Our Mission: The Puente Hills Habitat Preservation Authority is dedicated to the acquisition, restoration, and management of open space in the Puente Hills for preservation of the land in perpetuity, with the primary purpose to protect the biological diversity.

When you visit nature, remember: it’s our shared responsibility to protect it for future generations. The Leave No Trace principles help us minimize our impact on the environment.

The Habitat Authority has hired extra help for the rangers with its efforts to close trails for health and safety of nearby communities. These security guards are positioned at Turnbull Canyon and Powder Canyon, and will be there 24/7 until the trails are reopened.

The trails are closed until further notice for public health and safety. Please check back for updates. Thank you for your understanding.

As we know, fire season is now year-round. To prepare, our rangers still have water pumps that carry 100-200 gallons of water on their vehicles. Learn more about the Habitat Authority’s fire preparedness here:
