Tesla Road, 8/9

It was a great night for an evening drive along Tesla Road in eastern Livermore. The objective was to look for San Joaquin Kit Foxes, but we failed to find them. Kit Foxes are both nocturnal and extremely difficult to see. We did, however, manage to see several other species of Bay Area animals.

As the evening light faded, we first spotted a Tarantula as it was crossing the road. As we were attempting to get him out of harms way in a timely manner, it managed to crawl into the wheel on our car. After several minutes of banging a stick on the tire, it finally decided to come out and wandered off to safety.

As we drove along, we also saw a Gopher Snake cross the road. When threatened, Gopher Snakes tend to sharpen their heads so that they resemble something like triangles, something we had noticed before while driving along Mines Road which is also in Livermore. This one was no exception.

Driving a little further east on Tesla Road yielded two Western Rattlesnakes. We managed to snag a picture of the second one, its eyes gleaming in the headlights. Note the defensive position.

The fact that we saw three snakes as well as a tarantula crossing the road combined with a decent level of traffic shows how easily animals can become roadkill. Drivers must be careful always.

On the way back, we saw a Barn Owl fly along the road for a bit and then veer off. And then a Desert Cottontail by the side of the road. No Kit Foxes but plenty of wildlife.

Coyote Creek Lagoon, 6/28

A quick walk in Coyote Creek Lagoon last Sunday yielded little overall diversity of species, however we had great sightings of a Forster’s Tern dipping and flying in breeding plumage.

A big flock of American Avocets, Marbled Godwits, and Long-billed Curlews also took off in beautiful shapes and patterns. Other interesting species seen were Snowy Egrets (also in breeding plumage) and Common Ravens.

Field trip to Lime Ridge, Walnut Creek

This trip marked two special things. One was Father’s Day. The other was the start of our search for the elusive Coast Horned Lizard. We had read about some sightings in Lime Ridge Open Space and decided to head there. Our walk in Lime Ridge was through some fairly open grassy slopes, interspersed with some chaparral, rock outcrops and a few trees. We were keenly eyeing every sandy patch on and off trail and getting our hopes up at the sight of each ant colony we encountered. As usually happens with wildlife outings, we ended up seeing several other interesting species.

One avian highlight was the Rufous-crowned Sparrow. We had several great sightings and heard 2 different vocalizations. Before this we had only gotten fleeting glimpses or distant looks. Other nice fillers were a pair of Ash-throated Flycatchers and four Bewick’s Wrens in one tree.

It turned out to be a good day for insects. We saw 6 species of butterflies – Common Buckeye, Anise Swallowtail, Variable Checkerspot, Acmon Blue, Mylitta Crescent and Cabbage White. My second “officially” recorded species of odonate (dragonfly) – Variegated Meadowhawk. To round out the variety of animal life we also saw a mother Black-tailed Deer and her young one. And a fat, flattened-out Western Fence Lizard really got our hearts racing.

We ended up empty-handed or rather empty-eyed. We could not locate the Horned Lizard. But the search will continue. You can see some great photographs of the Horned Lizard here on wildherps.com. Lime Ridge is located at the foot of the northern slopes of Mount Diablo. Much more information about our local wildlife and wild areas is found on sfbaywildlife.info.

Users Advisory Group, 6/18 – East Alameda County Conservation Strategy

I attended about the first 50 minutes or so today, June 18th, of the Users Advisory Group meeting for the EACCS. To get some background, please go to their website here.  Their website has a lot of good information. I would like to praise them for the amazing job they have done with utilizing their website to distribute and publicize information about the strategy. Posted on the website are past meeting minutes, future meeting agendas, detailed drafts of the strategy, and much more. I encourage you to check it out.

I feel from my perspective, that of a wildlife enthusiast with no particular agency loyalty or technical background, I hold a unique perspective on these meetings and I can draw out information which would be pertinent to the general public. If you want more objective background of what was discussed or more details to substantiate my opinions below, again please look at their website for meeting notes or other documentation.

For the amount of time I was there, there were two points other people made that stood out to me in particular. The first was the issue of “keeping common species common.” One individual (sorry I did not note who) made the point that the strategy was concentrating too much time on focus species such as the Red-legged Frog or the California Tiger Salamander, and neglected to address the common species. The individual asserted that common species are the true marker of an ecosystem’s health. A member of the steering commmittee said there were regulatory reasons for addressing the focus species, among other reasons. There simply aren’t enough resources available to members of the strategy to save every specie in every habitat. I agree on both counts. Common species are intrinsically linked to the focus species, as all wildlife is linked in various types of food chains or mutualistic partnerships which should not go unnoticed. But the issue does remain that generating political capital to even implement strategies such as this is extremely difficult, and we should use our resources wisely.

The second point that struck me as interesting was the idea of working at the regional level as well as the habitat level. From my limited understanding of the strategy, I can see it targeting various species and various habitats – identifying the ones that are in need of conservation based on a number of factors. However, another individual pointed out that regional conservation was important as well. By this, he meant preserving landscapes and areas. Preserving the shape and nature of the East Alameda County as a composition of a variety of habitats and species is a different perspective than targeting specific habitats and specific species, but it is another valid perspective. Habitats and specifies do not function by themselves, and we as people who enjoy the beauty of nature do not generally see isolated habitats and species. What we see are landscapes and regions composed of a multitude of things. Therefore we should consider their conservation as well.

Another point I thought of while the meeting was going on was the issue of the “general public.” The strategy, as far as I have seen, uses factors such as “focal species needs” or “habitat goals” to produce conservation guidance and mitigation guidance for the strategy, but one variable I did not initially see was what I call the “appreciation” variable. I believe making natural places accessible and well-known to the general public should be a factor in this strategy. This is one of the goals of sfbaywildlife.info. I will do more research about the strategy before I hold additional judgment.

All in all, I am very impressed so far by the collaborative, modern, and open effort to create a conservation strategy for East Alameda County.
