Steve Tobin, and photographer Jim Richardson."

So where did Humans go wrong when it comes to Soils & Land Management ?
Image typical of deep soil chiseling of Imperial Valley fields


(Imperial Valley Subsoil Chiseling)
For 20+ years I traveled from my mile high home in the San Jacinto Mountains above Palm Springs California all the way to Imperial Valley at least once a week, sometimes twice. Often while driving to work in early mornings in summer when I'd pass a field like the one above and world see the farmland subsoil deeply cut into and chiseled as the one above in the photograph. I'd also see parked next to the plowed field the very farm implement or deep plow apparatus responsible for the large gouges in the Earth sitting idle like the one at right here. The landscape down there is an ancient sea bed where the soils are a very fine almost clay-like in structure. Periodically if such deep tillage isn't undertaken, this ground remains hard packed like adobe. The water percolation is almost nil in worst case scenarios when they attempt to flood irrigate. Such deep tillage and later light tilling with smaller plows afterwards are necessary for the soils to restore back to that fluffiness of structure for not only better water percolation, but also crop plant root development. This Southern California valley is a major industrial farming area where a single corporate farm entity may may own land in the 1000s of acres. There is no life to these soils in the healthy microbiological sense. Such industrial farming strategies and practices are what destroy the soil microbial community. Advertisements from Tillage implement companies extol the wonders of their soil ripping products to their potential farmer customers by illustrating how they can prevent stagnant water build up from heavy storms or common flood irrigation practices which no longer percolate into impervious soils. But there is far more that keeps the soils lifeless other than constant regular tillage, that would be the overuse and abuse of synthetic chemicals.

For decades the soils of this ancient lake bed of Imperial Valley on both sides of the border between the USA and Mexico have been drenched in synthetic fertilizers of all kinds. Herbicides, fungicides and insecticides applied either from the ground or the air also contribute to this damage. Taken altogether, these too kill the healthy soil biology as does excessive uses of plowing and other deep subsoil tillage. This is why these desert valley soils are mostly sterile and strictly mineral based in their structural make up and colour. Pick up a handful of Imperial Valley soil and you will not find any of the rich black soil common with most natural systems. Chemicals, like excessive plowing also help to favour noxious weeds by eliminating the very checks and balances nature has used for 1000s of years to keep weeds under control. Interestingly, all these industrial farm mismanagement practices are identical to other irresponsible land mismanagement practices used by the US Forest Service and Timber Industries. Take the photo  example below of this ridgeline in the Trabuco Ranger District of Cleveland National forest in the Santa Ana Mountains of Southern California which has been stripped of it's mycorrhizal hosts (chaparral) and completely replaced by weeds which thrive in a bacterial system of soil creation. Destroy above ground mycorrhizal hosts and you destroy the underground mycorrhizal grid and allow a bacterial system to replace it which favours weeds, particularly those weeds we call Ruderals.

Somewhere back in the 1960s-70s, it was ignorantly assumed that stripping most all major ridgelines of their chaparral was a great idea for a major firebreak to control any future wildfire event. However, this replacing of the chaparral plant community (which is host to mycorrhizal fungi) by these regular control burns, vegetative mastication, synthetic chemicals, and/or bulldozing actually allowed a bacterial underground system to be created which favoured invasive grasses and other noxious weeds like cheatgrass, mustards, radishes, star thistle, etc. This turned out to be a huge backfiring mistake. Oddly enough those ignorant irresponsible practices are the exact mirror image of industrial farming methods which create far more problems than they were originally meant to solve. The result for the forestry was not stopping wildfire, but rather the creation of a mismanaged landscape scenario which actually fed worse wildfire condition scenarios than preventing them. If the idea was to slow down wildfires, the true reality resulted in speeding up their spread. From that point the domino effect gets worse. Take for example the usage of slurry type phosphate based fire retardants used in stopping fires. Would you believe this actually spreads Cheatgrass and other runderals ? Take a look below.

