The Most Wonderful Treasure….


As the end of the Lockdown approaches, I have been musing about how to “wrap up” our Treasure Hunts. How does one describe the entirety of the treasures of More Mesa … those few that I wrote about, and the hundreds of others that exist in this magical and remarkable place. Indeed, the most wonderful treasure on the whole South Coast is More Mesa itself!
What were our Treasure Hunts about? Over the past months, we discovered many of the individual treasures of More Mesa. We did this in fun looks at its trees, plants, birds, Insects, arachnids, reptiles, animals and even some man-made stuff. We reported on treasures that are native to our area, and even some that were imported here for various reasons and have since become difficult-to-control nightmares.

c28b4297-ff21-4723-afda-e230ef49b0f4All of these treasures make their homes in one or more of the habitats of More Mesa. So … what’s the big deal? The big deal is that 80% of More Mesa has been identified as Environmentally Sensitive Habitat or ESH. ESH is the designation for a special place where plant and animal life, or their habitats, are rare or extremely valuable because of their special role in an ecosystem; one which could be easily disturbed or degraded … by us!
Now comes a really big AHA … More Mesa is extraordinary in that it contains five different, distinct and unique habitat types … more than any other open space on the South Coast! It begins with a distinct vegetation community created by differences in topography, soil types, sun exposure and moisture. Then each plant community, in its turn, determines the types of wildlife that will be present. Thus, three important factors, physical features, vegetation and wildlife, create a unique habitat. With that background in mind, we can explore where all the treasures we talked about for the past 15 months make their homes within their special habitats.

Trees Crave Lots of Water: We talked about four species of trees; Willows, Cottonwoods, Sycamores and Oaks. All these trees need water, and we typically find the first three somewhere very near water. Their habitat, Riparian Woodlands can be found on More Mesa near Atascadero Creek and its adjacent flood plains as well as canyons and ravines.

Oaks have their own special habitat which is called, appropriately enough, Oak Woodland. For me, having been a climber in my youth, this beautiful habitat is hauntingly reminiscent of the forests in the foothills of the Sierras.

More Mesa’s Plants Live in all Habitats: Our plant Treasure Hunts had us looking for plants that live in soil, wet soil and water as well. We searched for Miner’s Lettuce, Elderberries, Datura and various water plants. We even devoted a whole issue to dreaded invasive plants; species brought to the Goleta Valley as cash crops, good feed for cattle or just by accident!

The Miner’s Lettuce we looked at in Spring likes the shade of an Oak Woodland, while Elderberry prefers a little water in its life and does well in Riparian Woodlands. Datura seemed to thrive in almost all habitats.

fcc93dad-0353-470d-a740-48b995fc7537Our issue on water plants looked at plants that populate Wetlands … like Atascadero Creek and its adjacent marshes, canyon and ravine bottoms, meadows and open water pools.

However, the most remarkable Wetland we have on More Mesa is a Vernal Pool on the southeast corner. These very special and fast disappearing wetlands, are seasonal pools that fill with winter rainwater, and then dry out gradually thru the Spring and early Summer. Vernal Pools support a variety of rare water plants. Our own Vernal Pool was studied extensively the last time it filled, in Spring of 2019, and was subsequently identified as the most prolific Vernal Pool in all of the Goleta Valley. To learn more about Vernal Pools, and why the ones that remain are so very important, read about these unusual wetlands on our website.

Remember how bees can see in the ultraviolet? This coastal path is also likely to give the visitor a good look at a Western Fence Lizard and perhaps a lone, impressive, and completely harmless, large Gopher Snake. A look skyward over the ocean might also include a Western Gull hunting for a sea food dinner.

The coastal walk, includes all of the fourth habitat on More Mesa, Coastal Bluff Scrub, a habitat that, when we are fortunate enough to get enough rain, offers us a spectacular late winter show. The star of this show is the California Brittle Bush, with its cast of hundreds of thousands of yellow blossoms decorating the top of the cliff and many feet below as well.

Mostly It’s Grass: The last habitat on More Mesa is also the largest … Grasslands … a habitat that can be found throughout level mesa areas and on some canyon slopes.

In the mid 1800s, when More Mesa was occupied by grazing cattle, grass was really important. And while More Mesa is no longer home to even a single cow, grasslands continue to play a critical ecosystem role. First, Grasslands are home to myriad species of small birds who eat seeds. And of vital importance, seeds and grasses provide food for small mammal populations … think Voles, Mice, Gophers, Rabbits and Squirrels. And you might remember the progression we talked about in earlier issues, wherein grass seeds provide food for small mammals and then small mammals serve as food for sensitive raptors as well as larger mammals. In other words, Grasslands are the cafeteria for almost all birds and many mammals.However, while small birds also make their homes in the Grasslands, raptors only use it as a cafeteria and generally live in other habitats … habitats with trees.


