Natural Regeneration of Endangered Species in Experimental Areas in the Eastern Amazon:

This work evaluated the changes in the number of individuals in the natural regeneration of Hymenaea parvifolia Huber (jutaí-mirim), Hymenolobium excelsum Ducke (angelim-da-mata) and Vouacapoua americana Aubl. (acapu) classified as endangered by the International Union for Nature Conservation (IU...

Description
Summary:This work evaluated the changes in the number of individuals in the natural regeneration of Hymenaea parvifolia Huber (jutaí-mirim), Hymenolobium excelsum Ducke (angelim-da-mata) and Vouacapoua americana Aubl. (acapu) classified as endangered by the International Union for Nature Conservation (IUCN), in three experimental forest management areas in the State of Pará. The abundance in the populations of these species was determined by the ratio between the number of individuals of each species and the sample area in hectares. Descriptive statistics were performed. The results show that the absence of individuals in the natural regeneration of H. parvifolia and H. excelsum in the treatment with no logging and the low density of individuals in the treatments in the managed forest indicate the difficulty of these species to regenerate and establish themselves in the forest, which can lead to extinction in the area. The natural regeneration of V. americana is abundant in the area, guaranteeing its permanence, without risk of extinction.
