Invasive Tree Rescues Arizona Town!

[@Reciprocity_Soils]

Hello, Jerome! As the Tree of Heaven serves its purpose, cut them down and use them as organic matter to regenerate the soil. Eventually, with aggressive maintenance, it's feasible to replace more and more of these invasive trees with native trees, bushes, and grasses. Such an interesting story. Thanks for sharing.

[@betespatiotemporelle]

Cooperative systems eventually win, after a crisis.

[@ConsciousEntrepeneur]

Thanks for sharing, I concur with your thoughts. Multiple eco-restoration systems and more education to general public, can have great impact.

[@BryceGarling]

As long as you're financing that project and hiring the labor you might have a good idea. Last I heard there are hundreds of thousands of biologically degraded ecosystems from that tree for you to get started on.

[@DIEGhostfish]

Probably better off removing Tree of Heaven from all the other places its wrecking before turning our attention to the ONE place it's doing something good.

[@keenanheart3304]

The tree is really good at destroying the infrastructure of buildings and is responsible for a heap of problems that cost the town a whole heap of money. My (step??) uncle used to be the mayor of Jerome and I lived there for around 4 years. That tree can be dangerous for a lot of reasons. Don't ever try to climb one, for instance, as it is not very strong and the largest of branches will just break off like basal wood. The tree solved issues but was also one of the reasons the whole town burnt down 4 or 5 times over. They grow so fast and spread so fast they can create an incredible amount of fuel for fires in a very short amount of time. I miss Jerome sometimes. It is a really fun slice of the west and anyone with the means should strive to visit. It is truly unique.

[@renaissancewomanfarm9175]

How cool would it be to take all those dead trees and throw them in that discard pit from the mine? Then collect the yard and kitchen waste from the town and chuck that in there as well. Occasionally throw in some activated char and build the largest terra preta site in the state. Imagine that extending from that area and all the trees that are beneficial that could then be planted. Wouldn't it just be fun to try?

All the spotted lanternfly in the area go to that tree above all else, and they all die. As an organic gardener who moved from a SLF impacted area to a place where it hasn't reached, yet, I intend to use the bait tree method when they get here. They're such a devastating pest, I'll poison one tree so I don't have to poison my whole garden.

@@got2kittys - Jerome is not desert. They average 18-25 inches of precipitation depending on the elevation. The original vegetation was grassland and dense chaparral at the lower elevations of the town, intergrading into juniper and pinyon and ponderosa pines higher up on Cleopatra Hill. Some of the causes of the current sparseness of the vegetation are explained in the video. In addition, almost all of the sizeable trees in the near vicinity were cut down for mining timbers and firewood. This combined denuding of the vegetation resulted in much of the topsoil being washed away. It will take centuries for some of the areas to come back.

If not for Lupine, Iceland would have become like the Sahara only in the north due to wind and deforestation! Considering that this is a ground cover plant and a nitrogen fixer, and the external appearance is magnificent, honey plant! - I think this is a great solution - this plant structures and prepares the ground for shrubs and trees, there are types of lupine with a low alkaloid content suitable for livestock feed! It is on the same principle that I feel very good about paulownia - although some environmentalists are very aggressive towards this tree! For example, compare Ailanthus altissima the highest and Paulownia - he has only minis in front of Paulownia! However, biodiversity helps grow forest plantations even better and more efficiently and more resiliently!

[@diseasedleginc.6528]

This tree does the opposite of providing a substrate for native vegetation. Tree of hell possesses negative allelopathic traits which prevent the germination of native plants by exuding chemicals into the soil through their far spreading roots. The chemicals produced during the decomposition of the trees leaf litter also prevent native seed germination. This tree suffocates and destroys all native plant communities, do not try to use it thinking that it will enable ecological succession because it will result in widespread ecological recession.

[@jherman89]

@@diseasedleginc.6528If it's pruned continuously and soil organic matter builds up, what happens to the allelopathic chemicals in the soils? Do the chemicals breakdown?

I would be curious to know if there are exceptions.

[@MrChristianDT]

I think the chemicals break down pretty quickly & the trees do produce a lot of dead fall that technically makes the soil very rich, but I have yet to find native plants that sprout well under them. The chemicals come from the roots, though & two things you can do to get around it is putting thick rock barriers between the tree & where you want to plant other stuff, then keeping an eye on the seedlings to manage the tree of Heaven populations & also you can put in live plants instead of seeds & they will settle in & do fine. The chemicals only seem to affect seeds themselves.

If you're having trouble with Ailanthus, use Tordon. It's a brush killer. Simply ring the bark of the main trunk, apply liberally to the cut, and wait for the the tree to die. Ailanthus are tough trees, but one or two applications is usually all it takes, even for mature trees. Before you remove all of them from your property though, try potting a few seedlings in some tubs and take advantage of their ornamental properties. They grow quickly (20 ft in a season, easily) and can take on a lovely palm-like appearance; especially in small groups. Then coppice them back every year or two and they'll pop up again the next year.

