Yeppers, terms do get confusing. In the plant world domesticated species that escape into the wild are called weeds, invasive, or noxious. I guess my point with this is that calling these horses "wild" indicates that they belong in the ecosystem and removing them is a bad thing. If we used the correct term of "feral" it places the discussion in the right context, that this is a non-native species that is causing damage, and how we go about managing that is the real discussion. Calling them wild and making it sound like they belong leads to an emotive conversation, rather than one about management.
