Question
What is the actual ecological impact of growing non-indigenous species? Is it actually good for the planet to be growing mangoes, avocados, bananas, and dates in Italy where they do not naturally occur? Many of my ecologist/conservationist friends argue that it is damaging indigenous ecosystems to do so.
Key Takeaways
It’s a long-winded and contentious subject, but a good point to start is reading a book by Fred Pearce, The New Wild: Why Invasive Species Will Be Nature’s Salvation. Weeds and invasive species indicate to us that there is a problem in the local ecology, but they also show us that novel ecosystems are not a negative. We can’t have purist views in which places stay in botanical isolation. The melding and separating of ecosystems has occurred throughout time.
There have been issues on small islands because animals tend to speciate. For example, when islands with flightless birds suddenly get a predator, that’s a big problem. However, continents are usually too biodiverse and stable for this to be a huge problem. We have to have an open mind and not be swayed by sentimentality, something nature doesn’t have. It just looks for systems to become more abundant with no favorites.
For that matter, where do we start the endemic selection?

Geoff's point about speciation is well taken. For those who feel strongly about invasive species & have strong preferences for indigenous flora, when restoring ecosystems & their soils, there's no reason to my mind why you can't start off with the non-indigenous species to get the ball rolling & once everything is ticking along nicely, begin reintroduction of native species with the view to the eventual weeding out of the non natives. I'm taking my cue from what Geoff, Nadia and Co. did in Jordan, beginning with that horrendously spiny tree/palm thingamabob because nothing else would grow in such challenging conditions, but eventually getting rid of it altogether as things progressed - the pioneer species; see Geoff, I was paying attention.😁😋

@wildforestorganics7298 3 года назад

Species that are endemic to the rainforests where Geoff lives have formed trillions of interactions over millions of years. In my view, allowing a few single species like camphor laurels and privet to dominate an area stops natural succession and results in an infinitely less diverse ecosystem. There is nothing wrong with using non-endemic species if they don't have a negative affect on the diversity of the ecosystem. Many non endemic plants may have a positive effect. Also, it is easier to establish natural forests by using invasive species as biomass, but they need to be pruned consistently to allow natural succession to occur.

@przybyla420 3 года назад

Long term the invaders usually lose out to taller or longer lives native species. Here in Oregon we get hillsides of scotch broom. The timber companies hate them, but fifty years later you get a deciduous forest there full of natives. The broom likes dry hillsides with crappy soil - the result of logging. It forms a dense ground cover and birds spread native tree and shrub seeds through it. The deciduous trees do well poking up out of their leguminous groundcover. They grow up, the broom gets shaded out.

I would factor in other aspects next to biodiversity, when considering the state of ecosystems. It depends from area to area, but it’s not uncommon for natural habitats to lose a bit of biodiversity (at least on paper), if they establish a sustainable equilibrium. Overall agree with your statement, nonetheless.

@sluasidhe4898 3 года назад

Here in the West of Ireland, Rhododendron, Japanese Knotweed and Himalayan Balsam have devastated the natural under-storey, and become a virtual monoculture, with natives like the Holly struggling to compete. Loss of diversity, especially to this level, worries me. Of course, generations of human interference is at the root of this, but it is also impossible to know what the impact will be in ecological time, which is a lot longer than any of our lifetimes. Tom Wessels makes an interesting point about young, ecological interactions versus established ones and how that can go very wrong, as in the near eradication of the American Chestnut due to a fungus imported on Oriental Chestnut. Overall, I feel it is unclear what the long-term implications might be, and probably a bit soon to make any assumption. Let’s see in a millenium or so.

@pinkelephants1421 3 года назад

There's the other side of the question. Which is best? Do you import the crops mentioned in the video's question or do you wherever possible, cultivate them in suitable climates closest to the point of consumption? I'd posit that the growing of avocados, dates etc in Italy is much better than importation from halfway around the world - so long as it's done in a thoughtful manner. You would eliminate most of the greenhouse gas emissions associated with long distance importation & to a degree, it may be possible to adjust/reduce packaging frequently used to maintain freshness, especially plastics.

