THE STATE OF AGRO-BIODIVERSITY IN THE NETHERLANDS INTEGRATING HABITAT AND SPECIES INDICATORS

摘要

This assessment deals with wild-living species in agricultural ecosystems at the national level. It focuses on the loss of biodiversity since 1950 when most modern intensive agricultural management practices were introduced. It builds further on species and habitat indicators discussed in the CBD (1997) and OECD (2001). This paper has been produced by the RIVM and is based on information of i) the Central Statistical Office (CBS) and Alterra; ii) various organisations monitoring plant, reptile, bird,mammal, fish, butterfly and aquatic macro fauna species; iii) research institutes and universities which carried out research on baseline values (Flordh, 1997; Ravon, 1999; Kleunen, 2001; Kleunen en Sierdsema, 2001; IWACO, 2001; Vlinderstichting, 1999;Hollander, 2000).
