For metrics, such as extent of protected areas, to inform global conservation efforts, the data sets on which the metrics are based must be comparable. The World Database on Protected Areas (WDPA) is the most comprehensive set of spatial data available on marine and terrestrial protected areas worldwide. The United Nations Environment Programme’s World Conservation Monitoring Centre (UNEP-WCMC) has compiled and updated these data yearly since 1981. These annual releases serve the global… 

A gap analysis comparing the effectiveness of Natura 2000 and national protected area networks in representing European amphibians and reptiles

Protected area networks represent one of the mainstays of worldwide conservation policies and play a key role in the protection of biodiversity. While numerous studies have evaluated the extent to

Analysis of change in the distances between global terrestrial protected areas and urban areas

With the expansion of urban areas and protected areas (PAs), the distance between them is strongly declining. However, this phenomenon hasn't garnered much attention. The negative influences of urban

Philippine protected areas are not meeting the biodiversity coverage and management effectiveness requirements of Aichi Target 11

For the Philippines to meet the biodiversity coverage and management effectiveness elements of Aichi Target 11, protected area and KBA boundaries should be aligned, management systems reformed to pursue biodiversity-led targets and effective management capacity created.

Using a bird community index to evaluate national parks in the urbanized national capital region

Land managers and conservationists face two challenges in protecting land: first balancing human needs against conservation goals, and second demonstrating protected areas are meeting those goals. In

Effectiveness of China's nature reserves in representing ecological diversity

Mainland China has 2538 nature reserves, covering approximately 15% of its total land area. However, little is known of their effectiveness in capturing the country's ecological diversity. We

Hot moments for biodiversity conservation

Biodiversity conservation requires prioritization to be effective. Biodiversity hotspots and conservation planning identify where to focus conservation efforts, but it is unclear when conservation is

Assessment of the network of protected areas for birds in Taiwan with regard to functional and phylogenetic diversity

The spatial distribution of bird assemblages in Taiwan was explored, and it was found that phylogenetically close birds have similar trait values, and the protected species were evenly distributed in the functional and phylogenetic trees.

Spatial and temporal variations of habitat in typical nature reserves, china

Based on remote sensing inversion, model simulation and spatial analysis methods, spatial and temporal variations of habitat from the vegetation fraction, net primary production, and their driving forces in different types and clime zones on the typical national nature reserves of China in the first 15 years of the 21st Century are analyzed.

Measuring the extent and effectiveness of protected areas as an indicator for meeting global biodiversity targets

The role of the World Database on Protected Areas and collection and quality control issues are discussed, and areas for improvement are identified, including how conservation effectiveness indicators may be included in the database to improve the value of protected areas data as an indicator for meeting global biodiversity targets.

Revisiting Extinction in National Parks: Mountain Caribou in Banff

The controversial question Berger (2003) raised about whether it is acceptable to let a species go extinct in a national park is revisited and the policy and scientific processes that have driven this species to extinction in Canada's oldest and flagship national park are reviewed.

Canada's Species at Risk Act

Only the Atlantic salmon is currently listed under the Species at Risk Act; Cabinet decided not to list the two sockeye after considering socioeconomic implications and decisions on listing coho and Chinook are pending socioeconomic assessment.

Is It Acceptable to Let a Species Go Extinct in a National Park?

I once was asked whether it was okay to allow a species to go extinct in a national park. My gut response was no, but I had not thought about the question seriously: whose park and where, and would
