For the foothill yellow-legged frog, breeding can be a challenging matter.
It is the only true frog in western North America that breeds exclusively in streams, preferring warm stream edges. Its eggs can be swept away with spring rains and rapid currents, so a relatively long breeding season allows mates to wait until weather and water conditions offer the best chance for eggs to develop and hatch in this dynamic environment.
But yellow-legged frogs face a new challenge in a Northern California river managed for agriculture, energy, and habitat for steelhead, Chinook salmon and coho salmon. Read more »

Forest managers in the western United States often face difficult choices when it comes to reducing wildfire hazards while also maintaining wildlife habitat in forests that have changed dramatically in the last century.
The U.S. Forest Service Pacific Southwest Research Station and partners are working to find the balance between forest restoration and habitat conservation in a new era of forest management. Read more »
Invertebrates are an important food source for native waterbirds, including endangered ae‘o (Hawaiian Stilt, Himantopus mexicanus knudseni) chicks. (U.S. Forest Service/Rich MacKenzie)
Coastal wetlands the world over are known for harboring an impressive array of plants and animals. In the Pacific Islands, wetlands not only provide habitat for many unique species, including some threatened and endangered waterbirds, but also support communities of people who rely on these special places for food and other essentials.
Human development, agriculture, and rising seas are encroaching upon these wetland ecosystems and causing visible and profound changes. Another threat, less obvious to the casual observer, lurks beneath the water’s surface: non-native fish. Researchers with the U.S. Forest Service Pacific Southwest Research Station’s Institute of Pacific Islands Forestry are studying the threats posed by exotic fish species and working with partners to battle the gilled invaders.

Collisions between vehicles and wildlife are a big problem on U.S. roads. Each year, on average, 1-2 million collisions with large animals, especially mule deer and white-tailed deer, end in 200 fatalities, 26,000 injuries, and costs exceeding $1 billion. About a third of the collisions reported on rural roads are wildlife-related, and two-lane highways with speed limits exceeding 55 miles per hour are particularly problematic.
U.S. Forest Service Pacific Southwest Research Station wildlife biologist Sandra Jacobson, a transportation ecology expert, wants to make roads safer for wildlife and people. She and partners at the agency’s Missoula Technology and Development Center have produced a video, “Avoiding Wildlife-Vehicle Collisions,” to do just that. Read more »
Shyh-Chin Chen is a research meteorologist for the Pacific Southwest Research Station in California. Having experienced wildland fire literally on his home’s doorstep at least several times during the last decade, he has a passion for developing new weather forecasting tools to help firefighters predict and combat fires more effectively. Here he is shown with the Firebuster web tool. (U.S. Forest Service)
Imagine a research meteorologist focused on developing the kind of detailed weather forecasts that firefighters need to fight wildland fires. Accurate, timely information is critical.
Then understand that he has faced wildland fire on his doorstep in Ramona, Calif., near San Diego at least three times since 2003.
Those experiences fuel the passion that Shyh-Chin Chen brings to his work to protect human life and property. Read more »

It’s National Preservation Month, and people all over the country are participating in events to enrich and preserve the treasures within their communities that make them special.
Staff from the U.S. Forest Service’s Pacific Southwest Research Station recently helped to restore an ancient Hawaiian fishpond in Kīholo, Hawaii, that has a rich history and tradition of providing a sustainable food source for the surrounding communities on the Big Island. Working in collaboration with The Nature Conservancy and Hui Aloha Kīholo, Station staff from the Institute of Pacific Islands Forestry cleared and hauled debris from the fishpond perimeter in order to reduce the accumulation of sediments caused by overhanging non-native plants, which improved foraging habitat for native fish and turtles. The group also replanted culturally and ecologically appropriate native species, restored habitat for rare invertebrate species, removed invasive weeds, and participated in native plant care within an area surrounding a nearby anchialine pool, which will be used as a nursery for future restoration activities.
