The distribution and abundance of non-human primates in Bangladesh is presented. Roadside and forest surveys were conducted throughout the alluvial floodplains and hill regions ofSylhet, Chittagong, and Cox's Bazar. In forests, walking and vehicle transects were used to census primates. The ecology and status of major habitat types are discussed. Forest primate populations are evaluated accordi...

—Satellite remote sensing is being used operationally by Swedish authorities in applications involving, for example, change detection of clear felled areas, use of k-Nearest Neighbour estimates of forest parameters, and post-stratification (in combination with National Forest Inventory plots). For forest management planning of estates, aerial photointerpretation in combination with stand-wise f...

In recent years, a remarkably simple physical picture of the Lyman-alpha forest has emerged, which allows detailed predictions to be made and turns the forest into a powerful probe of cosmology. We point out ways in which such a picture can be tested observationally, and explore three areas in which the Lyman-alpha forest can yield valuable constraints: the reionization history, the primordial ...

We investigated Marbled Murrelet (Brachyramphus marmoratus) habitatuse patterns by censusing a variety of forest stands at Redwood Experimental Forest in northwestern California. Murrelet activity levels were greatest 30 minutes before to 30 minutes after sunrise in May, June, and July. Surveys at fixed stations showed that during the breeding season, murrelets were present more often in old-gr...

In the early 1980s, deterioration in the crown condition of trees across many regions of Europe raised concerns over the health of European forests, and many countries established surveys to monitor this. In Britain, the Forest Condition Survey was instigated in 1984 (Binns et al., 1985) with an annual assessment of tree crown density on between 300 and 400 plots of five widely planted forest t...

This paper presents some issues related to designing forest landscape located close to the areas of watercourses and water reservoirs. Surface waters, beside forests and diverse terrain relief, constitute the main element deciding about tourist and recreation attractiveness of every such area. Some surveys on the evaluation of forest recreational potential prove that the forest attractiveness i...

A map of the native vegetation remaining in São Carlos County was built based on aerial images, satellite images, and field observations, and a projection of the probable original vegetation was made by checking it against soil and relief surveys. The existing vegetation is very fragmented and improverished, consisting predominantly of cerrados (savanna vegetation of various physiognomies), sem...
