Geographic Range [top]

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.
