Madrona Marsh

Freshwater wetlands in southern California have been shrinking for a long time, ever since draining them for development became profitable. Kudos, then, to the city of Torrance, California for preserving, and even enhancing, a wildlife haven called Madrona Marsh. The city park is named not for any madrone trees on the property, but for a neighborhood road, one of many named after various types of trees.

I had the pleasure of visiting the park on May 17 with my friends Kim Moore and Emile Feisler. Emile has been documenting the flora and fauna of the park in images for several years. We managed to add at least one new organism to his list while on our outing.

Like most parks in the Greater Los Angeles area, this one comes complete with a nature center. The displays were museum quality, and the building also had meeting space, a library, and offices. Across the street from the nature center is the actual preserve, fenced at present, the gate locked in off-hours.

The morning started under overcast skies leftover from rain the night before, but the clouds eventually gave way to a bright, sunny afternoon. Inclement weather by human standards is often just perfect for other organisms, though, and we found plenty of insects, birds, and other animals. One of the first birds we saw was a female Blue Grosebeak, in fact.

The marsh is actually a vernal wetland, fed by rains in the winter and spring. By the end of August the pan is dry, and remains so until the rains resume. This cyclic phenomenon means plants and animals must adapt to annual extremes of wet and dry. The area is also a “back dune” habitat that is part of the extensive El Segundo Sand Dune System. You would be hard pressed to find any physical feature resembling a dune, however.

Unfortunately, the preserve is not immune from non-native species, and in fact that is what dominates the landscape in many places. Argentine Ants have displaced most of the native ants, for example. There is also a leaf beetle from Australia that feeds voraciously on the equally-invasive eucalyptus trees.

The human history of the marsh has been varied. Native Americans and early settlers utilized the natural resources of the area. Since the 1920s, the marsh was used for oil recovery (southern California is studded with tar pits, not just the famous La Brea Tar Pits). Ironically, petroleum salvaging kept the area protected from commercial development. The Friends of Madrona Marsh, a non-profit organization established in 1971, worked with other community groups to galvanize support for saving the marsh as a wildlife habitat and passive recreation site. Lobbying efforts and legal wrangling paid off with the dedication of of 35 acres. Later, state funds were allocated to purchase another eight-and-a half acres. The City of Torrance took over stewardship of the park in 1986, helping to stave-off development as part of Park del Amo.

I highly recommend visiting Madrona Marsh. Keep an eye out for waterfowl and other birds, as well as Pacific Treefrogs, dragonflies and damselflies, and Fox Squirrels among the other wild animals that call this place home.

Point Vincente Interpretive Center

One of the points of interest that I visited in southern California last month was the Point Vincente Interpretive Center in the City of Rancho Palos Verdes. This building, originally opened in 1984, was expanded and re-opened in 2006. While the focus of the center is the migration of the Pacific Gray Whale, there is much more to the facility.

It is surprising and pleasing to see that the majority of interpretive centers in southern California are city parks, rather than county, state, or privately-run. I think it improves civic pride and helps bond residents when they have a real public attraction to take ownership of. Like many of the centers in the Greater Los Angeles area, this one has art and landscaping around the exterior that creates an aesthetically-pleasing first impression.

Once inside, the first thing one sees is a open habitat diorama of the Palos Verdes Peninsula, and a fiberglass model of a Pacific Gray Whale suspended from the ceiling. A gift shop is on your immediate right, beyond which is the front desk, manned by both staff and volunteers. On our visit we were greeted by a volunteer anxious to explain the unique geology of the peninsula. This point of land is a tectonic fault block that has risen from the sea floor within the last two million years. That is quite recent by geologic standards. It was actually uplifted twice, with pronounced erosion in the interim, and obvious erosion visible today. Continual landslides make traversing the peninsula, even by vehicle, a bit dicey.

A good portion of the exhibit space in the center is devoted to man’s relationship to marine mammals, and whales in particular. Many historical artifacts related to whaling are on display, but equal time is given to the evolution of public opinion regarding cetaceans, and how research on these leviathans has progressed. It is quite an impressive collection considering how local the facility is.

Another surprise was the exhibit on the previous tenant of this piece of real estate. Remember Marineland of the Pacific? I recall it from my childhood. Many of my friends in elementary school made it down to that aquarium/theme park, though I never did. I had always thought that Marineland became Sea World, and indeed the owners of Sea World purchased Marineland in 1987, shutting it down shortly thereafter. The orcas, porpoises, and other animal performers were relocated to the San Diego park. The oceanarium known as Marineland had a good run, though, having opened in 1954.

