Brachylagus

Brachylagus () is a genus of lagomorph that contained the smallest living leporid, the pygmy rabbit before it was reclassified as a member of Sylvilagus in 2022. The genus name was originally proposed by Gerrit Smith Miller Jr. in 1900 as a subgenus for the pygmy rabbit, as it then had the scientific name Lepus idahoensis, but its characteristics differed greatly from the known subgenera of the time. Marcus Ward Lyon Jr. elevated the subgenus to genus level in 1904. One extinct species, Brachylagus coloradoensis, is known to belong to the genus.

== Habitat == Pygmy rabbits are small lagomorphs that are endemic to mature sagebrush habitats. They are identified as the smallest member of the leporid family in North America. The Habitat selection studies have shown that human practices have impacted a lot of wildlife habitats. The mature sagebrush is a habitat for a lot of pygmy rabbits during every phase of their life; it is a place for both food and shelter for them. The Pygmy rabbits live in the burrow for shelter. Surprisingly, there are only 2 rabbits left in North America, which are known to evacuate their own burrows and also require suitable soil conditions. There are several factors that have led to the decline in the size of the population of the Pygmy Rabbit. These factors are intensive fire, invasive species, overgrazing, and energy development. One study has demonstrated that out of 77 sampled habitats at the occupied and unoccupied sites in Utah. The results showed that the occupied sites had greater horizontal and vertical presence of sagebrush, which is also present in greater amounts compared to the unoccupied habitat sites.
