Se ha estimado la producción de biomasa (área y radical) y la fijación de CO2 para las 32 principales especies forestales de nuestros bosques (13 coníferas, 15 frondosas y 4 de laurisilva y fayal-brezal) y para los grupos de "otras coníferas", "otras frondosas" y "otras laurisilva" consideradas en el Inventario Forestal Nacional. Los resultados muestran que los bosques españoles fijan actualmente alrededor del 19% de las emisiones totales de CO2 producidas en España, lo cual les confiere un papel trascendental en el ciclo del carbono. Asimismo, los bosques españoles tienen almacenados más de 2858 millones de toneladas de CO2, constituyendo un reservorio de gran importancia que es preciso gestionar con esmero. Los bosque españoles almacenaron, en 2004, más de 1593 millones de toneladas de biomasa (materia seca). [Texto de la editorial]

To overcome these shortcomings, we apply spatially-explicit extended accounts that incorporate a novel environmental income indicator, which we test in the forests of Andalusia (Spain). Extended accounts incorporate nine farmer activities (timber, cork, firewood, nuts, livestock grazing, conservation forestry, hunting, residential services and private amenity) and seven government activities (fire services, free access recreation, free access mushroom, carbon, landscape conservation, threatened biodiversity and water yield). To make sure the valuation remains consistent with standard accounts, we simulate exchange values for non-market final forest product consumption in order to measure individual ecosystem services and environmental income indicators. Manufactured capital and environmental assets are also integrated. When comparing extended to standard accounts, our results are 3.6 times higher for gross value added. These differences are explained primarily by the omission in the standard accounts of carbon activities and undervaluation of private amenity, free access recreation, landscape and threatened biodiversity ecosystem services. Extended accounts measure a value of Andalusian forest ecosystem services 5.4 times higher than that measured using the valuation criteria of standard accounts. ; This RECAMAN project research has received financial support from Agency of Environment and Water (AMAYA); Department of Environment and Territory Planning (CMAYOT) (contract No NET165602). ; Peer reviewed
