This dataset contains mapped point locations for protected areas within the Kingdom of Tonga. This dataset should be viewed in combination with the World Database on Protected Areas polygon locations to get a comprehensive view of all protected areas within Tonga.

Date produced by The Institute for Marine Remote Sensing (IMaRS) at the University of South Florida (USF) was funded by the Oceanography Program of the National Aeronautics and Space Administration (NASA) to provide an exhaustive worldwide inventory of coral reefs using high-resolution satellite imagery.

Metadata file for the GIS data (raster and shapefiles) for the global threats to coral reefs: acidification, future thermal stress, integrated future threats, and past thermal stress.

Metadata file for the GIS data (raster and shapefiles) for the local threats to coral reefs: coastal development, integrated local, marine pollution, overfishing, and watershed pollution.

This excel file include four spreadsheets each representing a separate theme (EMG = Environmental Monitoring and Governance, IOE = Island and Ocean Ecosystems, CCR = Climate Change Resilience, WMPC = waste). Within each theme are the core national environment indicators (scrolling from left to right).

Most atoll ecosystems and a wide range of terrestrial and marine organisms, and genetic or cultivars varieties of
traditional food and other multi-purpose plants are declining in abundance and under threat of either “economic extinction” or extirpation and in need of some form of protection. The severity of the situation is greatest on those more urbanized atolls where both the biodiversity and the local knowledge of biodiversity are threatened.

Reefs at Risk Revisited is a high-resolution update of the original global analysis, Reefs at Risk: A Map-Based Indicator of Threats to the World’s Coral Reefs. Reefs at Risk Revisited uses a global map of coral reefs at 500-m resolution, which is 64 times more detailed than the 4-km resolution map used in the 1998 analysis, and benefits from improvements in many global data sets used to evaluate threats to reefs (most threat data are at 1 km resolution, which is 16 times more detailed than those used in the 1998 analysis).
