Biologist, Jeff Alvarez, has been working with sympatric populations of California tiger salamanders and California red-legged frogs for nearly 20 years. These apparently disparate species have many similarities and differences, yet aquatic and upland management techniques that support one species appear to support the other. Since the range of red-legged frogs and tiger salamanders overlap over a large area in California, species' management can impact or benefit both species. Jeff will present a lecture that includes discussion about the benefits of grazing, silt and vegetation removal, ground squirrel management, as well as habitat associations, rate of sympatry, inter-annual variability in observed breeding, and more, time permitting.
