Collecting Cuttings for Hahamongna Nursery
Volunteers are collecting toyon cuttings for propagation at the Hahamongna Cooperative Nursery.

Here's a great way for you to get involved in protecting and restoring the environment.

We need your help at the new Hahamongna nursery! We propagate native trees and plants, pot up seedlings, and there's always more weeding to tackle. Then we head out into the Arroyo Seco Canyon to use the plants in a stream restoration program in the Arroyo Seco Canyon just above Jet Propulsion Laboratory in the foothills of the San Gabriel Mountains!

Hahamongna is that special place where the Arroyo Seco River comes out to the majestic San Gabriel Mountains. The Arroyo Seco Foundation is working with the City of Pasadena to restore and enhance the Arroyo Seco and its watershed.

Native plants -- like oaks, willows, laurel sumac, buckwheat and scores of other species -- are vital to the Arroyo stream and to our local environment. They provide the habitat and conditions for wildlife and a healthy ecosystem. You will be able to learn about these plants and their importance in preserving and enhancing our communities and the environment. You'll learn the importance of stewardship and "giving back," while you watch your plants grow and thrive.

This kind of stewardship is the path to preserve the past and to ensure a future of a healthy land, water and air for current and future generations. And it's a lot of fun and very rewarding.

Come share in this great program.
