Resumo(s)
The interest on the estimation of forest biomass, regulation of carbon sequestration and nutrient cycling has increased over the past decade. Forest in Spain are important resources of timber and other forest products. Therefore, it is necessary to estimate and to understand the potential role of forests in the mitigation of global warming effects. Up to now, few studies have been conducted to estimate the biomass carbon accumulation of Spanish forest ecosystems. With current data, we developed a forest growth model wich considered the structure variables of forest growth. The main focus of this study is to provide an estimation framework based on growth of Maritime pine (Pinus pinaster Aiton) and Scots pine (Pinus sylvestris L.)stands. We developed a model to estimate woody biomass and carbon sequestration under different ecoregions. Data were analyzed throughout the last decade. As expected, factors related to density and site productivity interacted on woody biomass production of forest stands. Due to these interactions, managers need more tools for forest management, knowledge of different forest structure and practical silvicultural methods.
