Interesting/Little Known introduced populations

[DesertRhino150]

Another species I didn't realise had an introduced population - the marine otter Lontra felina was moved to the Falkland Islands in the 1930s for their fur; there is a possibility that some still survive on the islands.

They were one of a number of animal species introduced to the Falklands by John Hamilton, a Scottish immigrant to the islands. Of these, the only other ones that have survived long-term are the Patagonian grey fox and the guanaco - the latter species had ben unsuccessfully introduced to the Falklands in 1862 but the second introduction was a success, with at least 400 living on Staats Island in 2005.

There is a paper that talks about the introduction of guanacos and mentions the other species; the abstract is included below:

I knew that they had occured in the islands but didn't know the population was introduced, I had just assumed that they were native there.

A surprising one I just found out about - Green Iguanas have been introduced to the Fijian islands.

American iguanas in Fiji - NatureFiji - MareqetiViti

The American iguana (Iguana iguana), more commonly known as the green iguana was first recorded in Fiji in the year 2000, on the island of Qamea in the Cakaudrove Province.

In 2009, they were reported from and confirmed to be present on Laucala Island, Matagi Island and Taveuni Island.

In February 2010, it was reportedly brought into Viti Levu from Taveuni/ Vanua Levu. The American iguana is native to (originally from) South America, and is reported to have been brought into Fiji by a foreign national.

Though expensive and very difficult to find, there is a relevant book that I want to recommend that pertains to introduced mammals. It is called "Introduced Mammals of the World: Their History, Distribution and Influence (Cabi Publishing)" I first discovered it in the science library on the campus of the University of California Riverside in Riverside, Riverside County, California. As I was reading it, I found some very fascinating information that I never would have expected. One noteworthy example being California ground squirrel (Otospermophilus beecheyi) being introduced into New Zealand. Again, not something I expected. They also have this book in the science library on the campus of the University of Arizona in Tucson, Pima County, Arizona.

At the San Bernardino County Museum in Redlands, San Bernardino County, California in their now defunct Mammal Hall, they had a taxidermied mount of a Gobi argali (Ovis (ammon) darwini). If memory serves me right, the species was introduced near Needles, California which is located in San Bernardino County. The population is no longer surviving. The animal in question was from a population introduced into the county. I was very shocked to see this! Prior to seeing that display, the only argali taxa I was aware of having been in US zoos were sp. nigrimontana, sp. polli, and the nominate. I probably have a photo of this Gobi argali at the SBCM. If anyone is interested in seeing it, send me a private message and I'll share it with you.

Gemsbok (Oryx gazella) in Arizona? In which localities? I know that there was an introduced population in New Mexico.

About the Pronghorn (Antilocapra americana) in Hawaii, I didn't know that they were still there. I know that they were introduced in the 1950s, but I thought they died out in the 1980s.

You're right I meant New Mexico. There aren't any in Arizona.

And about the Pronghorn: I saw on iNaturalist that Pronghorn were on the species list a couple months back, but now I just checked and it seems they were taken off. So you're right on that. I just saw them on a species list.

About the Pronghorn (Antilocapra americana) in Hawaii, I didn't know that they were still there. I know that they were introduced in the 1950s, but I thought they died out in the 1980s.

After further research the population went to 12, 30 years later, so it can be said that they are no longer there.

Florida has American Bison and King Cobras

The bison seem to be a bit of a grey area, given that they are restricted to the Paynes Prairie Preserve.

What is your evidence for King Cobras being established in Florida? The only references I find for anything connected is an escaped individual in 2015 which was recaptured soon afterwards.

I have found articles about many King Cobra sightings.

I have found articles about many King Cobra sightings.

What articles? If they are from major media outlets, I doubt they're true. Most of the people there don't know the difference between a king cobra and a garter snake.
