Vegetation Ecology

John Taft’s research focuses on vegetation ecology of oak woodland and grassland habitats with an emphasis on factors that influence structure, composition, and diversity.  Projects span a range of topics from plant-soil interactions, edge effects in small and isolated prairie remnants, development and testing of habitat-quality indices useful in habitat restoration and natural areas surveys, interactions between overstory and ground layer vegetation and fire effects in fire-dependent oak woodland ecosystems, and ecology of montane grassland ecosystems.
