That's bloody awesome Jack. Such a cool idea and the detail you put into it is amazing. I find it very satisfying being able to provide such enrichment for animals. Brilliant content
Nice, it's always good to keep outdoors. I would say though there are plenty of US species that do great in our climate also. When you mention European climate being like ours, you have to remember that the climate in continental Europe is much more stable than ours due to the continental effect much like the US. They both have harsh winters and dry hot summers. We have wishy washy mild weather most of the time, with lots of rain so it's important to use species that can cope with that. I keep spotted turtles outside, those guys are very at home in mild weather and actually prefer temps in the 15 to 18c mark for activity. I would have most definitely extended the liner for the ponds way past the edge and buried it in the substrate. The last thing you want is anything getting stuck underneath there! Great to see you are moving things outside though. I still have snakes inside that are tropical but since keeping outside I always feel guilty about that lol.
There aren't any feral populations of the species mentioned in your video because they are not domesticated species. They are all wild animals whether they live in captivity or the wild, and regardless of whether they are tame or not. You can't make a feral animal without first selectively breeding a wild species into a brand new domesticated species, then letting that domesticated species get back into the wild.
