- W2004755566 abstract "Abstract: We used spatial and statistical analyses to identify and prioritize broad areas for conservation attention in the northern Zululand region of KwaZulu-Natal, South Africa. We attempted to identify conservation-worthy areas based on species, vegetation types, ecological processes, and threats to biodiversity. Information on species was limited and so could not form the basis of the analysis. Priority vegetation types were identified by degree of endemicity, extent of protection and transformation, and degree of fragmentation. These priority vegetation types and threats to biodiversity were used to define broad linkages between existing protected areas. We set a goal of 10% protection for each vegetation type and 25% for each species. We identified several important (endemic or threatened) animal species and predicted their ranges using a simple model. Species ranges and their hotspots were compared with the distribution of protected areas and the suggested linkages to evaluate increased species representation. Generally, the eastern part of the study area was well protected. Unprotected conservation-worthy areas under greatest threat lay in the west, and protecting these areas is a priority. Furthermore, several vegetation types were not protected by provincial authorities, a situation that also needs to be addressed. The findings of our study need to be reassessed at a finer land-parcel scale, and implementation of a range of land-use options considered. Resumen: Se utilizaron análisis espaciales y estadísticos para identificar y priorizar áreas amplias para conservación en la región Norte de Zululand en KwaZulu-Natal, Sudáfrica. Intentamos indentificar áreas meritorias de conservación en base a especies, tipos de vegetación, procesos ecológicos y amenazas a la biodiversidad. La información sobre las especies fué limitada y por lo tanto no pudo formar parte de las bases para el análisis. Los tipos de vegetación proritarios se identificaron usando el grado de endemismo, grado de protección, transformación y grado de fragmentación. Estos tipos prioritarios de vegetación y las amenazas a la biodiversidad fueron usados para definir conexiones amplias entre áreas protegidas existentes. Se estableció una meta de protección de un 10% para cada tipo de vegetación y de un 25% para cada especie. Varias especies importantes de animales (endémicas o amenazadas) fueron identificadas y se predijeron sus rangos utilizando un modelo simple. Se compararon los rangos de las especies y sus zonas de importancia con la distribución de áreas protegidas y las conexiones sugeridas para evaluar el incremento en las especies representadas. Generalmente la parte Este de la zona de estudio estuvo bien protegida. Las áreas desprotegidas meritorias de conservación y bajo la mayor amenaza se encuentran en el Oeste y la protección de estas áreas es prioritaria. Mas aún, varios tipos de vegetación no estaban protegidos por las autoridades provinciales, esto debe ser atendido también. Los resultados de nuestro estudio necesitan ser re-evaluados a una escala fina de parcela y será necesario considerar la implementación de un rango de opciones de uso del suelo." @default.
