Spatially explicit database of tree related microhabitats (TreMs). Version 1.2. Integrate+ project

nitially the permanent plots established within the Integrate+ project had the focus on showing good practice examples of integrative forest management concepts. The plots were designed following the Marteloscope approach to allow practitioners to perform virtual tree selection exercises in the demonstration sites based on different scenarios and forest management strategies. Immediate feedback on their decisions is given in terms of ecological and economic impacts. Particular attention was given to tree related microhabitats as these structures are home to many, also endangered species. Retaining and restoring such habitats in managed forests can be well integrated into the work portfolio of forest managers and thus be a direct contribution to biodiversity conservation in managed forests. The TreM recording and the development of the field catalogue was primarily aimed at providing individual habitat values for each tree to make harvesting impacts visible to practitioners in Marteloscope exercises. In the course of the project the plots themselves proved valuable as exploratory forests for other research questions as well. In particular, the database with the spatially explicit information on trees and TreMs looked promising to increase understanding of TreM formation and development, and also spatial distribution
