Site 1. At the edge of one of the successional plots; a flat area of alluvial soil; several hectares with strips chopped by machete on a 5-year rotating cycle; trap located on east side of a recently cleared successional strip in 1993; bordered to the east by a narrow strip of mature riparian forest, a stream, and a large cattle pasture beyond La Selva's border.
Site 2. Sendero Sabalo Esquina at GIS line 1200, just south of the successional plots; alluvial soil but dissected terrain where the terrace is dropping down to a stream; extensive cattle pasture on the other side of stream; trap under canopy of tall second growth forest.
Site 3. Near junction of Sendero Holdridge and Sendero Suampo; flat alluvial soil; in small light gap in primary rainforest.
Site 4. A short distance up Camino Circular Lejano; flat alluvial soil; in small light gap in primary rainforest.
Site 5. Near junction of Camino Circular Lejano, Camino Circular Cercano, and Camino Central; residual soil and dissected terrain; a small recent light gap at edge of trail in primary rainforest.
Site 6. Half way to La Selva's back border on Camino Central; residual soil and dissected terrain; at edge of trail under canopy of primary rainforest.
Site 7. Sendero Suroeste; residual soil and dissected terrain; at edge of trail under canopy of primary rainforest.
Site 8. Sendero Suroeste; residual soil and dissected terrain; in old light gap in primary rainforest.
Site 9. Lindero Occidental, a trail which divides a broad expanse of primary rainforest and a broad expanse of young second growth forest; residual soil and dissected terrain; trap under young second growth forest, about 100m from primary forest.
Site 10. Near junction of Camino Experimental Sur and Camino Experimental Norte; alluvial soil on flat terrain; under canopy of primary rainforest.
Site 11. Sendero La Chanchera; alluvial soil on flat terrain; a large area of young second growth and abandoned palm and cacao plantations, with occasional relict trees; trap located at edge of very new large treefall gap from giant Dipteryx, in 1993; gap fairly quickly grew in with dense second growth vegetation.
Site 12. Sendero Experimental Norte; alluvial soil on relatively flat terrain; under canopy of primary rainforest.
Site 13. A few hundred meters out on Sendero Atajo; alluvial soil on flat terrain; at trail edge under canopy of young second growth forest; within 100m of primary rainforest; this site occasionally flooded.
Site 14. About half way out Sendero Sarapiqui; residual soil on dissected terrain; trap under canopy of young second growth forest.
Site 15. Sendero Sarapiqui near south boundary; residual soil on dissected terrain; trap under canopy of young second growth forest.
Site 16. Sendero Sarapiqui near south boundary; residual soil on dissected terrain; trap at edge of trail in young second growth forest.
Site 17. About 300m out on Camino Experimental Sur; a trap suspended in the canopy of a primary rainforest tree.
Site 18. 1250m out on Lindero El Peje; where trail crosses low marshy area; primary rainforest on one side, regenerating pasture on the other; trap located near a freshly fallen Pentaclethra tree at edge of marsh.
Site 19. A set of trees fell down between the lab clearing and the River Station, creating a large gap. The main trees that fell were Pterocarpus hayessi, Virola sebifera, Hampea apendiculata and Ficus cahuitensis. A trap was set in this gap 2 weeks after it was created.
