Even a little forest management significantly increases water runoff in the Central Sierra Nevada and other semi-arid regions, while drier forests need more extensive treatments, according to a new study published recently in the journal Ecohydrology. “The result is more runoff to...
Stands of brown, dead trees throughout Sierra Nevada forests
The most extreme drought event in hundreds of years caused a catastrophic die-off of the Sierra Nevada’s mature trees in 2015-2016. A study published today in Nature Geoscience details how UC Merced Professor Roger Bales and his colleague...
pine tree seedlings in a greenhouse
Climate change is bad news for forests, and a new study by UC Merced Professor Emily Moran demonstrates one aspect of that news. Higher summer temperatures hurt tree seedlings’ growth and survival. But whether that is entirely bad depends...
A verdant forest floor
A nine-year experiment by a UC Merced Department of Life and Environmental Sciences professor and his colleagues is illuminating the importance of soil carbon in maintaining healthy and functioning ecosystems because of its influence on the microbial...
A picture of a soil chronosequence in Hawaii shows yellow sulfur-rich soil that has built up over millions of years.
A rigorous, first-of-its-kind global study provides new insights into the natural history of soil biodiversity and shows that changes in soil pH during soil development is a major driver of most of that biodiversity. Published recently in the...
Waterbirds take flight over a large wetland area along the Pacific Flyway.
Climate change is having a profound effect on the millions of migrating birds that rely on annual stops along the Pacific Flyway as they head from Alaska to Patagonia each year. They are finding less food, saltier water and fewer places to breed and...
A $4.6 million grant to UCs Merced and Irvine will help researchers develop new tools and methods for better managing the state’s forests, shrub lands and grasslands. The Innovation Center for Advancing Ecosystem Climate Solutions, a three-year...
The French Meadows Forest Restoration Project, an innovative collaboration approved this week, aligns the expertise of the Sierra Nevada Research Institute at UC Merced, the U.S. Forest Service, the Nature Conservancy and other agencies and groups to...
UC Merced researchers have evidence that California’s forests are especially vulnerable to multi-year droughts because their health depends on water stored several feet below ground. “Each year our forests, grasslands and shrublands depend...
The Earth is changing, and humans face major challenges if they hope to adapt, survive and preserve any semblance of the world as it is now. Humans will need to create sustainable food, water and energy supplies; curb climate change; eliminate...
