 Despite the area 's dry climate , a few year @-@ round streams provide habitat for the rare <unk> <unk> trout . Fish populations in the <unk> Creek Mountains declined throughout much of the 20th century . In the 1980s , the effects of grazing <unk> on riparian zones and the fish led to land @-@ use conflict . The <unk> Creek Mountain Working Group was formed in 1988 to help resolve disagreements among livestock owners , environmentalists , government agencies , and other interested parties . The <unk> met and agreed on changes to land @-@ use practices , and since the early 1990s , riparian zones have begun to recover .
