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 ...

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 ...

Careful urban tree planting and pruning needed to reduce trapping of air pollution
Careful planting and pruning is needed to ensure that air pollution in tree-lined streets is minimised, new research suggests. While planting trees in urban areas can have many benefits, such as enhancing biodiversity, trees can trap particulate matter pollution, say the study’s authors. Particulate matter (PM) air pollution is a component of vehicle exhaust emissions and PM2.5 (particles ...
