An excerpt from the article 17 facts about California poppy

Among other wildflowers, on over 1700 acres (7,2 km2), vast fields full of poppies are growing there. The reserve, located in Los Angeles County, was established in 1976 and is under the management of the California Department of Parks.

The plants are not irrigated or fertilized, leaving the ecosystem intact.  Animals are also not allowed in the park, except for service dogs. For visitors, there are over 7 miles (11 kilometers) of tracks for guests, including wheelchair-accessible trails. Despite the abundance of plants, picking flowers is prohibited.
