OSPAR Beach Litter Monitoring in the Netherlands. Update 2024. Part II Applied Methods North Sea Foundation

Beach litter monitoring started as a programme commissioned by Rijkswaterstaat (RWS) in 2002. From 2000 till 2007 beach litter monitoring was part of a pilot project in 9 EU countries, it then transferred into a regular OSPAR monitoring programme.

From 2023 onwards, RWS's information needs and the beach litter monitoring results, for easy reading by a broader public, are described in the annual report part l: Status and Trends (Maas & Hougee, 2025). This report, the applied methods report, is designed for the specialistic reader. It provides an overview of all deviations and changes that have occurred in the applied methods (such as the software, survey sites) from the start of the beach litter monitoring programme to the last monitoring year.
