Screening trial of 14 tropical hardwoods with an emphasis on species native to Costa Rica: Fourth year results

Abstract

Fourth year results are presented from a species screening trial established at the La Selva Biological Station in northeastern Costa Rica. Of the 14 tropical hardwood species evaluated on survivorship, growth, form, and volume the most promising were (survival, diameter and height): Vochysia guatemalensis (84%, 12.2 cm, 10.5 m); Vochysia ferruginea (79%, 9.7 cm, 7.8 m); Hyeronima alchorneoides (83%, 8.1 cm, 7.9 m); Dipteryx panamensis (78%, 5.5 cm, 7.2 m); and Calophyllum brasiliense (80%, 6.3 cm, 6.2 m).
