Canada Lynx (Lynx canadensis) The Canada lynx is a secretive, forest-dwelling cat of northern latitudes and high mountains. It historically inhabited much of Canada, the forests of northern tier States, and subalpine forests of the central and southern Rockies. Its range in the contiguous United States included parts of Washington, Oregon, Idaho, Montana, Utah, Wyoming, Colorado, Minnesota, Wisconsin, Michigan, New York, Vermont, New Hampshire, Maine, Pennsylvania, and Massachusetts. At present, however, the FWS is only able to confirm the presence of lynx south of Canada in Maine, Montana, Washington, and possibly Minnesota. Therefore, on July 8, the FWS proposed to list the contiguous U.S. population segment of the Canada lynx as threatened.
The listing proposal cited a number of causes for the decline of lynx populations, including the loss or modification of habitat due to such activities as logging, road construction, development of skiing facilities, and urban sprawl. Over-exploitation in the past for the fur trade and increased human-induced changes to suitable habitat that have allowed the spread of competing species.
Included in the listing proposal was a special rule that would allow regulated taking and interstate transport of lawfully obtained captive-bred lynx.
Bull Trout (Salvelinus confluentus) In the June 10 Federal Register, the FWS proposed to list the Coastal-Puget Sound (Washington), Jarbridge River (Idaho and Nevada), and St. Mary-Belly River (Montana) population segments of the bull trout as threatened. The proposal includes a special rule to allow the take of bull trout under certain circumstances, which would permit continuation of recreational fisheries within the species' range.
The bull trout, a member of the char subgroup of the salmon family, is native to the Pacific Northwest, including Washington, Oregon, California, Idaho, Montana, Nevada, Alaska, and the Canadian provinces of Alberta and British Columbia. It is not in danger in parts of its range, although it is extinct in California. This species requires very cold water for egg incubation, juvenile rearing, and spawning. Threats to some bull trout populations include habitat degradation and fragmentation, blockage of migratory corridors, poor water quality, certain past fisheries management practices, and the introduction of non-native trout species.
Final Listing Rules
Bull Trout Concurrent with the June 10 listing proposal, the FWS made final an earlier proposal to list the Columbia River and Klamath River bull trout population segments as threatened. They face the same threats as the population segments proposed on June 10.
Steelhead (Oncorhynchus mykiss) Based on findings by the National Marine Fisheries Service, the FWS published a notice in the June 17 Federal Register formally listing several Evolutionary Significant Units (ESU) of this trout species for ESA protection. The southern California and upper Columbia River basin ESUs were listed as endangered, while the south-central California coast, central California coast, California Central Valley, Snake River basin, and lower Columbia River ESUs were listed as threatened.
Preble's Meadow Jumping Mouse (Zapus hudsonius preblei) This rare mammal currently inhabits heavily vegetated riparian habitats in seven eastern Colorado counties and two counties in southeastern Wyoming. Habitat loss and degradation caused by agricultural, residential, commercial, and industrial development have reduced its range and imperil its survival. On May 13, the FWS listed the Preble's meadow jumping mouse as threatened. FWS biologists are working with State officials to develop interim regulations, authorized under section 4 (d) of the ESA, that will allow certain activities to continue while a more comprehensive Habitat Conservation Plan is completed.
