About the Research

About the Research:

This research seeks to determine the impacts of microgeographic features and changing seasonal climate variables on the phenology of local herpetological species including terrestrial amphibians and reptiles in San Francisco North Bay protected areas which are deemed critical to protect for conservation purposes.

This research also creates and implements a long-term herpetofauna survey protocol using plywood coverboards while supporting the development of methods to apply citizen science monitoring efforts by volunteer biological monitors using a natural history mobile application (iNaturalist). These two project sites provide substantial opportunity to establish a baseline herpetofaunal phenology data set while simultaneously incorporating existing and developing programs to support longer-term monitoring efforts. Herpetofauna data has been collected since February 2014 and will continue to be collected to establish baseline data. Citizen science efforts have been incorporated into the iNaturalist Herpetofauna Project which includes 1,549 observations including a new distribution record for Black Salamander (Aneides flavipunctatus).

A series of large wildfires swept through northern California in October 2017, burning over 245,000 acres. The Tubbs Fire, which grew to become the most destructive wildfire in the history of California, burned large swaths of protected lands in the Mayacamas Mountains including one of the research sites (Pepperwood Preserve) and elsewhere. Investigation on the effects of wildfire and other environmental variables on the amphibian and reptile communities of these areas continue.

Burned Cover board

All coverboards burned in the forest plots at least partially. Half of coverboards burned in the canopy edge plots. Grassland cover boards were only scorched.

Alligator Lizard and its burned shedded skin.

Turtle Pond, Pepperwood Preserve. Mayacamas Mountains.

Turtle Pond, Pepperwood Preserve in Mayacamas Mountains burned everywhere but not the pond edge unlike the other pond site within the preserve. Future stats will determine if the lack of fire around the Turtle Pond edge provided a refuge for herps.

Distributing 108 – 1/2-inch thick 2’X4′ plywood coverboards at two different sites within Fairfield Osborn Preserve on Sonoma Mountain is not a job for wimps.

Realizing the wheel chart is useless on the steep and narrow trails, the coverboards are hauled up on our back, on our head, or however possible.

Just a friendly Jerusalem Cricket under an ancient coverboard at Double Ponds, Pepperwood Preserve. Not only are they not true crickets, they are not native to Jerusalem. These nocturnal insects feed primarily on dead organic matter but can also eat other insects.

Finally some cold rain and wind to break up this terrible drought. Not everyone was lucky enough to remember their snow goggles. Feb. 2, 2014.
