In WP 2 we will assess the impact of land use on forest area and forest structure. This is carried out on the basis of selected landscape cutouts and satellite images from WP 1. Data on carbon storage, biodiversity, tree composition, increment of commercial timber species and land use history will be collected. Primary and secondary forests, forest plantations and agroforestry plots will be assessed.
These data will allow concluding to which extent previous utilization was sustainable and is matching with economic, ecological and socio-economic requirements. We will analyze, whether today’s forest condition is the result of sustainable or unsustainable management and if agroforestry systems may be a viable option as alternative to agrarian and forest monocultures.
From these analyses we will derive recommendations for sustainable forest management and multifunctional forest landscapes. This will contribute to international forest policy issues which aim at forest protection through sustainable utilization of forest resources.
A stratification of satellite images according to fourforest strata (primary, secondary forest, forest plantation,agroforestry) will be implemented. Furtherstratification will be applied for
Field data collection will take place in a standardizedsample plot procedure as described by SYNNOTT(1979). Plot size will be 25 x 25 m. One quarterof all sample plots will be established aspermanent plots (size 100 x 100 m) where the incrementof all trees (> 25 cm dbh) will be measuredby increment tapes. A re-measurement after3 years will allow the calculation of increment anda comparison with the average annual cut. Thesample plots in forest plantations and agroforestrysystems will be smaller (10 x 10 m).
