Attack of the Azolla!

Attack of the Azolla!

Azolla covers habitable locations within the nature preserve at Madrona Marsh as an invasive species. A thin layer of Azolla, a free-floating freshwater fern, covers the marsh with alternating hues that range from fluorescent green to dark burgundy. Ferns are some of the first plants to originate before gymnosperms and angiosperms evolved.
