Honorary mention: Dandelions. When America was colonized the seeds of many crops were brought over and among them were the seeds of weeds including dandelions. However dandelions aren't considered invasive because they have assimilated almost flawlessly into the American landscape and even provide nutrition for herbivores without any downsides as they don't take resources away from native plants.

The term "invasive" only really applies to those that have actually had a very negative impact on native species and the ecosystem. If it's not that impactful, it's simply referred to as a "foreign" or "introduced" species like the ones mentioned here that have become beneficial

@@speedbump9299 you're half right with Brown Anoles as yes they have become somewhat naturalized. there's actually a lot of studies done on Brown Anoles and their impact and South Florida, which I live in, has a very particular situation. What they've found is that while there are cases of Brown and Green Anoles coexisting on various Caribbean islands usually after a period of Brown Anole dominance over a particular niche elevation, the Florida native Anolis carolinensis (native green anole) has been outcompeted out of a good portion of their range. The bounce back of Green Anoles in those regions correlated to the introduction of another green anole species: Anolis porcatus (the Cuban Green anole). The native green anoles and the foreign green have actually hybridized and in turn been able to retain lost portions of their territory, although they are still restricted to higher elevations in the trees while the Cuban Brown anoles control the base. The naturalization may have been from the influence of a species that already had to deal with the Brown Anolea in their native Cuban range. But yes, there are many predators that also regulate their numbers as well

A few others: Domesticated Rock Doves (pigeons) were introduced to North America in the 1600's. They very quickly established feral populations and are now a large part of most urban biomasses. But they're much less common outside urban areas. Large buildings are just as nest-friendly and less predated than natural cliff faces, and it turns out the pigeons, despite being larger, are actually outcompeted by native dove species in the wild. So they follow humans from city to city. They - along with rodents like mice and rats - make up the bottom of the urban ecosystems; rock doves have in fact been absolutely essential to the survival and recovery of small predatory birds such as falcons and some hawks. Feral horses are much like the Eurasian beaver; an endemic but locally-extinct species in the Americas. They were reintroduced in the 1500's (accidentally, of course) and quickly made themselves at home, despite persecution from humans both for re-domestication and to get them off pasture land. The land the horses favor did quite well with them on it since it's an ecosystem that evolved to have horses as part of it. Unfortunately due to that persecution, American horses have bene pushed to more marginal desert land, which is less suited to them and more fragile, making htem something of a problem there. Zebra Mussels, despite often being included as "worst invasives" are actually quite good, ecologically; their bad rep comes from the burden they place on industrial infrastructure, rather than their ecological impact. Much as with the horse, they are a functional replacement for locally extinct animals; lake Erie's native mussels and clams were largely rendered extinct by pollution, well before the hardier zebra got introduced. it has had a significant effect at cleaning the lake's water, creating habitats for fish fry, crustaceans, and gastropods, and serves as a food source for the previously endangered smallmouth bass and lake sturgeon, as well as migrating waterfowl.

Just posted about this too as I didn't notice your reply yet. The story about their introduction is also amazing: during the height of Pablo Escobar's drug empire, he built his own zoo, for which he imported African animals like giraffes, zebras and hippos (four of which were smuggled from the US). When his empire collapsed, the zoo was cleared by authorities but for some reason the hippos were left behind, assuming that they would just die. Somehow, the hippos made it out into the Amazon rainforest where they multiply like rabbits. Every now and then, small Colombian villages are suddenly overrun by a herd of hippos looking for food. Some scientists and environmentalists have called for programmes to kill or castrate the hippos as they have some damaging effects on the environment including polluting waterways due to hippo poo. However, killing is opposed by local residents who love the hippos, which have become a symbol of the area and a tourist attraction. Meanwhile, castration is nearly impossible because both male and female hippos have internal gonads.

