+=====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.
+=====Do logging concessions decrease the availability to villagers of foods from timber trees? A quantitative analysis for Moabi (Baillonella toxisperma), Sapelli (Entandrophragma cylindricum) and Tali (Erythrophleum suaveolens) in Cameroon=====
+[https://www.sciencedirect.com/science/article/pii/S0378112716306636 by1/12/16 ScienceDirect]
+ Many species of timber trees in Cameroon are exploited by logging companies for timber and by forest-dependent communities for non-timber forest products (NTFPs). Quantitative analyses were conducted within and near forest concessions in Cameroon to determine the density of multiple use tree species that provide both timber for industry and foods consumed by local populations (fruit and oil or edible caterpillars), and how this has been affected by logging. Individuals of the three species (Moabi, Baillonella toxisperma; Sapelli, Entandrophragma cylindricum; and Tali, Erythrophleum suaveolens),
+=====Land tenure, logging rights, and tree planting: Empirical evidence from smallholders in China=====
+[https://www.sciencedirect.com/science/article/abs/pii/S1043951X18301111 by Ying Lin 4/20 ScienceDirect]
+ To encourage afforestation and promote rural livelihood, China launched a new round of forest tenure reforms (CFTR) for its collective forestland in 2003. Using data spanning a long time period for rural smallholders in China, this study analyzes the causal effects of land tenure security and logging rights on tree planting investments.
+=====Deforestation and Forest Loss=====
+[https://ourworldindata.org/deforestation by Hannah Ritchie 2/21 Our World in Data]
+ Before we look specifically at trends in deforestation across the world, it's useful to understand the net change in forest cover. The net change in forest cover measures any gains in forest cover — either through natural forest expansion or afforestation through tree planting — minus deforestation.
+=====Tree species richness and the logging of natural forests: A meta-analysis=====
+[https://www.sciencedirect.com/science/article/abs/pii/S0378112712001958 by Jason A. Clark 15/7/12 ScienceDirect]
+ Forests cover much of the earth’s surface and are regularly logged. Well established ecological theory predicts, and the results of extensive silvicultural studies demonstrate the role of disturbance in maintaining species richness in forests; however, logging and other human initiated disturbance is often credited with the degradation of forest
+=====Applying ecological knowledge to decisions about seed tree retention in selective logging in tropical forests=====
+[https://www.sciencedirect.com/science/article/abs/pii/S0378112708002223 by Joberto Veloso de Freitas 20/9/08 ScienceDirect]
+ In production forests in the moist tropics, trees are selected for felling or retention primarily by species and size. Tree regeneration requirements and forest stand responses to harvesting are often ignored, and consequently, the regeneration of the residual forest is not ensured. We developed and tested an alternative approach to tree selection, where seed trees were retained as a proportion of harvestable trees, with the proportion defined as a function of species’ ecological attributes and local abundance (100 ha), in contrast to the conventional approach which retained 10% of harvestable trees, uniformly across commercial species at the compartmental scale (1000 ha).
+=====Safeguarding villagers’ access to foods from timber trees: Insights for policy from an inhabited logging concession in Gabon=====
+[https://www.sciencedirect.com/science/article/pii/S235198941830177X by Hermann Taedoumg 6/18 ScienceDirect]
+ This study assessed the abundance of and access to tree species (Ozigo, Dacryodes buettneri; and Abam, Gambeya lacourtiana) that yield edible fruits to villagers and timber to the logging industry in and around a logging concession in Gabon. Participatory mapping combining GPS coordinates and interviews was carried out with 5 female and 5 male collectors in each of two villages within or adjacent to the logging concession.
+=====Recruitment, growth and recovery of commercial tree species over 30 years following logging and thinning in a tropical rain forest=====
+[https://www.sciencedirect.com/science/article/abs/pii/S0378112716304935 by Angela Luciana de Avila 1/2/17 ScienceDirect]
+ Sustainable production of timber from commercial species across felling cycles is a core challenge for tropical silviculture. In this study, we analysed how the intensity and type (harvesting and thinning) of silvicultural interventions affect: (a) recruitment of small stems (5 cm ⩽ DBH < 15 cm), (b) increment of future crop trees (15 cm ⩽ DBH < 50 cm) and (c) recovery of harvestable growing stocks (DBH ⩾ 50 cm) of 52 commercial timber species in the Tapajós National Forest, Brazil.
