Natural Bridges State Beach Exploration

1a. Sign for Monarch Butterfly Natural Preserve and Resting Area

Thu, 24 May 2007 08:06:10 -0700

- In 1983, California State Parks made this monarch grove a natural preserve and sanctuary for these fragile world travelers. The Monarch Grove provides the ideal conditions for the butterflies, and for you to see them.

1b. Monarch Preserve Boardwalk

Thu, 24 May 2007 08:06:10 -0700

- Visitors can view the over-wintering Monarchs by walking down the park's wheelchair and stroller-accessible boardwalk to an observation deck in the eucalyptus grove.

1c. Monarchs and Eucalyptus Trees

Thu, 24 May 2007 08:06:10 -0700

- Lots of eucalyptus trees were imported from Australia in the 1850s with the hope that these fast-growing trees would provide lumber for coastal development. The splintery wood proved useless as lumber, but the long, slender leaves provided perfect spots for resting monarch butterflies.

1d. Red Gum Eucalyptus

Thu, 24 May 2007 08:06:10 -0700

- Can you spot the two different types of eucalyptus that grow in this park? Both have the aromatic oil with its distinctive odor. The leaves of the red gum (Eucalyptus rostrata) are about five inches long and narrow. Rain leaches acids out of eucalyptus and into the soil, keeping many other species from growing at the base of the trees.

1e. Blue Gum Eucalyptus

Thu, 24 May 2007 08:06:10 -0700

- The leaves of the blue gum eucalyptus (Eucalyptus globulus) are a little longer and wider. Butterflies love to cling to the long, narrow leaves. This variety also has large blue seedpods that have a distinctive cross on top-- making them look something like a button.

2a. Seasonal Pond

Thu, 24 May 2007 08:06:10 -0700

- During the winter, groundwater fills this half acre and turns it into a bustling habitat for red-winged blackbirds, belted kingfisher, American coot, American bittern, Sora, Virginia rails, and even great blue herons. Can you hear any frogs? That could be a Pacific chorus frog or a Red-legged frog.

2b. Prehistoric Benches

Thu, 24 May 2007 08:06:10 -0700

- These natural benches were formed a million years ago during the Pleistocene epoch. They provide a good resting spot for observing the plants, animals and insects that live in and around the pond.

2c. Duckweed

Thu, 24 May 2007 08:06:10 -0700

- These plants provide cover for nesting birds. The Central Coast Ohlone Indians relied on tule to make their houses, mats, boats, rope and clothing. Ponds like this one are home to one of the the smallest flowering plant-- a species of duckweed (Lemna sp.).

2d. Cattails

Thu, 24 May 2007 08:06:10 -0700

- Cattails were an important food source for the Ohlone-- everything from the roots to the fuzzy seeds is edible.

2e. Red-winged Blackbird

2f. Pacific Chorus Frog (Pseudacris regilla)

Thu, 24 May 2007 08:06:10 -0700

- P. regilla is the most commonly heard frog in this pond, and throughout California. Its call is known throughout the world because it is used so often in the movies. Image Source: Wikipedia

2g. American Coot (Fulica americana)

3a. Meadow Area

Thu, 24 May 2007 08:06:10 -0700

- Today's meadows are very different from the meadows the Ohlone knew. The Spanish missionaries converted open lands to cattle pasture in the late 18th century. The Europeans also brought nonnative meadow species, such as wild oats and other grasses, plantain, wild radish and wild mustard. Many of these plants now dominate the landscape.

3b. Wild Radish (Raphanus sativus)

Thu, 24 May 2007 08:06:10 -0700

- Related to the garden radish, the wild radish (Raphanus sativus) is easily identified by its soft yellow, white or purple flowers and pod-like capsules. Unlike the garden radish, the roots of the wild radish are too woody to eat.

3c. Plantain (Plantago Major)

Thu, 24 May 2007 08:06:10 -0700

- Early settlers in California recognized the medicinal properties of plantain (Plantago major). Applying a poultice made from the leaves to snake or insect bites removes toxins. You can also eat the leaves and seeds of this plant.

