Help Save the Spectacular Engelmann Oak
are truly spectacular trees, but in our area the grandest is the
rare Engelmann Oak (quercus engelmannii). Most oaks we see on the coastal plain of Southern California
are the trademark Coast Live Oak (quercus agrifolia). Itís dark green leaves and
dense foliage can be spotted everywhere.
Coast Live Oak is an impressive tree, but the majesty of the Engelmann can
take your breath away. Their large twisted spreading limbs generally form a sparse crown.
Their gray/green leaves are more elliptical or oval than the Coast Live Oaks, and their
acorns more stubby. They often reside near Coast Live Oaks and Sycamores.
separate species, Engelmann Oaks only exist in a narrow band that
stretches along the foothills of Southern California from Pasadena
down through Orange and San Diego County into Baja California. They need to be twenty miles or more away from the ocean at
an elevation of 500-4000 feet.
Southern California these spectacular trees have had a hard time because the mesas
on which they are usually found are also ideal sites for homes.
Oaks are probably the most imperiled of all tree oaks and are one of the
most endangered natural plant communities in California.
are still some Engelmann Oak woodlands in San Diego County, and they steal
the show on the Santa Rosa Plateau in Riverside County.
the Fall the Arroyo Seco Foundation collects Engelmann acorns to propagate
seedlings at our nursery. In
recent years we have planted or given away hundreds of these great trees.