@ricos1497 3 года назад

I think the one part of that question is why avocado (or dates)? What is it that they bring to the culinary table that other Italian foods can't? I'm probably picking on avocado a bit here, but they are an example of a product who's demand has been created over the last 10-15 years. They became fashionable, and I'd go as far as to say that they've been elevated way beyond that which their flavour or taste deserves! They're demand was clearly (initially) created because industry discovered something with cheap labour that was abundant and it developed from there. The avocado suited a mass production, monocrop system that is favourable for large business. The question isn't whether or not you should grow avocado, but whether you are growing a diverse variety of plants and species, and aren't overlooking more logical "local" varieties to satiate an already heavily targeted market. Similarly, broadening the number of varieties of a single fruit or veg (the entire planet seems intent on growing only one species of banana, which seems exceptionally short sighted) for that additional resilience. This is especially the case if you're growing for yourself rather than to sell, as you're more likely to be willing to try different types of food than a larger market of safe consumers.

@tadblackington1676 3 года назад

I think the most useful way of approaching this topic is to think in terms of it as a function. Permaculture design doesn't need to work with a limited pallet but it does need to include indigeneous biodiversity conservation/promotion as one of the functions it aims to achieve. It is also important to have an abundant and diverse mix of native insect food plants in design because that will support an abundant and diverse mix of native plant munching insects. That will year round support an abundant and diverse mix of native insect predators will supress extreme outbreaks of plant munching pests on all plants.

@sharonagoren6751 3 года назад

Continents drift apart over a long period of time allowing wildlife to adapt. Drift wood with seeds and animals can hardly be compared to ship loads of invasive speceis answering to human trends. In my humble opinion there is room for both novel ecosystems and for actively supporting indigenous species of a location in order to support local, specializing wildlife. There should be both of these systems.

My contention is that without so many cats around the Northern Rivers Geoff, we'd see more quolls. I've never seen one, though I see wild cats all the time..

@PsychicIsaacs 3 года назад

We used to have a massive feral cat problem where we were. My son would go out into the forest with the dogs and a ging and hunt them. Now there are no feral cats here at all any more, but the quolls have moved in! Sometimes I see where they have dragged a mallee fowl carcass up into the fork of a tree, so I know they are there. No other species does this here to small prey such as mallee fowl, so if you see a mallee fowl or rabbit carcass in a tree fork, you have quolls! You'll probably never see one, as they are nocturnal and quite shy, but they breed quickly, so once you have one, you'll have a good population in no time! P. S. There are also black panthers in the forest as well, I have personally seen one, and there are rumored to be pumas as well. This is in the Northern Country of Central Victoria, near Wedderburn, Inglewood and St Arnaud. This would be perfect puma/panther habitat, and the abundant kangaroo and swamp wallaby population should keep them well fed. Pumas and panthers will also drag their prey up into tree forks, so if you see a kanga rotting in a tree, you have pumas and/or panthers, and it ain't a quoll! Thylacines don't do this, although they are rumored to be out there as well, alongside the big cats.

Birds migrate thousands of miles, transporting life in both directions. "Native" identification always relies on an arbitrarily chosen snapshot in time and declaring that moment is the baseline. But as you said, the constant is change.

@tim1tim2tim3tim4 3 года назад

Yes the constant is change but maybe we should ask: is the a limit in the speed of changes? With the strong climate change and anyway introduced species there is already a really high pressure on the ecosystems to change. If we further increase the pressure could it lead to more extinctions than creations of species?

