For larger datasets, please email us a spreadsheet or database with as much information as you have gathered. We will use the fields that we need and retain those that we do not in a file in the event that they become necessary for interpreting some aspect of the data. We will sometimes concatenate information from one or more fields into a single field, or vise versa. More data is better, but at a minimum we need a species name, observation location, and observation date.