For example, and of major importance, in seasons with adequate rainfall, More Mesa can become home for up to 4 nesting pairs of our famous signature bird, the White-tailed Kite. Remarkably, in this year of extremely low rainfall, we have two adult pairs that are, even as I write this, feeding 6 hungry offspring!

We also looked at other birds in our Treasure Hunts, among them Great Blue Herons, Owls and Roadrunners. All of these, as well as the Kites, find food in the Grasslands of More Mesa, with the Roadrunner living there as well. Even the Peregrine Falcon, preferring birds for breakfast and dinner finds sustenance from the smaller birds that make their homes in the grasslands of More Mesa.
What about those larger mammals? We often have sightings of Bobcats, medium sized cats that feed on smaller mammals found on More Mesa. And, on another remarkable front, two Mountain Lions were spotted on the northwest part of More Mesa this year!

Big and tiny … our Treasure Hunts also looked at the Butterflies and Spiders found all over More Mesa’s Grasslands. And finally, the “man made stuff”, was a look at an important chapter in our country’s history and a fun departure from our usual hunts.

More Mesa is Part of a Bigger Picture: Habitats aside, it is important to remember that the canyons and ravines of More Mesa are linked to Atascadero Creek and larger regional ecosystems; systems providing wildlife migration corridors that reach all the way from the foothills to the shore.

Walking on More Mesa is a voyage back more than two centuries. Saving it preserves an important look at what was, all that we have lost and what we still can save. It is the last great place in Santa Barbara.


It has been an honor and a privilege to explore the treasures of More Mesa with you during this difficult and tumultuous time. Thank you for letting me come into your homes to share the wonder of this beautiful, magical piece of our history.
Look for more traditional news updates about More Mesa in the upcoming months and, most of all, thank you for reading the Treasure Hunts and thank you for caring about More Mesa … Valerie

Earthquake on More Mesa?

On the very first day of last month, at 8:42 in the morning, a magnitude 2.7, earthquake was reported for the More Mesa area. This event was incorrectly labeled in the press as the “Goleta Earthquake”. However in fact, the longitude and latitude of the quake epicenter placed it near a residence in Hope Ranch, about 1/3 mile due east of the edge of More Mesa (See aerial photo below.)

This low magnitude quake was not an unusual occurrence because our area, like most of California, is riddled with earthquake faults … and tremors are very frequent. For example, there have been 97 events of magnitude 1.5 or greater in Santa Barbara during the last year. The geologic map below shows various faults in the immediate area of More Mesa, with either black or red lines depending on the geologic deposits involved. Prominent among all the small faults shown, and at the north-eastern section of More Mesa, is the intersection of two larger faults, the More Ranch Fault and the Lavigia Fault.

To learn more about the geology of More Mesa, go to our 2014 Symposium videos and click on any of the titles. All Symposium videos will then appear on Vimeo. Geology is discussed in the talk titled “Ecology of More Mesa.”

We are indebted to the U.S. Geological Survey for providing the new and updated map geologic map of the Santa Barbara area, a map formulated with a major contribution from our own Dr. Edward Keller of UCSB.


December 2004

It has been a busy year for the More Mesa Preservation Coalition. Many hundreds of hours have been spent in proactive activities to preserve the beauty, habitats and wildlife of this lovely open space … March restoration event, providing information on native plants and invasive species, and observing and monitoring native fauna.

In addition, more than a thousand hours have been expended to the challenge of insuring appropriate development on the edges of More Mesa. We believe we are being heard, and are making on an impact on planning agencies in County government. This phase of our work is often intensely frustrating, but it is worth every moment when you consider our mission … to preserve More Mesa forever.

Celebrate the season in a most glorious way … visit More Mesa. You will find renewed conviction and energy. This precious place is worth the fight!! In addition, check January News for an overview of MMPC plans for the year 2005. Our warmest holiday wishes to all of you.



The More Mesa Preservation Coalition (MMPC) is a group of concerned citizens committed to preserving More Mesa in perpetuity. Members include professionals, neighbors, conservationists, activists, scientists, planning specialists, students, hikers, equestrians, cyclists and beach goers. More than 1000 people have already signed on to be made aware of what is happening to More Mesa and have given offers of help. We believe that we represent a broad coalition of members of the whole Goleta Valley community.

The MMPC tracks events and development proposals that may affect the ecological, recreational and scenic values of More Mesa, and takes appropriate action to protect these essential values of the Mesa. Our long-term goal is to work cooperatively with the site’s private owner, government agencies and the community, in order to purchase the remaining 265 acres for long term preservation. The entirety of More Mesa and its beach could then be managed as a nature park, protecting both the habitat and recreational values of this incredible site.