I have this in our farm. Without a lot of active labour, it's not possible to get rid of it. We moved here 3 years ago, with only a few trees like this, but the amount of sprouts from the old trees and also the seeds they produced makes us a lot of work every fall and also in the spring, we are walking around pulling new sprouts. Not only that, it's actually preventing other species to germinate, because their roots produce a poison for other plants. Not a good idea. It's a barren land currently, with the occasional small trees popping up and a few blades of grass. Nothing else would grow in those areas yet. Maybe after a few years of work, the roots will weaken enough to die. And it's a lot of work. No animal goes near it, even our pigs don't disturb the root. Not even a bird would rest on the branches. Apple saplings we bought: died in a few months of spring. Oak: they are smaller than when they were planted. Alfalfa: did not even germinate.

I’ve seen Ailanthus take over hillsides in various places, though I suspect it wasn’t usually brought in on purpose. I recall a big chunk of Boulder, Colorado claimed by it. In my native Decatur, Illinois, not especially prone to erosion, there are some huge ones in the older parts of town, and small ones show up everywhere from seed or roots. I’ve seen leafy stems of it used outside University of Illinois fraternities to give a vaguely exotic touch to tropical-themed parties. It’s also the tree that grew in Brooklyn back when NYC was full of heavily-polluting industries, used as a metaphor in the famous book.

The downside is what do you do with the site afterwards? Some invasive (such as this) will release chemicals that inhibit the growth of other plants and decrease biodiversity. to It would be better to use pioneer species that are appropriate to an area as far as addressing food, soil stabilization, etc. Think soil biota degradation plays a part in how invasive a plant is. You'd have to have a bunch of control zones to compare.

ANDREW --Lots of people watched this video and have no idea about the downsides of deliberately planting invasives and are bragging about their introduction of this or other invasive species on their property and elsewhere. You need to do a follow up to stop the cascade of harm. You mentioned 'outcompete' which implies faster, more vigorous growth but fails to mention A. altimissima's allelopathic nature. You can still plant many non native plants and they'll be okay. It is also okay to consider planting 'plants labeled as invasive' by your local extension service* but do research first. Having the Ailanthus altissima establish in the mine talings was super. Fortunately the site also seems to make the spread of ailanthus self limiting due to water constraints (the town roofs providing the needed extra water so that it can survive. This tree can be used in phytoremediation of nickel and lead, wonder what was mined... When were they introduced? Ailanthus is allelopathic. It is hoped a derivative can made from it to inhibit algae blooms in lakes. Wonder if the mayor knew it's reputation for being stinky? Wonder what they could have planted instead that would have been combative with the talings? Did the town population rebound much? *Our local extension service overreacts and has labeled non-invasives as such on the assumption of guilty until proven innocent. Now we have chemical 'experts' idiotically spraying at the river.

Possible downsides of A altissima is that it significantly alters soil biota: effect of varying A. altissima densities in a forest of north-eastern France on soil microbial activity, diversity of various litter and soil invertebrate groups (Arthropoda, Lumbricidae, Gastropoda), diversity of functional groups (predatory, detritivorous, coprophagous, phytophagous), and trophic structure. Our study shows that increasing density of A. altissima is associated to lower soil microbial activity, decreasing abundance of litter detritivores (Acari and Collembola) and aboveground predatory Coleoptera, and decreasing species richness of terrestrial Gastropoda. In contrast, increased A. altissima density corresponded with greater abundances of litter Lumbricidae and aboveground coprophagous Coleoptera. We found an overall impact of A. altissima invasion on the soil food web structure that could accelerate the mineralization of organic matter and potentially favor nitrophilous plant species in understory plant communities.

Great to hear how the "pest tree" has stabilised the landscape and prevented erosion for the time being. Of course any number of drought and hard soil tolerant trees/shrubs could have done that. I'm thinking of Australian "wattles" (ie various Acacia species) almost all of Australia's which are thornless, and which have foliage and seeds edible to animals like birds, chooks and sheep etc. However the SW areas of the USA have their own distant cousins to Australia's Acacias which you call "Mesquite" (I understand many of them have vicious thorns). Australia also have native Casuarina/Allocasuarina, known as She-okes or She-oaks, which have the appearance of a small pine tree (unrelated), and which ultimately give a good quality timber, ("almost as good as oak" hence the name). Their fine seeds disperse naturally by wind and grow in poor or rocky soils and there are varieties that go from waterlogged swamp to desert. Like the acacias there are varieties which tolerate some level of frosts and freezing temperatures in Winter. So there's another bunch of Australian trees which would be less problematic and more productive, than "Tree of Heaven"

[@1amarsandhu]

Can they survive acid polluted soils though?

