ABSTRACT
Six vegetation types are described for Poço das Antas Biological Reserve, Rio de Janeiro State, Brazil (22º30' e 22º33'S; 42º15' e 42º19'W). Two forest formations (alluvial forest and submontane forest) and four non-forest formations (fluvial pioneer, alluvial scrub, submontane scrub and manmade grasslands) were identified. Relevant floristic and physiognomic characteristics of each unit are described and compared to analogous Atlantic Rain Forest formations. The vegetation was mapped using analog photo interpretation on a scale of 1:20,000. An estimated 2,608 ha of forest remnants in various states of preservation were detected (alluvial forest - 17.9%; submontane forest- 34.3%), plus a significant representation of non-forest formations with fluvial influence (20.0%) and manmade interference (27.9%).
