Description

This dataset was used as base data in Reefs at Risk.

Map of blast and poison fishing (1 km grid) was developed for use in the Reefs at Risk Revisited project as a component of the model of overfishing and destructive fishing pressure on coral reefs. This layer designates threat of blast and poison fishing based on the frequency of the activity. Moderate (or medium) threat indicates areas where destructive fishing occurs occasionally (i.e., a monthly basis), while severe (or high) threat indicates areas where destructive fishing occurs weekly or more frequently. Areas classified as low threat have infrequent or no known blast or poison fishing.

Compiled at the World Resources Institute from various sources including ReefCheck survey data (2009), the Tanzania Dynamite Fishing Monitoring Network (2009), and expert opinion from reef managers and local organizations.
