RAVON (NL) - Network Ecological Monitoring Reptiles

The Dutch reptile populations are being monitored intensively within the scope of the Dutch Network Ecological Monitoring (NEM). Since 1994 volunteers, coordinated by RAVON (Reptile, Amphibian and Fish Conservation Netherlands), monitor reptiles on an annual base. All seven indigenous species are monitored on transects that are examined seven times a year. The data are used to monitor population trends and patterns and to support legal reporting obligations, scientific research and policy and conservation related issues. Locality data for GBIF are provided on a 5 x 5 km scale.
