Volunteering at Crissy Field is a great way to help the environment, because it is a diverse area with many different species of plants and animals. Unfortunately, Crissy Field is also very delicate, and requires a fair bit of maintenance work to be done to preserve it. By volunteering, you can help preserve this area, as well as hang out with your friends while doing valuable community service. |
A Brief History of Crissy Field Crissy Field was a home to the Ohlone Native Americans around 3000 B.C., as it had a variety of wildlife, including large quantities of fish and many edible plants. In 1776 A.D. the Spanish arrived and established the Presidio, which was seized by the Mexicans in 1821, and then by the Americans in the Bear Flag Revolt in 1846 |

In 1912 the marsh was filled in to make way for the Panama Pacific International Exposition, which was held in 1915. In 1921 the U.S. Army turned a racetrack from the Exposition into an airfield, which they named after Major Dana Crissy. In 1994 Crissy was officially turned over the National Park Service; four years later, in 1998, restoration began on the marsh, and the restored marshes were opened to the public in 2001. |

Invasive Plants Invasive plants threaten to destroy the natural beauty of Crissy Field, as well as many other areas all over the world. Invasive plants are exactly what they sound like, plants from foreign places that take over and kill the local plants. This is not only bad for the other plants in the area, but also bad for the animals, as many invasive plants are toxic and inedible for the local wildlife. They also disrupt the diversity of a region, as they can soon completely wipe out other species of plants in the area leaving just foreign plants in a sparsely unpopulated area. |
