Tree Worker II / Arborist
The Presidio Trust is seeking a Tree Worker / Arborist. The Presidio of San Francisco was once an Army base; it’s now a new kind of national park. The Presidio’s richly forested and designed setting is one of the Army’s most impressive accomplishments in landscape architecture. No other military installation in the nation has ever undertaken landscape planning on such a grand scale. A soldier standing on the Presidio’s windy ridgeline during the Civil War years would have written home about sandy dunes and the open prospect to the bay. Beginning in the 1880s, the Army planted a vast eucalyptus, pine, and cypress forest. Thousands of trees were planted along the Presidio’s ridges and entrance gates. Today, the 300-acres forest is the largest feature that contributes to the Presidio’s National Historic Landmark District. It also provides habitat for birds and other wildlife and respite from the city for human visitors.
Our ideal candidate is an experienced tree worker in all aspects of arboriculture and urban forestry which is able to fulfill the obligations of the Vegetative Management Plan.

About the Presidio Trust Tree Crew
Over the past 18 years, our Tree Crew has planted 40 acres of young trees at 44 sites. In total, more than 5000 trees have been planted. The rejuvenation is especially visible along West Pacific Boulevard near Julius Kahn Park; at the Arguello Gate, where cypress trees planted just a few years ago already rise 30 feet; along Kobbe Boulevard, where wind studies have informed how trees should be placed on the Presidio’s blustery western edge; and near the World War II Memorial, where trees resistant to pine pitch canker are thriving. Trees that have been felled continue to contribute to the park’s vitality – they are used as compost to increase soil fertility, are milled for benches and fencing, and are immortalized through art, as seen in Andy Goldsworthy’s Presidio pieces Wood Line, Spire, and Tree Fall. The Trust’s reforestation effort has also contributed to an increase in the bird population. The Trust also welcomes the public to get involved by participating in a volunteer tree care program. More than 1,000 volunteers have contributed more than 5,000 hours caring for young Presidio trees.
