Fisheries Management, Amphibians, and Other Biota: What's the Problem?

R. Bruce Bury USGS Forest and Rangelands Ecosystem Science Center, Corvallis, OR

Up to 95% of montane waters in the West were fishless historically, and lowland areas were populated by a diversity of endemic species. However, introductions of nonindigenous fishes have impacted native amphibians, insects and other biota. Today, we need to decide if we should maintain the status quo (a major recreational fisheries in montane regions and a menagerie of introduced species in lowlands), return the waters to earlier states (the "pristine" vision) or create a hybrid of these options in specific areas. Managers face a vocal constituency of fishermen vs. wilderness purists, and recreational users vs. timber/mining interests. Still, we need to consider objectively all views with respect and open minds. We should strive to: (1) determine the response and extent of impact on native biota from introduced fishes; (2) concentrate fish planting in heavily-used areas and reduce it in backcountry waters; and (3) remove introduced fishes from those waters that are most vulnerable to invasive species. Even with conflicting mandates, a common trust or goal is the best path for achievement of positive results: continued fishing opportunities at many but not all sites, and a rebound in the biodiversity of resident biota.
