We critically review recent literature on carbon storage and fluxes within natural and constructed freshwater wetlands, and specifically address concerns of readers working in applied science and engineering. Our purpose is to review and assess the distribution and conversion of carbon in the water environment, particularly within wetland systems. A key aim(More)
This review paper summarises the environmental effects of runoff from wood handling sites including log yards. The characteristics of site runoff and the corresponding effects on the receiving watercourses are presented for worldwide case studies, highlighting the urgent need to address the water pollution problem associated with the wood industry.

Hurricanes pose a great risk to forestry, and lead to high financial losses due to destroyed wood. For example, the hurricane ‘‘Gudrun’’ devastated a large part of the forests of southern Sweden in January 2005. Windthrown logs are removed from forest, temporarily stored on log yards, and frequently sprinkled with water to avoid decay. However, the(More)
Treatment of log yard runoff is required to avoid contamination of receiving watercourses. The research aim was to assess if infiltration of log yard runoff through planted soil systems is successful and if different plant species affect the treatment performance at a field-scale experimental site in Sweden (2005 to 2007). Contaminated runoff from the log(More)
