Figure 2
Occurrence of Dimorphandra mollis Beth. plants in plots distributed in five areas (A1, A2, A3, A4 and A5) located in the Pandeiros River Permanent Preservation Area, in Bonito de Minas, Minas Gerais state, Brazil. The picture was obtained based on Normalized Difference Vegetation Index maps generated from images taken by drone flying over the evaluated areas. * The closer the pixel is to 0 (red in the image), that indicates absence of vegetation. ** The black lines represent the delimitation of the plots. *** The blue circles represent the location of all plants that have been observed.
