"Joshua Tree park superintendent David Smith talks about arson caused fire in March 2018 that burned plants and trees in the Oasis of Mara in Twentynine Palms."
Desert Sun: "After Joshua Tree arson, Joshua Tree National Park takes steps to heal the Oasis of Mara"
Like most all living things today, the Oasis of Mara in 29 Palms is fighting for it's life on Earth
"The Oasis of Mara was first settled by the Serrano and provided them with food, clothes, tools and housing. In one legend told about the oasis, the Serrano were instructed by a medicine man to plant a palm tree each time a boy was born. In the first year, they planted 29 palm trees at the oasis."

"The mesquite trees in the oasis area are also declining," says Neil Frakes - Vegetation Branch Chief - National ParksThis is definitely even more odd. The native desert Mesquite Trees are in decline at this same Oasis ? 😲 Mesquite, Acacia, Palo Verde and Ironwood are some of the toughest desert trees I know when it comes to survival in the harshest of desert climate conditions. They can take any amount of intense heat the summer sun can throw at them as long as they have available water supply. And normally they do as you can see in the illustration on the right hand side of the page here. Once mature, many mesquite trees have an extremely extensive long deep tap root system which grows down 150' to 200' where many water tables can be tapped into. This allows most mesquite no real need for any available surface water which is usually dependent on rainfall. As long as Mesquite is tapped into an underground aquifer, there should be no problem. But these mesquite in the photograph above are clearly struggling and they are having a tough time in a geologic scenario where for perhaps 1000s of years this desert artesian spring has existed. This oasis is located at the end of the Pinto Mountain fault. Many earthquake faults are natural conduits for moving water where it collects and is moved towards the surface. But this sudden lack of water in an artesian spring on a fault such as Mara Oasis is troubling. Clearly one could understand shallower rooted plants like the California Fan Palms and then Cottonwoods having a rough go of things if the surface water table dropped significantly, but dropping so far down that mesquite start to die off ??? Below is a map of the earthquake faults in and around Joshua Tree National Monument.

"A spring is the result of an aquifer being filled to the point that the water overflows onto the land surface. There are different kinds of springs and they may be classified according to the geologic formation from which they obtain their water, such as limestone springs or lava-rock springs; or according to the amount of water they discharge-large or small; or according to the temperature of the water-hot, warm, or cold; or by the forces causing the spring-gravity or artesian flow."

ATTENTION UPDATE (March 27, 2018)
Looks like the Oasis of Mara is now totally gone thru an arson set fire last night (26th). One of the more annoying things is all photos of the Oasis are older photos when it was still vibrant and healthy, no reality of it's poor almost dead condition as of recently. Much the same with the decline of Torrey Pines in San Diego.

"I've lived in 29 Palms since the early 1960s and this is by far the worst the Oasis has looked in that time period. Something needs to be done to save what's left. The mesquite needs to be cut way back for starters because it's stealing water from other plants that need it more, like the Palms and the lone Cottonwood. After all, these palms in the Oasis are our namesake."
The Mesquite at the Oasis are not the bad guys here. But this is common with many people who by nature will demonize one favoured plant over another less loved plant. I clearly do understand the emotion behind the commenter's feelings about the idea of removing the mesquite to save the much beloved and rarer palm as compared to plants from the pea family, but the mesquite are generally more helpful than harmful. In previous posts I've provided this animated illustration above showing the incredible natural hydrological phenomena mesquite are known for. This natural phenomena is known as, Hydrailic Lift and Redistribution. The Mesquite tree is quite often an excellent important nurse tree for other desert plants like young Saguaros cacti. Likewise so are Palo Verde and other desert trees. They can tap into a permanent water source and lift that deep water to the surface re-hydrating their own lateral rootsystem, thereafter feeding it into the mycorrhizal fungal network grid which may be connected to other plants like the California Fan Palms and/or Fremont Cottonwoods. This phenomena is especially strongest at night. So cutting down the mesquite would offer no value, since the mesquite themselves are clearly struggling and in decline. This would not be so if the water table within the fault were at normal levels. It could be that a lack of rainfall and snow up in the San Bernardino Mountains to the west have not been capable of recharging the Pinto Mountain Fault aquifer because of the mega-drought. But I'm not sure. Or it may also be another natural anomaly which sometimes changes hydrological conduits caused by some major earthquakes which have been known to close off and completely shut down age old artesian Springs, forcing their waters to resurface elsewhere. This actually happened historically with the town of St David Arizona south of Benson where artesian springs and ponds began to appear where they never were previously. However in other townsite areas further south like Charleston and Fairbanks where springs and lush grazing lands once existed in the old west cattle ranching days, they actually began to dry up and disappear after an earthquake. Here is the link below to this event and it's a good read. Mind you, I'm not certain if that happened near 29 Palms, but it's one posibility given the historical seismic activity of Yucca Valley which is aligned with the infamous San Andreas fault.

Another player in the proposed Fan Palm removal has not only been the Government, but also the Southern Nevada Water Authority who has stepped in pushing it's own water rights agenda by using the saving of a native fish, Moapa Dace, strategy for which the Palm Trees are said to be partially the blame for the fish's decline. Here are some pertinent quotes:
"Tensions are running high in the Warm Springs area 60 miles north of Las Vegas, where the Southern Nevada Water Authority bought up land to protect a rare fish but has endangered relations with the locals in the process.
Lately, it’s the sound of chain saws that has residents buzzing. Over the past year, workers have cut down some 900 wild palm trees on the fenced, 1,200-acre tract the authority bought in 2007 and now operates as the Warm Springs Natural Area."
"Before the Southern Nevada Water Authority took a lead role in protecting the endangered Moapa dace, the regional agency was widely considered one of the biggest threats to its survival.
For decades, the authority has pushed a plan to tap billions of gallons of groundwater across rural Nevada. One of the links in that pipeline network is Coyote Springs Valley, just west of the palm-lined springs and streams at the upper end of the Moapa Valley.
Authority officials became chief defenders of the finger-length fish under a 2006 federal agreement that also cleared them to pump water at Coyote Springs."

So 900 Washingtonia filifera or California Fan Palms were cut down and the happy biologists can now snorkle to count how many Moapa Dace actually exist as seen in the photo above where palm stumps are the only visible remnants of the Fan Palm's former existence. It's the same old story, to obtain success with one's favoured agenda, justify it by claiming you just want to save something else. This happens all the time, especially regarding forestry and housing development arguments. Environmental groups do this all the time championing the life of something when something entirely different is on their mind. This doesn't mean that we shouldn't care about saving endangered organisms, we should. But you really have to put those who make claims to be outraged about an endangered creature into perspective when often times their goal is this just another "Sue and Settle" money making scheme to fill their coffers.

Anyway all these updates make for some interesting reading about California Fan Palm beyond the brief landscaping descriptions referenced in a Sunset Western Garden book. It is interesting that the native Desert California Fan Palm is on the increase in desert areas of Coachella and Imperial Valley and not necessarily by people, but by means of critters. The Mexican Fan Palm on the other hand is out of control, spreading and invading riparian habitats on the western side of the Mountains near the Pacific coast. Here are some other posts I've written regarding California Fan Palms and finally the invasive Mexican Fan Palm.