Photo by Jed Little
A year after the Fourth of July fire on Mount Jumbo, a long green line of cheatgrass is visible where fire retardant was dropped. The red slurry retardant allows some exotic weeds to replace native grasslands, according to preliminary results of a study by Salish Kootenai College and the University of Montana. Now read this portion I've quoted below from the online journal, The Missoulian:
"The study raises the possibility that the red slurry, while helping to slow a wildfire's advance, could ultimately worsen grassland fires by promoting the growth of cheatgrass, one of the most flammable invasive weeds in the West."
"According to preliminary results, the retardant's fertilizerlike nutrients significantly increased cheatgrass and tumbleweed mustard, both exotic annual species, at the expense of native perennial grasses on the mountainside."
"The invaders benefit from the jolt of nitrogen and phosphorous in the slurry, which native and exotic perennials largely ignore because they are accustomed to nutrient-poor soils. Cheatgrass and tumbleweed mustard didn't spread where the fire burned alone, but they exploded in areas that were burned and hit with retardant, the study found. The two invaders have spread from 51 percent to 88 percent on Mount Jumbo since the retardant was dropped, although two perennial invaders, spotted knapweed and Dalmation toadflax, decreased."
(Source - Missoulian)
I literally hate going for a hike and receiving the nasty end of an assault of stickers from walking through a mismanaged field infected by a  Cheatgrass (Bromus tectorum) invasion. These stickers in boots and socks are so incredibly annoying that you need to stop periodically to take the boots off and clean both boots and socks to regain your sanity. They can also be dangerous to your pets and other domestic animals. If that is true, then it is also true that their overwhelming presence is not good for wildlife either. Now there were a couple of interesting things referenced in that article by the Missoulian. Notice that these annual plants [ruderals = Cheatgrass, Mustards, Radishes, Tumbleweeds, etc] thrive in a nutrient enriched soil from the presence of excessive amounts of synthetic inputs deliberately applied to soils [for whatever reason or purpose], while the perennials that were   referenced in the article like Spotted Knapweed & Dalmation Toadflax have actually decreased. So why was that ? Are not those two plants also noxious invasive weeds ? Yes they are, but they are not ruderals, they have mycorrhizal roots and mycorrhizal fungi will disconnect in the presence of excessive synthetic nutrient inputs. They are invasive weeds in the sense that they originate from eastern Europe and Asia. Minus the checks and balances from their former ecosystems they then thrive and spread in North America. But they are also mycorrhizal hosts. Clearly human ignorance which breeds irresponsible decision making in so many areas of life have snowballed to the present out of control domino effect we find ourselves in. We are battling Nature instead of working with nature for a solution with an elite few making a profit off the misery of others. Nature has always had the most efficient solutions for balance and high yield success through it's genetic programming for 10s of 1000s of years irrespective how anyone says it originally got that way. Now take a look at another area [land restoration projects] which once again illustrate the how the overuse or reliance on mechanized innovations and synthetic chemicals cause setbacks and delays in plant community restorations. This example below comes from the Coachella Valley which is also located in Southern California just north of Imperial Valley. About the year 2001 a report came out on the success of ridding a desert oasis area known as 1000 Palms of an invasive tree called Tamarisk which dried up the streams and ponds and ruined the environment for the native palms and other desert oasis plants and animals which depended upon them for food and shelter. There were several methods and techniques employed like bulldozing, synthetic Chemicals and old fashioned hand clearing. There were two outstanding references of an observation which serve to illustrate the two superior & inferior methods for success from a single sentence in that whole report at the bottom in the last paragraph that spoke volumes to me. As far as I know, I am the only one who has ever caught this important gem of an observation:
"Most areas were cut by hand, thereby selectively cutting out the tamarisk while leaving the native shrubs unharmed. Only a 7.5 acre (3 ha) section that was heavily infested (> 95%) was cleared using a bulldozer."
"In the 7.5 acres (3 ha) that was bulldozed, natives established much more slowly than in the hand-cleared areas."
(Source)
So two main techniques employed at this restoration site. One was the commonly used conventional mechanized version by way of large industrial piece of equipment we call a Bulldozer with rippers and the other was the use of volunteers to hand clearing and selectively cut out the cancerous invasive plants within the ecosystem and leaving only the healthy native ones. Okay I get the Bulldozer because it is fast and efficient at eradication and the clearing by hand takes recruiting otherwise busy volunteers and a lot of sweat. But okay so what ? It's the long term goal that we are looking at here if indeed there is a noble goal. One leaves a healthy intact mycorrhizal grid under the ground with cover and the other sterilizes the landscape as some sort of clean slate or blank canvas ready for natives to be replanted by spreading seed on the ground and raking it in to germinate and rebuild the ecosystem. One fixes the situation more permanently with little maintenance afterwards and the other being a quick fix will have to be revisited again and again, year after year and still not get it correct. I immediately recognized the differences and reasons for both success and failure [or delay]  because of my own practices on my acreage up in the San Jacinto Mountains which tower over the Coachella Valley. Prior to moving onto my land in 1985, the previous owner had cleared with Bulldozer two large patches of chaparral down to the clean decomposed granite. Other areas were cut and cleared by hand. In all those 20+ years of living there, the cleared areas by Bulldozer always experienced a fight with weeds and attempting to plant any chaparral natives back over the cleared patches of land was always a lengthy process with only a few ever making it. However, in Chaparral area where some places required removal by hand, the ground never suffered. In fact where I would remove a single shrub to make room for a tree seedling to be planted, establishment success was always 100% as opposed to maybe 20%-30% on the bare soils. The reason of course was that the new seedling was instantly inserted into a healthy mycorrhizal grid which hydrated and nourished the young delicate seedlings and the other area had no grid for successful tree establishment which left seedlings to their own struggle for survival, hence the highest failure rates. This was the same method I followed after helping my former landlord Ken Dawson of Terwilliger establish a forest in the chaparral a few years previous. His property was in the Terwilliger part of Anza Valley and considered at the edge of high desert. It was mostly Chaparral covered [Manzanita, Sugarbush & predominently Redshank or Ribbonwood]. 