+=====Resprouting trees drive understory vegetation dynamics following logging in a temperate forest=====
+[https://www.nature.com/articles/s41598-020-65367-5 by Radim Matula 8/6/20 Scientific reports]
+ Removal of canopy trees by logging causes shifts in herbaceous diversity and increases invasibility of the forest understory. However, disturbed (cut) trees of many species do not die but resprout from remaining parts. Because sprouts develop vigorously immediately after disturbances, we hypothesized that sprouts of logged trees offset the changes in species richness and invasibility of the herbaceous layer by eliminating the rise in the resource availability during the time before regeneration from seeds develops.
+=====When big trees fall: Damage and carbon export by reduced impact logging in southern Amazonia=====
+[https://www.sciencedirect.com/science/article/abs/pii/S0378112705005232 by Ted R. Feldpausch  25/11/05 ScienceDirect]
+ We examined carbon export in whole logs and carbon accumulation as coarse woody debris (CWD) produced from forest damage during all phases of the first and second year of a certified reduced impact logging (RIL) timber harvest in southern Amazonia.
+=====Empirical relationships between tree fall and landscape-level amounts of logging and fire=====
+[https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0193132 by David B. Lindenmayer 23/2/18 PLOS one]
+ Large old trees are critically important keystone structures in forest ecosystems globally. Populations of these trees are also in rapid decline in many forest ecosystems, making it important to quantify the factors that influence their dynamics at different spatial scales.
+=====Large trees as key elements of carbon storage and dynamics after selective logging in the Eastern Amazon=====
+[https://www.sciencedirect.com/science/article/abs/pii/S0378112714000073 by Plinio Sist  15/4/14 ScienceDirect]
+ The long term effect of Reduced-Impact Logging (RIL) on above-ground live biomass (AGB) dynamics was investigated in 18 1-ha logged over permanent sample plots set up in a terra firme rain forest in the Eastern Amazon (Brazil, Paragominas).
+=====Effects of 50 years of selective logging on demography of trees in a Malaysian lowland forest=====
+[https://www.sciencedirect.com/science/article/abs/pii/S0378112713005999 by Toshihiro Yamada  15/12/13 ScienceDirect]
+ Species specific tree performance (growth, mortality, and recruitment rates) and population growth rate in a logged forest that was selectively logged in 1958 were compared with those in a primary forest using 10-year forest demographic data (1998–2008) in the Pasoh Forest Reserve in Malaysia.
+=====Potential losses of animal-dispersed trees due to selective logging in Amazonian forest concessions=====
+[https://www.sciencedirect.com/science/article/pii/S2666719322001236 by Elildo A.R. Carvalho Jr  9/22 ScienceDirect]
+ Fruits and seeds are key food resources for most Amazonian mammals and birds. Selective logging is an increasingly dominant land use in the region that can deplete these resources over large areas.
+=====Species grouping and diameter growth of trees in the Eastern Amazon: Influence of environmental factors after reduced-impact logging=====
+[https://www.sciencedirect.com/science/article/pii/S0378112724007771 by Jorge Luis Reategui-Betancourt 15/2/25 ScienceDirect]
+ Tree growth predictions still present a challenge to forestry scientists. Species richness, ecological behavior variations, and different climate and soil interactions make it difficult to predict and understand tree growth in managed forests.
+=====Beyond reduced-impact logging: Silvicultural treatments to increase growth rates of tropical trees=====
+[https://www.sciencedirect.com/science/article/abs/pii/S037811270700881X by M. Peña-Claros 20/9/08 ScienceDirect]
+ Use of reduced-impact logging (RIL) techniques has repeatedly been shown to reduce damage caused by logging. Unfortunately, these techniques do not necessarily ameliorate the low growth rates of many commercial species or otherwise assure recovery of the initial volume harvested during the next cutting cycle. In this study, we analyze the effect of logging and application of additional silvicultural treatments (liana cutting and girdling of competing trees) on the growth rates on trees in general and on of future crop trees (FCTs) of 24 commercial timber species.
