About Sharon

Tisher teaches environmental law and energy policy courses, as well as courses in the Honors College “great books” curriculum. Prior to joining the University of Maine in 1994, she was a trial partner in the Connecticut law firm of Day, Berry and Howard. She has served as chair of the boards of the Maine Organic Farmers and Gardeners Association (MOFGA) and the Natural Resources Council of Maine, and directed MOFGA’s Public Policy Committee for ten years, focusing on stricter regulation of genetically engineered crops and genetically modified organism (GMO) labeling, and pesticide notification and reduction policies. She served for seven years as a member of the Steering Committee of the Alliance for a Clean and Healthy Maine, advocating for stricter national and state regulation of chemicals in consumer products. She has served on the Governor’s Task Force to Promote Safer Chemicals in Consumer Products, on the Maine Commission to Study Biotechnology and Genetic Engineering, and on a variety of advisory committees to the Maine Board of Pesticides Control. She has given testimony in regulatory and legislative hearings related to Constitutional takings law, GMO regulation and labeling, pesticides regulation, and safer chemicals regulation. She is currently primarily involved in advocacy for sounder climate policy. In connection with a course on climate policy, she has developed a 40 page color-coded chronology tracking developments in climate science, international policy, and U.S. policy over the last century. She is a member of Al Gore’s Climate Reality Leadership Corps, and delivers the current iteration of Gore’s Nobel Prize-winning slide show, supplemented with her own materials, at venues throughout Maine.

Provides links to news and commentary for further research. Displays the connections and disconnections between science and policy, and offers readers the opportunity to develop their own understanding of the origins of those disconnections.

"Pesticides Quiz and Primer" Maine Organic Farmer & Gardener (2019).

Presents a list of questions, drawing from information and research found in peer-reviewed journals, advocacy group commissioned studies, and venerable science texts to educate Mainers who would endeavor to increase their knowledge of pesticides and their understanding of safe, alternative treatments and methods.

"Climate Policy 2015: Reports from the Congressional Trenches" Maine Policy Review 25, no. 1 (2016): 72-76.

"Everglades Restoration: A Constitutional Takings Analysis" (with Peter Mills). Florida State University Journal of Land Use Planning and Environmental Law 10, no. 1 (Fall 1994).

Details the restoration endeavors that the government will have to take to counter the ecological crisis in the Florida Everglades (including restoring the hydrology of the region to more closely approximate pre-flood control and pre-drainage groundwater levels, flooding and sheet flow dynamics, effecting the "unchanneling" of once meandering rivers, and transforming agricultural or residential lands to wetlands), and analyzes Florida common law and federal constitutional law to determine whether such restorative efforts are likely to be characterized as unconstitutional "takings" requiring compensation.
