The Heath and Marjorie Angelo Coast Range Reserve protects 7,660 acres of  the upper watershed of South Fork of the Eel River in Mendocino County for university-level teaching and research. The Angelo Coast Range Reserve was the first gift to The Nature Conservancy west of the Mississippi, and for many years, the largest (see site history). Today, it is one of 39 protected natural areas  in the University of California Natural Reserve System, and is managed through the U.C. Berkeley campus.

Since Heath and Margorie Angelo protected their land in the 1930s, the population of California has increased over six-fold.  The Angelo gift, along with the 17 sq. km Elder Creek basin (designated as an area of critical ecological concern by the Bureau of Land Management)  together constitute one of the largest continuous tracts of undeveloped coastal conifer forest remaining in California.  The reserve protects 5 km of the upper South Fork Eel River, four undisturbed tributary watersheds, mixed conifer-broad-leaf forests, meadows on river terraces, and bands of chaparral at higher elevations.

Angelo Reserve is located in the Eel River Watershed which spans 3 counties in coastal northern California.

Partnership of ERRP and Angelo ERCZO in monitoring cyanobacteria blooms

I wanted to draw attention to the commendation of the Humboldt Count Board of Supervisors commendation of the partnership of the Eel River Recovery Project and UC Berkeley’s Angelo Reserve (mainly the efforts of Keith Bouma Gregson) in drawing together residents and researchers to locate and watch toxic cyanobacteria, and investigate the environmental changes that may be supporting more frequent, expansive, or problematic blooms of these potentially toxic ‘bluegreen algae’.  Pat Higgins, Managing Director of ERRP, is quoted as saying “UC …kind of adopted us and said ‘We want to come and do algae studies on the Eel and use your volunteers’….”  but we Angelinos feel the other way around, very grateful for all that we are learning from the ERRP volunteers about the history and current environmental trends in the larger Eel River basin.  It isn’t that common that academic field biologists find such amazing partners and friends when trying to work on larger scale environmental problems–many, many thanks to ERRP for their partnership, energy, organization, field skills, and deep commitment to the future of the Eel.
