Effects of atmospheric deposition on natural areas can be mitigated by management. For example, the effects of excessive nitrogen deposition can partly be overcome by intensifying measures like mowing or sod cutting. The costs of this extra management may, in the future, no longer be required when d
Question: The use of expert-based indicator values to estimate abiotic conditions from vegetation is widespread. However, recent research has shown that expert judgement may contain considerable bias and thereby introduces a large amount of uncertainty. Could expert based indicator values be replace
Smart & Scott (2004, this issue) criticized our paper (Wamelink et al. 2002) about the bias in average Ellenberg indicator values. Their main criticism concerns the method we used, regression analysis. They state the bias can be mimicked by the construction of an artificial data set and that regress
Bij het voorspellen van effecten van ingrepen op vegetaties wordt vaak uitgegaan van indicatiesystemen gebasseerd op standplaatscondities. Een andere benadering is het voorspellen van voorkomen van soorten op basis van functionele eigenschappen. In populatie-ecologisch onderzoek gericht op successie
Alterra was commissioned by the Dutch Ministry of Housing, Spatial Planning and the Environment (VROM) to estimate the additional costs made by nature reserve managers to mitigate the effects of atmospheric deposition. The costs of increasing deposition levels - or the benefits of reducing depositio
In dit rapport wordt de ruimtelijke vergelijking van, door SUMO gesimuleerde bladbiomassa, met de via remote sensing verkregen NDVI beschreven. Vergelijking heeft plaats gevonden voor meer dan 90% met vegetatiestructuurtypen gevulde SUMO grids (250m*250m) binnen de EHS. De gevonden relaties voor ver
