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...

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...

The old proverb: “You can’t see the forest for the trees” should have continued with a line saying that it’s even harder to see below the trees. Because seeing under trees, their root system to be exact, is how scientists understand and appreciate the things that will determine what we all see in...

Focusing on international markets, renewable energy and a community’s inherent assets, rural businesses find dynamic paths to prosperity. To see this in action, I headed to Boonville, New York. Mark Bourgeois was born and raised in Boonville and today is President of CJ Logging Equipment and 3B...

Pablo Chacón, a young Guatemalan farmer who is studying agroforestry at the Tropical Agricultural Research and Higher Education Center (CATIE) in Turrialba, Costa Rica, can now show the people in his home community how livestock grazing and hardwood forests can co-exist and prosper. Earlier this...

Trees do plenty of work to sequester carbon on their own, but many forests are not as healthy as they should be due to fire suppression and climate change. This can leave trees vulnerable to large scale insect damage, fire or drought, and much of the carbon stored by forests is lost to the...

Drought, especially prolonged or severe drought, can be a major stress in forest ecosystems. Drought can kill trees directly or indirectly through insect attack or wildfire. Both of which are more likely to occur during drought. Tree mortality impacts most of the ecosystem services provided by...

A small group of conservation enthusiasts gathered at Ralph Duyck’s farm near Forest Grove, Oregon with a shared goal. They wanted to protect water quality and fish and wildlife habitat in and around the Tualatin River, an 83-mile tributary of the Willamette River that runs through Portland. The...

“A mature Giant Sequoia can use 500-800 gallons of water every day during the summer,” said Anthony Ambrose, a tree biologist at U.C. Berkeley. “That’s a lot of water necessary for just one tree.” For the first time in at least 125 years, Giant Sequoias in the southern Sierra Nevada Mountains of...
