COSEWIC Status: Endangered
COSSARO Status: Endangered
- An aquatic plant, it has a cluster of weak and stringy leaves that rise from two corms.
- Leaves usually measure 20 to 40 cm, but can extend to 90 cm.
- Leaves often float on water or sprawl across mud flats; the corms are not usually visible, but buried in the soil.
- Colour of the leaves varies from bright green to brownish-green.
Habits and Reproduction
- Reproduces through spores, which mature in late summer.
- Mixing of megaspores (female) from one plant with microspores (male) from another start new plants.
- Spores are usually dispersed by water currents, so tend to be close to the parent plants.
- Corm is anchored in sand and clay soil in shallow water along the shoreline.
- Changes in water levels and quality.
- Increase in water based recreational activities.
- Toxic spills and seepage from private and public facilities are also potential threats.
- Competition from other aquatic vegetation.
- Abundance of Zebra Mussels.
- If you live near water, your actions on your property can affect water quality. The Muskoka Watershed Council have excellent information available regarding sustainable waterfront living.
