Dispersion capacity and self-perpetuation of planted tree species in the Zoobotanical Park of Federal University of Acre

Abstract

The natural regeneration of an area depends, among other factors, on its floristic potential and the presence of pollinators and seeds dispersers. This work aims to evaluate the self - perpetuation capacity of the tree species of the Zoobotanical Park from the point of view of the presence or absence of the dispersers. The data were obtained through interviews with PZ technicians and compared with the scientific literature. As a result we obtained 29 species and/or genera that act as seed dispersers. Almost 90% of the tree species analyzed have dispersers known in the area. Of the 42 forest species analyzed, 27 (65%) have a greater chance of being perpetuated in the PZ area, based on the abundance of their main dispersers, namely paca and/or agouti. For 7% of the analyzed forest species (Schoenobiblus peruvianus, Drypetes amazonica and Dalbergia inundata) natural dispersers are not known by the respondents nor was this information found in the scientific literature.
