The value of biodiversity in reserve selection : Representation, species weighting, and benefit functions

摘要: : The limited availability of resources for conservation has led to the development many quantitative methods selecting reserves that aim maximize biodiversity value reserve networks. In published analyses, species are often considered equal, although some in much greater need protection than others. Furthermore, representation is usually treated as a threshold: either represented or not, but varying levels over under given target level not valued differently. We propose higher should also have value. introduce framework selection includes weights and benefit functions under- overrepresentation (number locations each species). applied method planning herb-rich forests southern Finland. Our use weighting changed identity about 50% selected sites at different funding improved rare threatened species. identified small area additional land would substantially enhance existing network. suggest be standard options reserve-selection applications. Resumen: La limitada disponibilidad de recursos para la conservacion ha llevado al desarrollo muchos metodos cualitativos seleccion reservas que tienen como meta maximizar el valor biodiversidad las redes reservas. En los analisis publicados, especies son consideradas iguales menudo, pesar del hecho algunas mayor necesidad proteccion otras. Mas aun, representacion generalmente es tratada umbral: una especie representada o no, pero niveles por arriba debajo un nivel determinado no valorados diferentemente. Proponemos tambien deberia tener valor. Introducimos marco referencia incluye ponderacion y funciones beneficio falta de- sobre-representacion (numero localidades cada especie). Aplicamos metodo planificacion bosques ricos en hierbas sur Finlandia. Nuestro uso ponderaciones cambio identidad alrededor sitios seleccionados diferentes financiamiento mejoro raras amenazadas. Tambien identificamos pequena terreno adicional daria realce sustancial actual red Sugerimos se considere opciones estandar
