Evaluation of the multicriteria approval method for timber-harvesting group decision support

Silva Fennica, 2005
The decision support methods most often used in timber-harvesting planning are based on a single criterion. In this study, a voting-theory-based method called multicriteria approval (MA) is introduced to the group decision support of timber-harvesting.

Impact of forest biomass for energy harvesting on soil compaction - Irish case study

Journal of Forest Science, 2014
An assessment of soil compaction caused by machinery used in stump and/or logging residue extraction for energy on soils typical of Ireland. We determined unaffected soil conditions and to find the compaction grade after timber harvesting and bundling ...

The Effect of Timber Harvesting on Fluctuation of Peat Water Level and Subsidence of Peat-Soil Surface

Journal of Wetlands Environmental Management, 2018
A goal of timber harvesting is to increase timber production through removing the timber  from the forest using some harvesting techniques.  A peatland is a fragile ecosystem and may degraded easily.

Successful and unsuccessful attempts to resolve caribou management and timber harvesting issues in west central Alberta

Rangifer, 1996
Research studies of woodland caribou in west central Alberta began in 1979 in response to proposed timber harvesting on their winter ranges. Using results from initial studies, timber harvest guidelines were developed. A recent review of these guidelines,

Modifying harvesting time as a tool to reduce nutrient export by timber extraction: a case study in planted teak (Tectona grandis L.f.) forests in Costa Rica

iForest - Biogeosciences and Forestry, 2016
Despite its low nutrient concentration, the high amount of biomass accumulated in the tree stem makes it an important nutrient sink. Hence, nutrient loss through timber removal at harvesting is a major cause of nutrient impoverishment at some forest ...
