The USGS uses a variety of survey tools—including personal watercraft (jet skis) equipped with GPS and sonar—to measure how sandy coastlines change over time. Sandy coastlines are a valuable resource that protect human-made structures from waves, serve as habitat for important species, and provide a variety of recreational opportunities.

The smell of a fresh cut Christmas tree can evoke visions of majestic evergreen forests teeming with winter wildlife. In truth, more than half of U.S. Christmas trees come from farms in Oregon, North Carolina, or Michigan. Cut Christmas Trees area commodity, tracked by the U.S. Department of Agriculture just like corn or soybeans.

In this episode we sit down with USGS wildlife biologist Joan Hagar and discuss her recent study on songbirds in the Pacific Northwest. New research indicates a possible relationship between reductions in the abundance of some species of songbird and reductions in the amount of deciduous trees in evergreen forests.
