Endangered and Threatened Wildlife and Plants; Determination of 
Endangered Status for Sidalcea oregana var. calva (Wenatchee Mountains 
Checker-Mallow)

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), determine 
endangered species status under the Endangered Species Act (Act) of 
1973, as amended, for Sidalcea oregana var. calva (Wenatchee Mountains 
checker-mallow). This plant species is endemic to meadows that have 
surface water or saturated soil in the spring and early summer at 
middle elevations in the Wenatchee Mountains of Chelan County, 
Washington. Although five populations of this plant are known, three of 
these have very few individuals. The estimated total number of plants 
is about 3,300. The primary threats to S. oregana var. calva include 
habitat fragmentation and destruction due to alterations of hydrology, 
rural residential development and associated activities, competition 
from native and alien plants, recreation, fire suppression, and 
activities associated with fire suppression. To a lesser extent, the 
species is threatened by livestock grazing, road construction, and 
timber harvesting and associated impacts including changes in surface 
runoff in the small watersheds in which the plant occurs. This rule 
implements the Federal protections provided by the Act for this plant.

EFFECTIVE DATE: This final rule is effective January 21, 2000.

ADDRESSES: The complete file for this rule is available for inspection, 
by appointment, during normal business hours at the Western Washington 
Office, North Pacific Coast Ecoregion, U.S. Fish and Wildlife Service, 
510 Desmond Drive, Suite 102, Lacey, WA 98503-1273.
