Endangered and Threatened Wildlife and Plants; Proposal to List the Spruce-Fir Moss Spider as an Endangered Species

الملخص

The Service proposes to list the spruce-fir moss spider (Microhexura montivaga) as an endangered species under the Endangered Species Act of 1973, as amended (Act). This spider is currently known from four mostly small populations located in western North Carolina and eastern Tennessee. The spider's damp high-elevation forest habitat is deteriorating rapidly due primarily to air pollution and exotic insects. The species' current low numbers also increase its vulnerability to harm from other threats. Listing Microhexura montivaga as an endangered species would provide protection under the Act.
