FERNANDEZ-HILARIO, Robin. Spatial distribution of the regeneration of Weinmannia lechleriana (Cunoniaceae) in a montane forest of the San Alberto Sector, Yanachaga-Chemillén National Park (Peru).

We studied the natural regeneration of Weinmannia lechleriana Engl. (Cunoniaceae) in a montane forest of the San Alberto Sector (Yanachaga-Chemillén National Park) in the central jungle of Peru. The natural regeneration was evaluated around ten mature trees, through the establishment of four transects of 20 meters in length. A total of 276 individuals were found around the ten trees, 57.2% corresponded to the category of seedlings, 40.9% of the saplings and only 1.8% to the category of poles. The average of natural regeneration individuals was 27 per evaluated tree, and the highest regeneration density was found between three and six meters around the tree, and then decreasing with increasing distance. Furthermore, a greater total abundance of individuals was found in the western transects and in trees evaluated in slope, but it would be necessary to evaluate a greater number of trees in order to reach a conclusion. Finally, we can indicate that Weinmannia lechleriana apparently would not present regeneration problems in the study area and it is recommended to continue with the studies of this species
