Enjoy a Native Plant Food Tasting on This Hahamongna Watershed Park Hike

Published on Jul 6, 2022

The Arroyo Seco Foundation, in partnership with the Altadena Library District, will lead a hike through the Hahamongna Watershed Park in Pasadena on Friday, July 8, 9 to 11 a.m. 

In this “Meet Us @ the Trails” hike, participants are expected to learn more about California edible and medicinal plants and enjoy a native plant food tasting. 

The Hahamongna Watershed Park is where the Arroyo Seco channel flows between the Jet Propulsion Laboratory (JPL) bridge and Devil’s Gate Dam. The watershed park provides multiple benefits that include water supply augmentation; flood water, sediment and debris capture and storage; passive and active recreation, and native ecosystem habitats. 

The Arroyo Seco Foundation (ASF), a community-based nonprofit organization, has been leading watershed management and environmental stewardship in Southern California for over 25 years. It is particularly dedicated to championing the Arroyo Seco, Southern California’s most celebrated canyon and a critical link from the Angeles National Forest in the San Gabriel Mountains to the Los Angeles River through the communities of Pasadena, La Canada Flintridge,  Altadena, South Pasadena and northeast Los Angeles. 

The Foundation advocates for an integrated, harmonious approach to watershed and flood management, water conservation, habitat enhancement, and the expansion of recreational opportunities. Through action projects, recreation, and environmental awareness activities, ASF involves the residents and organizations in Southern California in a campaign to reforest the Arroyo Seco, the San Gabriel Mountains and the neighboring urban landscape with native shrubs and trees.

ASF also operates Hahamongna Native Plant Nursery in the watershed park at the foot of the San Gabriel Mountains to produce high-quality native plants for habitat restoration and conservation landscaping.

Space is limited for the hike on Friday, and registration for each person is required. Registered participants will receive a trail guide and will be required to fill out a waiver of liability the morning of the hike.
