Aquatic Invasive Species - Dane County

Location:

Aquatic invasive species (AIS) records are assigned statuses of "verified", "observed", or "no longer observed" based on AIS Status Guidance. In general, "verified" populations are established and have been verified by a taxonomic expert. Populations with the "observed" status have not been verified by a taxonomic expert or do not have established populations. Populations with the "no longer observed" status include populations where a reproducing population did not establish. Our inventories are not necessarily exhaustive so it is important to report occurrences. To report new discoveries visit: https://dnr.wisconsin.gov/topic/Invasives/report.html. See the Aquatic Invasive Species Guidance for information on how statuses are assigned. Personally identifiable information on data collection forms may be provided to requesters to the extent required by Wisconsin's Open Records Law [ss. 19.31-19.39, Wis. Stats.].

* Observed – This is a record that has been observed in the field, but a specimen has not been verified by a taxonomic expert or an established population has not been found within the waterbody. Only dead AIS or few individuals of one age class have been observed, not an established breeding population. This will include dead individuals observed outside their growing season that will need to be revisited during target times to verify. This also includes historic monitoring data that has not been verified by a taxonomic expert.
