Demografia de geonoma gamiova em área de extrativismo foliar

Abstract

The leaves of Geonoma gamiova Barb. Rodr. are an important resource to floriculture, where they are used specially in funeral floral ornaments. Aiming to generate subsidies to sustainable management of this resource, results from the evaluation of the population structure of this species are presented. The research was performed in Sub-Montane Atlantic forest submitted to leaf harvesting of G. gamiova (Rasgadinho community, Guaratuba Mun., Paraná Brasil; 25 45'S e 48 46'W). It was registered high density of this species, mainly in younger stages, characterizing a J-inverted population. It was found 448 leaves commercially acceptable in the 0.5ha plot with a history of intense leaf harvesting. The population showed a high potential of regeneration and clustered spatial distribution (Id>1). Based on these data, it is discussed the sustainability of the cited harvesting activity.
