The Bavarian Forest National Park, established in 1970, is a unique area of forests with large nonintervention zones, which promote a large-scale rewilding process with low human interference. Thus, the National Park authority is particularly interested in investigating the structure and dynamics of the forest ecosystems within the park. However, conventional forest inventories are timeconsumin...

This paper investigates the potential of laser scanning data to model forest 3d structure and its spatial pattern. Most of the existing methods for assessing structures in mountain forests are either inventory methods, which cannot be used for spatial assessments over large areas, or methods aimed only at assessing actual wood production. Several new landscape metrics are developed and applied ...

We describe the temporal and geographical distribution of confirmed cases of bovine tuberculosis (TB) in a population of cattle in the south-east of the North Island of New Zealand. Data were derived from routine TB testing conducted between 1980 and 2003 and included details for 69 farms. Four six-year periods were defined to coincide with changes in depopulation strategies against the wildlif...

Study sites The study sites were located along the northeast shore of Lake Tanganyika providing an ideal comparison between forested and deforested watersheds. Seven contrasting streams were studied; four of these streams were located in forested watersheds within the Gombe Stream National Park. Vegetation in Gombe Stream National Park consists of semi-deciduous woodland, wetter canopy forests ...
