Arroyos & Foothills Conservancy conserves, protects, and stewards natural open space to enhance connectivity and biodiversity.

Our Work

Arroyos & Foothills Conservancy (AFC) began in 2000 as a grassroots organization committed to conservation in Altadena. Over the last 25 years we have grown into a land conservancy at the forefront of urban conservation.

We work with urgency to save and connect land for wildlife and to restore natural habitat with native plants. We also provide free environmental education to communities across Los Angeles County to nurture a greater connection to nature. 

The San Gabriel Mountains are a vast natural landscape with a well functioning ecosystem. The San Rafael Hills, Verdugo Mountains, Debs Park, and Griffith Park are islands of native habitat surrounded by urbanization that need to be reconnected with the San Gabriels if they are to sustain healthy and diverse natural populations of wildlife and native plants.  AFC is working to connect these islands of habitat via wildlife corridors. This work of reestablishing connectivity is necessary for wildlife to find food, water, shelter, and mates. It also allows these special urban habitats to adapt to climate change. 

Wildlife corridors provide passageways suitable for the movement and dispersal of wildlife, including mammals, birds, butterflies, insects, and native plants.

AFC Properties

AFC currently owns 19 properties — over 92 acres — in Southern California.

Using an original land-prioritization matrix tool, we strategically acquire land with the highest ecological value. Some properties we save from development and passively manage as wildlife corridors; these can be as small as 1 acre or less.

On other larger properties, we restore native habitat and form a local community “Friends” group to manage the land and ensure it becomes a community resource — we call these properties Preserves.  Our six Preserves are located in Altadena, Pasadena, Glendale, and La Crescenta.

Explore our conservation region and the properties we own and steward using the map below.

Los Angeles is only 1 of 2 megacities (Mumbai, India is the other) where large predatory cats live in an urban setting.

Living with Wildlife

Living in the urban-wildland interface — where vast areas of natural open space meet human development — means we share our neighborhoods with wildlife of all sizes and species. 

To be respectful neighbors means making decisions that benefit all life. This could look like removing fences in your yard to allow for wildlife passage, utilizing native plant landscaping, or learning how we can maintain healthy ecosystems.

Conservation is a team effort. To make meaningful change for wildlife we must work together to protect native habitat.

  • Today is the International Day for Biological Diversity! 🌎

Since 1993, this UN-designated day has brought attention to the importance of protecting nature. The theme this year is acting locally for global impact — and AFC is proud to be doing that every day.

We live in one of only 36 biodiversity hot spots in the world, which means that the species and ecosystems right here contribute to the health of global biodiversity as a whole. Many of the 4,000 species of plants and animals in Los Angeles County exist nowhere else on Earth. When their habitat is lost here, they may disappear forever.

But there is hope: join this global movement by making a difference right outside your front door. Helping out with habitat restoration, doing community outreach, or volunteering to study urban wildlife movement has a vital impact. Please consider donating to our mission: a gift to AFC helps us protect local land from development, restore native habitat for wildlife, and educate the community on the importance of open space.

  • A mountain lion we recently captured on our Millard Canyon Preserve trail camera. 🐾 Millard is a post-fire sanctuary for wildlife in Altadena. In an area surrounded by development and human activity, it's a place of refuge for animals traveling through the area. In this video you can hear and see the rushing stream that is so vital to the sensitive species that call Millard home. ⁠

  • The health of our local ecosystems depend first on land conservation, and then on the long-term stewardship that follows. In this restoration case study you’ll read how our restoration work adapts to the evolving condition of our Preserves — which, like Rubio Canyon, can change overnight. 

Before the Eaton Fire tore through Rubio Canyon Preserve in January 2025, AFC and the Friends of Rubio regularly maintained hiking trails and removed invasive plants. We were also working on a long-term project to develop an outdoor education center at the Preserve. But after the fire, the needs of the land changed, and so did our stewardship tactics.
