Between November 2006 and September 2007, the Rio de Janeiro based non-profit organisation OrquidaRio made ten visits to REGUA to survey and map the orchids on the Reserve. The project, entitled Survey and Distribution of Orchids of REGUA, was funded by the San Diego County Orchid Society and OrquidaRio registered, mapped and, where possible, photographed all the orchids they found. A total of 103 species from 49 genera were identified, including 38 species new to the Serra dos Órgãos mountain range (Miller et al., 2006).
