While bears are not typical inhabitants of Portland’s urban core, they occasionally venture into suburban areas, especially those bordering natural habitats. This occurs as bears search for food or expand their territories. Understanding bear behavior and knowing how to react if you encounter one can help ensure safety for both humans and wildlife.
Bear Presence in and Around Portland
Oregon is home to an estimated 25,000 to 30,000 black bears, the only bear species found in the state. These bears are widely distributed across Oregon, with concentrations in the Coast and Cascade ranges, as well as the Blue Mountains. Black bears are adaptable, thriving in dense forests, along trails, and near streams.
Portland’s unique geography, particularly its proximity to large natural areas like Forest Park, makes occasional bear sightings possible. Forest Park, for example, experienced multiple black bear sightings in May 2023. Bears may enter residential zones when natural food sources are scarce, especially after hibernation, or when easily accessible human-provided food attracts them.
Understanding Bear Behavior and Preventing Encounters
Black bears are naturally wary of humans, but their exceptional sense of smell allows them to detect food sources from considerable distances. This keen sense can draw them into populated areas if unsecured attractants are present. Common items that lure bears include household garbage, pet food left outdoors, bird feeders, fallen fruit, beehives, and barbecue grills.
To prevent encounters, securing potential food sources is important. Residents should store garbage in bear-resistant containers or keep them indoors until pickup morning. Removing bird feeders when bears are active, feeding pets indoors, and cleaning barbecue grills after each use can deter bears. Fallen fruit should be collected, and compost piles, especially those with food scraps, should be enclosed.
What to Do If You Encounter a Bear
Encountering a bear can be startling, but staying calm is crucial. If you see a bear before it notices you, remain still, then quietly move away without approaching. If a bear does see you, avoid direct eye contact, as this can be perceived as a challenge.
Never run from a bear, as this may trigger a chase response. Instead, make yourself appear as large as possible by waving your arms or holding up a coat, and make noise by yelling “Hey bear!” or speaking firmly. Slowly back away while facing the bear, giving it space to escape. In the rare event a black bear makes physical contact, fight back aggressively.
Report bear sightings, especially those involving unusual behavior or a lack of wariness around humans, to the Oregon Department of Fish and Wildlife (ODFW). If a bear poses an immediate threat, contact 911.
