Harvard Forest staff renovated a pole barn to house the boiler room and modern wood shop. The new boiler room (left side of the building) contains three wood gasification boilers, a 2,500-gallon thermal storage tank, a propane-fired backup boiler and associated pumps and system controls. The sloped roof on the left of the building provides a dry storage area for racks of firewood prior to loading in the boilers. (U.S. Forest Service/Rob Clark)
I recently had the opportunity to speak at the dedication ceremony for the Harvard Forest Wood Energy Project, an exciting venture partially supported by the U.S. Forest Service Northeastern Area. This woody-biomass heating system will support 50,000 square feet of the central campus buildings and five dormitories, replacing fuel-oil with renewable firewood that comes from Harvard Forest, a 3,500-acre laboratory and classroom in Petersham, Mass., and owned by Harvard University.
A unique aspect of this project is that it is at the heart of a long-term forest carbon research project. Not only are carbon flows in the Harvard Forest where the wood for the new energy system will come from already being closely studied, but now every aspect of the new installation will be very closely monitored and studied as well.

Mount Edgecumbe volcano is on Kruzof Island in Southeast Alaska, just west of Sitka. The Mount Edgecumbe Volcanic Field consists of more than a dozen volcanic vents and domes. The field first erupted more than 600,000 years ago, and volcanic activity continued until 5,000 to 6,000 years ago. (U.S. Forest Service/Jim Baichtal)
Seldom does one find a way to directly date a prehistoric volcanic eruption, but 11-year-old Blake LaPerriere opened such a door for excited scientists in Southeast Alaska.
Last September, Blake, his parents, and his younger brothers were exploring a beach on southwestern Kruzof Island, part of the Tongass National Forest landscape and just west of Sitka, Alaska, where they live. Blake investigated a deeply incised creek behind a pile of beach drift where he found a standing burnt tree embedded in a tall bank of pumice. He brought it to his family’s attention, asking “Do you think that’s from a volcanic eruption a long time ago?”
Curious, Blake’s father Zach took photos and sent them my way. Read more »
A favorite U.S. Forest Service book for kids is “Why Would Anyone Cut a Tree Down?” which explains to children that, yes, there are reasons to cut trees. (U.S. Forest Service)
The U.S. Government Bookstore, the place where you can buy the 2014 Counterterrorism Calendar for $20 or a loose-leaf copy of the Export Administration Regulation 2013 edition for $199, released its list of best-selling publications for 2013 that includes several items published by the U.S. Department of Agriculture.
“Why Would Anyone Cut A Tree Down?” is written by Roberta Burzynski, who works in the U.S. Forest Service’s Northeastern Area State and Private Forestry unit. The book shows children the life cycle of trees and how trees are a renewable resource. The 41-page book with 28 full-color illustrations can be used by parents and teachers along with online activities and lessons. Colorfully illustrated by Juliette Watts, the $10 book is ideal for parents, teachers and children. Burzynski also wrote the popular “Woodsy Owl’s ABCs” that is meant to be read by an adult to children. Read more »

Agroforestry. When you think of a forest, you don’t think of it in terms of a crop, but in many cases that’s what it is. The house you live in, the nuts and fruit you eat all comes from trees. Trees, with their root systems protect soils and soften the effects of wind. They help hold water.
The Forest Products industry contributes 4.5 percent of U.S. manufacturing’s Gross Domestic Product (GDP), produces $200 billion in products a year, provides jobs for nearly 900,000 people and is one of the top ten manufacturers in 47 states. No forests, no nuts, no windbreaks, no topsoil. Read more »
A Dust Bowl era poster urged farmers to plant windbreaks.
This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.
The language on the 1930s poster for the Prairie States Forestry Project was downright plaintive: “Trees Prevent Soil Erosion/Save Moisture/Protect Crops/Contribute to Human Comfort and Happiness.”
The mission of the project, initiated by President Franklin Roosevelt, was to encourage landowners to plant tree windbreaks on cropland ravaged by dust storms and drought. As a result, more than 210 million trees from North Dakota to Texas were planted in 18,500 miles of windbreaks, some of which still remain. Read more »
If you are sending citrus gifts, learn how to do it responsibly by visiting www.saveourcitrus.org
Out with the snake, in with horse! January 31 marks the start of the Chinese New Year. Many people will be enjoying the rich cultural traditions of this holiday such as food, parades and exchanging gifts. One traditional Chinese New Year gift is citrus fruit, such as mandarin oranges and tangerines. This fruit is said to bring luck, wealth and prosperity.
However, without proper precautions citrus can also bring something else that may not be so favorable—the Asian citrus psyllid. This pest carries citrus greening disease, also known as Huanglongbing (HLB), a disease threatening the commercial citrus industry and homegrown citrus trees alike. Although it is not harmful to humans or animals, the disease is fatal for citrus trees and has no known cure. Read more »
