Proctor is currently involved in studying the effects of patch burning on vegetation and livestock production in the Southern Great Plains. Some interests include the role of fire and herbivores in maintaining diversity in rangelands, implementing sensor technology in monitoring rangeland environments, impacts of feral hogs on native communities, and brush encroachment in rangelands.
Before joining the Noble Research Institute, Proctor earned his master's degree in biology while studying the vegetation and communities of an inland salt marsh in southeastern Kansas. He then spent five years working for the Oklahoma Biological Survey conducting floral inventories and mapping plant communities and wetlands on military installations throughout the United States.
While employed for a private consulting firm, Proctor worked on projects associated with pipeline and seismic exploration activities impacting American burying beetles and bald eagles in southeastern Oklahoma. He also worked on several projects in southeastern Texas involving environmental monitoring and vegetation studies in Big Thicket National Preserve, Trinity River National Wildlife Refuge and Sam Houston National Forest.
