In the 1940s, a California landowner released about three dozen zoo deer at Point Reyes for hunting; by 2002, the two non-native herds had grown to roughly 1,100 animals

Point Reyes National Seashore grapples with the ecological fallout from non-native deer species that were introduced in the 1940s. These deer compete aggressively with native wildlife, disrupting the delicate balance of the ecosystem. To address this, management strategies have been in place since 2007, aimed at curbing the populations of fallow and axis deer.