@jameshunt2905 3 года назад

....and isn’t one aspect of recognizing change in the different cycles of change, how they interact and the timing in which they are observed, by whom and from what perspective....... this is where for instance mathematics embraces complexity and different levels of perspective in its expression of said complexity that also embraces this very insight of diversity and how when different factors are considered and in turn are understood differently. An example verbally expressed might look like “diversity” is the recognition of the multitude of elements or factors in a given “environment.... this element of “complexity” might offer the recognition of what the spaces between what is recognized as “diversity” and how that idea would factor into the whole of an ecosystem as it relates to others and self regulates “over time”....... the “rabbit hole” reveals itself about...... HERE... (grin)

@MrMadalien 2 года назад

Well, I get your point but it's in fact not arbitrary. Because the introduction of alien species destabilizes the local ecosystem and makes it less favorable for humans and all other animals that depended on that steady state that exists without alien species. A balance needs to be struck between new and old, too much new can tip things over the edge and make a difficult recovery. It's just like climate change. The idea of climate changing is not really interesting, it is arbitrary too because of course the climate is always changing and always will change. But in our language, we use climate change to describe actually the impact of a quickly shifting climate on human industry and society. Without humanity, the use of labels like climate change, native vs alien, soil erosion, etc. is all arbitrary and useless, as it all begins with impact on humanity and similar animals. Does that make sense?

Fred Pearce’s contention (in the book that Geoff references in the video) is that it is generally not the invasive species that decimate native ecologies, rather it is human disturbance that damages the native ecology to the point only one specialised species, usually an exotic, can thrive in that environment, it is then this one hardy species that gets blamed for the damage caused by industry or monoculture-farming. In fact, if you wait long enough then it will transpire that those hated invasives actually rehabilitate the land that was so damaged by humans.

@tim1tim2tim3tim4 3 года назад

Thank you for pointing this out! One thing to add: saying that planting avocado trees is better than nativ crop trees in Italy is not the best example. Usually when you think about this question you have a monoculture of this specie. In that case a monoculture of avocado or a native tree doesn't change much to the habitat that native animals have. Monocultures are always bad. But in our case of permaculture we have diversity. In this case its fine to add some non native trees if there are already some native ones. If there is a good amount of native plants the environment can adapt easily.

As Bill Mollison said, we are all native to Earth. But he also said that we have a responsibility to conservation, so we don't lose diversity. Palm oil plantation monocultures in the rainforest is disaterous to species diversity, and snubs the "care of earth" ethic of permaculture. So I would argue that any time a "non-native" species harms species diversity, or creates a monoculture, that is when we should reign things in. We have a responsibility to preserve species, aka care of earth. Reality is, if humans want to keep living in Australia, we have to eat non-native foods. The native crops that kept the aboriginals alive are largely extinct now because of white man, so it would be difficult to maintain a balanced diet on native foods. Especially in southern Australia. I would also argue that aboriginals brought crops with them wherever they travelled (such as when the land masses were connected, or closer together). So the native plants that native Australians grew might not have all been "native", in the strictest sense of the word. It comes down to where you draw your arbitrary line. As with all things in Permaculture, it's about balance, and ethical practice.

I grow Opuntia ficus indica on my farm. The soil beneath my prickly pear plants is richer and darker than the surrounding soil. Even more "wild type" prickly pear species such as wheel cacti and beaver tails have this effect. Grass grows greener and more abundantly underneath these plants. I have heard of farmers shredding prickly pear pads and putting them down fruit tree holes before planting a fruit tree there, and they are also an excellent "guardian species" for newly planted fruit trees as well. Everything behaves more carefully around them, except that goats love them and will demolish them in short order and horses and other livestock will eat the young pads. This is an example of how an "invasive species" can be a useful member of the ecological community. My suggestion for anyone out there who has a massive Opuntia "problem" on their land is to become a goat farmer. Within a few years, you'll have fewer or no prickly pears and the most beautiful fertile soil that you could possibly imagine! Either that or farm cochineal beetles. You'd be surprised at the price that these bugs fetch on the open market...

