Enter the working forest: Discourse analysis in the Northern Forest

In 1988, four states in the northeastern USA commissioned a study to address land use changes in the Northern Forest, 26 million acres of temperate and boreal forest extending from Maine to eastern New York State. Against a backdrop of economic destabilization and concerns regarding social and ecological implications of a real estate boom, the sustained deliberative dialogue catalyzed by this s...

UAV LiDAR for below-canopy forest surveys

Remote sensing tools are increasingly being used to survey forest structure. Most current methods rely on GPS signals, which are available in above-canopy surveys or in below-canopy surveys of open forests, but may be absent in below-canopy environments of dense forests. We trialled a technology that facilitates mobile surveys in GPS-denied below-canopy forest environments. The platform consist...

Radiological surveys of working quarrymen and quarrying communities in Caernarvonshire.

Interest in the possible occupational lung diseases associated with slate-quarrying appears to date from the Registrar-General's Decennial Supplement, 1921, on Occupational Mortality (Registrar-General, 1927). Britten's review (Britten, 1928) showed that slate-masons and slate-workers had a significantly raised mortality from respiratory tuberculosis although it was much lower than that of tina...

Secondary forest: a working definition and typology

With past and continued destruction of primary forests worldwide, secondary forests constitute a large and growing component of forest cover and have been found to be very important for a wide range of goods and services.” There is considerable ambiguity with regard to the meaning of the term “secondary forest” and the different forest types it encompasses, despite its widespread usage. This pa...
