Lyon Street Phase IV Reforestation

​​​​​​​This stand of eucalyptus trees borders three previous forest restoration sites along Lyon Street. Nearly one acre in size, the stand consists primarily of 50 blue gum eucalyptus trees and 25 Monterey cypress trees that are in poor health. In late September and early October 2021, the trees will be replaced with a variety of eucalyptus tree species of varying size and stature. Erosion control measures and drip irrigation will be installed.

About Reforestation in the Presidio

Our revitalization of the Presidio forest, planted by the U.S. Army beginning in the 1880s, began in 2003. Since that time, 40 acres all around the park have been replanted with 5,000 young trees.

Reforestation has contributed to an uptick in bird diversity in the Presidio, a clear indication of a sustainable ecosystem. Dying trees also often get a second life in the park, repurposed as benches, fencing, and even artworks like Andy Goldsworthy's Spire, Wood Line, and Tree Fall, which are viewed by thousands of Presidio visitors each year.

The Trust welcomes you to get involved in caring for your national parks by participating in our volunteer programs! Learn more at
