A crucial step in assessing biodiversity is listing the species that occur in an area. This activity has been shaped by the expertise of the faculty who have studied the campus, so that accounts of plants, birds, mammals, reptiles, and amphibians began in the 1980s (if there were earlier accounts, they have been lost). A number of important groups have no species lists, because they have not been surveyed on campus, or the surveys have never been published. Chief among these are the insects.
