Aerial surveys

Sweden has the highest variation in wetland types within the EU, and after Russia, it has the largest wetland area in Europe. The Swedish Wetland Survey (VMI), which covered all large wetland sites except the ones in the alpine zone, took place between 1981 and 2004. The purpose of this report is to make information about the wetland survey available outside of Sweden. The report is a compilation of excerpts from the national final report. It focuses on VMI-methodology, Swedish wetland types, and the results and the final evaluation of the survey.
