Environmental Impacts
This case study was written by Joshua Kryston, a lower division undergraduate student who is not an earth science major, as part of the DLESE Community Services Project: Integrating Research in Education. The pages in this case study reflect the personal views of the student author and not of MSU, SERC or the NSF.

Water Quality

Often times water can be the first noticeable area affected by resource development, but it also can be the last. {1}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 {2}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.

Salmon Habitats

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. {3}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.
