American Chestnut restoration

The American Chestnut foundation, in concert with other researchers, has said that although the return of this beautiful tree to our nation’s forests is on the path to success, full restoration will take longer than many people expect.  For a full history of the American Chestnut, https://www.acf.org/the-american-chestnut/history-american-chestnut/

 

Arlington completes town tree Inventory after receiving $15K grant

Thanks to the combined efforts of the Arlington Tree Committee and the Town’s Forestry Division, Arlington received a $15,000 Urban & Community Forestry Challenge Grant from the Massachusetts Department of Conservation  and Recreation for the creation of a Town-wide public street tree inventory covering roughly 100 miles of Town roads.  The inventory was successfully completed the Summer of 2017.

The tree inventory collected data on the diameter, species, health (including pest infestations), and precise location of existing trees and potential tree planting sites. The inventory was performed by volunteers and paid interns and is available to the public. The data will be used to develop a forestry management plan for the Town’s public street trees.

“Having a complete inventory of public trees will be instrumental in a successful forestry management program and helps the Town maintain its Tree City USA status,” said DPW Director Michael Rademacher. “The plan will also assist the Town to spend the generous donation left by John F. MacEachern.”

A full inventory was undertaken the summer of 2017.  Thank you to all the volunteers who helped map Arlington’s trees!

For additional information about the inventory, see the Tree Inventory section of this site.

Use your ears to ID trees!

Biologist David George Haskell teaches students how to identify trees by the sounds produced by air moving through their leaves or raindrops spattering on them. “Depending on the shapes and sizes of their leaves, the different plants react to falling drops by producing ‘a splatter of metallic sparks’ or ‘a low, clean, woody thump’ or a ‘speed typist’s clatter.’ Every species has its own song. Train your ears (and abandon the distracting echoes of a plastic rain jacket) and you can carry out a botanical census through sound alone.” Full story is available in The Atlantic.

Arlington’s New Community Tree Canopy Program

The Arlington Tree Committee has embarked on a subsidized tree planting program made possible with funds from the 2012 John F. MacEachern Bequest. The target area for this spring’s pilot program is East Arlington (Hardy and Thompson school districts) because of its sparse tree canopy. This program is managed by the Tree Committee and is not related to ongoing street tree plantings managed by Arlington’s DPW.
Available tree: White Flowering Dogwood (Cornus florida), 4-5 ft.
Cost: $50 (retail value with delivery of $150)
Delivery Date: April 29, 2017 (tentative)
See the Spring 2017 tab on this website for more information on the program or to order your tree.

Fossilized forest reveals sunspot activity 290 million years ago

Scientists can determine past changes in the sun’s magnetic field by analyzing tree rings. Now German scientists have shown that tree rings in petrified trunks from fossilized forests can be used to reveal dat about the sun’s cycles from eons ago. Data obtained from the petrified forest of Chemnitz, which was  buried by a volcanic erruption 290 million years ago, showed tree ring growth patterns similar to those caused by modern sunspot activity. Below is an artist’s impression of what the Chemnitz forest looked like.

Urban trees store more carbon

A new study shows that trees in the Boston region grow faster and store more carbon as biomass the closer they are to developed areas, even when the trees are growing in patchy areas of woods. A study just published in Proceedings of the National Academy of Science shows that forest fragments in New England may sequester much more carbon dioxide than previously predicted.

A wooden skyscraper in downtown Vancouver

A boxy 18-story wooden building going up in Vancouver, Canada, will be the world’s tallest wooden building. It turns out that engineered wood is strong and supple enough to sustain at least a small skyscraper, and apparently the large engineered beams resist fire well. For complete details and photographs, see here.
