Native Oaks Are a Valuable Resource

By Bob Mulvaney, Master Gardener


Native oaks are a vital and important component of the vegetation of California and in particular the Central Coast.  Oaks grow in a wide variety of habitats and help provide a distinctive character to our local landscape.

Not only are they beautiful to look at, but they also provide food and shelter for many wildlife species.  They stabilize soil and help counteract the "greenhouse effect" by taking up carbon dioxide and providing oxygen.

It is estimated that one or more species of oaks grow on over 20% of
California's 100 million acres of land.  Unfortunately, there are reports that some native oaks may not be regenerating very well in some locations.

Additionally, increased pressures from development, both residential and agricultural, have caused a loss of many of these noble trees.

The above factors raise concerns about the long term fate of this species.  The Native Tree Committee of the
County of San Luis Obispo is leading an effort to regenerate the native oaks in our county.

The Master Gardener Program has joined the committee in a joint venture to help regenerate Central Coast oaks.  We will soon be gathering acorns that will be propagated by students from Shandon and
Templeton High Schools.  The oak seedlings will then be planted and nurtured in various locales throughout San Luis Obispo County

The
University of California Cooperative Extension has a series of short pamphlets which discuss our native oaks.  These documents cover a wide range of topics from "How to Grow California Oaks”, Living Among the Oaks: A Management Guide for Landowners  and Living Among California’s Oaks.

Additional materials are available about irrigation or construction near existing oaks as well as companion planting under or around these venerable trees.

If you would like to request one of these publications or if you have any questions about oaks, please do not hesitate to contact us.  We look forward to hearing from you.

Until then, Good Gardening!
