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 »
Root disease tree failure resulted in the loss of this car.
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 our future forests. A new publication just released by the US Forest Service seeks to help forest managers recognize important root diseases and provide the best management strategies.
Ordinarily, we depend on decay organisms to break down wood to recycle enormous amounts of above ground materials such as leaves, limbs, and tree trunks. Without these subterranean decomposers, we would find ourselves buried in forest debris. But what makes beneficial decay organisms go bad and attack the root systems of living trees? In a word, disease. Read more »
Administrator Sam Rikkers tours the lumber yard with CJ Logging Equipment and 3B Timber President, Mark Bourgeois.
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 Timber. A stable employer in the region, 3B Timer processes softwood trees on-site into utility poles. 3B Timber utilized Rural Development’s Business & Industry (B&I) loan guarantee to expand their operations. As Mark explained, his company now exports 80% of its poles to Canada, expanding international trade and supporting job creation in the region and state. Read more »
Pablo Chacón, a Guatemalan farmer, takes notes at the CATIE dairy farm and research center in Turrialba, Costa Rica, where he is studying agroforestry on an FAS-funded scholarship.
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 month, he told me and other Foreign Agricultural Service (FAS) visitors to CATIE that the education he gained from his FAS-funded scholarship to CATIE has equipped him to be a change maker.
“CATIE’s research in the tropics shows that degraded lands can be restored using combined forest and pastoral production systems,” Chacón said. “The benefits of trees in pastures are clear: The shade helps reduce stress in animals during the dry season, keeps moisture in the soil and retains the strength of pastures during the dry season.” Read more »
Forests and wood products are powerful tools to help mitigate the impacts of climate change. (Click to view a larger version)
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 atmosphere as trees die.
The U.S. Forest Service is committed to the storage of carbon using wood products through the green building and wood products strategy. This strategy involves putting people to work in rural communities, enhancing resiliency of our ecosystems, and sequestering carbon by promoting the use of wood products in large building construction.

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 forests, including the amount of wood that grows, how much carbon is captured and stored, the health of critical wildlife habitat, water yield and quality, and even whether it’s safe to pursue recreational activities such as hiking or hunting.
