Geography
Country: Costa Rica
State: Guanacaste

Coordinate: 10° 53' 1" N, 85° 46' 30" W
Basis of coordinate: based on nearby landmark
Geography comments: "25 km south of La Cruz in northwestern Guanacaste Province between the Pan-American highway and the ocean... All three sites are within 8 km of each other and their general location is 12 km from the three upland sites" (coordinate based on Santa Rosa National Park)
Climate and habitat
Habitat: tropical/subtropical dry broadleaf forest
Protection: national/state park
Substrate: ground surface
Disturbance: selective logging
MAP: 2000.0
Habitat comments: three sites "in the semidegraded forests 100-200 m inland from the thin band of mangroves backing Playa Naranjo" (nature of disturbance unclear) with the first "in thoroughly deciduous vegetation", the second in "deciduous to semievergreen" forest, and the third "in deciduous forest"; "the annual rainfall ranges from 1400 mm to 2200 mm, with a mean of -2000 mm"
Methods
Life forms: orchid bees
Sites: 6
Sampling methods: line transect, baited, other traps
Sample size: 160
Years: 1977
Seasons: dry
Nets or traps: 5
Sampling comments: "Cineole, eugenol, methyl cinnamate, benzyl acetate, and methyl salicylate were selected as the baits... 16-cm2 squares of heavy blotter paper were soaked in a compound and each square placed individually in a small plastic bag that was then knotted shut. At the census site, each of the five bags was pinned to a different tree trunk in shade - 1.5 m above the ground. The five trees were chosen so as to be about eight to 15 paces apart and arranged in a roughly straight line or shallow arc"
