Geography
Country: Madagascar
Coordinate: -12.4649° S, 49.1021° E
Coordinate basis: stated in text
Geography comments: "approximately 85km south of Antsiranana"
Environment
Habitat: tropical/subtropical moist broadleaf forest
Altered habitat: disturbed forest
Substrate: ground surface
Disturbance: grazing,selective logging
MAT: 29.0
MAP: 2328.0
Habitat comments: "The majority of secondary forest fragments have been altered with the introduction of productive species" and there is "zebu grazing, selective logging and charcoaling"
mean precip is 14 mm per day from November to March (= 2114 mm) and 1 mm per day from April to December (= 214 mm); MAT is 28 during the dry season and peaks out at 31 during the wet season, so 29 seems like a good guess
