When Mycorrhizae defies the Scientific Orthodoxy on what Plant Hosts they'll colonize
Dogmatic Scientific Consensus gets blown out of the proverbial saddle once again!
Sorry, I couldn't resist. In most of the text books and science literature promoting the wonders of mycorrhizal fungi, both Ecto (EM) & Endo (AM) Mycorrhizae generally are categorized into lists that highlight the main types of trees, shrubs and other plants which both of these differing fungi will supposedly ONLY colonize. The lists are almost as a sort of etched in stone hallowed religious text that cannot be altered without facing some sort of backlash from the established Scientific Orthodoxy which establishes truth. Frankly, the Natural World couldn't care less what the Science Consensus gang may assume to be the prevailing worldview. Take for example the Chaparral Plant Community. The conventional thinking is that aside from Scrub Oak, Manzanita and a handful of other plants, most shrubs are Endomycorrhizal. But as a change of direction and surprisingly back in 2005, it was the US Forest Service who published a report entitled:
"Greasewood or Chamise( Adenostoma fasciculatum ) normally forms arbuscular mycorrhizae with all genera found in the region. However, during wet years (El Niño), we found EM associated with its roots and EM fungi in the stands (Allen and others 1999b). There was a high diversity of fungi ranging from Cenococcum and Balsamia spp. (ascomycetes ) to a variety of basidiomycetes such as Pisolithus sp., Cortinarius spp., and Hysterangium separabile. We also found a new species of Rhizopogon : R. mengei (Allen and others 1999a). This is an important finding , since all other known species of Rhizopog on are associated with conifers. In addition, we sequenced the dominant fungus found on the root tips of Chamise, and this fungus was an unknown species of ascomycete, most closely related to Sarcocypha emarginata (97 percent similarity in t h e sequence alignment of the 5.8S region, 63 percent similarity in I TS1, and 59 percent similarity in ITS2), a common fire-following fungus. There are clearly plant/ fungal symbiotic combinations that we do not understand and have yet to explore."
"Although we have focused on Coast Live Oak and Chamise, it must be noted that there are many other EM plants in southern California. These include all other species of oaks, all members of the Pinaceae, and Chinquapin ( Chrysolepus semper-virens ). In our region, these never have been surveyed comprehensively."
Maverick Example #1-Chamise (Adenostoma fasciculatum) &Pisolithus/Rhizopogon
The final quote in the very last sentence says it all, "In our region, these never have been surveyed comprehensively." No kidding ?The fact is, nothing is etched in stone when it comes to understanding Nature. If it was, our natural world wouldn't be in danger from global ruin as it is at present. The above admission and findings regarding ectomycorrhial colonization of many chaparral shrubs should takes us further in our understanding how to restore habitats and make practical application within the urban landscapes of Southern California. Why the very idea of Chamise or it's other not so flattering label Greasewood being ectomycorrhizal is almost unheard of. It's value to the natural world has been clouded by it's being demonized by many insisting that it alone is responsible for some of the worst wildfires in Southern California. Colonization by symbiotic various species of Ecto-Fungi, especially Pisolithus & Rhizopogon during wet rainy seasons (El Nino Events) is interesting and almost speaks volumes about the information encoded within the Chamise plant's DNA for assisting and facilitating Pine & Oak tree establishment during these wetter periods like El Nino events. It almost has the appearance of a cooperative strategy within an entire ecosystem to mutualistically help the entire plant community advance itself towards woodland re-establishment. This clearly exposes the ignorance and arrogance of many powerful Forest Managers who have conveniently and deliberately (no doubt for financial gain) ignored the beneficial roles chaparral plants play in forest establishment and lifetime health of the forest. It is clear that during drier periods, such lack of symbiosis would prevent tree seedlings from unsuccessful establishment due to lack of moisture, even within the subsoil and also at the same time taxing the survival mechanisms of the Chamise itself, who although being a tough fighter in hot drier regions, also has it's own limits. BTW, I originally alluded to Chamise ability of helping to advance forest trees and other oak woodlands over a year ago in May of 2013 last year. It's one of the best at further Parry Pinyon establishment. Given the new ectomycorrhizal connection revelations during extreme wet years, this along with it's incredible ability at hydraulic redistribution makes perfect explanatory sense for the successes in some areas regarding woodland increase.
Maverick Example #2 - Date Palm (Phoenix dactylifera) & Carob Tree (Ceratonia siliqua)- Pisolithus tinctorius
First, a word about Carob Trees and Pisolithus tinctorius. Without going much into this, I have created a later post (2016) and I am adding it here. Carob trees is another one of those interesting trees which the Dog Turd Truffle (Pisolithus tinctorius) will easily and readily colonize and remain for many years. I first discovered this not by reading any literature on the subject, but rather first hand observation back in the later 1990s when I did bank promorional work at California State Univerversity of San Bernardino in Southern California. Their ain parking lot was almost totally Carob Trees and truffles were everywhere in the street islands and parking area planters. It was only several years later I even found any literature and it was by researchers in the Middle east & North Africa.
