New research reveals that sustainable forestry policies in the Congo Basin may inadvertently cause increased deforestation and timber production. The studies found that selective logging, often done under compliant policies, leads to indirect deforestation by spreading activities over larger areas. Human settlements also grow near lega...
A Florida Tech-led study refutes the theory that Amazonian rainforests were created through ancient managed landscapes. The research, published in the Journal of Biogeography, suggests that pre-European human activity had a limited impact on the ecosystem.
A recent study in Primorye, Russia, suggests that logging companies can be essential for endangered Blakiston's fish owls. In fact, lands leased to logging companies account for 43% of suitable habitat, while protected areas only cover 19%. This collaboration enables the protection of nearly half of all potential fish owl home ranges.
Researchers found that sustainably logged tropical Amazonian forests can recover their carbon stocks within a cutting cycle of 20 to 30 years. The study suggests that the time to recover initial carbon stocks depends almost exclusively on logging intensity, providing useful insights for forest managers and policy makers.

A study among the Makushi people in Guyana reveals that men are more likely to pursue long-term relationships when women are in short supply. The researchers found that when women are abundant, men tend to seek multiple short-term partners, but when they are scarce, men value and attempt to maintain a single partner.
A study published in Forest Ecology and Management found that salvage logging increases sediment in water runoff, causing erosion and damage to fish habitats. Leaving slash on the ground, breaking up equipment trails with water bars, and replanting vegetation are recommended best management practices for minimizing ecological effects.
A meta-analysis of studies on reduced-impact logging (RIL) and conventional logging found that RIL causes smaller shifts in species abundance and less harm to birds, arthropods, mammals, and bats. RIL certified timber can support the diverse benefits of tropical forests and promote sustainable forestry practices.
A new study led by Dartmouth researcher Jodi Brandt shows that China's conservation efforts have displaced ancient community-managed protections, accelerating old-growth logging. Total forest cover increased, but biodiversity value decreased as scrub and secondary forests dominated the landscape.

A study published in PLOS ONE found that more than 80% of tropical forests in Malaysian Borneo have been heavily impacted by logging. Satellite imaging revealed approximately 226,000 miles of roads constructed throughout the forests of this region.
Retaining moderate levels of logging debris helps increase growth rate of Douglas-fir seedlings by inhibiting competing herbaceous vegetation and preserving soil water. This leads to increased early growth in seedlings, with higher growth rates observed at 80% debris cover without herbicide treatments.
A study found that computerized surveillance in the home causes significant changes in behavior to control privacy intrusion. Participants adjusted their daily practices to maintain a tolerable level of surveillance, but unexpected events could disrupt these adaptations.

Researchers found that clear-cut logging significantly increases the risk of avalanches penetrating into forest cover. The study provides new methods and data to predict runout distances and assess risks to facilities below avalanche terrain. This knowledge is crucial for land-use planning and management of resources.
Researchers at the University of Texas at Austin have devised a new type of network that allows users to authenticate without relying on unique identities. The novel network structure eliminates identity theft, loss of anonymity and misplaced trust by using an addressing system with user-selected pseudonyms.
Research found that clearing trees and shrubs within 40 meters of houses afforded the greatest protection against house loss during Black Saturday fires. However, intensive fuel reduction can be expensive and have environmental impacts, and is not a guarantee of safety.
A study by University of Leeds ecologists reveals that over 80% of ant species found in pristine forests were also present in logged areas. This finding has implications for forest conservation, suggesting that areas previously thought to have little value can still support diverse communities.

A Purdue University researcher used NASA satellite data and Google Earth to detect changes in North Korea's Mount Paekdu Biosphere Reserve, finding that up to 75% of the forest had been removed through extensive logging. This has raised concerns over biodiversity loss and habitat destruction in the region.
A new study found that protected areas with strong anti-poaching efforts are critical for maintaining populations of forest elephants, western lowland gorillas, and chimpanzees in the Ndoki-Likouala Conservation Landscape. The region is considered one of the most important sites in Central Africa for all three species.
A study found that leaving logging debris behind suppresses the growth of invasive plant species like Scotch broom and blackberry, allowing native plants to thrive. This method saves costs but may increase fire risk, making it a more favorable approach for forest management.
