Major Gift to SUNY-ESF Chestnut Restoration Project
The SUNY College of Environmental Science and Forestry (SUNY-ESF) has announced a grant of $3.2 million over three years from the Templeton World Charity Foundation in support of efforts to restore the endangered American chestnut. This is SUNY-ESF’s largest-ever charitable gift.
The funding will support research and efforts to restore the economically and culturally significant tree species, billions of which were killed by a blight in the early twentieth century. ESF has genetically engineered a new strain of chestnut that includes a single gene from wheat, enabling the tree to detoxify the oxalic acid produced by the invasive fungus that causes the blight. According to the school, this is the first time scientists have sought approval for genetic engineering to restore a native tree species. Earlier this year, the research team submitted to federal agencies a petition that lays out the case for public distribution of the genetically engineered strain.
Some blog posts resonate long past their original publication date date. Transplanting and a Deeper Look at “Fall Hazards” was one of the top five posts in 2015 and was the second most viewed post in 2016. Former NYC Director of Street Tree Planting Matt Stephens and Taking Root Editor Michelle Sutton coauthored this story questioning commonly held beliefs about “fall hazards,” mostly as it applies to B&B trees, but they also discuss the interaction of the fall season with other production methods, like bare root. Nina Bassuk helped craft the section called “The Five Branches of Transplanting Success,” which should be of interest to anyone planting trees.
Kristy King and NYC Forest Restoration: Dreaming Big for the City’s Natural Areas Many readers wanted to learn about the work of the NYC Natural Resources Group, which manages 5,000 acres of forested natural areas across the five boroughs of NYC, and about Director of Forest Restoration Kristy King. Her dream for NYC: “… that all forested areas are dominated by native species and that invasive species have been managed to the point that natural forest regeneration is occurring and that the public holistically values the natural resources in their area.”
NYSDEC Urban Forestry Intern Jennifer Kotary: Get to Know Her! Many blog readers were keen to know about this dynamic up-and-comer. “My internship research involved in-depth exploration of what communities are doing to protect and build green infrastructure across the state. Via Mary’s [Kramarchyk] assigned projects, I was able to produce tangible evidence that there is quite the statewide collective will to plant and nurture an expanding canopy as well as many career and volunteer opportunities to do so.”
SMA’s 2016 Urban Tree of the Year: Musashino Zelkova generated a lot of buzz. ‘Musashino’ has been a successful and popular street tree for many more years in Japan, proving itself useful as a narrow, upright form of zelkova. It can tolerate drought and heat and is pH adaptable and pollution tolerant. See a list of all the past SMA Urban Trees of the Year here.
Gary Raffel: Get to Know Him! Gary has served the Council in a variety of capacities, including as a board member. “I started Dynamic Tree Systems in 2002, offering general tree care service as well as Plant Health Care and Integrated Pest Management programs. I later wanted to find a niche in the industry and purchased a Tree Radar Unit at a time when there were only three of us in the U.S. and eleven people in the world using the equipment. A few years later I became the company’s international trainer, such that when a new unit was sold I would fly to the particular client and spend a week training them on their new equipment (I still do that, in addition to Dynamic Tree Systems).”

I became aware of the American chestnut (Castanea dentata) when my father pointed out the remains of dead trees to me when I was just a boy. I was aware of the resprouts that keep coming up and then dying back from the blight. Then, when I was a teenager I witnessed the death of all the great American elms on our farm, which gave me a vision of what must have happened when the Chestnut blight killed all the chestnuts 50+ years earlier. I think that the devastation to ash trees today by Emerald Ash Borer and ash yellows and decline is giving the next generation a glimpse of what has happened in the past.
