Geography comments: "in the Municipality of San Cristobal de las Casas" at Alcanfores

Environment
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)
