The evidence to support species listing comes from research published in a peer reviewed article titled “The Northern Rocky Mountain Gray Wolf Is Not Yet Recovered”. In this article they discuss how the delisting does not address the lack of genetic diversity between the Yellowstone packs and other Rocky Mountain wolves. This means that there would not be enough species available to prevent interbreed pups. The delisting is also inconsistent with how other species have been taken off the list. The delisting of the Oregon species cannot be aligned with how other packs in other environments are doing. These actions ignore how different packs respond to different environments. Another reason to support listing is that wolves have not been allowed to migrate without human intervention and should not be delisted until they are able to do so. The species needs to be able to survive and thrive on its own before being delisted. The wolves need to be able to adapt to their local ecosystem and make their own “dispersal decisions”. This will allow descendants to be properly adapted to the area and have good gene flow through generations (Bergstrom, 2009)
