RT Journal Article SR Electronic T1 Understory Species Richness during Restoration of Wet Tropical Forest in Costa Rica JF Ecological Restoration FD University of Wisconsin Press SP 22 OP 26 DO 10.3368/er.26.1.22 VO 26 IS 1 A1 Leopold, A. Carl A1 Salazar, Jackeline YR 2008 UL http://er.uwpress.org/content/26/1/22.abstract AB An effort to restore wet tropical forest in Costa Rica began in 1993 with plantings of native trees in abandoned pasture land. We compared understory plant species richness in three sites planted with a mix of native tree species with under-story species in two monoculture plantations and in two secondary growth (unplanted) areas. Understory species in nearby primary forest remnants are also reported for comparison. We identified 356 understory species, ranging from 46 to 134 understory species per plot. Woody species were predominant (50–80%), as were plant species relying on animals for seed dispersal (60–80%). Our data indicate that substantial progress toward understory species richness can be obtained in the first decade of wet tropical forest restoration.
