Brown Bag Lunch Lecture – January 17, 2019 – The Changing Wildlife and Environment of Joshua Tree National Park and the Mojave Desert

Thursday, January 17, 2019

Joseph Grinnell and his colleagues at the Museum of Vertebrate Zoology, University of California, Berkeley, documented the fauna of Joshua Tree National Park and the Mojave National Preserve through site exploration primarily during the late 1930s to the early 1950s. Since 2016, the Department of Birds and Mammals at the San Diego Natural History Museum has been resurveying these same sites, using the historic surveys as a standard for gauging more recent changes. In Joshua Tree, the main theme of change is the decrease of many species associated with chaparral and pinyon/juniper woodland, paralleling the decrease in these habitats wrought by drought and fire, but a few species have recently colonized Joshua Tree.  Join Dr. Lori Hargrove for this very informative lecture and see which species of birds and mammals are moving in and which have left the Morongo Basin.


Bio:  Dr. Hargrove first joined the San Diego Natural History Museum as a volunteer in 1995, where she became fascinated with birds and their habitat relationships. She went on to receive her PhD in Biology at UC Riverside, where she won numerous research awards. A focus of her study has been on elevational shifts of bird species and the mechanisms involved, including response to fire and climate change. She is now leading a variety of ecological research projects for the museum, including the NSF-funded Grinnell Resurvey Project.
