# Entering Meta-Data

Before entering data, it is first necessary to add and select the citation that is the source of the data. It is also necessary for each data point to be associated with a Site, Treatment, and Species. Cultivar information is also required when available, but it is only relevant for domesticated species. Fields with an asterisk (\*) are required.