+=====Surviving trees and deadwood moderate changes in soil fungal communities and associated functioning after natural forest disturbance and salvage logging=====
+[https://www.sciencedirect.com/science/article/pii/S0038071722000153 by Mathias Mayer  3/22 ScienceDirect]
+ Temperate forests are increasingly subject to natural disturbance by stand replacing windthrows or bark-beetle attacks. Forests are commonly salvage logged after disturbance, whereby substantial parts of biological legacies, such as surviving trees and deadwood, are removed. Despite increasing concerns about the ecological consequences of salvage logging operations, our knowledge on the effects on the soil microbiome and associated functioning remains limited.
+=====When big trees fall: Damage and carbon export by reduced impact logging in southern Amazonia=====
+[https://www.sciencedirect.com/science/article/abs/pii/S0378112705005232 by Ted R. Feldpausch 15/5/21 ScienceDirect]
+ We examined carbon export in whole logs and carbon accumulation as coarse woody debris (CWD) produced from forest damage during all phases of the first and second year of a certified reduced impact logging (RIL) timber harvest in southern Amazonia.
+=====Three decades of post-logging tree community recovery in naturally regenerating and actively restored dipterocarp forest in Borneo=====
+[https://www.sciencedirect.com/science/article/pii/S0378112721001250 by Robin M. Hayward 15/5/21 ScienceDirect]
+ Selective logging has affected large areas of tropical forests and there is increasing interest in how to manage selectively logged forests to enhance recovery. However, the impacts of logging and active restoration, by liberation cutting and enrichment planting,

+[https://www.sciencedirect.com/science/article/abs/pii/S0378112715003837 by Philip A. Martin  15/11/15 ScienceDirect]
+ Over 400 million hectares of tropical forest are currently designated as logging concessions. This practice is an important source of timber, but there are concerns about its long-term sustainability and impacts on biodiversity and carbon storage.
+=====Fates of trees damaged by logging in Amazonian Bolivia=====
+[https://www.sciencedirect.com/science/article/abs/pii/S037811271500434X by Alexander Shenkin  1/12/15 ScienceDirect]
+ Estimation of carbon losses from trees felled and incidentally-killed during selective logging of tropical forests is relatively straightforward and well-documented, but less is known about the fates of collaterally-damaged trees that initially survive. Tree response to logging damage is an important and overlooked ecological process potentially affecting 2–5% of all extant tropical trees.
+=====Brazil targets illegal logging in major Amazon raids=====
+[https://www.reuters.com/world/americas/brazil-targets-illegal-logging-major-amazon-raids-2025-02-17/ by Reuters 17/2/25]
+ PORTO VELHO, Brazil, Feb 17 - Brazilian environmental agents seized the equivalent of more than 5,000 truckloads of timber in an operation targeting one of the most heavily logged regions of the Amazon rainforest in recent weeks, officials told Reuters.

+ WILLIAMSBURG, Kentucky—Brandon Bowlin learned of the U.S. government’s plan for clear-cutting in the southernmost mountains of Daniel Boone National Forest only a few weeks after the hard summer rains of 2022, when the earth slid off a mountain beneath a slope he had once logged.
+=====Interview with a Tree-Sitter=====
+[https://www.counterpunch.org/2020/06/19/interview-with-a-tree-sitter/ by Kollibri terre Sonnenblume 19/6/20 COUNTERPUNCH]
+ On June 9th and 12th, I interviewed Lupine, a tree-sitter who is currently participating in a Redwood Forest Defense campaign to stop logging at a site in Humboldt County, California. We spoke on the phone, and though we were disconnected several times by a weak signal, we were able to have a great conversation. Tree-sitters have always been heroes to me, and I really appreciated the chance to connect with someone from the newest generation to be out there fighting the good fight.
