Tree species diversity and carbon stock of trees on farms in the Nicaragua-Honduras Sentinel Landscape uri icon

abstract

  • The current data sets were generated as part of the master thesis entitled 'Diversity and carbon storage in two sites with different degrees of agriculture intensification in Nicaragua', done by Willan Caicedo as part of the CATIE master program in Agroforestry and Sustainable Agriculture 2014-2016. The study was part of a multidisciplinary program in the Nicaragua-Honduras Sentinel Landscape that aims to understand the presence and contribution of tree on farm to ecosystem processes, food security and livelihood (see detail in the website www.paisagecentinela.org). Complementary, spatial information for this study is available in the www.landscapeportal.org. The study was done in two Nicaraguan municipalities, El Tuma - La Dalia and Waslala. In each site 45 farms were selected and their six predominant land uses (plot) were sampled: coffee plantations, cacao tree, living fences, basic grains, pastures and home gardens. In each plot tree, banana and palm individuals with a diameter at breast height (DBH) ≥ 9.9 cm (≥ 4.8 cm DBH trees in the case of Citrus sp.) were recorded. Every individual was identified in the field using its local or scientific name. For species with difficult identification plant material was collected and sent to the Herbarium of the National Autonomous University of Nicaragua, UNAN-León for subsequent taxonomic identification. Other complementary variables measured at individual level were: diameter at breast height (DBH; 1.30 m above the ground); commercial stem height (from the ground to the usable height), and total height of individuals (from the ground to the apex). When individuals have several stems, each one were independently measured and then the mean square diameter per individual was calculated. For Citrus trees that were highly branched below 1.30 m above the ground, the diameters was measured at 0.30 m above ground.
