Puente Hills Preserve News, April 2024

A Message from our Executive Director Andrea Gullo:

30 Years of Service, 1994-2024


This year we are celebrating our 30th anniversary of preserving the Puente Hills as a public agency. Since 1994, the Habitat Authority has been honored to play our role for nature and the public good. We hope to continue to do so for future generations to come as we explore future funding options to address a budget structural deficit that threatens the continuation of essential services. 


For three decades, the Habitat Authority is proud to have served by:


  • Protecting and managing the 3,880+ acre Puente Hills Preserve, implementing habitat restoration of over 312 acres, and partnering in building Los Angeles County’s first wildlife underpass.
  • Providing a 23-mile trail system (via six trailheads: Sycamore Canyon, Powder Canyon, Hellman Park, Arroyo Pescadero, Hacienda Hills, and Turnbull Canyon) for thousands of people to enjoy daily. 
  • Providing rangers that provide law enforcement and are trained in wildfire fighting, which contributes to the local communities’ quality of life and property values by keeping the hills clean and safe.
  • Contributing to our social fabric by providing a venue for our amazing volunteers to host public hikes each week for all to enjoy. 
  • Providing preventative brush clearance to protect local communities from wildfires.
  • Having provided outreach to over 33,000 youth and adults as a result of our educational efforts.

Trail Repair

The winter season brought a lot of rain, which the thirsty plants loved, but it also resulted in the need to repair many trails throughout the Preserve. We and our contractors have been hard at work clearing trails and making improvements especially along the Bob Henderson Loop Trail at the Arroyo Pescadero Trailhead, and along several trails in Powder Canyon. The repairs in Powder Canyon are ongoing through April. 

Protect Open Space

The Habitat Authority is exploring ways to preserve and enhance the beauty of the Puente Hills. Additional funding would assist first responders, maintain natural habitats, prevent homeless encampments, and support the work of park rangers. Click here to view social post.

California Bush Sunflower

Most people associate sunflowers with the large annual plants grown in gardens that produce delicious sunflower seeds. But Southern California is also home to other types of sunflowers, including the California bush sunflower (Encelia californica). This attractive shrub blooms cheerfully in the spring before going dormant by mid-summer. These sunflowers can be enjoyed along many trails in the Preserve at this time of year including at the Hacienda Hills Trailhead and Arroyo Pescadero Trailhead. Click here to view social post.


Some interesting facts about this species include:


  • Like garden sunflowers, California bush sunflower heads track the sun.
  • Each “sunflower” is actually made up of many individual flowers. The “petals” are ray flowers and the brownish center is made up of many disk flowers. This is a characteristic of the sunflower family: a cluster of flowers mimics a single flower.


“Where flowers bloom, so does hope.”
