          Abstract

          Resumen: Debido al aumento de las concentraciones de gases efecto invernadero y el deterioro de áreas verdes en la región metropolitana de Cochabamba, la Serranía San Pedro llega a representar un área verde importante dentro del paisaje urbano. Considerando que la serranía, todavía posee una cobertura vegetal nativa e casi toda su superficie, el presente estudio tuvo como objetivo estimar la fijación de carbono en los diferentes tipos de cobertura vegetal de la Serranía San Pedro, mediante métodos de estimación de biomasa no destructivos para contribuir a la gestión de esta función ambiental. La metodología utilizada fue la aplicación de ecuaciones alométricas en las coberturas de bosques y arbustales, para herbazales se calculó en base a la biomasa seca obtenida por la diferencia de peso seco y peso húmedo en laboratorio. La cobertura con mayor fijación de carbono por hectárea fue el bosque abierto (35,34 tC ha-1) y el de menor fijación de carbono por hectárea fue el herbazal (0,89 tC ha-1). Se observó que el área ocupada por las coberturas vegetales es importante y determinante para el valor de fijación de carbono total. Debido a la relación positiva entre conservación y fijación de carbono, se propusieron estrategias para el mantenimiento y fortalecimiento de la capacidad de fijación de carbono enfocadas en la restauración de la vegetación y control de presiones antrópicas.

          Abstract: Due to the increase in greenhouse gas concentrations and the deterioration of green areas in the metropolitan region of Cochabamba, the San Pedro Mountain range represents an important green area within the urban landscape. Considering the deterioration of the mountain range (loss of vegetation cover), the objective of this study was to estimate the carbon fixation in the different vegetation covers of the San Pedro Mountain range, using biomass estimation methods to contribute to the management of this environmental function. The methodology used was the application of allometric equations in forest and shrub cover. The grasslands were extracted, dried and weighted in the laboratory. The cover with the highest carbon fixation per hectare was the open forest (35.34 tC ha-1) and the one with the lowest carbon fixation per hectare was the grassland (0.89 tC ha-1). It was observed that the area occupied by vegetation cover is important and decisive for the total carbon fixation value. Due to the positive relationship between conservation and carbon fixation, were proposed strategies for the maintenance and strengthening of carbon fixation capacity focused on vegetation restoration and control of anthropogenic pressures.

          Improved allometric models to estimate the aboveground biomass of tropical trees.

          Terrestrial carbon stock mapping is important for the successful implementation of climate change mitigation policies. Its accuracy depends on the availability of reliable allometric models to infer oven-dry aboveground biomass of trees from census data. The degree of uncertainty associated with previously published pantropical aboveground biomass allometries is large. We analyzed a global database of directly harvested trees at 58 sites, spanning a wide range of climatic conditions and vegetation types (4004 trees ≥ 5 cm trunk diameter). When trunk diameter, total tree height, and wood specific gravity were included in the aboveground biomass model as covariates, a single model was found to hold across tropical vegetation types, with no detectable effect of region or environmental factors. The mean percent bias and variance of this model was only slightly higher than that of locally fitted models. Wood specific gravity was an important predictor of aboveground biomass, especially when including a much broader range of vegetation types than previous studies. The generic tree diameter-height relationship depended linearly on a bioclimatic stress variable E, which compounds indices of temperature variability, precipitation variability, and drought intensity. For cases in which total tree height is unavailable for aboveground biomass estimation, a pantropical model incorporating wood density, trunk diameter, and the variable E outperformed previously published models without height. However, to minimize bias, the development of locally derived diameter-height relationships is advised whenever possible. Both new allometric models should contribute to improve the accuracy of biomass assessment protocols in tropical vegetation types, and to advancing our understanding of architectural and evolutionary constraints on woody plant development. © 2014 John Wiley & Sons Ltd.
