Decline in bee diversity and abundance from 1972-2004 on a flowering leguminous tree, Andira intermix in Costa Rica at the interface of disturbed dry forest and the urban environment.

Country: Costa Rica
State: Guanacaste

Coordinate: 10° 38' N, 85° 26' W
Basis of coordinate: based on nearby landmark
Geography comments: "along the Pan American highway within one kilometer of urban residential neighborhoods of Liberia" (coordinate based on Liberia)
Climate and habitat
Habitat: tropical/subtropical dry broadleaf forest
Altered habitat: inhabited area
Protection: unprotected
Substrate: ground surface
Habitat comments: "Trees of A. inermis, ranging in age from 4575 yr in 2004, had been planted along a fence row on the east side of the highway... there was little undisturbed native habitat left around the study trees"
Life forms: bees
Sampling methods: no design, sweep nets
Sample size: 1057
Years: 2004
Sampling comments: "Twelve of the 38 [trees] flowered vigorously in late February 2004, and eight of these were sampled... Using long- handled aerial nets, a total of 96 aerial sweeps were taken in a series of steps from each tree with two collectors working together. At the upper crown level of each tree, six separate collections of eight sweeps each were taken (for total of 48). The same procedure was followed at the lower crown level of each tree for a second set of 48 sweeps"
