Spatial distribution models are often used to identify priority habitat by correlating the geographies of species distributions with environmental conditions.  One primary assumption of species distribution models is that species are at ‘equilibrium’ with their environments.  That is, the species exists in all environments that are suitable for its population growth and does not exist in unsuitable environments.  This seminar will explore whether both invasive and native plants in the US follow an equilibrium assumption and the implications of these potential biases for informing conservation and management.