Huh. I'd always thought the Escobar hippos were a real problem for the Amazon. Though then again, maybe they're just a nuisance to humans rather than the ecosystem itself? I've heard it's a bit of a puzzle whether introduced species that appear to be reverting ecosystems to pre-human conditions is a positive thing or not - such as introduced earthworms possibly starting to bring back the mammoth steppes of old in North America - perhaps the ecosystem would have been like that all the while if humans hadn't showed up, but then again, anything that has adapted to live in what the place has become post human settlement is probably going to suffer from this reintroduction (anything that thrives in a temperate rainforest isn't going to appreciate them being turned to plains by earthworms). I guess it's not perfectly cut-and-dried what the values of a conservationist ought to be.

I feel like the kudzu bug is also worth mentioning. As you can tell from its namesake, its host plant is the insanely invasive kudzu, which it is specially adapted to feeding on, it's probably one of the few things able to keep that plant in check, severely weakening its health long enough for other plants to have a fighting chance. What makes them so great at it is that the nymphs can only survive on a few legume species, their favorite being kudzu, so they usually stay around the kudzu infestation as much as possible, and won't leave unless their food completely dies off. Unfortunately, the adults feed on any other legume in its vicinity, especially if the kudzu dies out, and most other legumes can't handle its aggressive feeding, soybeans are hit particularly badly because they, along with kudzu, are the only plants kudzu bugs will lay eggs on, which means that while other legumes just have to wait for the adults to die out, soybean will be used to replenish the kudzu bug population, targeted nonstop until barely any is left. Plus, they invade houses during winter. People genuinely see it as a double edged sword due to its effectiveness in beating down kudzu, but it also just destroys soy.

@@annak804 planting soy away from kudzu isn't always enough to help. Remember, I said that kudzu bugs have two host plants, both soy and kudzu. Planting any other legume away from those host plants would work, but they will actively seek out both soy and kudzu, and will use both for reproduction. Your best bet is to just not grow soy within several hundred miles of the nearest kudzu patch, assuming there's no other legumes inbetween the two locations for the bugs to "island hop" from, as they will wander pretty far when things get too crowded, and storm winds can carry them even farther. They don't even need the kudzu if the local soy population is big enough. Personally I don't care much for each crop regardless of the resources they provide so I'm fine with a bit of collateral damage if it isn't completely ruining someone's life. Honestly it probably hurts monoculture soy plots more than anyone else, and if you practice monoculture, you're sort of asking for it.

1. 2. 3. I would be careful with endorsing the idea that their presence is great. At the end of the day, invasive species are the greatest contributors of extinction after habitat destruction. The peacock bass could risk spreading if climate change keeps up. As for Tamarix, while it provides a nest for an endangered flycatcher, it degrades native wildlife habitat due to effects like soil salinization and water consumption when in large numbers. The real issue is we need to reintroduce the native trees the flycatcher uses and not interfere in nesting season. As for the green shore crab, I think a better solution would be to bring back the native predators and start developing a taste for green crab. 4. 5. The tortoises I can understand, after all, while the tortoises on the other islands went extinct, their closest relatives phylogenetically are those tortoises, and the plants needed them. The beavers don't count, Eurasian beavers were present in the UK before their extirpation, they were just a reintroduced species. I say all of this as someone who spent the better part of 6 months eradicating invasive species.

It was an accidental introduction however through the discharge of contaminated cargo ship ballast water. While it has killed tens of thousands of birds in the Great Lakes region, zebra mussels are pretty efficient at filtering water, they can accumulate tons of pollutants and toxins. This has resulted in a decrease in pollution levels of the lakes. So while still invasive and deadly, they do at least have one positive aspect. The dingo would also fit on this list.

Admittedly, the zebra mussels have improved water clarity, and that is a benefit, and some native species have learned to feed on them, such as canvasback ducks.

Sometimes an invasive species can get itself so wedged into an ecosystem that it completely supplants a role and becomes dangerous just to remove without careful consideration how to do it. It becomes akin to a knife lodged deep in the body: ideally it wouldn't be there in the first place, but once there it can no longer be simply ripped out without immense caution and preparation. For example, feral cats on a certain island were eating the local endangered songbirds, but once removed the rats overpopulated and ate their eggs anyway. Maybe a video on this lesser known phenomenon? Just because a species is invasive doesn't necessarily mean the problems stop once they are removed.

