Description: Das Projekt "Satellitengestuetzte Umweltueberwachung europaeischer Waelder" wird vom Umweltbundesamt gefördert und von Universität Freiburg, Institut für Forstökonomie, Abteilung für Fernerkundung und Landschaftsinformationssysteme durchgeführt. General Information : The aim of this pilot project is to evaluate the cost-effectiveness of harmonised and demonstrated satellite based methods for assessment of disturbances in European forests. The methods are developed to enable The EC/DGVI customer on the European level, and Forest Administrations on national level, to conduct long-term monitoring of effects caused by air pollution, climatic stress, insect attacks, storm, and fire damage. The implementation of proposed methods aims firstly at evaluate the possibility to complement or partly replace field inventories in the Level I forest plots, set up by EU/DGVI in a 16 x 16km grid. From statistical aggregation of Level I plot results, NUTS regions where local, area-covering monitoring is of interest can be identified. Secondly, harmonised local monitoring methodology will be demonstrated to local and national Forest Administrations in provincial NUTS regions within the four major European forest ecosystem regions. Using this conceptual framework, a system is created that enables sample based monitoring at the European level to a reduced cost, that provides a statistical basis supporting decisions on where to apply local area-covering surveys, and includes harmonized methods for local surveys. Methods using Landsat TM and SPOT data for assessment of the environmental problems addressed; air pollution effects, climatic stress, insect attacks, storm and fire damage have been evaluated in earlier efforts. However, the methods used in different European regions and climate zones need harmonising. Analysis and compilation of obtainable accuracies for the different damage types as compared to end user requirements is also needed. The project includes a minor element of methodological development evaluating the possiblity to improve existing techniques by the use of new high resolution satellite data such as IRS-1C, MOMS, and ADEOS. To reach these general objectives, the project aims at the following measurable goals: - To compare and harmonise satellite techniques and classification systems used in the four major European forest ecosystem regions for defoliation and discoloration on assessable tree species, aiming at harmonised monitoring of the trans national Level I plot grid. To implement chosen techniques on Level I plots for two pilot satellite scenes in each of the four forest regions. - To determine how large a percentage of the Level I plots that will beasse ssable using satellite data with adequate accuracy, and to evaluate the cost-effectiveness of applied methods compared to the current field basea Level I inventory. - To demonstrate area-covering monitoring of the different damage types one demonstration area within each of the four major European forest ecosystem regions...
