Spring 2016 at Tejon Ranch is off to an exciting start! Lots of great work by our partners continues to demonstrate not only how important the Ranch is for protecting California’s biodiversity but also that it is an important place to better understand how our biodiversity originated. For example, you may remember that Dr. Jim Parham from California State University Fullerton posted a blog on his work with legless lizards in the genus Anniella back in August http://tejonconservancy.blogspot.com/2015/08/surveying-for-legless-lizards-on-tejon.html
Jim and his colleague Dr. Ted Papenfuss from the Berkeley Museum of Vertebrate Zoology have been studying legless lizards to better understand how the different species are distributed across California and related to each other in order to better understand the factors that drove the evolution of these species. Last year we found a juvenile legless lizard under a coverboard (actually a piece of cardboard on the ground), but juveniles can’t be positively identified without looking at their DNA. This year we went back to the same spot and found another adult legless lizard that has been positively identified as (drumroll please…) the Bakersfield legless lizard (Anniella grinnelli)! We also found a Bakersfield legless lizard along the Caliente Creek drainage at the edge of the northern part of Tejon Ranch, and another juvenile legless lizard at the Panofsky property also along Caliente Creek http://tejonconservancy.blogspot.com/2015/08/the-conservancy-receives-its-first_31.html

As explained by Jim in his blog, the Bakersfield legless lizard was only known to occur in two locations north and northwest of Tejon Ranch.

Another animal we found under the legless lizard coverboards was a long-nosed snake (Rhinocheilus leconte), a first for me. The gorgeous long-nosed snake is the only member of its genus, which is endemic to North America (found nowhere else in the world but North America). The long-nosed snake burrows through the sand like the legless lizard and may prey on legless lizards.

In other news from the spring, Nick Jensen continues to make significant new plant finds at Tejon Ranch. Nick added a new native plant from the morning glory family, spreading alkaliweed (Cressa truxillensis), to the Ranch list. However the really cool find in the same area was the San Joaquin Valley endemic Lost Hills crownscale (Atriplex coronata var. vallicola), which is a California Native Plant Society List 1B.2 plant (plant considered rare, threatened, or endangered in California and elsewhere).
And just to give you a taste of what is starting on the Antelope Valley side of the Ranch. A few photos of the wildflower bloom from this past week.

As you can see, Tejon Ranch continues to slowly reveal her hidden gems, and our knowledge grows with each of those revelations. We hope that you will join us in experiencing, exploring, and enjoying, as well as protecting, enhancing and restoring Tejon Ranch. Check out our website for upcoming activities!
