Researchers at North Carolina State University have successfully reduced lignin content in aspen trees by 45-50% through genetic modification. This reduction increases cellulose content and accelerates tree growth, offering economic and environmental advantages for the wood, paper, and pulp industries.
A newly discovered fungus, estimated to be between 2000 and 8500 years old, has rewritten the concept of individual organisms. The fungus, a clone of Armillaria ostoyae, covers an area of 9.65 square kilometers and has implications for forest management practices.
A new GIS tool called GeoWEPP can rapidly assess soil erosion and sediment delivery in streams after wildfires, allowing forest managers to quickly plan and implement conservation measures. The tool guides users to select the best and most cost-effective conservation measures to mitigate erosion and protect water sources.
A team of US researchers study Polish forest plots with 14 different temperate tree species to understand biodiversity and ecosystem structure. They investigate how tree species influence the environment, soil acidity, and decomposition.
A new study reveals three distinct species of African elephants: savanna, forest, and west African. The west African population has been diverging for over two million years and is threatened with extinction due to human activities.
Red pine groves in the Boundary Water Canoe Area may vanish due to lack of natural fires. A new model suggests that continued fire suppression would lead to the loss of red pines and other tree species within 300 years.
Researchers found HMO patients with capitation payment received 17% more health counseling and preventive services, but spent an average of 2 minutes less time with doctors. This study dispels fears about capitation payment's impact on quality care.
Research finds that larger forest stands can help control caterpillar infestations by reducing the effectiveness of parasites and diseases. The study suggests that forests larger than 100 hectares are more effective in suppressing outbreaks, which could lead to increased fibre production if defoliation is reduced by just one year.
Researchers question the efficacy of prescribed burning in reducing large, intense forest fires. They argue that this technique is not suitable for closed-canopy forests and shrublands where natural fires are more frequent and severe. This approach can also have negative ecological consequences.
A decade-long study suggests forest management can influence carbon uptake, but factors such as tree species and age confound the process. The researchers' findings validate a new method for measuring carbon dioxide levels, highlighting the need for careful consideration of forest management strategies.
A new book documents dramatic recent changes in southeast's ancient soils formed over about 70 million years and how human use transformed them over the last two centuries. Soils were altered when primeval woodlands were turned into cotton fields, eventually regrowing as pine forests.
The Terra satellite beams daily images of western U.S. wildfires to NASA, which are then transmitted to the Forest Service. The collaboration uses MODIS data to create Active Fire Maps that help resource allocation decisions and aid in public understanding of fire locations.
The project, initiated in 1997, incorporates multiple viewpoints from the scientific, corporate, and environmental communities to balance ecology and economics in forestry management. The team's approach has formed notable partnerships and is regarded as a model for others striving to achieve this balance.
The traditional 'ponderosa pine model' of forest fire management is being questioned due to its limitations. Presenters will present data on the ineffectiveness of prescribed burns in California's shrubland areas and boreal forests, highlighting the dominant role of weather and human demographics in fire regimes.
Riparian forest management prioritizes both water and forest health to protect essential links between land and water. The book provides site-specific guidelines for addressing fragmented ecosystems and diverse interest groups, ensuring the health of eastern riparian landscapes.
Aging South Dakota windbreaks are in need of renovation, posing increased risk to agriculture from wind damage. Well-developed forested riparian areas reduce nitrogen in groundwater by up to 100% and surface runoff by up to 98%.
A group of Oregon State University scientists emphasize the potential benefits of genetic engineering in forestry, including faster-growing trees that can reduce the burden on native forests. They argue against 'genetic extremism' and call for a more careful analysis of the issues based on science.
A new study by Penn State researchers improves the regional climate assessment of the Mid-Atlantic Region. The research involved gathering input from over 95 stakeholders representing industry, environmental groups, government, and research organizations. Key findings highlight the importance of human health in addressing global change...
The study found that public perceptions of the forest prioritize residential quality of life, community, and environmental ethics. This differs from land managers' focus on tangible aspects like water, wood, and wildlife.
Precious Woods Ltd, a forestry company in Brazil, has been awarded the ESA Corporate Award for its innovative approach to sustainable forest management. The company's use of advanced planning and ecological principles has resulted in the conservation of 97% of primary forest in the State of Amazonas.
Research suggests shrews can serve as an indicator of environmental health due to their high sensitivity to environmental change. In the Central African Republic, 16 species of shrews were found thriving in micro-territories, defying expectations for such limited habitats.
