The Discovery Program Unveils the American Forest Project And Forest Musings

There is a darkness in the forest – a depth beyond the obvious. Maybe it is age. Maybe it is that a forest has been a forest for a very long time, and that being in one makes us understand that we are visitors here. Trees struggle. They do not just live, they struggle and they die - they are torn by the struggle and very few, maybe one in one hundred thousand survive the forest – live beyond it and ultimately above it. A forest is not just a forum of trees – it is a symphony of life, both plant and animal. The trees we see are the products of struggle…a twist from a storm… a lean or a reach to light… a casting off of weakness in the ever-present effort to live. Trees are rooted in their own death.
Forests change over time through a process of succession as tree species become dominant or lose out to other species. It is a natural process, but with introduced blights, pathogens and non native tree species our forests are being transformed before our eyes. Succession is sped-up and wildlife suffers as food sources disappear and other less productive species replace them. This is of course not just a local problem; as populations have grown and cultures have become more connected through travel and commerce, a huge exchange of plant species and their accompanying problems have been transported all over the earth. The American chestnut, nicknamed the redwood of the east because of its immense size and stature in the eastern forests, was the dominant tree east of the Mississippi until early in the last century. It is now blighted by an introduced Asian fungus, and survives in eastern forests only as an under-story plant resurrected from the roots of ancient trees each season. Rarely do the trees gain enough access to light to bloom and rarer still do trees produce a nut crop. The result has been devastating for humans and animals. The nutritious nuts were so prodigious that they sustained families through long winters and fed countless wildlife populations. Native Americans and colonists survived on the chestnuts and the yearly bounty brought much needed income to mountain people. Chestnut lumber was resistant to rot and is still found in many of the log cabins in the East built before the turn of the last century. As visitors approached the Blue Ridge Mountains in the spring they often thought they saw snow on the mountainsides – the vision was the white bloom masses of the chestnuts. The acrid scent of the bloom traveled on the breeze for miles. Many of the trees are still struggling to survive. Each spring the old roots send up new shoots and each year the shoots from the previous year are killed by the girdling affect of the blight. The resulting death cluster is constantly spreading outward from the old roots. Photo courtesy: The American Chestnut Cooperators Foundation |

American Chestnut Efforts

There are efforts in place to bring back the American chestnut. The American
Chestnut Foundation, TACF, is working with native trees crossed with the
blight carrying yet resistant Asian Chestnut. The crosses hold promise but
the work is slow due to the nature of trees – it takes years for them to
grow, and the hopeful outcome of an American like tree that retains
resistance to the fungus is perhaps ten years off. Another organization, the
American Chestnut Cooperators Foundation, ACCF, is working with pure
American chestnut trees and identifies ‘mother’ trees that have shown
natural resistance to the blight. These trees are bred back to other
resistant trees, and the offspring are distributed to cooperating growers
who carefully monitor the progress of their saplings and document the onset
of blight infestation and resistance. National Forests, parks, landowners,
and wildlife organizations have donated their time and money to plant
thousands of trees. The Foundation is confident that we will see a purely
American and indeed regionally adapted tree that can compete in natural
forests. The timeline for this outcome depends largely on the trees
themselves, but the Foundation suggests that within fifty years the tree
will be fully returned to a sustainable population in the mountains east of
the Mississippi.

The Discovery Program has embarked on a mission called the American Forest Project, and local tree species affected by various introduced maladies including the American elm, eastern hemlock, and the American chestnut are being cultivated and planted in the Virginia Piedmont area. So far this year 100 American chestnut and 100 American elm trees have been planted. Two hundred chestnuts were donated to the American Forest Project by ACCF in the fall of 2004 and will be potted this winter. They will be available in the fall of 2005. The Discovery Program, located at Locust Grove and Prospect Heights Middle Schools in Orange County, Virginia seeks to back up the Virginia Standards of Learning (SOL) in science while developing a community service and outreach program for its students. So far it has been a terrific success for student learning and community outreach. If you are interested in donating to the Discovery Programs’ American Forest Project, would like to purchase these rare trees, or you have suitable land and would like to become a cooperating grower please contact either Smith Coleman at LGMS or Lars Holmstrom at PHMS.
Kindest Thanks, Smith Coleman Discovery Program Director, LGMS
