Lagoon Trail Guide

  1. Cattails
  2. Cattails are near the trail growing in freshwater from the golf course. Notice the flat leaves and the cigar-like brown flowers.

  3. Wood Rat Nest
  4. Look in this patch of Arroyo Willows and Mulefat to see a wood rat den. Listen and look for the Bushtits (chitterling small birds).

  5. California Sagebrush
  6. This bush (smells like sage; scientific name: Artemisia) is the most common one of the plant community called Coastal Sage Scrub. It is green from winter to mid-summer, then brown and dead-looking the rest of the year. It was used by the Native Americans to repel insects in their beds and to camouflage body odor during hunting.

  7. Heron and Egret Nests
  8. Surprisingly, Great Blue Herons and both Snowy and Great Egrets build their nests in trees. Look for nests and birds in the eucalyptus trees.

  9. Pampas Grass
  10. One of the most invasive non-native plants is Pampas Grass. If not killed (like these herbicide-treated plants) or removed, they spread seeds from their fluffy flower heads.

  11. Tree Tobacco
  12. Hummingbirds love the long yellow flowers of this small tree, which blooms all year. The leaves are toxic.

  13. Geology
  14. This unconsolidated sediment is called the Bay Point Formation. It was deposited along the sides and bottom of an earlier lagoon, less than 1 million years ago, during the last ice age. This formation contains fossils of Scallops and Sea Pen shells.

    PLEASE, NO COLLECTING!

  15. Coastal Goldenbush
  16. This native plant is often found in the disturbed areas on either side of the trail. It has yellow flowers from mid-summer to fall, then dandelion-like seeds in winter. Thus, these plants are a source of food for birds when other plants are dormant.
