|Scientific Name:||Sylvilagus cognatus|
|Species Authority:||Nelson, 1907|
|Taxonomic Notes:||There are no recognized subspecies of Sylvilagus cognatus, which was formerly included as a subspecies of S. floridanus (Hall 1981).|
|Red List Category & Criteria:||Data Deficient ver 3.1|

Very little is known about the status, range, and threats to Sylvilagus cognatus. Due to its restricted range, it is likely to be threatened, but the status is not currently known. More research is needed before an informed assessment can be made.
|Range Description:||Sylvilagus cognatus occurs in the Manzano Mountains of New Mexico, USA (Hall 1981). It is known from the type locality within the vicinity of Rea Ranch, New Mexico, on the “northeast side of Bosque Peak, at 2,880 m” elevation (Frey et al. 1997). There are records of a specimen found in 1956 on the eastern slope of the Sandia Mountains, at 8,500 ft, and another was possibly sighted at 11,650 ft near Sandia Crest (Ivey 1957) but it is unclear whether the Sandia Mountains are included in its current distribution.|

|Population:||There is no information available about the population status of Sylvilagus cognatus.|
|Habitat and Ecology:||Sylvilagus cognatus occurs in a high elevation area where conifer forest dominates. It is unknown what type of cover S. cognatus requires. It is assumed that habitat requirements and ecology are similar to S. floridanus.|
|Major Threat(s):||The threats to Sylvilagus cognatus are not known, but the New Mexico Drought Task Force indicates that the species may be affected by loss of habitat, drought, and wildfire (New Mexico Drought Task Force 2005). The degree of threat is not known.|
|Conservation Actions:||As a recently split and relatively unstudied species, there are currently no conservation measures in place for Sylvilagus cognatus. Research is needed to determine the population status, threats, and habitat requirements for this species before recommendations can be made.|
