The title says it all! It is amazing how particular secluded areas with their own environmental underpinning often are habitats for unusual plants. This program will show several of the odd or rare habitats that we have in and around Orange County and the resulting plants that occur in those places. In essence, unusual habitats mean unusual plants. We will discuss and show photos of local vernal pools, waterfalls, mima mounds, serpentine outcrops, rock cliffs, maritime chaparral, San Onofre breccia, mountain peaks and so forth. For each location we will profile a few of the rare plants that occur in these places, emphasizing the strong connection between habitat and plants.
Who else to show us some of the unusual plants growing in unusual spots in OC but our intrepid adventurer, Ron Vanderhoff! Ron has been hunting the normal and unusual plants of our region for decades and is certainly a native plant expert as anyone who follows his exploits on Facebook knows. He is an OC CNPS board member and actively involved in Chapter Field Trips, Invasive Plants, Conservation and the Rare Plant Committee. He serves on several regional and state Native Plant and conservation committees and is a contributor to The Wildflowers of Orange County and the Santa Ana Mountains and other publications. He is the Vice President of Roger’s Gardens in Newport Beach.
WELCOME to Nick Jensen, CNPS’ brand-new SoCal Conservation Analyst! His job is to bolster the efforts of the SoCal chapters’ volunteers, participate in ongoing collaborative planning efforts with CNPS’ partner organizations, and form new coalitions to ensure inclusion of underrepresented and non-traditional partners. He is the lead CNPS staff person covering conservation advocacy across the 11 Southern California Chapters. This area covers 10 counties and is home to 25 million Californians (64% of the state’s population), with an additional 3 million people in Baja California, Mexico. A BIG job!
VEGETATION TREATMENT PROGRAM
The CA Board of Forestry and Fire Protection (= CalFire) has reissued the DEIR for its proposed Vegetation Treatment Program (VTP), which aims to “treat” (withprescribed fire, mastication and/or herbicides) for “fire resistance” every bit of California’s State Responsibility Lands (SRL)—including in OC.
OC’s SRL are mostly the unincorporated areas in the foothills: i.e. our Wilderness and Regional Parks and Reserve areas. “Treatment” seems to mean cutting and maintaining fuelbreaks along every ridgeline. This is contrary to research that shows that the presence of a fuelbreak, in and of itself, doesn’t stop a fire from spreading; a fuelbreak’s main value is in giving firefighters a place to group (Syphard et al, 2012). A map showing OC’s SRL is Appendix A2.9 in http://bofdata.fire.ca.gov/board_committees/resource_protection_committee/current_projects/vegetation_treatment_program_environmental_impact_report_(vtpeir)/. The map has to be enlarged at least 400% to see the squiggly gray lines that denote the proposed fuelbreaks. Such extensive vegetation manipulation would result in:
1. Islands of CSS and chaparral in a matrix of grassy/weedy strips of fuelbreak.
2. A huge habitat disruption and loss for the myriad birds, insects and small animals that live within CSS and chaparral.
3. A huge increase in disturbance, wide open to invasive non-natives.
Native Gardeners Corner—Tips, Tricks and Techniques This column was first published in the January/February 2010 issue. The subject is timely as despite the absence of rain, we are still in prime planting season. The question was: “Which native plant would you confidently recommend for use in clay soil?”
Gene Ratcliffe—I vote for Festuca californica (California Fescue), a great evergreen grass that does well in heavy clay and even part shade, midway in size between the Nassellas and Muhlenbergia.
Celia Kutcher—Best shrub for clay soil on slopes within a few miles of the coast: Rhus integrifolia (Lemonadeberry). Best for clay soil flatlands: Nassella spp (Needlegrass species). & some other bunchgrasses. But it depends on how clayAey & how alkaline.
Alan Lindsay—The soil in my garden is clay, hard as a rock when it is dry. I have just one Chamise that thrives no matter what I do to it. It's been stepped on and broken, gone without water for an entire summer, and it keeps coming back. I believe its botanical name is Adenostoma fasiculatum var prostratum, which Tree of Life sells as Adenostoma fasciculatum 'Nicolas.' Mine has never gotten more than 3 feet high with a spread of 6 feet. The bloom is nothing to rave about but is abundant for a couple of months and its foliage is always dark green. I think this prostrate Chamise is overlooked as a landscaping plant, especially in clay soil.
Nancy Heuler—Fragaria chiloensis and/or Fragaria californica.
Greg Rubin—Some outstanding performers in clay include Baccharis 'Pigeon Point', Erigeron(glaucus (Beach Daisy), many Sages (S.(leucophylla,(S.(brandeegii,(S.(spathacea,(S.(apiana), many Buckwheats (Eriogonum sp)., Manzanitas (Arctostaphylos) such as 'Louis Edmunds’, ‘Sunset’, ‘Carmel Sur’, ‘Austin Griffith’, ‘Dr. Hurd’, ‘Howard McMinn', California Lilacs (Ceanothus) like 'Joyce Coulter’, ‘Frosty Blue’, ‘Blue Jeans’, ‘Ray Hartman’, ‘Yankee Point’, as well as California Fuchsia (Epilobium, Zauschneria sp).
