Small variations in breeding pools make for big differences in Yosemite toad use

Paul Meznarich, June 30, 2017 at 12:00pm

The Yosemite toad (Anaxyrus canorus) is a rare species found exclusively in California’s Sierra Nevada. While its range encompasses hundreds of miles, spanning five national forests and two national parks, the livelihood and future survival of this federally threatened species may come down to mere centimeters.

Ecologists Look to Traditional Knowledge to Bolster Sustainability Science

Diane Banegas, September 19, 2016 at 10:30am

People all around the world manipulate ecosystems for their own purposes. It’s what you leave behind when you’re finished working or living in the area that determines whether the ecosystem survives or is irreparably harmed for future generations. For scientists like John Parrotta, national program leader for international science issues with the U.S. Forest Service, knowing what to leave behind is not always found in a college textbook or scientific journal.

Forest Service Databases Reimagined as Interactive Web-based Maps and More

Diane Banegas, September 19, 2016 at 10:15am

Forestry data is now available to resource professionals and the public in an engaging portfolio of web-based tools and applications.

The U.S. Forest Service’s Forest Inventory and Analysis (FIA) Program is in the information gathering business. The program invests $75 million a year to collect data across three themes: field inventories of forest land, a census of the forest products industry, and surveys of forest land owners.

Forest Service Research Improves Road Management and Influences National Policy

Cody Sullivan, August 11, 2016 at 11:15am

Forest Service researchers collaborated with partners to develop analytic tools that identify specific areas where water drains off forest roads and carries unwanted sediment into waterways. These tools, GRAIP (Geomorphic Road Analysis and Inventory Package) and GRAIP-Lite, informed new Environmental Protection Agency (EPA) policy decisions.

Fire and Forests

Since the Forest Service officially established its branch of research more than 100 years ago, it has studied fire and its positive and negative roles in sustaining U.S. forests and grasslands.

U.S. Forest Service and Chinese Academy of Sciences Enter into a New Research Partnership

Cody Sullivan, July 1, 2016 at 12:45pm

On May 20, 2016, the U.S. Forest Service and Chinese Academy of Sciences jointly entered a scientific partnership. After years of sharing a mutual interest in urban forestry and ecology, the duo signed an official Letter of Intent declaring their new collaborative relationship.

Every year urban populations in the U.S. and China grow, increasing the need for a greater understanding of the natural aspects of a city (urban trees, wildlife, water) and how they interact with the social parts of cities such as clean water, climate resilience, or sustainable living.


Genetic Conservation Programs Can Help Protect Tree Species from Pathogens, Insects, and Future Climate Change

Cody Sullivan, June 23, 2016 at 11:45am

In today’s world of changing climates and unnatural human transport of pathogens and pests, a species’ survival relies on its adaptability more than ever. Easy-going temperaments and flexibility aren’t the types of adaptive natures a species needs. A species needs genetic diversity so that within its populations certain traits already exist that can help it adapt to and survive new threats. The U.S. Forest Service is a leader in realizing the need to conserve genetic diversity and operates genetic conservation programs to maintain it within tree species.
