Widespread

Widespread aquatic animals are species that have established themselves in the region, leading to the use of multiple management practices. These practices primarily include containing a species if it is in a low enough abundance and/or developing local management strategies to suppress their impacts.

​Factsheets for each of these species are coming soon.
