Caracterización florística y estructural de un relicto de bosque seco tropical en el municipio de Apulo – Cundinamarca

Abstract

The Tropical Dry Forest is a plant formation that is characterized by presenting continuous forest cover, which is distributed between 0 and 1000 meters above sea level, and which has the characteristic of presenting temperatures above 24 degrees. centigrade and rainfall that is between 700 and 2000 mm annually (Alexander Von Humboldt Institute, 1998). However, this large biome turns out to be one of the most threatened in Colombia, to the extent that the country currently has 8% of relictuality with respect to the original distribution area (Pizano & García, 2014), given that it has been the favorite ecosystem for the development of human settlements, providing a long history of use and transformation, which is why the Ministry of the Environment has named it strategic. It is for the above reasons that it is essential to carry out studies that increase knowledge about this great biome in the country, since the existing information about it is minimal and the rapid population growth threatens the few relics that remain. By virtue of the above, with the present research work, the aim is to carry out the floristic and structural characterization of a relict of Tropical Dry Forest located in the municipality of Apulo, Cundinamarca, specifically in the “El Espino” village, through sampling. of 0.5 hectares, for which 5 plots will be made with a size of 0.1 hectares each and rectangular in shape (50 * 20 meters), within which, individuals that have DBH greater than or equal to 10 centimeters will be registered. and in turn, a nested design will be carried out in order to sample plants with more than 1.5 meters in height and less than 10 centimeters of DBH and plants with heights less than 1.5 meters in height. , the first in subplots of 55 meters and the second in subplots of 22 meters. It is expected that this study will strengthen knowledge about this great biome in the region, specifically with regard to woody vegetation, identifying such important aspects as climatic characterization, structure, floristic composition and diversity.
