More Mesa Symposium Online

Many supporters who were unable to attend the 2014 More Mesa Symposium have inquired about obtaining a video of the presentations. And many who did attend have been interested to review what they saw and heard.

These are just two of the many reasons we are extremely pleased to announce that the entire 2014 Symposium is now available on our web site. The six separate videos include, a brief introduction to the Symposium, four presentations from experts on More Mesa:

  • Ecology – Wayne Ferren
  • Raptors – John Storrer
  • History – Valerie Olson
  • Development – Dan Gira

… and the Panel Discussion that ended the morning session.

These talks may be found in the “Events” section of the More Mesa Preservation Coalition web site at /symposium-2014-videos/.

We hope that all of you who care about More Mesa will find these important educational resources filled with useful and interesting information. From them we can take enormous pride in the desire of our community to preserve this unique and cherished part of our South Coast world.

Of late, there has been a flurry of articles about the caves located in the cliffs on the west side of More Mesa.  These stories have been precipitated by a recent and unfortunate incident of a young man being severely injured by a falling rock in one of these caves.  While we cannot offer solutions to prevent this from ever occurring again, we can offer some fact-based scientific information about why it is extremely dangerous and unwise to traverse down to the beach or visit, and especially linger, in any of these caves.

Geology Facts:  The cliffs of More Mesa are distinctly different on the east and west sides.  The east side cliffs consist of Monterey Shale, a clay formation that is 6-18 million years old.  This section of the cliff erodes slowly and its 100 foot drop to the beach below is along a sloping grade.

However, the west side of the cliff face is of the Santa Barbara Formation, a younger sedimentary formation of marine sand that is only 700,000 years old. (The big blobby tar seeps oozing onto the More Mesa beach are from the Santa Barbara formation.)

This younger material erodes very quickly.  Indeed, sea cliff retreat in the Santa Barbara Formation has been demonstrated to be about 10 inches a year, the highest rate observed along this portion of the South Coast. What this all means is that the western cliff is steep, unstable and unpredictable.  Further …

• The western cliff should never be used to access the beach
• Visitors to More Mesa beach should never use areas close to the western cliffs
• The caves should never be occupied.

One further cautionary note … when it starts raining again, do not use the trail closest to the cliff face after a rain.  It may disappear as you are admiring the view.  Please be careful!

California is in a state of “Extreme Drought”, with 2014 being the driest year since 1895, 119 years ago! But, in spite of this disastrous condition, one can still observe some native wildflowers in bloom on More Mesa. For example, Deerweed, which normally blooms from March to October, has been in flower constantly for more than a year. Heavily populating the east-west coastal trail, it most likely prospers in this severe drought because it is a plant that is able to survive on the moisture left behind from the many fogs that visit us in spring and summer.

Deerweed, also known as California Broom, is not only resourceful, but has a fascinating adaptation. This dainty, native Chaparral plant has a clever way of attracting pollinators to the correct flowers. Beginning yellow, the flowers turn red after pollination.  Bees cannot see the color red, so it keeps them from wasting time on flowers that have already been visited.

In addition to the non-native honeybee, Deerweed flowers are pollinated by native bees in the Bombus, Hoplitus, Osmia, Agapostemon, Anthophora, Habropoda, and Anthidium  genera. [1] Deerweed is pollinated by butterflies (nectar source), and also serves as a host plant to many species of butterfly larvae. Once the flowers have been pollinated, the resulting seeds provide food for birds and rodents. Lastly, per its name, deer feed on the plant, where they are found together.

Reptiles and Amphibians: In the past we have highlighted many of the biological resources found on More Mesa: birds, plants, mammals and, in last month’s update, our colorful insects, the butterflies. So it seems timely that the recent finding of a very long Gopher Snake shed should prompt this month’s discussion of the reptiles and amphibians of More Mesa.

More Mesa is thought to support at least 22 species of reptiles and amphibians. Reptiles occur throughout all the habitats and include common species such as the Western Fence Lizard, Western King Snake, Gopher Snake and Slender Salamander, as well as sensitive species such as the Southwestern Pond Turtle. (Gopher Snakes as long as 8 feet have been observed on More Mesa.) On the other hand, amphibian species are concentrated within wetland and riparian areas and include the Western Toad, Arboreal Salamander and Pacific Tree Frog.

Gopher Snakes as long as 8 feet have been seen on More Mesa.

Summer Butterflies: If you have not already discovered it, we encourage you to check out one of our web site’s many slide shows of photographs of Butterflies seen on More Mesa. Furthermore, there is a downloadable pdf Guide.  And, happily, at this time of year you can see more and more of these local beauties in the open. For example, when you visit More Mesa you are likely to see Anise Swallowtails: butterflies that lay their eggs on our ubiquitous fennel. And a second species regularly observed, flying low and sitting on bare ground, all over More Mesa, is the Common Buckeye.

AmazonSmile: On another note, a financial one at that, we are pleased to announce the More Mesa Preservation Coalition has been registered to receive 0.5% of the purchase price of all eligible products selected by Amazon customers.  This program conceived by Amazon, and known as AmazonSmile, can be accessed by entering Amazon at a slightly different web address. This web address can also be found at the lower right side of our Monthly News (this) page, below the Sitemap button. Shopping with AmazonSmile is identical to shopping with Amazon in the conventional way, with a very few products being exempted from the program.

We urge all of you who love More Mesa and want to help, to bookmark this new page and use it instead of the Amazon URL you are currently using. Thanks so much!
