Prof. Wiersema's research focuses on international environmental law, with particular emphasis on international wildlife law, species and biodiversity conservation, and forest conservation. Her most recent work addresses debates about markets for endangered species and the REDD+ program under the international climate change regime. In addition, she writes about the structure of the international environmental legal system, having addressed the role of conferences of the parties in international law-making.
