Geomorphological influence on vulnerability to forest fires in the Guanacaste Conservation Area, Costa Rica

Abstract

The dry tropical forest located in the North Pacific of Costa Rica is regularly affected by forest fires, which drives changes in landscape dynamics as well as in the socio-economic and ecological values of the ecosystem. The objective of the study is to determine the relationships of geomorphology in vulnerability to forest fires in the Guanacaste Conservation Area, based on the relationship between the origin and age of the parental material, as well as the dynamics, morphology and evolution of geoforms with regional climatic conditions and dry forest. A geomorphological mapping was carried out with two genetic groups: endogen-modelled (El Hacha fence, volcanic ramps of the Orosí-Cacao complex, tectonic hills of Santa Elena) and exogenous (coastal plain). A forest fire vulnerability model was used, including socio-economic and ecological components; finally, a cross-analysis between relief forms and the vulnerability model was carried out by cross-checking geospatial data. The results show that the percentage between relief shapes and vulnerability ranges indicate a pattern in morphology and behaviour in hillside composition, orientation and location. The study represents an approximation of the causal and dynamic relationships between relief forms and vulnerability to forest fires in the Guanacaste Conservation Area.
