Human activities produce land use changes in accordance to the needs of society. This leads either to a direct exploitation of the natural resources or to an agricultural land adaptation. The objective of the present study was to estimate the carbon content of former cultivated mezquital areas with a time of abandonment of 15 and 30 years. The study areas were located near the town of Linares, Nuevo Leon. For the estimation of the carbon content a systematic sampling design was used, in each area four sampling sites of 1,600 m2 (40×40 m) divided into four quadrants were established. In quadrant I all trees and shrubs larger than 1 cm in diameter were counted. In the quadrants II, III and IV only trees over 5 cm in diameter were evaluated. The dasometric measurements made were total height (h) and diameter.
Keywords: Aboveground biomass, carbon content, mezquital
