Coordinate: 16° 43' 12" N, 92° 38' 17" W
Basis of coordinate: stated in text
Geography comments: "in the Municipality of San Cristobal de las Casas" at Alcanfores
Habitat: temperate broadleaf/mixed forest
Altered habitat: pasture
Protection: unprotected
Substrate: ground surface
MAT: 15.0
MAP: 1186.0
Habitat comments: "temperate sub-humid with summer rains, with an average precipitation and temperature of 1186 mm and 15 °C, respectively... The surrounding (suburban) vegetation includes a mosaic of successional stages associated with oak, pine-oak, and in upper parts, with cloud forest"
the site was "characterized by heavily intensified agriculture practices and agrochemical inputs, as well as by the presence of early-stage pine-oak forest regeneration" (this may mean pasture or crops because both are mentioned, but there is high cover by "grasses", and specifically 42.5% with 26% canopy cover, so pasture is a better fit)
