Tree Breeding: Creating Tomorrow’s Healthy Forests Today

Immobile and long-lived, trees endure extreme weather, fires, and pests for tens, hundreds, and even thousands of years. In Fishlake National Forest, Utah, there is a quaking aspen colony spanning 106 acres that is roughly 80,000 years old. To give you a sense of scale, if the average human lives 79 years, this aspen colony has already lived over a thousand times longer!

Climbing Trees – How I Met My Beetle Family and Gave Back to the Community

April may be Invasive Plant Pest and Disease Awareness Month, but I live it year-round. I spend my days with a team of fellow tree climbers, looking for signs of Asian Longhorned Beetle (ALB) damage in the treetops of Bethel, Ohio.

Reforestation Tool to Help Determine Where to Plant Tree Seedlings

After timber harvest or a forest fire, reforestation is essential for a productive working landscape and healthy ecosystem. When replanting you need to decide where you will get tree seeds or seedlings. To help you and other forest land managers, reforestation scientists at the USDA Forest Service Pacific Northwest Research Station, Oregon State University, and the Conservation Biology Institute developed a web-based mapping application, the Seedlot Selection Tool.
