Trees provide the very necessities of life itself. They clean our air, protect our drinking water, create healthy communities, and feed the human soul. But these life necessities are threatened around the globe.
Our own Olmsted Woods is the last vestige of an extensive Oak and Beech forest on Mount St. Alban – now the site of Washington National Cathedral and the three Cathedral Schools. All Hallows Guild restored the five-acre Olmsted Woods over a 10-year period, completed in 2008 at a cost of nearly three million dollars. Our Olmsted Woods volunteers meet regularly on Wednesday mornings to maintain the health of the woods and remove invasive plants. You are welcome to join them by filling our our Volunteer Form.
