摘要: Facing tight resource constraints, conservation organizations must allocate funds available for habitat protection as effectively possible. Often, they combine spatially referenced economic and biodiversity data to prioritize land protection. We tested how sensitive these prioritizations could be differences in the spatial grain of by demonstrating conclusion a classic debate planning between cost benefit targeting was altered based on information. As case study, we determined parcel-level acquisition costs benefits transactions recently undertaken nonprofit organization that seeks protect forests eastern United States. Then, used hypothetical plans simulate types ex ante priorities an use areas found apparent effectiveness depended when prioritizing parcels local species richness. However, accounting complementarity, consistently more efficient than strategy regardless involved. More pertinently other studies, combining collected over different grains inflated led overestimation efficiency gain offered adopting integrative return-on-investment approach. El Grano de los Datos Costo Economico con Referencia Espacial y Beneficio la Biodiversidad Efectividad una Estrategia Determinacion Costos Resumen Al enfrentar restricciones fuertes recursos, las organizaciones conservacion deben adjudicar fondos disponibles para proteccion manera mas efectiva posible. Frecuentemente combinan datos economicos referencia espacial biodiversidad priorizar suelos su proteccion. Probamos cuan sensible pueden ser estas priorizaciones diferencias en el grano estos al demostrar como un clasico planeacion entre determinacion costos beneficios fue alterado base informacion disponible. Como estudio caso, determinamos adquisicion nivel parcelas transacciones suelo llevadas cabo recientemente por organizacion sin fines lucro que busca proteger bosques este Estados Unidos. Despues usamos planes hipoteticos simular tipos prioridades podria usar Encontramos efectividad aparente dependio del usados riqueza especies. Sin embargo, representar complementariedad, eficiente consistente estrategia importar involucrados. De relevante otros estudios, encontramos combinar colectados diferentes fibras espaciales se inflo esto nos llevo sobreestimacion ganancia eficiencia ofrecida adoptar integradora regresar-al-invertir.
