=====Logging by selective extraction of best trees: Does it change patterns of genetic diversity? The case of Nothofagus pumilio===== | |||
[https://www.sciencedirect.com/science/article/abs/pii/S0378112716301918 by Carolina Soliani 1/8/16 ScienceDirect] | |||
Extensive knowledge of the ecological and genetic consequences of implementing management practices (i.e. logging) in natural ecosystems is of fundamental importance to conservation action. Accordingly, characterization of forest genetic resources in managed vs non-managed stands may inform management decisions to ensure the long-term persistence of genetic diversity. | |||
=====Tree felling by beaver promotes regeneration in riparian woodlands whilst increasing resource availability for deer===== | |||
[https://www.sciencedirect.com/science/article/pii/S0378112724002226 by Kelsey A. Wilson 15/6/24 ScienceDirect] | |||
Interactions between species influence ecosystem functions and are sensitive to reintroductions. Our understanding of interactions between naturally co-occurring large herbivores, such as Eurasian beaver (Castor fiber) that are now re-establishing throughout their range, and well-established native ungulates, is limited, despite the potential implications for riparian woodlands. Observations in Scotland indicate that roe deer (Capreolus capreolus) readily exploit the regenerative secondary shoots produced after tree felling by beaver. | |||
=====Monitoring selective logging intensities in central Africa with sentinel-1: A canopy disturbance experiment===== | |||
[https://www.sciencedirect.com/science/article/pii/S0034425723003796 by Chloé Dupuis 1/12/23 ScienceDirect] | |||
Forest degradation is a major threat to tropical forests, and effective monitoring using remotely sensed data is subject to significant challenges. In particular, consistent methods for detecting subtle changes in the forest canopy structure caused by selective logging are lacking. Here, using a unique dataset collected in southeastern Cameroon, covering over 22,000 ha of monthly harvesting areas, >6000 locations of harvested trees, and an independent canopy gap dataset developed from an uninhabited aerial vehicle flight (UAV; RGB camera) of approximately 1500 ha, a new method was designed to monitor canopy disturbance and logging intensity in Central Africa. | |||
=====Tendency of wood fuels from whole trees, logging residues and roundwood to bridge over openings===== | |||
[https://www.sciencedirect.com/science/article/abs/pii/S0961953403001016 by Peter Daugbjerg Jensen 2/04 ScienceDirect] | |||
Solid biofuels such as wood chips are common fuels in many heating plants. The fuels are by nature heterogeneous and the fuel particles can form a stable structure across openings, which may stop the fuel flow in the feeding systems of heating plants. | |||
=====Fuel quality changes during seasonal storage of compacted logging residues and young trees===== | |||
[https://www.sciencedirect.com/science/article/abs/pii/S0961953407000219 by M. Pettersson 11/07 ScienceDirect] | |||
Forest fuel procurement creates logistical problems, as large stocks are accumulated along the supply chain. The purpose of this study was to examine fuel quality (moisture content, ash content and calorific value) of compacted young trees (mainly downy birch) and both uncompacted and compacted logging residues (LR) (mainly Norway spruce). | |||
=====Single-tree salvage logging as a response to Alaska yellow-cedar climate-induced mortality maintains ecological integrity with limited economic returns===== | |||
[https://www.sciencedirect.com/science/article/abs/pii/S0378112721009063 by Sarah M. Bisbing 1/1/22 ScienceDirect] | |||
Cost-benefit analyses of salvage logging have generally focused on large-scale, landscape disturbances salvaged at high intensity, and there is limited research on the ecological and economic outcomes of low-intensity salvage implemented for the benefit of forest-dependent communities. Here, we assess the potential impacts of small-scale, single-tree salvage logging of a foundation tree species (yellow-cedar, Callitropsis nootkatensis) on ecological integrity against the viability of salvaged wood as a source of timber for cultural and economic purposes. | |||
=====How do logging residues of different tree species affect soil N cycling after final felling?===== | |||
[https://www.sciencedirect.com/science/article/abs/pii/S0378112718305048 by Tiina Törmänen 1/11/18 SocialDirect] | |||
The aim of this study was to compare how logging residues of Norway spruce (Picea abies (L.) Karst.), Scots pine (Pinus sylvestris L.) and silver birch (Betula pendula Roth.) affect the dynamics of N and C cycling processes in forest soil after final felling. | |||

A quantitative analysis for Moabi (Baillonella toxisperma), Sapelli (Entandrophragma cylindricum) and Tali (Erythrophleum suaveolens) in Cameroon===== | =====Do logging concessions decrease the availability to villagers of foods from timber trees?

California Gold Rush history is the center of Coloma, California, where James W. Marshall discovered gold at Sutter’s Mill. The Marshall Gold Discovery State Historic Park has a great museum, outdoor exhibits, gold panning lessons, tours, and living history days on the second Saturday of the month. | California Gold Rush history is the center of Coloma, California, where James W.
