Overview
The use of total area protected as the predominant indicator of progress in building protected area (PA) networks is receiving growing criticism. Documenting the full dynamics of PA networks, both in terms of the gains and losses in protection, provides a much more informative approach to tracking progress. To this end, documentation of PA downgrading, downsizing, and degazettement (PADDD) has increased. Studies of PADDD events generally fail to place these losses in the context of gains in protection; therefore, they omit important elements of PA network dynamics. To address this limitation, we used a spatially explicit approach to identify every parcel of land added to and excised from the Australian terrestrial PA network and PAs that had their level of protection changed over 17 years (1997-2014). By quantifying changes in the spatial configuration of the PA network with time-series data (spatial layers for nine separate time steps), ours is the first assessment of the dynamics (increases and decreases in area and level of protection) of a PA network and the first comprehensive assessment of PADDD in a developed country. We found that the Australian network was highly dynamic; there were 5233 changes in area or level of protection over 17 years. Against a background of enormous increases in area protected, we identified over 1500 PADDD events, which affected over one-third of the network, which were largely the result of widespread downgrading of protection. We believe our approach provides a mechanism for robust tracking of trends in the world's PAs through the use of data from the World Database on Protected Areas. However, this will require greater transparency and improved data standards in reporting changes to PAs. El uso del área total protegida como indicador predominante del progreso en la construcción de redes de áreas protegidas (AP) cada vez recibe más críticas. La documentación de las dinámicas completas de las redes de AP, tanto en términos de ganancia y pérdida de protección, proporciona una estrategia mucho más informativa al seguimiento del progreso. Para este fin, la documentación de la degradación, reducción y pérdida de protección legal (PADDD, en inglés) de las áreas protegidas ha incrementado. Los estudios de eventos de PADDD generalmente fallan en ubicar estas pérdidas en el contexto de la ganancia de protección, por lo que omiten elementos importantes de dinámicas de redes de AP. Para enfocarnos en esta limitación utilizamos una estrategia espacialmente explícita para identificar cada lote de suelo añadido y extirpado de la red australiana de AP terrestres y las AP que sufrieron un cambio en su nivel de protección durante 17 años (1997 - 2014). Con la cuantificación de los cambios en la configuración espacial de la red de AP con datos de series de tiempo (capas espaciales para nueve pasos temporales separados), realizamos la primera valoración de las dinámicas (incrementos y decrementos en el área y en el nivel de protección) de una red de AP y la primera valoración comprensiva del PADDD en un país desarrollado. Encontramos que la red australiana era altamente dinámica: hubo 5, 233 cambios en el área o en el nivel de protección durante 17 años. Frente a un fondo de incrementos enormes en el área protegida, identificamos más de 1, 500 eventos de PADDD, los cuales afectaron más de un tercio de la red y que eran en general el resultado de una degradación extensiva de la protección. Creemos que nuestra estrategia proporciona un mecanismo para el seguimiento convincente de las tendencias de las AP mundiales con el uso de datos de la Base de Datos Mundial de Áreas Protegidas. Sin embargo, esto requerirá de mayor transparencia y estándares de datos mejorados en el reporte de los cambios en las AP.
