Model predicts shifts in carbon absorption by forest canopies
An Agricultural Research Service (ARS) scientist participated in a project to fine-tune computer models that can indicate when forest 'carbon sinks' become net carbon generators instead. The results will help pinpoint the effectiveness of trees in offsetting carbon releases that contribute to higher atmospheric temperatures and global climate change. ARS plant physiologist Erik Hamerlynck ...

No Climate Benefit Gained by Planting Temperate Forests
SAN FRANCISCO, California, (ENS) - Planting forests in temperate regions such as the United States and Europe may not yield any benefit for the global climate, and may instead contribute to warming, according to a new study set for presentation Saturday at the American Geophysical Society annual meeting in San Francisco. By contrast, trees planted in tropical rainforests could indeed help to ...

Unlocking the water held by US forests not so easy, say experts
Can forests, which process nearly two-thirds of the nation’s water supply, be managed to help slake our growing demand for water and avert the worst consequences of climate change? A new report from the National Research Council suggests a need for caution in trying to tap greater water output from forests, and recommends more research and citizen involvement to help protect water quality and ...

Lightning Fires May Help Preserve Oak Forests
CLEVELAND, Ohio, (ENS) - Oak forests may be approaching extinction but lightning fires canplay a role in their regeneration, according to Case Western Reserve University biologists. Paul Drewa, assistant professor in Case's biology department, and graduate student Sheryl Petersen, suspect that these kinds of fires may provide a natural mechanism to deter encroachment of shade tolerant ...

Choice of tree species and site can increase plant diversity in plantation forest
Careful choice of tree species and sites could transform plantations into refuges for woodland plant diversity, new research from Ireland suggests. Plantations of native species on or near historic woodland and those with adequate light levels below the tree canopy were found to support more plant species. Europe’s forests cover 45% of the land area, and provide important habitat for many ...

FAO sets standards to improve national forest monitoring systems
FAO has launched free software tools that it hopes will improve the way many developing nations monitor the state of their forests to tackle deforestation and climate change. The tools are designed to assist countries through the entire lifecycle of a forest inventory - from assessment, design and field data collection to analysis and reporting. The governments of Finland and Germany have ...

Carbon canopy initiative aims to sustain Appalachian forests for climate and certified timber
While much has been written from a theoretical perspective about markets for ecosystem services, few on-the-ground projects currently exist. Yet the projects that do exist provide one of the best windows onto what actually works in practice. That’s why WRI has issued a new brief, Insights from the Field: Forests for Climate and Timber to discuss an innovative initiative called the Carbon ...
