Angewandte Fernerkundung: Moderate Resolution Imaging Spectroradiometer (MODIS)
|
In diesem Projekt werden verschiedene MODIS-Datensätze auf ihre Brauchbarkeit getestet. Wissenschafter vergleichen angebotene Fertigprodukte mit bestehenden Waldinventurdaten und CORINE-Daten. Für Snowcover-Untersuchungen verwenden sie Original-Spektraldaten. MODIS steht für "Moderate Resolution Imaging Spectroradiometer".

Waldweide - eine umstrittene Waldnutzung
|
In den Alpen hat die land- und forstwirtschaftliche Doppelnutzung von Waldflächen Tradition. Laut Forstgesetz gilt die Waldbeweidung aber als nachteilige Nutzung, weil sie die Holzqualität, Stabilität und Verjüngung des Gebirgswaldes negativ beeinflusst. Wie schädlich ist die Beweidung für den Wald tatsächlich?

Comparison of methods for interpolating soil properties using limited data
|
Spatial interpolation of biological and biophysical variables is of central interest to many landscape ecologists. In this study, scientists evaluated the utility, accuracy, and effectiveness of ordinary kriging, inverse-distance weighting, and thin-plate smoothing splines with tensions using soil samples from the Omo Basin, Ethiopia.

Spatially-explicit modelling of biophysical parameters for the Shoshone National Forest, WY
|
High resolution climate maps were generated for NW-Wyoming (USA) in order to measure tree species realized niches. The goal of this study was to define species parameters for a spatially-explicit, dynamic forest simulation model.

Developing a physiologically mechanistic tree migration model and simulating Holocene spread of forest trees
|
The potential of plants to migrate to habitats which are more favourable under changed conditions plays a key role in assessing the impacts of climate change on terrestrial ecosystems. A new, spatially explicit, physiologically mechanistic, and efficient forest succession model was developed in order to study the potential of trees to invade, migrate and get extinct under current and possibly changed future climate.

Emerging and Contemporary Technologies in Remote Sensing for Ecosystem Assessment and Change Detection on Military Reservations
|
The main objectives of this project were to stratify the landscape of individual military ranges, to identify the fundamental vegetation and soil attributes, to establish ecosystem response and recovery in relation to disturbance (land use), to identify the attributes of remote sensing systems and to develop methods for scaling indices between coarse and fine resolution imagery.

Predicting the distribution and dynamics of forest vegetation in the central Rocky Mountains: leaf area, sapwood, and site water balance at the tree, stand, and landscape level
|
Forests of the Central Rocky Mountains are of value for nature conservation and biodiversity maintenance. Developing a spatially explicit forest succession model upon a sound physiological basis is important to assist management and to further science of these crucial forests.

Streunutzung – ein Experiment
|
Noch vor 150 Jahren waren die Wälder stark durch agrarische Nutzungsweisen geprägt. Dazu gehörte neben der Waldweide auch die Nutzung der Waldstreue. Durch experimentelle Streunutzung wollen Wissenschafter herausfinden, welche Bedeutung diese Nutzungsweise für die heutigen Naturschutzmassnahmen im Wald haben könnte.

Linking dendrochronology with ecophysiology: The influence of water stress on cambial activity
|
In a changing environment, the analysis of how forest ecosystems may react under scenarios involving changing climatic conditions is of major importance. This project wants to evaluate the influence of expected climatic changes (precepitation and temperature regimes) on trees and the state of our forests.