Well we all know what a Carob Tree is, but it may surprise many to find that Pisolithus tinctorius will conolonize this tree. Not me, like I said, I have known of this since the middle 1990s. So here for the record California State University San Bernardino, is a free and accessible collecters hotspot with it's massive parking lot where Carob Trees can be found in the parking islands you will find many old dried Pisolithus truffles everywhere. I'm serious, go see this parking area for yourself. I'll be passing through there in two weeks on my way to Phelan, I'll take photos if I can. I know because this was one of my favourite collecting areas back then. But the real exciting shocker for me was the research literature of Date Palm (Phoenix dactylifera) being colonized by Pisolithus tinctorius. I mean all of the literature and text books insist this tropical or sub-tropical loving tree is strictly an endo-mycorrhizal plant ONLY. And yet once again research has proven otherwise. A 2012 study by Moroccan researchers who collected Psiolithus truffles from Eucaplytus woodlands in Morocco for acquiring spore source for Pisolithus inoculant for testing both Carob & Date Palm actually proven colonization does take place. Again this is contrary to what many of the approved conventional textbooks say with regards this subject. Clearly both trees are a major food source for Middle Eastern and North African peoples and cultures. The Arab researchers therefore had a strong motive for finding if such a possibility did exist when would greatly enhance their agricultural practices with these two trees.
"In this study ectomycorrhizal plants frequency after inoculation by Pisolithus tinctorius in this study was 6.66% for Date Palm and 10% for Ceratonia Siliqua . Thus , Phoenix dactylifera and Ceratonia siliqua were ecto-mycorrhized for the first time in our experience conditions."
Application of mycorrhizae in sustainable Date Palm cultivation
Images -(German BioMyc™ Vital, Germ 2009)
Date palm (Phoenix dactylifera) is a significant and developing crop especially in the Arabian Peninsula, the Middle East and North Africa regions. The area under cultivation of this tree is increasing annually. Date palms usually grown under harsh and unfavorable growing conditions with low rainfall and high rates of evaporation as well as in soils with low organic matter and nutrient deficiencies. Hence, date palm cultivation becomes dependent on application of high levels of fertilizers as well as on irrigation. This may lead to salinization of soil and leaching of nutrients to deep soils that might affect ground water. Therefore, it is important that date palm plantations are managed in a sustainable way to reduce the impact of date palm cultivation on ecosystems while maximizing dates yield through using such practices as mycorrhizal fungi technology. The application of mycorrhizal fungi technology is an option that can benefit both agronomic plant health and ecosystems. Mycorrhizae confer numerous benefits to host plants including improved plant growth and mineral nutrition, water uptake, tolerance to diseases and stresses such as drought, temperature fluctuation, metal toxicity and salinity. Mycorrhizae may also play a role in the formation of stable soil aggregates, building up a macro porous structure of soil that allows penetration of water and air and prevents erosion. All of these beneficial effects on plant health and soil fitness mean that mycorrhizae have the potential to increase agricultural productivity and are crucial for the sustainable functioning of agricultural ecosystems. This study provides an insight into the application of mycorrhizae in date palm cultivation."
Clearly, most western researchers, especially in the USA wouldn't have bothered with such an investigation considering such plants are not considered a pressing economic concern as they would to the Arab world researchers, opting instead to believe the prevailing doctrinal literature on the matter regarding Palms and other plants considered strictly to be endomycorrhizal. But this brings me to ponder about what other possible success stories are out there waiting to be discovered. For example, what about California Fan Palms (Washingtonia filifera) and other Palm Trees used in the urban landscape ??? I don't doubt they are strictly endomycorrhizal, but is there a possibility they could also become ecto-mycorrhizal colonized under the right conditions and with the correct species of Ecto, which would allow them to interconnect with other plants in the wild within a wild Oasis setting or an urban landscape scenario in association with other trees and/or shrubs ???