[@KiwiCatherineJemma]

@@1amarsandhu That's a good question Amar ! Certainly "some" of the Australian native Acacia and Casuarina species can withstand acid soils and certain pollutants. And if the correct species can be found, one without spines, which is less of a "pest" around the town, then it could be an option for them, Where I used to live in Australia, during the Summer half of the year, bare patches of soil glistened in the Sun, as naturally occurring mineral salt crystals (NOT nice "Sodium Chloride" sea salt the normal table salt) would move up through the soil profile from underground, by the "wicking" action of the hot Sun shining on bare soil. Some plants can tolerate a much wider range of soil ph, acidity and alkalinity than others, and also any pollutants that might be in that particular area. Even textbooks have their limitations. Sometimes you just have to plant a range of species which are possible contenders and see which ones work best in your areas. Where I lived had a very dry Summer half of the year and over two thirds of what rain we got fell in the Winter half of the year. My understanding is that some parts of Arizona may well have the same ANNUAL AVERAGE rain as I had, but they have a drier Winter half, and when rain does come in Summer it comes as huge sudden floods. Plants obviously have different ways of dealing with widely varying rainfall patterns. Thanks for your interest. Maybe one day I'll get a chance to visit this town for myself. cheers

There are still tons of female trees😮 which drop almost as many seeds in the fall and through the winter. Most germinate and rapidly grow, but most females seem to die after 30 or so years.

[@vociferonheraldofthewinter2284]

Exactly. I live in southeast Arizona and my land is covered in invasive species. I'm in the process of waging a war on two fronts. First weaken and (when possible) kill the invasive plants while simultaneously planting fast growing, aggressive native species. So far I've partially reclaimed one acre, but I've learned a lot and that process is going to start moving faster. One issue I have is that I have nothing but invasive trees where I have trees. They need to go, but I can't just cut them down. They're serving the purpose of trees here and we need them to help with erosion, to act as a windbreak, and as a place of shelter for native wildlife. But I can't plant healthy native trees until the invasive ones are gone. The invasive trees are allelopathic. They chemically prevent other trees from growing on this land. As long as they're here, I can't put in good trees. Right now I'm hoping to find a shrub that is capable of competing with the tree and maybe then I can begin the transition. Invasive plants are 'invasive' for a reason. It's not just that they grow well and out compete native plants, it's that they actively harm native plants and prevent them from reestablishing. Sadly, there's a lot we don't know about their chemical warfare. What's the distance from the tree that the chemical do it's work? How long does it last in the soil? Is the chemical carried away by ground water so that the soil is contaminated downstream? We don't know any of that.

[@jherman89]

@@vociferonheraldofthewinter2284 Have you tried heavy pruning or coppicing of the invasive trees and then planting native vegetation or even cover crops? Repeated pruning/chop and drop could build the soil gradually and provide better conditions for native species. A reason that invasives are present is often because of disturbance. Previous disturbance (e.g., deforestation, overgrazing) would have led to erosion and soil loss and these poor conditions may have favored your invasive trees. From this perspective, the invasive could be seen as a pioneer that's doing the work of improving the soil and environment for the next stage of succession.

In New York City, where I lived in the mid 1970s, Ailanthus began dying out from a Fusarium oxysporum outbreak ca.1978. I had been rearing Cynthia Moth (Samia cynthia) caterpillars through successive years on leaves I collected from Ailanthus trees I passed by when returning home from work, and in that year, many declined and died. What was apparently another strain of F. oxysporum (forma perniciosum) had wiped out most of the Albizia trees in the city and suburbs during the 1960s and early 1970s. (In the latitude of NYC, seedling winter survivorship of A. julibrissin is too poor for the tree to become invasive, and they were much admired and widely planted ornamentals.) Our 'news' media did not note the sudden death and subsequent disappearance of most of NYC's Ailanthus trees until the 1980s, years after this was evident to even casual observers. Both A. julibrissin and A. altissima happen to be among my favorite trees from childhood! The Ailanthus thrives mightily in disturbed and anthropogenic habitats such as heavily urbanized environments, gravel railway embankments, vacant lots, etc., but competes poorly with both native and introduced trees and shrubs in more natural environments. As the Fusarium outbreak made evident, A. altissima is not indestructible. It does not tolerate extremely cold winters, and is intolerant of shade as well. While the foliage is rank when crushed (instant karma for people who unthinkingly and impulsively break foliage off of trees that they pass!), and the flowers (which are visited by many native insects) have an odor that is reminiscent of fermenting melon rinds, it is an attractive tree when not badly crowded by suckers and seedlings, and the bright chartreuse to light green immature samaras, tinted or highlighted with anthocyanins ranging from salmon to red and purple, are very beautiful. NYC still has isolated Ailanthus trees, but most seedlings are killed by Fusarium after they attain a few feet in height. Individual trees isolated by expanses of blacktop seem to be protected against Fusarium; some have continued to thrive and set seed decades after nearby specimens unprotected by blacktop have died. The city's once extensive monocultures of Ailanthus in vacant lots, railroad yards, etc., have been almost entirely replaced by (ugly) monocultures of Mugwort (Artemisia vulgaris).

Sounds like a ton of maintenance for a tree species. You might be right, but it's probably not worth the time unless you have a way to recoup costs associated with the maintenance. I think you'd be better suited to acquire biomass from mostly outside sources, do the biomass creation off of a single cull of the area as you described, and then hope that native species can win out in that localized environment before the next set of trees grows in and shades it all to death and then proceeds to regress soil composition. A cyclical thing but potentially possible to claim back soil biota and space bit by bit. Invasive species, whether there are any temporary positive effects or not, have significant negative impacts and externalities which in the end earn them their name of invasive.
