Join Don Thomas for a four mile walk to see the southernmost population of western leatherwood (Dirca occidentalis). We will also see some early emerging woodland plants in flower. There will be some moderate but slow-paced hill climbing, with a stop for lunch.

As the most southern population of this endemic species, it may be the most impacted by climate change. We will try to monitor the health and viability of the population and, if possible, get a better population count.

Bring lunch, snacks and liquid. Heavy rain cancels.

We will meet at the parking lot near the intersection of Stevens Canyon Rd. and Mt. Eden Road. For more information, please contact Don Thomas at This email address is being protected from spambots. You need JavaScript enabled to view it. or (408) 828-4044.
