Abstract

Species distribution models (SDMs) are often used to predict areas of suitable habitat for a species across a geographic extent, or to predict range changes due to climate change. These models rely on presence-only data for individuals distributed across a landscape, together with environmental conditions at the points at which individuals occur, in order to predict suitable habitats outside of the observed area. ​​MaxEnt has been commonly used to model the distribution of species when presence-only data is available, as opposed to scenarios where we also have true absence data. MaxEnt is being used in this study since only presence-only data are available. Here, a habitat suitability model of the Gaviota tarplant in western portions of Santa Barbara and San Luis Obispo counties is carried out.
