Ilha Grande, located in Angra dos Reis, Rio de Janeiro, is one remnant of Atlantic Forest, presenting a mosaic of conservation units, and due to its island characteristic, it constitutes a bounded independent ecosystem, presenting vast biodiversity in endemism and making the vulnerability. The knowledge of the flora has gaps, due to difficulty of access to certain areas and areas altered by anthropic action. The objective was to generate and evaluate the Flora species of Ilha Grande, belonging to the Red List. The species list was based on data reported on the websites of the virtual herbariums and consulted literature. A total of 84 species were found, among which five as CR, 24 EN, 40 VU, and 15 NT, also, 18 with DD. Four of these species are found on the most accessible trails by tourists, and 12 are endemic of state. Only 23 species had sufficient data to assess their degree of threat to Ilha Grande, and 15 of these changed their status to CR. The great majority of the species were recorded in the south and southeast sides of the island. This work provides subsidies to make decisions and create public policies, in a priority area for conservation.
