Predicting the provisioning potential of forest ecosystem.services using airborne laser scanning data and forest resource m.ps

Background: Rem.te sensing-based m.pping of forest Ecosystem.Service(ES) indicators has becom. increasingly popular. The resulting m.ps m.y enable to spatially assess the provisioning potential of ESs and prioritize the land use in subsequent decision analyses. However, the m.pping is often based on readily available data, such as land cover m.ps and other publicly available databases, and ignoring the related ***: This study tested the potential to im.rove the robustness of the decisions by m.ans of local m.del fitting and uncertainty analysis. The quality of forest land use prioritization was evaluated under two different decision support m.dels: either using the developed m.dels determ.nistically or in corporation with the uncertainties of the ***: Prediction m.dels based on Airborne Laser Scanning(ALS) data explained the variation in proxies of the suitability of forest plots for m.intaining biodiversity, producing tim.er, storing carbon, or providing recreational uses(berry picking and visual am.nity) with Rm.Es of 15%–30%, depending on the ES. The Rm.Es of the ALS-based predictions were 47%–97%of those derived from.forest resource m.ps with a sim.lar resolution. Due to applying a sim.lar field calibration step on both of the data sources, the difference can be attributed to the better ability of ALS to explain the variation in the ES ***: Despite the different accuracies, proxy values predicted by both the data sources could be used for a pixel-based prioritization of land use at a resolution of 250 m.2, i.e., in a considerably m.re detailed scale than required by current operational forest m.nagem.nt. The uncertainty analysis indicated that m.ps of the ES provisioning potential should be prepared separately based on expected and extrem. outcom.s of the ES proxy m.dels to fully describe the production possibilities of the landscape under the uncertainties in the m.dels.
