Plant Communities At The SRP: Plant Distribution

• Thus: common species are rare; rare species are common.

• Note that there may be thousands of individuals of a rare species where it grows.

  Example: our two most common tarweeds, San Diego tarweed (Hemizonia paniculata) and sticky tarweed (Holocarpha virgata ssp. elongata), are only found on the SRP trails out of the 90 trails I've covered in Southern California. Yet our most uncommon tarweed here, slender tarweed, Hemizonia fasciculata, is found in great abundance across Southern California!
