Mercury (Hg) is an element of major concern in boreal freshwater ecosystems, due to high concentrations of Hg in fish. Forestry operations have been reported to increase the concentrations and loads of Hg to surface waters. In this thesis a series of catchment-scale experiments were used to determine forestry effects on total mercury (THg) and methyl mercury (MeHg) runoff concentrations caused ...

In agriculture and forestry, robotics has made a substantial impact. Farmers are conscious of their need for automatic vehicle guidance to minimize damage to the growing zone of their soil. Automatic sensing, handling, and processing of produce are now commonplace, while there is substantial instrumentation and mechanization of livestock procedures. In forestry, legged harvesters have not yet s...

Encouraging agricultural and forestry carbon sequestration and greenhouse gas mitigation is a necessary tool to meet U.S. emissions targets at minimum cost, but implementation challenges have relegated the agriculture and forestry sector to a marginal role in national and international cap-and-trade and energy policies, including those currently being discussed by U.S. legislators. However, the...

Ecological restoration is expected to reverse the loss of biodiversity and ecosystem services. Due to the low number of well-replicated field studies, the extent to which restoration recovers plant communities, and the factors underlying possible shortcomings, are not well understood even in medium term. We compared the plant community composition of 38 sites comprising pristine, forestry-drain...
