| Abstract | The research was conducted in the months of July 2012 to October 2013 at Yacuri National Park (YNP), located in southern Ecuador, it has 43 090.6 ha and is distributed in the provinces of Loja and Zamora Chinchipe in an altitudinal range between 2120 - 3880 meters above sea level, with a temperature range of 8-16 ° C and rainfall of 750 mm in the dry months and up to 3500 mm in the rainy months. The research objectives were to develop a land cover map, determine the composition and structure of shrub and herbaceous moorlands at YNP, quantify the carbon fixed in biomass, necromass and soil of these ecosystems, and to establish the influence of biomass in fixed carbon content in the soil. Two types of moorlands (shrub and herbaceous) were studied through the installation of temporary plots of 4 m2 and 1 m2 respectively, this allowed us to determine its structure and composition. The land cover types present in the Yacuri National Park are shrub morrland, herbaceous moorland upper montane evergreen forest, mist montane forest, chaparral forest-lacustrine sector rocks and the lake system, located in young soils with high organic matter contents, shallow and well defined. The floristic diversity of the landmoors of the YNP is reflected in 62 species of vascular plants in a sampling area of 76 m2 for shrub moorland and in the herbaceous moorland 76 species of vascular plants were recorded in a sampling area of 144 m2. Eight endemic species were recorded for the shrub moorland and 11 species to the herbaceous moorland all species presenting some degree of danger according to the IUCN categories. The carbon stored in the biomass and necromass compartment in the shrub moorland is 159,05 t/C/ha and in the herbaceous moorland is 116,18 t/C/ha, while the fixed carbon content in the soil at a depth of 0.60 m is 537,06 t/C/ha for the herbaceous moorland and in the shrub moorland soils it is 471,59 t/C/ha. The biomass and carbon content in soils present a minimal relationship; therefore it was not possible to obtain a mathematical model to estimate the carbon content in the soil with respect to its biomass. |
