Abstract

OLIVA, Manuel et al. Quantification of the tall grass area of the Gocta and Chinata microbasins and their potential as a carbon stock. Scientia Agropecuaria [online]. 2017, vol.8, n.3, pp.233-241. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2017.03.06.

The quantification of the areas with presence of pajonales and the amount of carbon retained by them were carried out. The quantification of areas was done by the manipulation and interpretation of satellite images. For the biomass calculation of the pajonales, Harvest method were established, taking into account two quadrants of 1 m per 1 m for each hectare. Subsequently, all vegetation whose roots were removed from the interior of the quadrant was recorded, the total fresh weight per square meter was recorded and a sub-sample was collected for the subsequent production of dry biomass and its respective botanical identification. In addition, the identification of the associated plant species. As a result, distribution maps of the tall grass were generated in the high side of the microbasin of the Gocta and Chinata waterfalls. The area of tall grass is 46.30 km2, distributed between the Gocta and Chinata micro-basins, where the plant species of the Poaceae family predominate, with a percentage of 79% of area covered with vegetation. 10.1 t/ha of carbon were obtained.

Keywords : waterfall; dry biomass; tall grass; microbasin; global warming.
