  WDFW -- Pygmy Rabbit Recovery Plan
Because of low numbers and limited distribution, pygmy rabbit populations in Washington are vulnerable to fire, disease, intense predation, and the random variation in birth and death rates, sex ratios, and combinations of demographic parameters that sometimes cause the collapse of small populations.
This document summarizes the current status of pygmy rabbits in Washington, reassesses and prioritizes the strategies and tasks of the initial (1995) Washington State Recovery Plan for the Pygmy Rabbit and provides an overview of emergency measures needed to prevent extinction of Washington's pygmy rabbit.
Genetic analyses of pygmy rabbits in Montana, Idaho, Oregon, and Washington have confirmed that the Washington population of pygmy rabbit is distinct and isolated from the rest of the species' range, and has been separated for thousands of years.

 rabbit. The Columbia Encyclopedia, Sixth Edition. 2001-05
Although usage varies, the term rabbit generally refers to small, running animals, with relatively short ears and legs, which give birth to blind, naked young, while hare refers to larger, hopping forms, with longer ears and legs, whose young are born furred and open-eyed.
Rabbits are chiefly nocturnal, although they are sometimes seen in the daytime.
Domestic rabbits, which may be various colors but are commonly white, are bred for food and for their fur, which is much used in making fur trim and felt.

 Pygmy Rabbit - Wikipedia, the free encyclopedia
The Pygmy Rabbit is the smallest Leporid in North America, with mean adult weights from 375 to about 500 grams (0.8 to 1.1 pounds), and a body length from 23.5 to 29.5 centimeters (9¼ to 11½ inches), females are slightly larger than males.
The pygmy rabbit is distinguishable from other Leporids by its small size, short ears, gray color, small hind legs, and lack of white fur on the tail.
The historic distribution of the pygmy rabbit included much of the semi-arid, shrub steppe region of the Great Basin and adjacent intermountain zones of the conterminous western United States, and included portions of Montana, Idaho, Wyoming, Utah, Nevada, California, Oregon, and Washington.

 EPA: Federal Register: Endangered and Threatened Wildlife and Plants; 90-Day Finding on a Petition To List the Pygmy ...
Pygmy rabbits are known to travel up to 0.75 mile (mi) (1.2 kilometers (km)) from their burrows (Gahr 1993), and there are a few records of individuals moving up to 2.2 mi (3.5 km) (Green and Flinders 1979; Katzner and Parker 1998).
Pygmy rabbits, in general, prefer taller, denser sagebrush cover relative to the surrounding landscape, which can be greater than the 10 to 30 percent range (Green and Flinders 1980b; Weiss and Verts 1984) suggested for various sage grouse habitats.
Because the pygmy rabbit is a habitat specialist, and its climax- type habitat is highly fragmented and occurs across the landscape, the petition contends the species' life history traits could affect population viability.
