Your guide to safely navigating our wildlife population
Castle Pines is lucky enough to have a thriving wildlife population, including deer, elk, bears, bobcats, mountain lions, snakes and coyotes. The city always seeks to achieve a balance between the importance of human safety and the native ecology of the region.
Below are resources and best practices for sharing the environment with our wild neighbors.
Incidents and Attacks
If you’ve seen or been involved in a wildlife incident or attack, notify Colorado Parks and Wildlife Northeast Region Service Center immediately.

I-25 Wildlife Exclusion Fence Project
The Colorado Department of Transportation (CDOT), Colorado Parks and Wildlife (CPW), the City of Castle Pines, the Town of Castle Rock and Douglas County are partnering to install 16 miles of wildlife fencing on the east and west side of I-25, from the Ridgegate exit (MM 192) in Lone Tree to the Meadows/Founders exit in Castle Rock (MM 184).

Coyotes are very adaptable and often thrive in urban areas. For more information about how the city responds to the local coyote population, check out the city’s Coyote Management Plan.
Bears are typically seen in our community during the summer and fall seasons. As winter approaches, they look for food sources to prepare for hibernation, and it’s easier to get calories from trash cans than from foraging in the wild—which is why we ask residents to follow these guidelines:
- Do not leave trash or trash cans outside overnight.
- Properly store pet food and bird seed.
- Burn food off of barbecue grills and clean after use.
- Keep all bear-accessible windows and doors closed and locked, including home, garage and vehicle doors.
- Don’t leave food, trash, coolers, air fresheners or anything that smells in your vehicle.
- Pick fruit before it ripens, and clean up fallen fruit.
- For more information about living with bears, visit the Colorado Parks and Wildlife page.
Beekeeping is allowed within populated areas of the City (see ordinance 17-03 for details).
Bee swarms are a natural phenomenon that occurs when a hive becomes overcrowded and the old queen and about half of the original hive leaves to find a new home.
- In Colorado, bees swarm from April through the end of summer, with May and June being the busiest months.
- Swarms are generally quite docile and will eventually leave on their own when a new hive location has been found.
- If you prefer to have a swarm professionally removed, call the Colorado Swarm Hotline at 1-844-779-2337 (1-844-SPY-BEES).
For more information about bees, visit the Colorado State Beekeeper Association website.
The most common large snakes you'll find in the area are prairie rattlesnakes and bull snakes. Rattlesnakes are venomous while bull snakes are not -- but both can bite and cause a medical issue.
- Stay on designated paths or walkways to avoid a snake encounter
- Snakes will not attack if they don’t feel threatened. If you encounter a snake, give it a wide berth or turn in the opposite direction.
- If you’ve been bitten by a snake, seek medical attention immediately.

To reduce the risk of problems with mountain lions on or near your property, we urge you to follow these simple precautions:
- Install outside lighting. Light areas where you walk so you could see a lion if one were present.
- Closely supervise children whenever they play outdoors. Make sure children are inside before dusk and not outside before dawn. Talk with children about lions and teach them what to do if they meet one.
- Landscape or remove vegetation to eliminate hiding places for lions, especially around children's play areas. Make it difficult for lions to approach unseen.
- Planting non-native shrubs and plants that deer often prefer to eat encourages wildlife to come onto your property. Predators follow prey. Don't feed any wildlife!
- Keep your pet under control. Roaming pets are easy prey and can attract lions. Bring pets in at night. If you leave your pet outside, keep it in a kennel with a secure top.
- Don't feed pets outside; this can attract raccoons and other animals that are eaten by lions. Store all garbage securely.
- Place livestock in enclosed sheds or barns at night. Close doors to all outbuildings since inquisitive lions may go inside for a look.
- Encourage your neighbors to follow these simple precautions. Prevention is far better than a possible lion confrontation.
