Selecting Trees to Grow in Cities: Database Captures Urban Tree Sizes, Growth Rates Across US

Knowing the maximum size of a tree can help a planner or manager avoid future conflicts between roots and sidewalks or branches and power lines.

In the cramped environs of U.S. cities every inch counts, especially if attempting to make space for nature. But now city planners and urban foresters have a resource to more precisely select tree species whose growth will be a landscaping dream instead of a maintenance nightmare.

The U.S. Forest Service’s Pacific Southwest Research Station recently published a technical manual and launched the most extensive database available cataloging urban trees with their projected growth tailored to specific geographic regions. Read more »

Between Two Worlds: Frank Lake heals the land using modern science and traditional ecological knowledge

Frank Lake grew up learning traditional practices from the Karuk and Yurok Tribes. He developed an interest in science which led to his career choice as a research ecologist with the U.S. Forest Service’s Pacific Southwest Research Station. As a young man, he didn’t realize how unusual the experience was of spending time in two parallel worlds.

The Megram Fire of 1999 was a turning point for Lake, and the Forest Service as well. It was one of California’s largest wildland fires ever and the agency grappled with how to restore salmon in the burned over watershed. Lake knew that local tribal elders considered “fire as medicine,” and an important part of the ecosystem. The link between fire and fish is through water, they told him, and “water is sacred to all life.” Fires could reduce the number of trees in overly dense forests and improve spring flow needed by rivers to support healthy fisheries.

Ecologists Look to Traditional Knowledge to Bolster Sustainability Science

People 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. Read more »

Wildlife Underpass to Benefit Animals, Drivers

Every year in the U.S. roughly 200 people are killed in as many as 2 million wildlife-vehicle collisions and at a cost of more than $8 billion, according to the Western Transportation Institute.

But the U.S. Forest Service’s Pacific Southwest Research Station scientists, along with their collaborators in the Highway 89 Stewardship Team, are paving the way to reduce those statistics with their latest project. The team broke ground last May on its second and third wildlife underpasses along a 25-mile stretch of Highway 89 between Truckee and Sierraville, California. Read more »

Native American Students Mentored by Forest Service Scientists

The U.S. Forest Service is working with The Wildlife Society to give Native American students a chance to work as research assistants for Forest Service scientists. Forest Service Research and Development funding provides stipends for living expenses for college juniors, seniors and graduate students during their mentorship, while the society provides administrative support and coordination.

The Research Assistantship Program selects Native American students who are interested in becoming wildlife biologists. They gain beneficial hands-on experience while working with a wildlife professional on an approved project. Five students have been selected for research assistantships in this second year of the program, which will last for approximately 12-14 weeks, beginning in late spring and running through late summer.

In Recently Burned Forests, a Woodpecker’s Work is Never Done

Following a wildfire, some might see dead trees. Woodpeckers see possibilities.

The black-backed woodpecker is one such bird—a burned forest specialist—who readily chooses fire-killed trees (snags) in which to drill cavities for nesting and roosting.

When the woodpecker moves on, its cavity turns into valuable habitat for other forest-dwelling species. Read more »
