With an estimated population of 400-500 individuals, these bears have been steadily increasing in numbers since the late 1970s. They inhabit diverse habitats within the forest, from lower foothills to higher mountainous areas, and have been known to venture into urban areas in search of food. This guide provides essential information about black bears in the Angeles National Forest, including their behavior, habitat, and safety tips for visitors.

- Total population: 400-500 individuals
- Growth rate: Approximately 5% annually
- Distribution: Throughout the San Gabriel Mountains and surrounding foothills
This increase in population has led to more frequent sightings, even in areas not typically associated with bear habitats.
Where Have Recent Black Bear Sightings Occurred?
Recent black bear sightings have expanded beyond their traditional habitats:
- San Fernando Valley
- Santa Monica Mountains
- Urban-wildland interfaces around the forest
One notable example is a tagged bear known as Yellow 2291, which has been spotted in various locations after traveling long distances from its original habitat in the San Gabriel Mountains foothills.
What Are the Feeding Habits of Black Bears in Angeles National Forest?
