The Mexican wolf is one of the most endangered animals in North America. The decline in Mexican wolf population has numerous causes, including targeted killing, disease and genetic problems. By their very design traps are inherently cruel and indiscriminate and pose serious risk to wildlife including threatened and endangered species. This ban although temporary, will go far in protecting the Mexican Grey wolf and will hopefully lead to a permanent trapping ban in wolf territory.
