【 摘 要 】

To explore the potential of native tropical hardwoods for forestry development, 84 timber species were tested in a species screening trial in Costa Rica; 17 were widely planted tropical exotics, 52 were locally indigenous, and 15 were native to other areas of Costa Rica. A complete randomized block design was used with single tree plots replicated 24 times per site. At 3 years of age, survival, form, and growth were analyzed for species at four abandoned pasture sites at La Selva Biological Station, Sarapiqui, Costa Rica. Well-known exotics selected for fast growth made up 20% of the species tested but 40% of the fastest growing ten species. Of the top 25% of the species, 67% were indigenous species, in line with the original proportion tested. Candidate species for further testing were grouped according to different forestry objectives: timber plantations, agroforestry systems, enrichment plantings, and reforestation of buffer zones. These previously untested, little-known species demonstrate the large number of native species with high potential for reforestation for a variety of objectives.
