Modelado de la distribución espacial de árboles exóticos invasores (AEI) en el Parque Nacional Pre-Delta (Entre Ríos, Argentina)

Abstract

Se estudió la distribución espacial de árboles exóticos invasores (AEI) en el Parque Nacional Pre-Delta (PNPD-Entre Ríos, Argentina) mediante el empleo de técnicas de muestreo a distancia. Se modeló la distribución potencial mediante la técnica de interpolación Kriging. Se comparó la cartografía generada con un mapa de zonificación del PNPD y con cartografía de unidades ambientales identificadas en función de un gradiente topográfico. Se registraron datos estructurales del bosque, fenológicos de los árboles y de las acciones de control por parte del personal del PNPD, a fin de caracterizar los procesos de invasión. Se obtuvo cartografía de la distribución potencial de Melia azedarach L., Broussonetia papyrifera (L.) L'Hér. ex Vent., Ligustrum lucidum W.T. Aiton, Brachychiton populneus (Schott & Endl.) R. Br., Fraxinus sp. L. y Morus alba L. Esta última resultó ser dominante en el PNPD en los tres sectores estudiados (barrancas, islas y zona alta). En cuanto a las acciones de manejo de especies exóticas de los agentes del PNPD, cerca del 50% de los ejemplares de M. alba sujeto a aplicaciones de control mecánico (técnica de anillado) presentaron rebrotes, indicando su alta capacidad de supervivencia.

Spatial distribution of alien trees was studied on Pre-Delta National Park (PNPD-Entre Ríos, Argentina), by distance sampling techniques. Potential distribution was modelled by Kriging interpolation technique. Generated maps were overlapped with PNPD zonification map and environmental units map. We recorded forest structural data, tree phenology and tree control management actions, in order to characterize the processes of invasion. We obtained maps of potential distribution of Melia azedrach, Broussonetia papyrifera, Ligustrum lucidum, Brachychiton populneus, Fraxinus sp. and Morus alba L. The latter was the dominant species in all studied sectors (cliffs, islands and highlands). As for the management actions carried out with trees of the PNPD, about 50% of the specimens of M. alba subjected to mechanical control (banding technique) showed regrowth, indicating its high survival capacity.