Normally when I used to work on a fish farm off the coast of Singapore when we go fishing during our off hours we normally or always manage to catch groupers or occasionally a stingray. Rarely have seen those butterfly peacock bass. But maybe they are mostly in other parts of Singapore. Pretty interesting knowledge to learn. Good thing to KZitem recommending this kinda vids to me.

Another technically invasive species that is worth mentioning is the Joro spider. Last year they were everywhere in the southeast US having hitched a ride here from asia at some point. The good news is that as far as researchers can tell they aren't displacing native species like orbweavers and they are a natural predator of the brown marmorated stink bug (another invasive species), which is a huge pest in this region.

As far as successful re-introductions of species it brings to mind the re-introduction of wolves to Yellowstone. The re-introduction has had very positive effects on the habitats within the park as grazing animals have changed their grazing habits and allowed trees to reestablish themselves in places that had been overgrazed for decades.

In michigan they had a flyer about how to trap/purge/eat then invasive rusty crayfish. They are in our rivers and lakes by the thousands. We did it a few times but geez to get a meals worth took a few days. Their tail meat tastes just like the bigger red crawfish from down south but its a lot smaller in size compared to the body/claws. Plus you have to be very careful where you harvest but technically that can be said of all harvesting of fish/crayfish We put them in a kiddy pool with the trickling hose and a can of sweetcorn lol It was a tip from a friends mom who lives down south and has crawfish boils. Helps them purge the nasty bits lol. But the looks on faces when you tell people you're crayfish trapping for dinner. Lol. Its just not really done around here. Plus you need a fishing license. If they made eating the invasive crayfish free/no license I bet more might do it.

I think we should bring the aldabra tortoises to mauritius. Because without the dodos on that island. No one is there to spread the tree seeds for the plants. And as you said. The tortoises were pretty good at their job. So since mauritius/dodo island is declining in plant diversity I think it wouldnt be too bad of an idea to introduce the tortoises there either considering the fact that the island they were introduced on previously was very close to mauritius and has similar flaura.

Re-introducing a locally extinct species (or a related one that will fill the empty niche) will usually have a positive effect. Especially in Europe where several once prominent species have been hunted to extinction, with humans artificially trying to keep the balance in their absence (like hunting quotas for browsing herbivores in the absence of large predators). The vacant niches cause a vacuum that affects any species adapted to their existence, causing a ripple effect throughout the entire ecosystem. Reintroduction is basically patching a hole and hoping the seams haven't unraveled too much for it to hold. Of course they can cause other issues unrelated to their role in the ecosystem - like wolves and lynxes also going after livestock - so it's rarely done with larger animals...

The problem with that is that modern elephants are grazers like mammoths and mastodons were mostly forest dwelling browsers. African Forest elephants would be closer to mastodons, but their bodies don't adapt to cold very well. Asian elephants are closest to mammoths genetically, but still would have a hard time adapting to the colder climate of North America.

We used to have ringneck pheasant in my area of michigan but you rarely see them now.. we get the occasional quail because i live about 12 miles from a big state park that has dog/horse game trials. They release lots of different quail into the park for these trials. The bobwhites are quite interesting to run across while hiking the trails there. Now bobwhite quail is native in michigan but not this far up. We usually get too harsh a winter for them to survive.

When an invasive species is introduced to an ecosystem, it kind of like soft reset the ecosystem to a extent. They kill the other animals in the system, to the point only the ones that adapted or have better chances survive. Eventually the remaining animals would evolve along side what was once invasive and now creates a new ecosystem and native species in a sense. Just at first has to take our other competitors for that niche to change the system. Such as the invasive tree being bad for the plants but being used by native birds that’ll grow along side it if they choose that tree species over others. Just an interesting thought I had while watching. Enjoyed the video ^ Edit: this thought came after I had finished, if you think about it. Humans are the biggest invasive species overall, especially early on when we didn’t know animals could go extinct.

I think the bigger problem with cordgrass is common reed which has pushed it out in many areas with human disturbance. This can only really happen with human disturbance. When there was more cordgrass, the purple crabs were likely not a problem. I don't know how good it is that their numbers are much reduced. I have seen native cordgrass, and I've seen native mud-living crabs, but never those purple crabs.
