Determinación de la cantidad de carbono orgánico almacenado en la flora de los bofedales de la Reserva de Producción de Fauna Chimborazo

Abstract

The present research aims to: detennine the amount of organic carbon stored in the flora of the bofedales of the Chimborazo Fauna Production Reserve, and its influence by the anthropic activity; The process began with the analysis of the floristic diversity of the bofedales, through the determination of alpha (ct) and beta ([3) biodiversity indexes, later the anthropic threats of the bofedales were evaluated and finally with the determination of the amount of Organic carbon stored in the flora of the bofedales and its relation with the degree of threat detennined in conjunction with the local community. It was obtained that the diversity of flora of the bofedales is conformed by 25 families, 55 genera and 63 species, the families that stand out are Asteracea, Poaceae, Apiaceae and Rosaceae. Biodiversity is average with values between 2.2 and 3.3 (Margalef) represented by Plantago rigida, Deyeuxia rigescens Oreobolus ecuadorensis and Distichia muscoides. The structure and functioning of this ecosystem is determined by the ecological importance of 30 species. As for threats, 62.1% of the bofedales corresponds to the high category of alteration, while 37.9% of the bofedales are located in the category of media alteration. The bofedales that have the greatest amount of organic carbon stored in the flora by sampling area are: Pampas Salasaca, with 7.09 Ton / Ha; Portal Andino, with 2.76 and Lazabanza with 2.55 Ton / Ha; while the less carbonated reservoirs are: Puente Ayora l, with 0.52 Ton / Ha and Puente Ayora 3 with 0.51 Ton / Ha. It is necessary to apply a follow-up study, for the floristic composition of the bofedales, since with an annual record it is possible to compare and identify the changes with respect to the

composition of the flora of these ecosystems and to understand the related processes.
