Abstract

The decharacterization of natural environments and loss of biodiversity, through biological invasions have been cause for concern in several biomes, as they promote economic losses and threats to the genetic patrimony. This work was carried out with the objective of identifying and mapping invasive alien species in the Atlantic Forest area of ​​Mata do Junco Wildlife Refuge, SE Chapel. Data were collected using transect walking. The inventoried areas were geo-referenced and mapped using GPS and GIS platform programs. It was identified 09 species, being seven exotic and two alóctones to the region. Two exotic species are invasive: Bambusa vulgaris Schrad. Ex J.C. Wendl and Elaeis guineensis Jacq., With density of 9,675 and 750 ind.ha-1, respectively, distributed in 36.22 ha (6.17% of the total area). This research was a pioneer in this conservation unit, with significant colonization, tendentiously threatening the local biodiversity.
