Central Idaho threatened/endangered fish habitat is threatened by public land livestock grazing. Federal managers drag their feet. WWP threatens to file suit.
Many folk don’t realize the impact to native fisheries habitat that livestock grazing can and does have. The Forest Service, Bureau of Land Management and other land and wildlife management agencies work diligently to avoid acknowledging livestock’s impact to listed fish species such as Bull Trout, Chinook salmon, steelhead, and Sockeye salmon even when their own biologists and other scientists officially describe the deleterious effect.
It’s real – fish depend on stream-side vegetation for shade, filtering sediment, and as habitat for insects that fish eat. Livestock grazing removes that vegetation and tramples stream-banks polluting spawning gravels and redds (fish nests) with sediment that suffocates fish eggs. Grazing widens stream-channels increasing water temperature beyond tolerable levels and reduces the number of pool habitat fish need in streams. A single livestock trampling event can wipe out entire redds (fish nests) killing thousands of protected fish eggs and baby fish.
Fish need water, water use to supply stock tanks on public land and diversions that irrigate private pasture those cattle use on the off-season robs fish of the water-flow they need to survive and thrive.
I was recently interviewed by a local (Challis, Idaho) paper in response to Western Watersheds Project’s series of letters notifying government agencies of our intent to sue across central Idaho to ensure public land livestock management doesn’t unlawfully impact Bull Trout, Chinook salmon, steelhead, and Sockeye salmon. The report was honest to the issue at hand – wildlife, a rarity for this state’s media – so I thought I’d post it :

It’s time to do something about the egregious mismanagement of these important and valued Idaho fisheries :
