Save the Engelmann Oak

The coast live oak is grand, but the Engelmann oak is truly spectacular. This oak was known as the Pasadena oak in Los Angeles County, but now it is threatened throughout its historic range.


It's Autumn —
and the Acorns are Falling

We need your help collecting acorns for Hahamongna Native Plant Nursery. If you know of a great Coast Live Oak or Engelmann Oak in your neighborhood, we would be very grateful if you could collect a bag of acorns for us to propagate at our nursery.
