Douglas Thomas Bolger

Professor of Environmental Studies
Adjunct Professor of Biological Sciences

As an ecologist and conservation biologist, I am interested in how human land use affects animal and plant populations. My research projects have examined the impact of residential development in the coastal sage scrub ecosystem of Southern California and of agricultural intensification in landscapes surrounding national parks in Africa.
