Invasive species are all over the state. In fact, the Minnesota Department of Natural Resources (DNR) has tracked more than 90 invasive species in Minnesota. In the map below, we’ve plotted some 180,000 reports of terrestrial and aquatic data collected by administrative bodies and volunteers. While not comprehensive, it gives a glimpse into how many non-native species have infiltrated the state.
The DNR is a great resource for raw data sets, from aerial photography to deer harvest numbers that go back a decade. Many of these datasets can be found in the Data Deli site, one of the most complete and usable data catalogs from any Minnesota government body. (You can also visit the DNR website to find out more about preventing the spread of invasive terrestrial and aquatic species.)