@davidakerlund3551 3 года назад

i disagree with this. invasives often lead to monocrop/monospecies in where something like goldfish outdo and kill every species in a lake because some idiot released them after not understanding how too care for them if humans create a problem its humans responsibility to fix it

@erfan4244 3 года назад

He said non-indigenous, not invasive. Also even invasive ones could lead to more diversity if provided enough land as opposed to small highly sensitive islands according to him.

@xiaox3293 3 года назад

I did hear him mention invasive, I think he mistook invasive species for introduced species. Invasive = introduced AND harmful.

@acobster Год назад

This is some great food for thought but I didn't hear him address the issue of invasive species driving down overall biodiversity. For example, I live in the PNW where English ivy and Himalayan blackberry are everywhere. They overtake entire hillsides at which point it seems like nothing else can grow there, native or not. What are we supposed to do in that scenario?

@PaleGhost69 3 года назад

We're all native to Earth. When that is no longer true, I'll start worrying.

@kiri101 2 года назад

I speculate that the rapid speciation observed in some of the finches which Darwin formerly studied is in some way due to genetic memory/the 'junk' DNA which can store old copies or fragments of genes in our evolutionary history. If so then preserving genetic diversity is an important goal itself to ensure rapid speciation and protecting native species who are particularly vulnerable is important. Overall you're correct though, the baseline for 'native' is rather arbitrary.

@NashvilleMonkey1000 3 года назад

My favorite quote of yours is "we as a species can be as good for the planet as we have been bad for it" or something to that effect. I mention that first because I'll now point out that Humans are the number one non-indiginous species, and we need to take with us the food plants that we thrive on. It doesn't get any simpler than that. Come to think of it, we are all native to planet earth, so it's all good~

@NashvilleMonkey1000 3 года назад

Oh good, you said it at the end even~ i'm wrestling with the fact that heirlooms are completely inbred plants, and hybrids are crosses of inbred plants, and that any move towards resilience from diversity is unceremoniously shot down by what is commonly taught to gardeners. There are a few who understand, and I didn't know how bad it has gotten until now, that it's an extreme crisis in the biodiversity of every species that humans cultivate. (and I personally take the step forward to create this much needed diversity, even if I'm not in much of a position to do so, it must be done to save the planet).

@kikikut22 3 года назад

Yeah man, as interesting, easy, and hopeful as he makes it sound by just countering our human activities that are causing extinction by instead putting our efforts toward a God-like speciation set of actions. True we CAN have positive impacts on our environment if there's the willingness, but I think this theme of extinction and speciation has MORE in common with the concept of entropy (Most of the time it's much easier to destroy than create order)

i would love to hear geoff's opinion on the situation in hawaii. we're having so many of our native species go extinct because of the constant importation of invasives. the situation is quite dire, and we would loose so many of our native species if we didnt intervene at all. ive seen single plant species out compete entire native forests when left unchecked, including plenty of endangered species. mosquitoes, cats, dogs, and rats are killing many of our native birds. invasive amphibians and reptiles are killing off our native insects.

@car6120 2 года назад

How does permaculture encourage speciation ? Extinction can happen in a blink of an eye compared to typical speciation even in organisms with small generation periods e.g. finches. This is a very dangerous sentiment to ignore all conservation efforts entirely purely for maximum productivity using foreign biodiversity and restoration. One of the best and necessary ways we can can maintain genetic diversity is to protect what we already have. Good points here but please dont walk away thinking you can let all your invasive animals and plants rip through your local environments unchecked. Tread carefully.

I've head you mention that book before, and I need to actually pick up a copy. All of Fred's books, by the sound of it. This is a really succinct explanation of a conversation that I've tried to have a number of times. If species are becoming a problem, it's are a human-caused problem, or only a problem for humans. When we take a broader view, we can often find solutions to use those species in a productive way, or else a solution for removing that species in a more holistic way, if it proves necessary.
