Resource development poses a major conflict for the environment. In many cases extraction of resources does more harm than the resources are worth. In the case of the Nez Perce, the environment has been heavily stripped of its natural existence. This has impacted wildlife habitats and increased the chances of natural disasters. Of course people are not excluded from the environment, so what happens to it will ultimately be reflected through us.
Often times water can be the first noticeable area affected by resource development, but it also can be the last. Mine drainage, phosphorus released from refinery plants, nitrates from fertilizers, contamination from human waste, and construction all significantly alter water systems in and around the Nez Perce region reducing water quality for animals, plants, and humans. Along with dam construction poor water quality has severely impacted salmon populations, for it has contaminated food and redds (spawning beds created by female salmon).

Natural Habitat Destruction
Although there are many different cases of habitat destruction in the region, the following are two major cases that the Nez Perce are active conservational participants.
A century ago, nearly 16 million salmon and steelhead traveled from the Pacific to spawn throughout the Columbia River Basin - today that number has been drastically reduced to an estimated 2.5 million annually. Significantly influencing this decline have been developments such as dam constructions, which have restricted successful spawning passage. Furthermore, many species available for harvest have now been listed as endangered. Direct developmental disturbances of natural habitats, in which salmon relied on for spawning, have been the sole instigators causing declines. Heavily reliant upon salmon, the Nez Perce culture has been the main human dimension experiencing impacts of salmon declines. Aside from the Nez Perce Tribe, other terrestrial life that is reliant upon salmon for food sources have become dramatically impacted. Salmon declines are also reflected in recreational fishing - a significant source of state revenue.

Gray Wolf Habitats
Many endangered or threatened species have become so through a wide variety of factors and circumstances, however the gray wolf is one particular species of animal that humans are sole factor responsible for its decline. Up through the 1800's humans nearly eliminated the natural prey of the gray wolf (deer, buffalo, elk etc.), which led wolves to hunt expanding livestock holdings. In order to protect the livestock from being killed the gray wolf was hunted, poisoned, and trapped. When the gray wolf was poisoned the contaminated carcass was left to transmit poison to other animals such as the bald eagle. This continued as agricultural grazing expanded until the gray wolf was nearly extinct in the lower 48 states. The gray wolf was put on the endangered species list in 1967 and protected by the Endangered Species Act in 1973. Today recovery strategies have been continuing throughout Idaho, Montana, Minnesota, Wyoming, and other areas; the Nez Perce Tribe has been actively participating in these recovery strategies.
