Ongoing monitoring and exchange of experience

Evaluation and long-term monitoring are required to ensure that the Green Belt develops as desired and that the many management measures are successful. Also, provision must be made for monitoring the conservation status of former federal National Natural Heritage land that has been transferred to the Länder and their nature conservation foundations. 

Implementation of a monitoring system

A variety of evaluation and monitoring approaches were presented at a congress on management of the Green Belt in 2011. Participants were unanimous that the use of comparable monitoring methods and uniform management of data on the Green Belt would be helpful and should be implemented where possible.

Assessments of the biotope types of a part of the Green Belt between Buttlar and Grüsselbach in Thuringia made in the year 2001 and in 2012.
There are two assessments of the biotope types of a part of the Green Belt between Buttlar and Grüsselbach in Thuringia. One made in the year 2001 and the other in 2012. 4.4 ha have been converted from arable farm land to extensive grassland.

In an R&D project on updating the Green Belt inventory, current inventory data was compiled as a basis for long-term monitoring, and a monitoring approach was developed and coordinated with key players and Green Belt landowners. The monitoring approach applies the methodology used for the 2012 inventory and involves a 12-year cycle with an aerial survey followed by interpretation of the imagery after the first six years and a ground-based survey mapping all habitat types in the Green Belt after the second six years.

Exchange of experience

The special nature of the Green Belt means that similar problems are faced in the various regions it traverses. Regular exchange of experience between those involved in protecting the Green Belt is important in addressing these problems. Conferences are held for this purpose every two years. The most recent conference was organised by the Thuringia conservation organisation Stiftung Naturschutz Thüringen in 2013.
