Pygmy rabbit(Brachylagus idahoensis)The pygmy rabbit (Brachylagus idahoensis) is a member of the family Leporidae, which includes hares and rabbits. It is the smallest Leporid in North America. Adults weigh approximately one pound and are approximately one foot in length. The pygmy rabbit historical range includes portions of the following states: California, Oregon, Nevada, Idaho, Montana, Wyoming, Utah and Washington. On March 5, 2003, the Columbia Basin Distinct Population Segment of the pygmy rabbit was listed as endangered in the state of Washington. Pygmy rabbits are typically found in areas of tall, dense sagebrush (Artemisia spp.) cover, and are highly dependent on sagebrush to provide both food and shelter throughout the year. Their diet in the winter consists of up to 99 percent sagebrush. The pygmy rabbit is believed to be one of only two Leporids in Northern America that digs its own burrows. Pygmy rabbit burrows are typically found in relatively deep, loose soils of wind-borne or water-born origin. They occasionally make use of burrows abandoned by other species and as a result, may occur in areas of shallower or more compact soils that support sufficient shrub cover. A formal listing petition was received from environmental groups in April, 2003. that required the Service to make a determination on whetherthere was substantial information to initiate a status review of the pygmy rabbit. This decision is called a 90-Day finding and is based on scientific information provided in the petition. To view the 90-Day finding please use the the links below:
