Forests managed for timber have an important role to play in conserving global biodiversity. We evaluated the most common timber production systems worldwide in terms of their impact on local species richness by conducting a categorical meta-analysis. We reviewed 287 published studies containing 1008 comparisons of species richness in managed and unmanaged forests and derived management, taxon,...

Assessment of the ecological status of rivers is key to monitoring the achievement of the environmental goal of the EU Water Framework Directive and the success of restoration projects. In summer of 2009 and 2010, repeated assessments of physical habitat conditions and of fish and benthic invertebrate communities were performed at low-flow conditions in 10 unmanaged and 10 channelized cross-sec...

Calculating stand biomass potential is an increasingly important aspect of silviculture, particularly when attempting to restore forest ecosystems or determining additionality in sequestered carbon. However, the lumbering of the original forests of the Midsouth region of the United States of America, coupled with the accelerating conversion of unmanaged natural-origin stands to loblolly pine (P...

European beech plays a prominent role in the adaptation of forests to and mitigation climate change. Forest management may increase potential by accelerating carbon accumulation tree biomass, but little is known about interaction between rate biomass expansion its sensitivity variation or resistance extreme drought episodes. A 60-year thinning experiment Central Europe was used generate tree-ri...

Forests play an important role in climate change mitigation. Usage of harvested wood products (HWP) can extend the carbon cycle by retaining as well preventing new fossil emission via substitution. We compared balance different management strategies birch spruce mixed stands over eight-year period: unmanaged, representing a decision prolonged rotation, and managed, final harvest retention for c...

a r t i c l e i n f o Keywords: Ecosystem-based management Cultural capital Forest policy Silviculture Bureaucracy Forests in North America have been managed, or unmanaged, under a number of different policy regimes, most recently ecosystem-based management (EBM), which has emerged in response to perceived widespread ecological degradation. But as policy regimes shift, links between stated obje...

We used models to project forest carbon stocks for a series of harvesting scenarios 29 boreal management units totalling 23.3 million ha in Ontario, Canada. Scenarios evaluated 2020 2050 ranged from no option annual 2% the total merchantable volume present 2020. For each scenario, we estimated following quantities: (a) ecosystem stocks, (b) sum and harvested wood products (HWP) minus emissions ...

In asserting that the number of firms reporting small profits is abnormally high, thus suggesting that earnings management has taken place, accounting researchers assume that the distribution of reported earnings should be smooth for unmanaged earnings. This has never in fact been demonstrated. This article seeks to confirm this assumption through a laboratory experiment, and also sets out to i...