Back outside, the gardens surrounding the nature center along the edge of the bluff attract a variety of insect and bird life. The behavior of wind and air currents along the bluff also means this is a premiere spot for watching soaring seabirds, especially Brown Pelicans. The odd Red-tailed Hawk may join them, spiraling on the thermals that seem to originate there.

I highly recommend a visit to this landmark the next time you find yourself in the vicinity of Los Angeles. Remember that the Pacific Gray Whale migration usually occurs from December through April. The bluff offers a spectacular view of the ocean below, the kelp forests waving in the crests and troughs of the tides. Whales would be easily visible, too.

Wildflowers of Charmlee

I have to start by thanking Kim Moore and Emile Fiesler for offering their expertise on our hikes through various southern California parks last month. As promised, here is a little sample of the wildflowers we saw at Charmlee Wilderness Park in Malibu.

Besides the profusion of Bush Monkeyflower, Mimulus aurantiacus, perhaps the most abundant, and certainly fragrant, flowering plant was Purple Sage, Salvia leucophylla. The scent was quite overwhelming, but in a pleasant, intoxicating way. It can bloom anytime between May and July (our hike was on May 19), and is commonly seen in coastal sage scrub habitat, oddly enough.

This was not the only species of sage to be found at Charmlee, either. The amazing Crimson Pitcher Sage, Salvia spathacea, also goes by the name Hummingbird Sage. Indeed, the red flowers must be a real draw for those nectar-feeding birds. It blooms from March to May in chaparral, coastal sage scrub, and oak woodlands. Sages are in the mint family, by the way.

Another fairly common plant was Spreading Phlox, Phlox diffusa. These are pretty large flowers compared to what I think of when I think of a Phlox. This species blooms between May and August on dry slopes and flats.

Blue-eyed Grass, Sisyrinchium bellum, is not really a grass at all, but it does have long, narrow leaves that look like grassblades. It also grows in meadow habitats. Blooming between March and May, the flowers are a composition of three petals and three sepals fused at the base. They can vary greatly in color, and probably by age. This one was pale enough that in bright sunlight I could not get a detailed image. So, I shadowed the flower in order to get the “pinstripes” to show.

Coast Paintbrush (“Indian Paintbrush”), Castilleja affinis, was also blooming. Its flowering period is generally March to May, and it occurs in drier habitats up to 3, 500 feet elevation. Paintbrushes are in the figwort family Scrophulariaceae.

I am familiar with globemallows here in southern Arizona, where they can sometimes be viewed as “weeds,” but I was blown away by the Bush Mallow, Malacothamnus fasciculatus. This perennial can grow to be a fifteen foot tall shrub! It blooms from April to July and like its relatives can occupy disturbed habitats as well as dry, pristine native niches up to 2, 500 feet.

Different flowers are to be found in the more moist, shady, wooded sections of Charmlee. The most conspicuous flower we came across there was the Canyon Sunflower, Venegasia carpesioides. The large and profuse blossoms can’t be missed. They have a long blooming period, too, from February to September.

Wedge-leaf Horkelia, Horkelia cuneata, is in the rose family, though I never would have guessed that. It is characteristic of the ecotone where the woodland meets the drier, more exposed parts of the coastal sage scrub habitat; it blooms between April and September.

Last but not least, Leafy California Buckwheat, Eriogonum fasciculatum foliolosum, was especially prominent near the park entrance and restroom facilities. It may bloom anytime between May and November. It is a favorite with some bees, including honeybees that can create a good honey from the nectar they harvest from these flowers.

There are certainly more wildflowers to be found in Charmlee and in the surrounding mountains. A good website for identifying most of them is Wildflowers and Other Plants of Southern California by Michael L. Charters. It does help to know at least what family the plant is in, however, as there is no color-coded search option for this comprehensive website.

Charmlee Wilderness Park

Charmlee Wilderness Park should probably be re-named “Charming” because it will become a favorite for anyone who visits there. Located at 2577 Encinal Canyon Road in the Santa Monica Mountains above Malibu, California, the woods, fields, and scenic views are sure to delight all hikers.

I had the pleasure to visit this city park (yes, a city park!) on May 19 with my new friends Kim Moore and Emile Fiesler. Both are first-rate naturalists intimately familiar with the flora and fauna of the area. There were plenty of plants and animals to keep me entranced, despite an unusually cool and wet spring this year.

One of the first animals to greet us was a Spotted Towhee. Normally, these birds are busy literally scratching out a living in the leaf litter under shrubs and trees. What a treat to be serenaded. We did see other birds, including the California Towhee, a much more drab cousin to the Spotted Towhee.

