The Invasive Species layer is created from the ANR Invasive Species database.

The IPIEDT is an Access Database file. The user responds to questions in a “yes/no/unknown” format or chooses from a list of states or conditions that best describe the situation. Each descriptive response corresponds to a numerical value which is then used to calculate species and area scores and generate ranked lists. A higher species or area score correlates to a higher priority for inventory. The workshop's resulting data tables are archived so that the results of the workshop are preserved if the master database receives changes based on new threats or areas. Each Invasive Plant Species and Area Prioritization Workshop will have an IPIEDT Access database and 2-3 stand-alone CSV outputs. Each table is offered as an open source CSV and the Access Database tool zipped and is also available for download.
