Coussapoa curranii: an endemic species of the Atlantic Forest, rare and threatened in Rio de Janeiro state, Brazil

Abstract

Recent in situ samplings and analysis of herbarium material revealed new occurrences of Coussapoa curranii (Urticaceae). In this study, an updated distribution map is given for the species in the Brazil. Nevertheless, due to the low representativeness of individuals in forestry surveys, and its natural occurrence in environments under threat of degradation, it is necessary to categorize this species as Critically Threatened (CR) according to IUCN criteria. Also, as a result of this study and in compliance with Target 8 of the Global Strategy for Plant Conservation, the species is being grown in the Parque Botânico do Ecomuseu Ilha Grande. This park is located in the area of its most recent record of natural occurrence, Parque Estadual da Ilha Grande, Angra dos Reis, Rio de Janeiro, Brazil.
