As part of the intensive field campaign (IFC) for the Boreal forest ecosystematmosphere research (B OREAS) project in August 1993, the NASA/JPL AIRSAR covered an area of about 100 km x 100 km near the Prince Albert National Park in Saskatchewan, Canada. At the same time, ground-truth measurements were made in several stands which have been selected as the primary study sites. This paper focuses...
The reality of protected area management is that enforcing forest and park boundaries is costly and so most likely incomplete, due in part to the pressures exerted on the boundaries by local people who often have traditionally relied on the park resources. Buffer zones are increasingly being proposed and implemented to protect both forest resources and livelihoods. Developing a spatially-explic...

The largest pine forest on the North American Continent estends from north-central Arizona in a southeasterly direction into southwestern New Mexico, a distance of approsiinately 250 miles The forest occupies an extensive plateau, known as the Colorado Plateau, which has a general elevation of from 6,000 to 8,000 feet above sea level, with numerous peaks the highest of which reaches an altitude...
From 2000 to 2004, ticks were collected by dragging a blanket in four habitat areas in The Netherlands: dunes, heather, forest, and a city park. Tick densities were calculated, and infection with Borrelia burgdorferi and Anaplasma and Ehrlichia species was investigated by reverse line blot analysis. The lowest tick density was observed in the heather area (1 to 8/100 m2). In the oak forest and ...
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...
the objective of this research was to identify and describe the different ecological species groups (vegetation types) present in the rural heritage museum of guilan. the study area was approximately 260 ha, which is located in the saravan forest park in guilan province, north of iran. sampling procedure was performed with a systematic random technique. a total of 89 plots were sampled. classif...
Ethiopia harbours several relict populations of African wild dogs Lycaon pictus, but most data is anecdotal. Wild dogs are known to occur atypically in the montane wet forest of Harenna in the southern slopes of Bale Mountains National Park, southeastern Ethiopia. A questionnaire-survey of 90 Harenna forest residents investigated the local people’s knowledge and attitudes to wild dogs. Wild dog...
