Forest & trees
- Global environmental changes leading to shorter, younger trees - Ongoing environmental changes are transforming forests worldwide, resulting in shorter and younger trees. Researchers found that a range of factors, including rising temperatures and carbon dioxide levels, have caused a dramatic decrease in the age and stature of forests.
- Scientists find genes to save ash trees from deadly beetle - Scientists have identified candidate resistance genes that could protect ash trees from the emerald ash borer (EAB), a deadly pest that is expected to kill billions of trees worldwide.
- Prediction tool shows how forest thinning may increase Sierra Nevada snowpack - Thinning the Sierra Nevada forest by removing trees by hand or using heavy machinery is one of the few tools available to manage forests. However, finding the best way to thin forests by removing select trees to maximize the forest's benefits for water quantity, water quality, wildfire risk and wildlife habitat remains a challenge for resource managers.
