Get ready for Coastal Cleanup Day 2007

Shipwrecked
Trash on our beautiful beach


Sunday, September 15, 2007 is California's Coastal Cleanup Day.

Why not devote half an hour to making Long Beach a more beautiful place? All you have to do is show up, and pick up trash you find along the beach.

Something is going on at nearly every stretch of the beach in Long Beach. In addition, there are inland sites along the Los Angeles River, and at the ponds in El Dorado Park. Remember: Trash anywhere on the strees in Long Beach will eventually wind up on the coast! So you can clean up the coast anywhere in the City. I'll post details about exact locations once they are known.

Coastal Cleanup Day is organized by the California Coastal Comission.

I participated in this event in 2006 at Alamitos Beach. So what did I think of it?

-Yes, it's kind of futile to think that one day of cleaning will have much of an impact. In fact, the beach didn't look any cleaner immediately after we finished.
-Some people don't quite get it. Some jerk dumped piles of moldy bread on the beach, and none of the volunteers thought it was littering until I pointed out to them that food on the beach attracts lots of rats.
-It's a great experience in self-education. There is FAR more litter on our beach than you might ever expect. And yes, it is all harmful to wildlife.
-It's a great public eductaion. If a man or woman sees hundreds of people cleaning up the beach, they may realize that the beach is something to value. Usually, people are ashamed to think someone else is cleaning up after them, and they will be more responsible with their own trash.
-They ask you to tally up all the pieces of trash you pick up. I think it's a waste of time and stupid. But for some people, it makes the task fun. I "guestimated" my numbers at the end. How many cigarette butts did you pick up? Eight billion?

By the way, they usually have awesome signs for the event. Last year's featured these cool wildlife cards:

News: Fire at El Dorado Nature Center

The Press Telegram reports that firefighters put out a small fire near the Nature Center on the evening of August 19. [article]

Hot embers from an unknown source ignited the compost bin, although arson hasn't been ruled out.

However, damage to property appears to have been minimal, and none of the animals in the building were harmed.

Although brush fires were a historically common event in southern California, and most plants and animals are very well adapted to it, the small size of El Dorado park means that wildlife are very vulernable to fires here. A large enough blaze could wipe out an entire population

El Dorado Regional Park

CommunityWalk Map - El Dorado

Without a doubt, El Dorado represents the most siginificant inland natural area in Long Beach. Over 100 acres of natural habitats are maintained within the 400 acre park (the rest of the park being devoted to active and passive recreation).

El Dorado Nature Center
El Dorado Park has a great Nature Center with all sorts of displays and activites for children. They also organize events for adults, such as night-walks and bird ID classes. Unfortunately, the Nature Center has been recently vandalized by some very inconsiderate people. (What kind of person would smash a urinal?)

El Dorado Park is large enough to have honest-to-goodness trails! Three, in fact.

Paved trail
The shortest trail is only 1/4 a mile, and is entirely paved, with railing. This trail winds through a dense forest near the Nature Center, and is completely accessible to wheelchairs.

In forests, trees grow densley, shading out most of the sunlight from the forest floor. (In contrast, there's more space between the trees in a woodland--see below.) Forests are uncommon in the lower elevations of Southern California, because few areas have enough soil moisture year-round.

Sun through alder leaves
The leaves of this white alder (Alnus rhombifolia) catch what little light makes it through the dense upper canopy of leaves.

The lower levels of a forest is generally full of saplings and vince that get just enough sunlight to keep themselves alive. These plants are waiting for the bigger shade-producing trees to fall over or die, flooding the floor with sunlight. Until then, they simply wait and try to stay alive.

Animal life is bustling here. The thick growths of branches are festooned with spiderwebs, which catch all sorts of insects.

A spider in its web waits for its next meal. The carcass of a damselfly shows that the spider has been eating well.

Western fence lizard
Western fence lizards (Sceloporus occidentalis are common in nearly every part of the park, but you are most keenly aware of them in the forest, where they rustle loudly in the dried leaves.

The end of the paved trail (or entrance, depending on which way you do the loop) takes you through a small open grassland, where many native wildflowers were recently planted (as well as a few non-native ones, for some reason).

Sticky monkey flowerSticky monkey flower
Sticky monkey flower (Mimulus aurantiacus) is one of the showiest native wildflowers. It ranges in color from yellow to red.

Cliff buckwheat
Several species of buckwheat grow in the park. This photo is sea cliff buckwheat (Eriogonum parvifolium). Nearby, you can find California buckwheat (E. fasciculatum, and giant buckwheat (E. giganteum).

Woolly bluecurls
Woolly bluecurls (Trichostema lanatum) has bizarre and striking flowers.

There are two longer trails (1 mile and 2 mile), which, though unpaved, are still extremely easy. The longer trail passes through some unshaded areas, so be sure to wear sun protection.

Thanks to its size, touring El Dorado will show you a large variety of habitats: oak woodlands, forest, coastal sage-scrub, grassland, chaparral. In addition, there are several different aquatic habitats: two large ponds, a stream connecting them, plus their fringing wetlands.

All paths take you near the two large ponds in the pond, as well as the stream connecting them.

Turtles are among the most conspicuous wildlife you will see in the ponds.

Turtle floats near the nature center:
Turtle floats
Although the floats may be somewhat garish, they provide excellent basking for the ponds' turtles (mostly exotic red-eared sliders). This allows them to be viewed close to shore by children, but still safe and secure from predators.

Slider and map turtle
Red-eared slider (Trachemys scripta elegans), left, and Ouachita map turtle (Graptemys ouachitensis), right. Both are nonnative turtles widely sold in the pet trade.

Typically, you will see many red-eared sliders (Trachemys scripta elegans). However, I saw one Ouachita map turtle (Graptemys ouachitensis) among them. Both are probably escaped pets, although the sliders have undoubtedly established a stable population in the park.

Black phoebes
Two black phoebes (Sayornis nigricans) hang out near the water's edge.

Lots of birdlife is attracted to the wetland. Fly-catchers, such as these black phoebes (Sayornis nigricans) perch near the water and catch flying insects "on-the-wing." Pretty impressive to watch!

In addition to the typical wetland cattails, rushes, and sedges, you can find some unusual plants growing near the pond:

Yerba mansa
Lizard tail, or Yerba mansa (Anemopsis californica)

Oak Woodland:
El Dorado Park - Oak woodland

Coast live oaks (Quercus agrifolia) intersperse with willows, alders, and other trees and shrubs to form small, open woodlands. Unlike a forest, woodlands have well-spaced trees, and it is generally easy to see through the vegetation. Smaller herbaceous plants may grow densely in the understory.

Coastal sage-scrub

The El Dorado chapter of the Audubon Society maintains a check-list of birds for this park.

Although much of the park has native vegetation, there are quite a few nonnative ornamental plants too. I'm not sure if the nonnatives that have been planted are considered invasive and a threat to Long Beach's wildlands, but I would prefer if the park remained a sanctuary for the native plants of California.

Plans are in development to create treatment and habitat wetlands in the more developed portions of El Dorado between Carson Street and Spring Street. This project would expand wetland and riparian habitat in the park, and prevent pollution from entering the San Gabriel River.

To get to the Nature Center, take the 102 bus (M-F) or the 173, and walk east down Spring Street from Studebaker.