image mine: 2013

Large specimens of all three chaparral species were left intact by use of a small scale one man backhoe [the size of a small garden Kubota tractor] which was expertly used to surgically remove any unwanted vegetation to allow space for bare root tree planting without damaging other healthy shrubs. All the San Bernardino National Forestry officials & the Nursery at L.A. Moran up at Davis where we purchased those bare root pines said it would never work, especially if we didn't strip clear the land bare from competing brush. The reality of course is that the responsible science-based research being done today has found that the "Survival of the Fittest" religious dogma no longer holds water. The truth is that in mycorrhizal networked ecosystems, there is a mutual cooperation of all the organisms to ensure the health and survival success of all the members of the plant community system.  The chaparral plant community also has some of the deepest plant roots known to bore through impossible soils. They perform an amazing biological function of physics called hydraulic lift and redistribution of soil moisture which I'll reference below. The ONLY time this is  found in conflict is when the wrong soil conditions allow ruderals to invade a mycorrhizal system which has been destroyed through bad land management. Tilling, synthetic inputs, excessive use of fire, and last but not least irresponsible overgrazing by domestic animals with no wild instinct smarts to move on all contribute to long term damage.

image: mine 2013
As you can see the Chaparral, in this case Redshank or Ribbonwood is still intact and thriving, yet so are the Jeffrey and Coulter Pines. The soils on this particular property are extremely shallow with many boulders and fractured rocky soils under the ground. Still the system is a giant success because of replicating nature, even if we didn't realize the full impact and knowledge at the time in what we had done. I later went back and inoculated some areas with an ecto-mycorrhizal fungi from Plant Health Care Inc called Tree Savor Injectable which contains only a single species of Pisolithus tinctorius, which is an ectomycorrhizal fungi. The needle holding capacity of most all those pine trees were 4 or five years which is excellent proof of the system's self-sustaining function even during this present west coast drought which has hit all of California. I'll post a link below in references.

Collective Intelligent of the Enlightened Higher Lifeforms versus the Primitives ???

So what is it exactly that is going on under the ground that makes these specific instances either a  success story or miserable failure ? It is the practices that either a landscaper, gardener, farmer or forester chooses to employ along with other methods of sound or irresponsible land maintenance. Many believe that the Scientific advances of our modern world are the only thing that will save mankind. But the exact opposite is true. Take for example the image at the right here of agricultural soil which has been worked decades utilizing all the modern day science-based tillage practices coupled with Synthetic inputs. The round spheres are fungal spores and these were culled from 25 grams of industrial agricultural soil. The photograph was taken by Dr Wendy Taheri who is a Research Microbiologist who today spends time educating and helping American Farmers who are hungering for a change. BTW, those tiny white round dots are not spores at all, but nematode eggs. Now compare that photo with the photograph below.

