Dinámica De La Vegetación Después De Fuegos Recientes En Los Páramos De Buenavista Y Chirripó, Costa Rica (Vegetation Dynamics Following Recent Fires In The Buenavista And Chirripó Páramos Of Costa Rica), Sally P Horn

Geography Publications and Other Works

Field studies following fires in the Buenavista (La Muerte Massif) and Chirripó páramos demonstrate that woody species show varying responses to fire. The bamboo Chusquea subtessellata and the ericaceous shrubs Vaccinium consanguineum and Pernettya prostrata typically resprout vigorously after fire, but rarely if ever recolonize burn sites by seeding. The shrub Hypericum irazuense, in contrast, generally suffers high mortality in páramo fires, but successfully reestablishes by seed following all but the largest fires. Preexisting vegetation, fire characteristics, and site differences both before and after burning likely affect rates of shrub and herb survival, colonization, and growth in páramo burn …