Maverick Example #3 -Alligator Juniper (Juniperus deppeana)&Pisolithus tinctorius
image: Mine
I have my own example which I experimented with back in the late 1990s. My Son and I went on a trip to the Huachuca Mountains above Sierra Vista Arizona while driving up Carr Canyon and along side the road I found a 6 inch high Alligator Juniper seedling I scooped up and took back to my property back in Anza. I planted the 6 inch Juniper seedling within a grouping of mature Redshank or Ribbonwood (Adenostoma sparsifolium). I did inoculate the seedling with a Pisolithus tinctorius mix I purchased from Plant Health Care Inc. Back then I was in continual communication with lead PHC Scientist, Dr Donald Marx and informed him that after a month from the time I inoculated this Juniper, a thumb sized truffle appeared at the base of the plant. This wasn't supposed to happen according to the literature. Of course lots of natural phenomena actually happen which is not in the conventional literature and textbooks. Dr Marx had me send him pictures of the tree with the truffle for documenting sake. Unfortunately I never received a reply and in all of the present literature out there, I still find no reference to colonization between the two species of organism. Not surprising since most religious orthodoxies resent being challenged as to what they consider TRUTH. This tree today hasn't grown to much, only close to a meter perhaps, but healthy enough to show promise. Given the fact that we are all shackled under the present climate change and extreme drought condition in SoCal, it's remarkable that this tree has survived at all. There are of course a number of things to also consider here. I have always had my greatest success in Southern California mountains establishing trees in remote areas and landscape by associating them with Adenostoma sparsifolium and Adenostoma fasciculatum. I had always thought that these extreme deeply rooted trees were potentially some of the best source for success as a Nurse Plant, but apparently there may be more to it than that. It makes sense to me that I have found in the past large Pisolithus truffles several meters away from target trees, like my Black Oak (Quercus kellogii) where I found numerous truffles which never existed on my property previously before suddenly appearing 10+ meters away from the Black Oak I later inoculated and within mature bases of Redshank or Ribbonwood. Same with Coutler and Jeffrey Pine that I have planted and have done so successfully and far far away from any irrigation source beyond the first year I might add. There is a wealth of information here and I hope more researchers follow this lead and actually do something with the information once it's published, instead of shelving it in some obscure place on the Net only to be stumbled upon by occasional accident from someone searching out of curiosity as I did. Sadly, the California Chaparral Institute has not spoken of this and they are the very ones who should be spearheading the lead in doing so. I'm becoming increasing disappointed with them as they are persuing more interest and direction in typical eco-activist lawsuits and radical protest movements. This world's powerful Elites in the Timber Industry and Forestry are also in terrible need of replacing things out in Nature are ever going to improve. The religious dogma known as "Survival of the Fittest" &Argument from Poor Design have both done far more damage than we can possibly know in our understanding of nature and developing management practices based on biomimicry. Why would anyone biomimic anything when you view the subject as flawed in the first place. Demonizing and eradicating chaparral as something invasive and overwhelmingly competitive in re-establishing a forest after wildfire is a flat out lie. The old archaic thinking of forest re-establishment techniques and innovation based on flawed worldview & false dogmas need to get a grip and change with the times. They desperately need replacing because the natural world cannot afford anymore mismanagement by either side of the issue. Both ideologies have been weighed in the balances and found deficient. We can't afford to have any of these individuals in charge anymore as time is running out. For the average person reading here who actually gets a clue and cares about their own property or habitat restoration project, this is invaluable information regarding ecto-mycorrhizal relationship with chaparral, added to the already deep rooted capability of their root infrastructure along with hydraulic redistribution phenomena. There is no guarantee officials will ever get this revelation unless of course there is some sort of career advancement promise or some other personal profit incentive attached to learning and accepting it. Below are further examples of my own success with community planting pines and oaks within Redshank & Chamise chaparral vegetation. Clearly more than hydraulic redistribution created the successes here. Inoculating with Pisolithus tinctorius also clearly created an interconnection pathway between all these plants. Let's create a new catch phrase, "Mutually Assured Survival"

This is my old place where I planted, inoculated and left to it's own devices a Coulter Pine the very year I left in 2001. It was planted in between those huge Redshank & smaller Chamise chaparral shrubs. Watered that first year ONLY and after that was left to it's own. The present owners cleared the land in front of this tree and put up the fence, but otherwise it was in a remote spot on the property. They did not move there until 3 years after I left and they have said they've never watered the tree. The height and spread are very large (taller than me @ 6.3) and pretty amazing considering the present long drought scenario in SoCal since then. It's also important to take special and specific note of how many years growth of needles are still clinging to each branch whorl. There were actually 4 years of needles still clinging onto the tree which is an amazing feat considering the drought that California is presently experiencing and predicted to get even worse and far reaching over a decade. Of course the credit goes to the way Nature is engineered here. Not only is the mycorrhizae imperative to the health and long term life of the tree, but a huge credit should also go to the two cousins of Chaparral you see here. Redshank & Chamise which facilitate hydraulic lift and redistribution of deeper under ground water resources which actually help hydrate and sustain the young Coulter Pine.

This Coulter Pine was a foot tall like the one in the above photo. It's location is in front of the one above where the Chaparral was cleared around it and a shed built which is in between both trees. However this was not done until 2004 almost 4 years after they were planted and they told me that they have never watered any of these trees. This seedling was actually slightly bigger than the one behind. Again, look at the height here which is much greater than the one above and notice the formation of cones already. This is unusual again given the drought circumstances which are presently hovering over this region and throughout California. What's exciting here as well is the formation of Coulter Pine cones already at this young stage. Clearly this less than one decade's worth of growth and survival can be attributed to the Chaparral which rather than compete, are aiding the tree's survival.

Once again this is the old Dawson homestead where we planted hundreds of Coulter & Jeffrey in 1983 which are now around between 20 and 30 feet high and bearing cones. We left the majority of Redshank, Chamise, Manzanita and Sugarbush. But clearly after inoculation with the PT Mycorrhizae, more happened than just hydraulic redistribution for mutual survival. I clearly have more picture examples of my old place and elsewhere, but the point has been made. Look forward to more research and discovery. In fact, biomimic it yourself and document what happens with photography. Share the results with others. BTW, for the landscapers, remember the importance of following establishment by replicating what happens during wetter years by watering with deep soaking frequently to first couple of years, then tapering off. Clearly this is also important in PT Mycorrhizal coolonization within the chaparral community which assures better tree seedling success.