Image Dr Wendy Taheri
This photograph here at left is a mere one gram of healthy natural prairie soil as compared to the contrasting photo above which you may remember was 25 grams of industrial agricultural soil. Notice the difference in spore biodiversity count and the high density concentration ? This could also be illustrative of most any forest soil or holistically managed farm commercial soils where large diversity of perennial cover crops are used as hosts which encourages diverse numbers of these endo-mycorrhizal fungi. The above result is where no tillage was practiced and no chemical inputs were ever touching this soil. The bottom soil photograph is the result of supposedly primitive microbes [according to the religiously driven scientific dogma] and the top photograph is the result of science-based industrial agricultural practices of intensive plowing, synthetic chemical inputs [fertilizers, herbicides, fungicides & insecticides] and last but not least the GMO plants which are believed to be improvements on nature's flaws by the Biotechnology industry. All of these brought to us by superior higher collective human intelligence. I can only imagine that the ongoing choices by the majority of farmers, landscapers, foresters and the average home gardener is the imaginary misunderstanding & assumption that the holistic biomimetic practices are more work and sweat with little results to show for the hard work. The reality is that it's the exact opposite. To conclude, let's go back to Dr Jerry Glover's National Geographic Gallery.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now the Gallery below of the art show I opened up with Dr Jerry Glover and National Geographic
National Geographic & Dr Jerry Glover

Here, Dr. Jerry Glover works in a soil pit at the Land Institute in Salina, Kansas with a garden host fitted with a jet nozzle to expose what the rooting structure on two entirely different plants look like. On the left, we see the deeper roots of a perennial wheatgrass are displayed, while on the right we see the more shallow roots of an annual wheat are visible. Notice the side by side contrast below ? The exhibit theme was to demonstrate how the bulk of a prairie grass plant exists out of sight, with anywhere from eight to fourteen feet of roots extending down deep into the earth. Now why should any of that matter ? Besides being incredibly larger in size, these hidden root mass infrastructures accomplish a lot in storing carbon, nourishing soil, increasing bioproductivity, and preventing erosion.  Unfortunately, most of these productive, perennial grass functions of the past are more rare than they once were. This is because they have been replaced by ruderals (annuals) which live a mere few months (six months if lucky).



Common annual variety of annual Wheat here are contrasted next to perennial Wheatgrass. Notice perennials, which come back year after year have a root system which will grow to a depth of few meters, while the annual varieties perhaps a mere foot. This is also illustrative of all ruderals versus perennials in the wild setting. A farmer or rancher with a pasture of abundant diversity of perennials is going to weather the dry season or even drought much better than say those common western states pastures where short lived ruderals such as cheatgrass and other annuals [runderals] reign supreme. This is why many western rangelands and pasture can only have a limited use early in the year. What is most important to a pasture is having a large biodiversity of perennial plants dominating the vast area which encourages an underground  microbiological community of beneficial mycorrhizal fungi and healthy nitrogen fixing  bacteria to allow the soils to breathe. Any rainwater falling on such a landscape will fully percolate into the earth as opposed to running off. This is important to underground storage of water to be tapped into later in the dry season. In times of heavier rainy seasons, several meter deep root infrastructures may also facilitate a process called hydraulic descent which may also help restore underground aquifers and replenish natural springs. The other being hydraulic lift & redistribution, but more on that below. Again, these are also things which even many farmers who do practice  biodiverse perennial cover crops may be completely ignorant  themselves of the full line of services being accomplished by perennial plant root systems other than mere water percolation through healthy aggregated soil alone. More on that phenomena below. But here is a link to the root system galley:
(National Geographic Deep Root Gallery)
Now take as another example the common picturesque California Oak Savanna settings that are often romanticized in photos. 

Image - Mine (2013)

Santa Ysabel Open Space Preserve (Oak-Grassland Savanna)

This photo above is in my home San Diego County in Southern California. While it is picturesque, the historical view with these Englemann Oaks would have had low interior sagescrub or chaparral growing all around it as opposed to these nonnative grasses. These grasses were created by ranchers in the early years to raise cattle. But land management practices from northern Europe and back eastern United States just never worked out here in the west. Africa had the same problems with Europeans ignorant of local ecosystem functions imposed northern European land management practices with domestic livestock which had disastrous consequences. The Cheatgrass dominance in the west also has negative implications in the fight against climate change. Cheatgrass and other ruderals are the worst in terms of carbon sequestration. In 2006, researchers found (Here) that the invasion of cheatgrass in the West had turned some areas from carbon sinks to a net source of carbon. The invasion of cheatgrass and all nonnative ruderals altogether have released up to nearly nine million tons of carbon into the atmosphere and will likely release far more as time goes on. Throughout the California Savannas where Cheatgrass and other ruderals now dominate, many areas often burn annually and actually thrive as a result of this constant burning, whether prescribed, accidental or intentionally set fires. They also have a lousy shallow root system which means that far less carbon is stored in underground root systems than was once true of the native perennials like chaparral or even biodiverse species of prairie plants in true Savannas. There is something else the ruderals cannot assist in accomplishing and that is both hydraulic life & redistribution of water for the beneficial function of the entire system. Aside from the loss of a mycorrhizal grid underground network there is something else missing. These two subjects are mostly a mystery of sorts to most people, but they are important phenomena to have an understanding of if your farm, ranch landscape, gardening or habitat restoration project are to be a success. Admittedly, even scientists do not discuss much about the phenomena to the public in general.
Importance of Hydraulic Lift & Redistribution
This is one natural phenomena which most likely no longer functions properly if at all in most modern day farm pastures and Ranch grasslands and sadly there is not a lot of discussion about it. Those old growth plant root infrastructures provide an invaluable service in the summertime of hydraulic lift and redistribution of water resources from deep in the earth up to the surface layers. But only certain specific plants with the deepest root systems can perform this task of drawing up water, sending it laterally toward other plants by means of the mycorrhizal grid for the night time benefit of other shallower rooted plants. This is the reason some holistically maintained pastures, even in traditionally dry western geographies have a healthy green even during the dry season. The animated illustration below often used by Professor Todd Dawson reveals how the system actually functions.


