At present Ecoauthor is working on the development of the National Benthos Indicator for evaluation of the Dutch North Sea for the Marine Strategy Framework Directive (MSFD) in cooperation with Wageningen Marine Research. 
The challenge is to develop a transparant indicator that will be used for various evaluations and reportings (e.g. MSFD, Habitat Directive, evaluation of Nature 2000 management and evaluation of effectivity of taken measures) that can act on the various spatial and temporal scales involved and will be indicative for causes of potentially observed changes as well. Yesterday we had some good discussions and valuable information exchange during an expert workshop as organized by the Ministry of Economic Affairs (EZ) and the Ministry of Infrastucture and the Environment (I&M) for which I like to thank all participants and the organizers.
