“A mature Giant Sequoia can use 500-800 gallons of water every day during the summer,” said Anthony Ambrose, a tree biologist at U.C. Berkeley. “That’s a lot of water necessary for just one tree.”
For the first time in at least 125 years, Giant Sequoias in the southern Sierra Nevada Mountains of California are showing significant amounts of “dieback” in their foliage due to several years of drought. Read more »
U.S. Drought Monitor Drought Assessment map
Drought patterns have always fluctuated and are expected to become increasingly dynamic in the years to come, making managing working lands profitably more of a challenge. Because specific actions for building resilience to drought vary with location and forest type, USDA is helping land managers connect with experts and find region-specific information and tools through the USDA Climate Hubs.
Recent historical drought events vary from region to region, with the western U.S. showing a trend toward dry conditions while trends in the East are more complex. So how can land managers mitigate the impacts of drought on their lands? Read more »
Forest Service scientists use a greenhouse in Washington State to grow bluebunch wheatgrass as part of their current reciprocal transplant project. It is one of the largest and most intensive projects of its kind ever attempted.
Wildfires in sagebrush and other range ecosystems are increasing in frequency and severity, often in relation to drought conditions and intrusive species like cheatgrass, a non-native, highly flammable invasive species that establishes itself as a monoculture and crowds out native grasses and forbs.
“What’s preferable to a monoculture is a diverse plant community that includes native grasses, forbs and shrubs,” said Francis Kilkenny, leader for the Great Basin Native Plant Project, a joint effort of the U.S. Forest Service and the Department of Interior’s Bureau of Land Management, or BLM.

Tom Fry is the Western Conservation Director of the American Forest Foundation (AFF). AFF and the U.S. Forest Service hold a long-standing partnership in pursuit of protecting and conserving the important forest benefits that come from family and individually owned forest lands across the United States and ensuring the next generation of Americans understands and value forests for all the benefits they provide.
As we get ready for the 2016 wildfire season, a recent report from the American Forest Foundation (AFF) looks at one of the most important, but often overlooked, issues related to forest health: the relationship between water supply and the risk of fire to our forests. Read more »
Land and Water Conservation Fund, Land Acquisition Budget Proposal FY2017 map. (Click for a larger version)
Over 50 years ago, a visionary Congress established an innovative program to bring communities together to invest in open spaces and recreational opportunities that are an essential part of our nation’s heritage and economy. Since then, the highly successful Land and Water Conservation Fund has helped to protect working forests and ranches, preserve our public lands — parks, refuges, forests, rivers, lakes and wildlife habitats — and provide access to outdoor recreation across the nation for use and enjoyment by all Americans.
President Obama is committed to passing on America’s public lands and waters to future generations in better shape than we found them. That’s why he is proposing full funding for the Land and Water Conservation Fund in the Fiscal Year 2017 budget, and pursuing permanent authorization in annual mandatory funding for the Fund’s programs beginning in 2018.

USDA Results: Caring for our Land, Air and Water. Preserving Precious Natural Resources for Tomorrow.
At the beginning of this year, we launched a year-long reflection on USDA-wide results achieved over the course of this Administration. This week begins a month-long focus on seven years of USDA accomplishments to preserve our natural resources for tomorrow’s generations – accomplishments that have only been made possible with the hard work of our staff at USDA and the support of our steadfast partners.
I’m proud of the work that we’ve done to build lasting partnerships to care for our nation’s unparalleled public lands and support producers as they conserve our nation’s land, water and soil. Please take some time to read a full story of our results on my Medium page at: www.medium.com/usda-results. Read more »
