The Presidio Trust seeks Tree Worker II/Arborist

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 a habitat for birds and other wildlife and respite from the city for human visitors.
