St. Patrick's Day has us all thinking green. Our National Forests may not always look green but they're certainly doing 'green' things all year round. In honor of the holiday, we selected some of our National Forests where you're most likely to see green.

While not green for all of the seasons, the Pisgah is painted green come spring once the heavily forested slopes of hardwood come to life.

Green Mountain National Forest, Vermont

We’d be remiss if we didn’t include a National Forest with green in its very name! The forest lies within the Green Mountains of Vermont with elevations over 4,000 feet.
