It is important to have good information on the condition of the trees in the plots. Therefore scientists determine the relationships between crown condition and a number of environmental parameters.
lution (250m) soil information. Nevertheless, globally available soil maps can provide important predictors if no high-resolution soil maps are available. Moreover, among the tested soil predictors, pH [...] models based on measured soil properties with those based on digitally mapped soil properties at different spatial resolutions (25m and 250m). We first calibrated SDMs with measured soil data and plant species [...] we developed models using the same soil predictors, but extracted from digital soil maps at the nearest neighboring plots of the Swiss National Forestry Inventory. Our approach enabled a comprehensive

gradients of soil properties and six were not. For each species, two SDMs were created for the entire forested area of Switzerland: one without soil data and one with soil data. The models without soil data included [...] land-surface parameters, models with soil data additionally included soil parameters. The models were created with an ensemble of various model algorithms. The impact of soil data was tested with a mixed-effect [...] the considerable added value of soil data to SDMs of certain species. The distribution maps of models with soil data accounted for the small-scale variability of soil properties within the Swiss forested

2017 Christoph Fischer - Defining near-optimal harvesting techniques using Swiss National Forest Inventory data In Switzerland, the competitiveness of the Swiss forestry sector is currently under discussion [...] the application of up-to-date harvesting and transportation techniques The Swiss National Forest Inventory (NFI) delivers a wide range of information on forests using a combination of field assessments and [...] such as buffers. However, these methods do not take into account the heterogeneity of the terrain or soil properties. Moreover, because both the hauling of wood to a nearby road and the on-road transport
Establishing an inventory of soil water availability to trees in Swiss forest soils. This is done by means of model-based analysis of the water balances at 16 long-term monitoring sites in Switzerland, representing various geographical locations, soil and vegetation types.