But there is even more than hydraulic lift at play here. Some way somehow the water has to be driven deeper than mere soil percolation would allow. This is where an reverse in hydraulic function of root systems must come into play.
What has happened to Hydraulic Descent ???

I once read where researchers once discovered something interesting about the common Mesquite Tree of the deserts in the southwestern United States. When the tree is dormant and not visibly growing above ground during the winter rainy seasons, they perform a phenomena called hydraulic descent where their root systems collect as much surface rainwater percolation as possible and pump it deep into the earth. Now, Mesquite & other desert trees and shrubs have some of the deepest taproot systems known in the world. They can actually bore through the earth down to a depth of a couple hundred feet. Please take note of the animation above. What effect has the loss of this phenomena had on large aquifers and natural springs ? How much does such a phenomena have on actually benefiting groundwater recharge beyond helping pasture to maintain green ecosystem viability during the dry season ? What practical applications can be applied in biomimetic inspiration in creating technological innovations such as irrigation systems which save water as opposed to the present wastefulness we have now ? My reasons for bringing the subject of hydraulic lift - descent & redistribution into the discussion is that they cannot be ignored as a naturally occurring phenomena either in the wild, farming, landscaping & gardening. When w landscaper prepares a design on any new project, all such consideration of these remarkable mechanisms alone with the microbiological nanomachines we've looked at earlier should be considered for the long term viable life sustaining system you are wishing to establish. Same with the farm, ranch or habitat restoration. People need to think in terms of their projects being a living mutually cooperating biological machine. While it's wonderful that farmers, professional landscapers and your average home gardener are thinking in terms of practicing a holistic biological approach minus the chemicals, it's also important to widen out and have a peripheral view other other factors that provide checks and balances into the system. For example attracting the beneficial predators both large and small. I'll provide more links below in references. 