Wildflowers were in abundance, especially Bush Monkeyflower, Mimulus aurantiacus. It was the dominant shrub along wooded edges and ridgelines throughout the park. Mimulus of other varieties and colors were also to be found throughout the many parks I visited.

Another wildflower that caught my eye was this Mexican Pink, Silene laciniata. Plants in that genus are also known by the name “catchfly” because their sticky foliage often entangles insects. Apparently this particular species is common on the grassy slopes in coastal scrub habitat.

The East Meadow Trail at Charmlee is a must see if you like scenic views like this:

Hard to beat an ocean overlook on a reasonably clear day.

We hiked up the ridge to the Reservoir, now empty but on this day with a rock art peace symbol decorating its floor, and encountered two hilltopping butterflies. One was likely a Funereal Duskywing, Erynnis funeralis. The other was a magnificent male specimen of the Anise Swallowtail, Papilio zelicaon.

Coming down off the East Meadow Trail takes you through the Oak Groves on your way back to the parking area. The woodland offers pleasant relief after walking the hot, dry, open meadows. The flora and fauna are substantially different, too (stay tuned for an upcoming post on wildflowers of Charmlee).

As we pulled our car out of the parking space, we happened to notice a Calilfornia Whiptail lizard, Aspidoscelis tigris stejnegeri, break cover at the edge of the parking lot. The car idled while we debated whether to bother trying to get pictures of this regal reptile. Ultimately, we grabbed our cameras, got out of the vehicle, and approached the lizard ever so slowly. I fully expected the animal to bolt for the next county if I even blinked, but to my amazement it was incredibly tolerant, even allowing close-ups. As Kim put it, that was the “icing on the dessert of the day.”

Charmlee is open 8 AM to sunset, every day. There is a $4.00 parking fee. The modest nature center, not open when we were there, is normally open Saturdays and Sundays, 8 AM to 5 PM.

Aquarium of the Pacific

One of the many places I visited in southern California last month was the Aquarium of the Pacific in Long Beach. I was accompanied by Kim Moore who is a volunteer at this impressive facility. The aquarium is only thirteen years old (as of this June 20, 2011), and they just opened a new exhibit, “Arctic & Antarctic: Our Polar Regions in Peril.”

Located in the Long Beach Shoreline Rainbow Harbor Marina, the aquarium is flanked by restaurants and tour boats, with the Lions Lighthouse for Sight just around the corner (left of the above image). Kim and I took one of the harbor tours to break up the visit to the aquarium.

The first thing you encounter upon entering the aquarium is a life-size model of a female blue whale and her calf (hidden in this image), suspended from the ceiling. The adult fiberglass facsimile is “only” eighty-eight feet long, which it turns out is about average for the current population of this species. He name is “Edie,” and her male calf is “Edison.” The accuracy of these models is impressive, and one gets to truly appreciate the streamlined bodies of these leviathans.

Beyond the whale is a two-story window on a tank called the “Blue Cavern,” in the Great Hall of the Pacific. This tall exhibit is an excellent introduction to the kelp forest habitats common along the southern California coast. In this case, the inspiration was Blue Cavern Point along the northeast edge of Santa Catalina Island. Among the denizens of the exhibit are some impressive California moray eels, Gymnothorax mordax.

Adjacent to the Blue Cavern is the Amber Forest and other “galleries” depicting the marine life of southern California and the Baja peninsula. One small aquarium features a captivating colony of Garden Eels (Heteroconger sp.).

The indoor portion is just one facet of the whole complex. The aquarium also boasts outdoor exhibits that include shark and ray touch tanks where visitors can gently stroke harmless cartilaginous fishes like Bamboo Sharks and Bat Rays. Visible from both above the water and below are Sea Otters and California Sea Lions.

Yet another outdoor exhibit is the Lorikeet Forest, a 3,200 square foot aviary where visitors can feed these stunning birds. Five of the 32 subspecies of the Rainbow Lorikeet are on exhibit.

Native to Australia, New Zealand, and islands in the South Pacific, lories are under pressure from the black market pet trade and from farmers who view the birds as pests in fruit orchards.

Back indoors, the Tropical Pacific Gallery features fish and invertebrates from faraway places. A Northern Pacific Gallery holds animals (including birds like puffins and auklets) from the cold waters of British Columbia and Japan.

It is impossible to communicate in one blog entry all of the exhibits and entertainment opportunities afforded by the Aquarium of the Pacific. It is not a cheap attraction (admission is $24.95 for adults, $21.95 for seniors age 62 and over, and $12.95 for children 3-11), but well worth the price. You should plan on spending the whole day watching the birds, mammals, invertebrates and fish. Don’t be surprised if some of them watch you in return.
