Directions -
Zebra mussel sighting locations are represented by yellow and red markers on this map. States where zebra mussels have been found in inland and adjacent waters are identified by an orange tint. Moving the cursor back and forth over the year indicators on the control bar allows you to view the spread of this invasive species backward and forward in time. Moving over the loop arrow will make the dynamic map continuously loop to show the geographic progression of zebra mussels over time. Looping may be paused by moving the cursor over a specific year tab. Moving the cursor over an orange colored State will display State names at the bottom of the map. |