So let's recap what we know!
All plant ecosystems basically work and function identically with a little a little tweaking taken into account for climate and geography. The purpose (don't look at the term as a dirty word) of annuals is important in that when land is disturbed they quickly cover the ground. Most of their capabilities are offensive with very little resources being used in defenses against predators. Creating an abundance of seed to replicate themselves is what they do, but irresponsibly land manage and you provide an out of balance scenario for them to explode upon the landscape. All Tree, Shrub and Prairie systems are heavily mycorrhizal. Mycorrhizae in all systems of management dislike over fertility or nutrient abundance. Bacterial systems limit root infrastructure and in farming excessive synthetic nutrient inputs are nothing more than a numbers game where it is hoped that 20-30% sucks in somewhere around the plant. Because mycorrhizae is mostly absent from such systems, weeds (ruderals) thrive and more synthetic inputs are needed to rid the system of unwanted plants that nature would have otherwise kept in check. Excess synthetics end up percolating into the earth polluting groundwater or as runoff into aquatic systems during the heavy part of the rainy season creating further pollution and ecosystem disruption. All areas of human endeavour when it comes to plant system management like habitat restoration, forestry, farming, ranching, landscaping right down to home gardening either benefit or suffer depending on how closely you mirror your techniques to how nature really works. Tillage is also another limiting and damaging practice to mycorrhizal soil structure. Limiting tillage as much as possible will maintain this life sustaining system underground which in reality is not so primitive after all as science would have you believe. Take all of these micro-organisms away and see how time we higher lifeforms have left to live. If life truly is a mere mistaken bundle of compromises, then what the heck, maybe the Biotechs and Agro-Chemical companies are doing nothing wrong and we should just accept the consequences of putting our faith and trust in these toxic know-it-alls. 
In Conclusion: The Winners & Losers
New technological advances by mankind's Elites have seemingly made life easier for the rest of us when we only look at them from an on the surface viewpoint. These bio-innovations created in some high security lab however have put mankind and the natural world at risk. The fate of the world is being placed into the hands of unaccountable elites in bed with powerful political interests who speak from one side of their mouths of their products being the result of ethical responsibility while at the same time being obsessed with the pursuit of fame and personal enrichment out of the other side of their mouths. The problem is our messed up world is the result of a gross lack of Bioethics. These people know full well what their products are doing, but their strategy is to play the dumb card. When a newer consequence strikes, they simply create another synthetic solution to treat the symptoms while totally turning a blind eye to the cause. The pharmaceutical industry works the same way, but hey, are the also not related ? So from a short term monetary, fame, glitter and glory standpoint there are certainly those who appear to come of the winners. Farmers are also the real losers, not the agro-chemical corporations. If any farmer actually becomes truly informed, educated and understands that most of their success is in changing practices as opposed to spending vast amounts of money on synthetic inputs along with magic seeds, these giant corporate entities would fold. Can you now understand the reasons for vast amount of financial resources being funneled into these damage control public relations lobbying by corporate business interests ? The vast majority of other lifeforms including humans will also lose out in the end. I know of no real solution as far as implementing or reversing the damage done on a massive global scale. You all read the News lately, so you tell me. That doesn't mean the information and understanding on how to use the clean viable information doesn't exist. It does. But there always seems to be something powerfully negative out there to throw the proverbial wrench in the works. The best that can be done is for those few individuals who actually get it to make practical application of what they know to use out on the farm, ranch, landscape or garden and allow the light of success to do the talking for you.

 How long can people really keep trusting these fallible researchers to be bio-ethically responsible ? Ask yourself, what's been their track record thus far during this modern age of enlightenment ?

Mistletoe: Former Demonized Plant Turns Out to be a Great Helper

Photo Credit: Duke University
Mistletoe is more easily identifiable in the Fall and Winter when deciduous trees have lost their leaves. Yet there are numerous other species of Mistletoe which exist on other evergreens, cactus, Chaparral, Eucalyptus, etc. Often demonized and used as an excuse for  timber harvesting and Control Burns, now it appears to be an actual Keystone species necessary for a health Vegetative system and it's occupants.


Wow, who knew it had other uses ? Well, Scientists should have known this all along. At least the ones who are in charge and trust of protecting the natural world and the authoritative control over official policies for responsible the land management. But as with other areas of Science back in the 20th Century, this hasn't always worked out well for the natural world. Government agencies with official oversight of Natural Resources have always managed the landscape from an exploitative money making venture perspective. Now that our natural world is so badly degraded at the start of the 21 Century, it is only now we see the real true value of things that have been either completely lost and not ONLY on the verge of  extinction, but now Science is actually taking a harder look at things assigned negative labels such as a disease, infectious, invasive, ugly, worthless, parasite and so forth. Ultimately, they now have to try to view various components of Earth's Ecosystems from a purposed perspective (something often considered by some as heretical in the past), just what benefits are derived from organisms like Mistletoe deemed worthless, evil or invasive.


Credit: US Forest Service
Words/Terms like these ones here  'invasive' - 'parasite' - 'infection' etc, have often in ignorance done more to hurt our understanding of some organism than to further it. To be honest, Mistletoe in my book isn't any of these and I'll conclude further on down as to why that is so. For more than a century, Mistletoe has been long thought to be a destructive trees murdering organism for which this great harm to human resources must be eradicated. I wanted to comment earlier when the research paper came out by David Watson, a researcher at Charles Sturt University in Albury of New South Wales in Australia, but I was delayed. I really wanted to document & reference for you some of the usual bad forest policies used in the past to eradicate or control what were considered infestations of Mistletoe in regards to Control or Prescribed Burns. But first, here is the latest article came out in the around December 17th 2012. Here is the link and Abstract and my comment after that. (by all means read the entire paper)
The Royal Society: "Mistletoe as a keystone resource: an experimental test"
Abstract:
"Various entities have been designated keystone resources, but few tests have been attempted and we are unaware of any experimental manipulations of purported keystone resources. Mistletoes (Loranthaceae) provide structural and nutritional resources within canopies, and their pervasive influence on diversity led to their designation as keystone resources. We quantified  the effect of Mistletoe on diversity with a woodland-scale experiment, comparing bird diversities before and after all Mistletoe plants were removed from 17 treatment sites, with those of 11 control sites and 12 sites in which Mistletoe was naturally absent. Three years after Mistletoe removal, treatment woodlands lost , on average, 20.9 percent of their total species richness, 26.5 percent of woodland-dependent bird species and 34.8 percent of their woodland-dependent residents, compared with moderate increases in controlled sites and no significant changes in Mistletoe-free sites. Treatment sites lost greater proportions of birds recorded nesting in Mistletoe, but changes in species recorded feeding on Mistletoe did not differ from control sites. Having confirmed the status of Mistletoe as a keystone resource, we suggest that nutrient enrichment via litter-fall is the main mechanism promoting species richness, driving small-scale heterogeneity in productivity and food availability for woodland animals. This explanation applies to other parasitic plants with high turnover of enriched leaves, and the community-scale influence of these plants is most apparent in low productivity systems."

