Environment
Habitat: tropical/subtropical dry broadleaf forest

Altered habitat: clearcut

Protection: biosphere reserve

Substrate: ground surface

MAT: 15.0

MAP: 1500.0

Habitat comments: "Five main forest habitats occur at ECLJ: pine forest, pine–oak forest, cloud forest, oak forest, and gallery forest, in addition to disturbed areas... We studied mature cloud forest and disturbed cloud forest"
"pronounced seasonal variation results in 3 predictable seasons; dry-hot season (March–June), rainy season (July–October), and dry-cold season (November–February; Cuevas 1994)... Disturbed areas were agricultural fields placed in patches of cleared cloud forest and abandoned 15–20 years ago... Vegetation was <5 m in height and was composed mainly of grasses and herbs"

Sampling comments: there were two grids and "One hundred Sherman live traps (23 by 7.5 by 9 cm) were set in each site along 10 by 10 stations with 10-m spacing... Traps were operated for 3 days each month from April 1994 through May 1995, for 12,600 trap nights in disturbed areas and 15,642 trap nights in cloud forest"
