East Bay Mountain Lion Ecology

Wednesday, November 18, 2020 — 7:30 pm

Speaker: James “Doc” Hale

View Recording

Mountain lions occasionally cross the suburban-wildland interface into our neighborhoods, where they are encountered by residents or their pets. Doc Hale has been studying their presence (or absence) in Contra Costa County for over 48 years and will present survey monitoring results, personal observations, ecology (including the lions’ indirect impact on our plant communities), and images of these shy carnivores captured on wildlife cameras.

James “Doc” M. Hale has been a professional vertebrate zoologist, certified wildlife biologist, ethnobiologist, and ecological consultant for 48 years. He has conducted field research throughout California (as well as other states), is an ecological consultant for various private and public organizations, conducts varied wildlife surveys, and has developed numerous environmental impact reports. He has broad knowledge of the cultural and natural history of California and leads interpretive field trips to cultural sites. His current projects involve analyzing mountain lion ecology in Contra Costa County; researching Native American archaeology; and recording the wildlife, plants, and archaeological sites at Brushy Peak Regional Preserve in Livermore.

Our CNPS East Bay speaker programs will be presented as online meetings until it is once again safe to gather in person. If you have questions, contact programs@ebcnps.org.
