Vascular Epiphyte Diversity in a Key Atlantic Forest Remnant from Minas Gerais State, Southeastern Brazil

Abstract

Vascular epiphytes contribute significantly to the biodiversity of tropical forests. We aimed to identify the epiphyte species occurring in the Muriqui Trail at Serra do Brigadeiro State Park (SBSP), a priority area for Atlantic forest conservation in southeastern Brazil. We selected 10 phorophytes, from which we sampled epiphytes and took light intensity measurements at three strata: up to 4 m, 4 to 8 m, and above 8 m. Phorophytes represented eight species, eight genera, and six families. We found 25 epiphytic species from 17 genera and nine families. Ferns showed highest richness, especially Polypodiaceae. We report herein important data on epiphyte diversity in eastern Minas Gerais state (Zona da Mata), including the occurrence of species rarely cited in surveys. Fomenting local conservation along with environmental education may be pivotal for counteracting anthropic pressure on SBSP.
