Efectos del cambio climático en los patrones de captura de carbono y distribución de especies en zonas de recarga hídrica de la microcuenca carrizal, año 2019

The calculation of the carbon capture and distribution patterns of six species in water recharge areas was performed: cedro (Cedrela odorata L), fernán sánchez (Triplaris cumingiana), samán (Samanea saman), guachapeli (Albizia guachapele), guayacán (Tabebuia chrysantha), white laurel (Cordia alliodora) in the micro-basin of the Carrizal River, in 3 study areas, Julián, Severino and Balsa communities in the Middle, for which an inventory of all individuals by species was prepared, recording dasometric data as height and DAP; With the number of registered individuals, a neural network was created in Gephi version 0.9.2., in which the dispersion ranges of the species were plotted, along with this, the changes in precipitation and temperature in the 2008 period were evaluated -2018 whose averages were obtained from the database of the M0162 weather station (Chone - U. Católica) of the National Institute of Hydrology and Meteorology. 172 individuals were identified, among the six species studied, of which the most abundant was Cordia alliodora with 22%, followed by Triplaris cumingiana with 19.77%, in terms of abundance by families, Fabaceae is the one that stands out It presents two species with 43 individuals, equivalent to 33% of the total registered. Regarding carbon sequestration, the total value recorded in the entire area was 104.53 tons of CO2; among species, Cedrela odorata and Cordia alliodora are the ones with the highest rates 7.18 and 6.18 t C / ind / ha respectively. The changes in rainfall and temperature in the investigated period, condition the actions of the communities, so work on the application of strategies such as water and waste management, agriculture and forestry adapted to the climate and reforestation with native species from the individual, community and institutional approaches. Keywords: Forest species, adaptability, dispersion, climate
