Dr. Börk's research concerns environmental law, natural resources law and administrative law, focusing on the interplay of science and law, with the goal of producing scholarship that will be useful to practicing lawyers, judges, and policy makers in the environmental field. Professor Börk previously taught Environmental Law in the Environmental Studies Program at the University of Kansas and taught Testmasters LSAT courses for seven years. Professor Börk's publications run the gamut from the definitive text on the history and application of California Fish and Game Code Section 5937 to a hatchery and genetic management plan for a new conservation hatchery. Professor Börk is currently examining legal and ethical issues in ecological restoration, with a particular focus on the management of guest species, those invasive species that managers invite in and make comfortable. He is also working on a review of distinct population segment listing decisions under the Endangered Species Act, particularly with regard to steelhead populations in California.
