Identificación de rasgos funcionales de especies vegetales del Bosque Altoandino Y Páramo relacionados con su respuesta regenerativa postfuego

Abstract

There is an increase in the frequency, intensity and area affected by forest fires in Colombia (mostly of anthropic origin), which generate consequences and this phenomenon also ocurrs in the Cerros Orientales of the city of Bogotá, DC, which is why the Jardin Botanico de Bogota (JBB) has prioritized the knowledge of plant coverings by fire. One way to determine the sensitivity of an ecosystem to fire events is to study functional traits of the present plant species; so this study seeks to identify the traits of high andean forest and paramo plants in Cerro Aguanoso, associated with the post-fire regenerative response. This bibliographic compilation was made for the 112 species identified in the vegetation surveys carried out by the JBB. 17 functional traits were obtained, which are organized from lowest to highest more information found: emergence of post-fire seedlings, pregerminative treatment, seed type by storage, presence of seed bank, presence of secondary metabolites, resprouting capacity, leaf texture , presence of pubescence, type of fruit, number of seeds per fruit, mechanism of dispersion, habit, height, ecological guild, dimensions of the leaf, presence of thorns and life story. An analysis of the traits with more information was made where he identified that the arboreal habit is the one that presents a higher resistance to fire events, where the heliophyte guild combined with dispersion of fruits in achenes, berries and capsules by zoocoric or anemocoric mechanism has a greater regenerative response; and finally, perennial species have greater resistance with respect to decisions. A list of species is recommended for post-fire restoration processes and the investigation of traits with less information and their gaps.
