Our society, and California in particular, has an urgent need for professionals with deep ecological insight who can manage systems to ensure the long-term sustainability of human and ecosystem health. The M.S. in Ecology and Sustainability is a thesis-based, 2 year degree program with two possible concentrations: (1) Ecological Conservation, and (2) Ecological Economics. Students study and conduct field and laboratory research in a variety of systems, including nearby habitats such as wetlands, grasslands, rivers, oak forests, and marine ecosystems, as well as in agricultural lands, urban areas, restored ecosystems, and social/economic systems.?