What impact does the Dam
of a Keystone Species like a
Beaver play in an ecosystem ?
Mistletoe = Ecological Keystone Species ? This would be a living organism that has the biggest impact on life around it within an ecosystem. But who would have thought that of Mistletoe ? I mean it is often ugly, rangy looking, certainly poisonous. So what possible worth or value  is it ? It's funny, I was reflecting on this negative attitude on this plant and similar attitudes towards other species plants, animals, birds, etc (like various Chaparral Plant Community Species) from a Human perspective and realized that humans treat and judge other humans the very same way. Or is it the other way around ? Could it be that mankind's often inhuman treatment of other cultures, races, class distinctions etc has been transferred over from their abuse of the natural world's resources and that explains the sad state of affairs in our societies as well ? I do believe it's both that reflect the mirror image of each other. But let's get back to examples of other kinds of Foundation Species which will illustrate the importance of the role a Keystone species plays in any habitat and get a better than average understanding of what and how Mistletoe fits just such an important niche in nature. How about a Beaver's Dam ? A Beaver moves into a completely new area and then by his dam building, physically and dramatically changes an entire wide area even well beyond it's immediate shorelines. 

Wikipedia
This impact of a Beaver's Dam building in create a lake or even small pond are huge indeed. Clearly as illustrated above, there are the obvious reasons. But even still, more so even far away from beyond the immediate vicinity of the pond or lake. Underground water tables are raised. Riparian woodlands which will be extensive around the banks will not only provide shelter and other habitat and food resources, but also the fact that their specific nature with regards their root systems in being both Endo & Ecto Mycorrhizal make them perfect water shunts or hydraulic transporters to other species of forest trees and chaparral far away from the water source. That in turn creates further life opportunities elsewhere.

I truly enjoyed reading from the study here, about some of the benefits that Mistletoe actually provides in the plant communities. I've always known about the benefits to birds as far as food and nesting, but the intriguing benefits of Mistletoe leaves to the forest floor was very interesting. Again, who knew ? Who would have thought Mistletoe leaf litter contained further richness for which to effect other life on the forest floor ? So the Mistletoe actually provides more richness in nutrient drop debris, than simply it's own leaf litter. And as far as that label "Parasite", I hate it !!! Why ?  Because the reason is, it's inaccurate of what I would consider a true parasite, you know, one that sucks almost all the life from it's host and gives nothing back ? But Mistletoe is different. scroll back up and look at the colour of that Mistletoe at the top of the page. Notice all the green ? That is Chlorophyll and for what purpose is Chlorophyll used for ? The manufacturing of food. So it's doesn't exactly draw from the tree's carbon stores what it needs, it manufactures it's own.  What it does do is create roots within the tree's branches and trunk and draw water and nutrients. Mycorrhizae however does draw from the plant carbon sugar stores and yet we don't consider it a parasite. Why ? Because it actually increases nutrient and water uptake by the plant by 200% and you can actually see improvement. It actually makes the plant work harder, but more efficiently. So one has to wonder what other things Mistletoe may be giving back to the tree in the way of beneficial Chemical exchanges. We do know that through the mycorrhizal network that plants can make chemical exchange between all sorts of trees and shrubs. So mycorrhizae gets a much nicer word of association through Symbiosis

