Presentation Title: Influence of Tropical Premontane Reforestation on Canopy Throughfall Discipline: Hydrology School: Salish Kootenai College Presentation Type: Poster Presentation Abstract: Influence of Tropical Premontane Reforestation on Canopy Throughfall Sam Wall, Salish Kootenai College

Reestablishment of the functional role of forest canopies is a key metric of success for tropical reforestation efforts. Canopies in tropical regions exert a strong influence on forest hydrology, including total precipitation reaching the ground surface, soil infiltration, overland water flow and erosion. I investigated differences in precipitation throughfall between primary and secondary forests in comparison to an un-canopied reference area within the Las Cruces Biological Station, Coto Brus, Costa Rica. Forest structure was characterized in terms of forest basal area, diameter distribution, leaf area index, and canopy transmission. The results indicate that the canopies the young secondary forests exert considerable influence on the interception of precipitation similar to primary forest canopies, both of which were generally below an uncanopied reference condition. The data suggest that the reforestation, which includes planted seedlings and natural regeneration in abandoned tropical premontane pastures, can rapidly reestablish canopy interception function.
