La flora leñosa establecida luego de las quemas en el valle de Chanchamayo - Selva central del Perú

Abstract

On the last decades, forest fires in the rainforest of Central Peru have been increasing, causing effects on the forest’s vegetation. The affected areas have gone regenerating. However, information about richness and floristic composition are scarce in this region. In the current study we assessed the woody flora in forests of three ages (5, 10 and 25 years) affected by forest fires and installed 9 transects (2 x 500 m); individuals with a DBH (measured at 1.3 m from the ground) ≥ 2.5 cm were measured. In the forests of 5, 10 and 25 years it was found the following: the more abundant fami- lies were Asteraceae and Euphorbiaceae; Fabaceae and Asteraceae; and Malpighiaceae and Pipera- ceae respectively; and more abundant species were Vernonanthura patens (Kunth) H.Rob, Acalypha sp., y Celtis pubescens Spreng.; Machaerium inundatum (Mart. ex Benth.) Ducke, Dendrophorbium sp. y Trema micrantha (L.) Blume; y Heteropterys laurifolia (L.) A. Juss., Piper aduncum L. y Allo- phylus floribundus (Poepp.) Radlk. respectively. Likewise, it was found 36, 95 and 220 individuals on average; 6, 12 and 36 species; 6, 11 and 34 genera; 4, 10 and 23 families for the forest of 5, 15 and 25 years, respectively