There is no doubt that under specific circumstances, the over abundance of Mistletoe in a tree which may be in a weakened state,  can overwhelm and even kill the tree. Some like the Dwarf Mistletoe which are perhaps not of the Greener variety and colonize pines, maybe have more of a parasitizing nature when out of control caused by imbalances. However, if there is one thing we all do know NOW, the natural world when it's left in a pristine healthy state with all it's various living components for which we NOW know all cooperate and help one another as opposed to the mistaken dogma or doctrine of "Survival of the Fittest", doesn't normally work against itself, UNLESS something gets out of balance. Mostly, if it does, it has a human stain of ignorance shackled by greed and selfishness as a motivational factor. The same could be true, and there is evidence that it is, with much of the mistletoe degradation of forested ecosystems around some places on Earth. At times however, out of control mistletoe can leave clues behind as to why conditions were so favourable for it's excessive spread which has been a result of human mismanagement of the land.  Take for example this photo below.

 When I hear of certain specific reasons (excuses) made for why trees needed to be harvested to eradicate something or even plans for a prescribed or control burn to eradicate something, I know that as a general rule, some other motive is behind it. While there may be real circumstances where there could be a real need, how or why did such an overwhelming outbreak occur in the first place ? Take a clue from the photo above of the clearcut forest. They said on the forestry link that it had to be done because of the invasive Mistletoe. Really ? See anything odd or unnatural about that photo ? Yes, of course, it's a dead give away. It's not a normal occurrence for Jack Pine or any other species of tree to grow in a monoculture setting which looks more like row crops of a corn field somewhere in Iowa. Clearly, the unnatural circumstance of the Industrial Forestry created in the first place by humans is to blame, but that is not what gets the blame. Mistletoe is the evil villain. The above circumstance also justified taking out non-infected areas also. Open this link below here from the Warnell School of Forestry in Georgia and scroll on down to page 20 view the survey chart which shows the results of three Surveys taken in the U.S. states of Kentucky/Tennessee hardwood forests. The percentages shown for the majority of Mistletoe colonization are mostly tiny to none per species and yet the four highest percentage species listed certainly are not life threatening to the woodlands either. This is because the forest is extremely biodiverse and not monocropped like the Industrial Tree Farm of Jack Pine in the above photo.

There are numerous Mistletoe species and many of them host specific, which means they prefer one or two kinds of tree. The more biodiverse, the far less problem of an entire wipe out of an ecosystem. BTW, read that entire link. There are some fascinating educational information on Mistletoe life cycle and construct on that paper. Below is a photo of the use of prescribed burns for control.

Cut, felled and 'prescribe burn' of supposedly Mistletoe 
infested Lodgepole pine in the United States.
Recently I wrote about the Santa Rosa Mountains which are above overlooking Palm Springs. Sometime back in the 1930s, a switched back trail called the Sawmill Trail was constructed to allow Logging companies back in the 1930s to harvest Jeffrey Pine trees. Talking with the man who built the road, Jay Dee McGaugh, he said the excuse the Forestry gave them for clear cutting the Jeffrey Pines  was that they were all "Bug Trees", which I took to mean they were all infested with some species of Pine Beetle. Knowing the way politics was and has been, one has to wonder if the real truth of the matter was more of a money making venture as opposed to any ecology. Guess we'll never know for sure, but no replanting effort was made and the forest tree line no longer extends lower down Santa Rosa as it once did. Recently another similar Science report has come out and exposed the cause for the global increase of an explosion of Jellyfish populations everywhere around the entire earth. Of course the report doesn't blame the Jellyfish, but does expose the human cause of pollution throughout our planet's oceans for the favourable conditions which facilitate & trigger their rapid increase. My point here is this. There are all sorts of living organism on this planet that are out of balance. Some of the out of balance circumstances even in your own yard's landscape like insect pests, weeds or whatever may be a fault of your own, but unknown to you. Before applying some irresponsible damage control measure by use of other science based innovations like chemicals, should be avoided to see if there is a more ecological solution which would be more viable.
EurekAlert
Common scene of Japanese Fishermen fighting to keep Jellyfish from their nets. These creatures are also consuming the fish they may catch. But will the Fishermen blame government and big business for the off balanced abnormal conditions created by industrial pollution and demand something be done about it ? Or will yet apply another negative label to be attached to a creature who simply responds to genetic instructional instincts as triggered by it's environment for which humans are responsible ?

These two links here are of some of the negative uninformed mentality which rules. Further below are some more interesting links. You can actually Google more info and obtain 100s of other informative links with the same bad science viewpoint towards Mistletoe. In the mean time, when you next go walking on a nature hike, give consideration to those darker green lush patches high up in the tree's branches and give some thought to all the other biodiverse richness of life they provide to the entire system
