## Abstract

We, the U.S. Fish and Wildlife Service (Service), designate critical habitat for the Preble's meadow jumping mouse (Zapus hudsonius preblei) pursuant to the Endangered Species Act of 1973, as amended (Act). The designation includes 8 habitat units totaling approximately 12,632 hectares (ha) (31,222 acres (ac)) found along 578.1 kilometers (km) (359.2 miles (mi)) of rivers and streams in the States of Colorado and Wyoming. The designation includes river and stream reaches and adjacent areas in the North Platte River and South Platte River. The critical habitat designation defines the width of designated critical habitat as a distance outward from the river or stream edge (as defined by the ordinary high water mark) varying with the size (order) of a river or stream. This publication also provides notice of the availability of the Addendum to the Economic Analysis of Critical Habitat Designation for the Preble's Meadow Jumping Mouse (Addendum to the Economic Analysis) and the final Environmental Assessment for Designation of Critical Habitat for the Preble's Meadow Jumping Mouse (EA) for this final rule.