3d. Plantain (Plantago Major) flower

Thu, 24 May 2007 08:06:10 -0700

- The distinctive flower of plantain was a welcome sight to settlers and native inhabitants alike.

4a. Coyote Brush (Baccharis pilularis)

Thu, 24 May 2007 08:06:10 -0700

- The fluffy white flowers (not shown) on this densely growing shrub give the plant its name: coyote brush (Baccharis pilularis). It looks as though it has caught the downy fur of a passing coyote! This plant can grow in thin soil with little water. The wood burns easily, but the roots regenerate quickly after a fire.

4b. Poison Hemlock (Conium maculatum)

Thu, 24 May 2007 08:06:10 -0700

- Poison hemlock (Conium maculatum) is of European origin, and is related to carrots and parsnips. However, all parts of this plant are highly toxic.

4c. Poison Hemlock (Conium maculatum) stem

Thu, 24 May 2007 08:06:10 -0700

- The purplish patches on the stem are a distinguishing feature of the imported Poison hemlock. In ancient Greece hemlock tea was used for executions.

5a. Monterey Pine (Pinus radiata)

Thu, 24 May 2007 08:06:10 -0700

- How can you tell the age of a Monterey pine (Pinus radiata)? Count the whorls of existing branches and broken stubs extending from the trunk. Each year, a new whorl of branches emerges from the tree top. This species is restricted to the Central Coast. It not only can survive fires, it needs the heat to release its seeds, which then flourish in the scorched soil.

6a. Monterey Cypress (Cupressus macrocarpa)

Thu, 24 May 2007 08:06:10 -0700

- These Monterey cypress trees (Cupressus macrocarpa) have been sculpted by the wind. With one of the most restricted ranges of any tree in California, this species grows only in narrow strips along the Central Coast. Recognize it by looking at the female cones: they look like little soccer balls!

6b. Animal Tracks

Thu, 24 May 2007 08:06:10 -0700

- Can you tell who's been here? Look in the soft soil for signs of some of the park's inhabitants. See if you can tell the footprints of a skunk from those of a raccoon, or a cat from a fox. Image Source: Wikimedia

7a. Open Field

Thu, 24 May 2007 08:06:10 -0700

- The spot where you're standing might have been a luxury hotel, if early Santa Cruz settler Fred W. Swanton had had his way. The wealthy entrepreneur built the casino and boardwalk a few miles south. In 1881, he owned this land and planned to develop it before bankruptcy ended his dream. The State of California bought this land in 1933.

8a. Natural Bridge(s) in the distance

Thu, 24 May 2007 08:06:10 -0700

- Once there were three natural bridges carved by the waves out of the Santa Cruz mudstone. Town residents used to drive onto the bridges to picnic or have weddings. Human use, coupled with the pounding wind and waves, helped erode the formations. The first bridge fell in the early 1900s and the second in 1980 after a heavy storm.

9a. Moore Creek

Thu, 24 May 2007 08:06:10 -0700

- Moore Creek originates in the Santa Cruz Mountains and flows through the park out to the ocean. Water samples taken here show evidence of human contamination from industry and development.

9b. Ring-tailed Cat (Bassariscus astutus)

Thu, 24 May 2007 08:06:10 -0700

- The Ring-tailed cat ((Bassariscus astutus), also known as the ringtail or cacomistle, is an endangered nocturnal species related to the Raccoon. It has been sighted along upper Moore Creek. Further contamination of this water source could have dire consequences for this rare species. Image Source: Joachim S. Müller

10a. Ice Plant (Carpobrotus edulis)

Thu, 24 May 2007 08:06:10 -0700

- Hottentot Fig, also referred to as ice plant, is an introduced species that can tolerate high levels of salt. The crushed leaves may be used as a deodorant. Small mammals eat the fruit of the plant.
