Looking For Acorns

The Arroyo Seco Foundation Watershed program coordinator is sending out a call for acorns. He’s asking for residents to put in their refrigerator any acorns from a fruitful oak tree—especially those that are on a leaf-bearing twig—then send him an email at jonathan(at) or call 323.405.7326. They will arrange a pick up and then will nurse and nurture the acorns in their nursery.
He says they are particularly interested in acorns from the endangered Engelmann oak, which have a “distinctive grey/green leaf with an open airy canopy and mottled bark.”

The ASF is striving to re-open the Hahamongna Cooperative Nursery, which is run solely by volunteers and “has turned out thousands of trees for the parks and natural rural areas of Southern California in years past, and soon will be back in action.”
