Alternate invasive species

Cane toads anywhere outside of Hawaii are going to be troublesome to say the least

Cane Toads are native to Central America, if they were native to Hawaii, they'd have killed pretty much everything by now, or left the islands a much more robust ecosystem.

Saltwater Crocodiles in South Florida. These monsters make alligators look like iguanas.

 

[mowque]

Sooner boll weevil. Big butterflies there.

 

[TapReflex]

let me think.

Here in Hawaii, Mongeese were brought over to kill rats.
that didn't work for rather Obvious reasons.

If...say Owls or something were brought instead, the Native Honey Creeper and Pu'eo/Hawaiian Owl Populations would be decimated, while the Nene Goose might be some what better off.

But atleast the mice would be under control, If that's any small consolation

And they're bigger, more vulnerable to the cold, have issues in fresh water, and thus are far Easier to Hunt in places, although they'd spread like crazy through the Gulf and Caribbean.

What if someone brought in Burrowing Owls? You'd have cars to keep them under control, and they'd eat mice like crazy, but wouldn't harm the Honey Creeper and Pu'eo populations as much. (Although they do eat nestlings and smaller birds on occasion.)

Having seen Salties well up the Ord River, and knowing that Conservation and Land Management have a team who regularly go out and trap them well over 200km from the coast, I would say that this is incorrect. That and the fact that Black fellas will not camp close to a river even when they are as far from the ocean as Halls Creek.

Raccoons and coatis are already invasive species in Europe IOTL because of the exotic pet trade -

I know raccoons are established in continental Europe, but are
there breeding populations of coatis in Europe

Also, I read somewhere that Nile Crocodile would fit nicely into the Great Plains / Southwest Desert ecosystems, especially in the warmer areas. The only problem was that by the time someone might have moved them to North America, the great herds of bison which they would have fed upon would mostly be gone.

The Nile croc would never make it in the US.The American Alligator is far more cold tolerant, and lives as far north as Oklahoma, Arkansas, and Missouri. The Caribbean croc has a foothold southernmost Florida, but cannot make headway against American gators.Why would Nile crocs fare better?

Yeah, but the fresh water here is also way too cold for them, save a couple of the lakes, and the Everglades

Parrots in larger numbers in Florida could hurt the date palms. Parrots eat dates right? Sorry, ecology isn't really my strong suit but this topic interests me since my home state (Florida) is full of invasive crap.

I wonder if monkeys would take in Florida. The food sources are here but I don't know how well a spider monkey or the like can deal with the occasional Floridian cold snap.

...Fireflies became extinct on the Gulf Coast. Junebugs became less numerous. Fire ants can kill and eat a calf. Things are more in balance now, but fireflies will never come back..

This makes me very sad to read. I grew up mostly in the South, and while I haven't been back in over 25 years, there were elements of charm to remember.

Like, say, firefiles.

This bunny cry now.

In 1898 Perth Zoo release Indian Palm Squirrels in South Perth. Fortunately the stupidity of this action was recognised reasonably early on and they haven’t spread, but the opportunity was there for another invasive feral animal.

Kookaburra’s do very well anywhere where there are small mammals, lizards, snakes and birds to eat. Originally from Eastern Australia they have been introduced and are now one of the dominant small predatory birds in Western Australia, Tasmania and New Zealand. If they can survive and prosper in Tasmania their potential range in temperate climates is extensive.

Monk Parrots eat pretty much everything, but I've personally never seen them go for Dates, or citrus. The little Fuckers do love Strawberries, Blueberries, and Loquats though.

I wonder if monkeys would take in Florida. The food sources are here but I don't know how well a spider monkey or the like can deal with the occasional Floridian cold snap.

Rhesus Monkeys do fairly well here, as do Patas and Vervet monkeys, so Spider Monkeys can probably cope.

Australian Brush Tailed Possums and Wallabys have done well in New Zealand, especially the latter- they could become problems elsewhere. Although to a large extent, I think that possums have thrived in New Zealand forests is because they those forests have low concentrations of unpalatable compounds compared to other forest species.

 

[Cook]

possums have thrived in New Zealand forests

There is zero mammalian competition.

Wallabies also survive in the countryside of England!

 

[mojojojo]

Raccoons could have become established in the UK, skunks and North American opossoms would probably do quite well in most of Europe.

This one sounds interesting. What sort of date would you reckon would be appropriate for this, or else would be the most interesting?

Probably the 1880s up to the 1920s. That's when the tech was there, the money was there, and the Science and common sense weren't. That 50-year window is when people really did release some of the really annoying invasives, and tended to throw what ever they though might stick at an environment.

That period is the most likely, but honestly it's something that could happen at any time after that date as well. Even today there is a huge trade in importing live fish from as far away as China for consumption in the US, both legitimately and on the black market, and it's a major concern for US and Canadian inland fisheries. All it really requires is that the fish in question is tasty enough for people to bother with the risks/cost of import.

Nile Perch are very tasty.

Yes there is one in Mallorca. I was dumbfounded when I found about it.

So, yeah, pretty much anywhere from the 1880s on then.
