Brazilian protected areas are essential for the conservation of plants of the Atlantic Forest domain, one of 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the richness of plants protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism, and conservation in the PNC that could not be included in the list. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN, or VU) by the Brazilian National Red List, seven as data deficient (DD), and five as priorities for conservation."Parque Nacional do Caparaó" houses 8% of the land plant species endemic to the Brazilian Atlantic Forest, including 6% of its angiosperms, 31% of its lycophytes and ferns, and 14% of its avascular plants. Twelve percent of the threatened species listed for the state of Espírito Santo and 7% listed for the state of Minas Gerais are also protected by PNC. Surprisingly, 79% of the collections analyzed here were carried out in Minas Gerais, which represents just 21% of the total extension of the park. The compiled data uncover a huge botanical collection gap in this federally protected area.
