Dataset: geographical location of areas occurring Peltogyne gracilipes (Leguminosae) individuals in ecotone forests, State of Roraima, northern Brazilian Amazon

The dataset provides information on points of occurrence of Peltogyne gracilipes (a endemic tree species; Leguminosae) in an area of ~ 450,000 ha, with the geographic center of Maracá Island and its surroundings, State of Roraima, northern Brazilian Amazon (https://data.mendeley.com/datasets/2j354jtddx/2; https://data.mendeley.com/datasets/ctv52cbkp8/2). The points of occurrence of P. gracilipes (135 points) were collected with GPS, indicating the areas of presence / absence of the species. Fieldworks were carried out in the eastern and central areas of Maracá Island (12/14/2018 and 27-28/02/2019), and close to the Vila Trairão (12/17/2018) and Vila Paredão (28 / 01/2019). All of them are natural forest areas where P. gracilipes occurs. The dataset consists of four files: (i) study_site - a figure indicating the location of the study area; (ii) occurrence_p-gracilipes_maracá - geographic location (lat / long - WGS84 - UTM - 20N) of the points of occurrence of P. gracilipes on Maracá Island; (iii) occurrence_p-gracilipes_paredão - geographical location (lat / long - WGS84 - UTM - 20N) of the points of occurrence of P. gracilipes in Vila Paredão; (iv) occurrence_p-gracilipes_trairão - geographical location (lat / long - WGS84 - UTM - 20N) of the points of occurrence of P. gracilipes in Vila Trairão.
