New Tool Allows Researchers to Predict Forest Death From Drought 



Researchers at UC Davis have created a new method to figure out how much carbon trees were putting into their reserves, and how these reserves dwindled as drought wore on.



Scientists have a new tool to predict the impact of drought on forests. Researchers in UC Davis’s Department of Plant Sciences have developed a new method to understand the likelihood that a tree will die or recover based on drought conditions a forest is exposed to. Trees use water to process carbon dioxide in the air, turning it into nutrients for the plant. Without water, trees rely on reserves of carbon to continue growing, but when those reserves run out, the tree dies. The new method connects precipitation, soil moisture, and heat to the amount of carbon trees are putting in reserves, and allows researchers to understand how trees are using that carbon reserve. This improved understanding of how forests die or recover from drought can improve forest management in the face of drought.








News & Updates




Western Water and Working Lands Framework for Conservation Action


The USDA Natural Resources Conservation Service (NRCS) has developed a new framework, the Western Water and Working Lands Framework for Conservation Action, to help producers conserve water, address climate change, and build drought resilience in the West. NRCS identifies six major water and land resource management challenges, guidelines for identifying vulnerable agricultural landscapes, and 13 strategies for NRCS leaders in western states to use now to collaborate with partners, water resource managers and producers.

New Method For Predicting Record-Setting Heatwaves


Extreme heatwaves are becoming a more common occurrence in the U.S. and around the world. Could these events, such as the 2021 Pacific Northwest heatwave, have been foreseen? New research models extreme scenarios for various cities and presents a new technique that could help communities better prepare for life-threatening heatwaves. Learn more >


Climate Change Worsening Fires in British Columbia


Wildfires in Canada have impacted air quality across the United States this summer. A new study has attributed these record-setting wildfires to climate change. Even when there is ample precipitation in British Columbia, rapid warming and increased evaporation are driving an increase in dryness, leading to an increase in burned area and a longer wildfire season.

September Drought Outlook


During September, drought persistence and expansion is expected for a huge swath of the Central US. By the end of the month, large areas of drought are anticipated to cover the Northwest, the Southern Rockies, the Southern Great Plains northward into portions of the Northern Great Plains and Midwest, the South, Hawaii, and a bit of CA/NV, the Northeast, and Mid-Atlantic. Drought improvement is favored for parts of the Southwest and Southeast along with drought areas of Puerto Rico and the western Virgin Islands. Learn more >
