To me, an "invasive species" is a species introduced into an environment where it has no natural predators. That is certainly not the case with wild horses and burros, who are subject to many predators, most especially including man. As we particularly see in this case of proposed mass eradication. This is much more than a "scientific issue."

Other than cattlemen's cattle, what species do wild horses and burros displace?

Here is one definition of "invasive species."

As per Executive Order 13112 an "invasive species" is defined as a species that is:

1) non-native (or alien) to the ecosystem under consideration and

2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health.

The feral horses and burros would displace native ruminants: bison, deer, elk, caribou, etc. etc.

The link I posted has a list of quite a few invasive species, but it is not inclusive.
