We put together a story map to bring attention to Flowering Rush as well as our survey and eradication project. Flowering Rush was first detected in the South Saskatchewan River by the Alberta Invasives Species Council. In 2018, we started to survey the spread starting in the Leader area.
Flowering Rush can:
- Grow prolifically in irrigation ditches reducing water flow and increasing maintenance costs
- Colonize previously open-water areas of lakes and slow-moving streams, impacting recreational activities by intertwining boat propellers and reducing angling opportunities.
- Support habitat for the great pond snail which hosts the parasite that causes swimmer’s itch.
- Adversely impact native fish species, specifically those adapted to open water habitats such as bull trout and cutthroat trout, by forming dense stands and limiting spawning areas.
