• Root Systems: Wetland plants often have specialized root systems to cope with low-oxygen environments. Some may have visible aerial roots or pneumatophores.
• Flower Structure: Pay attention to the arrangement and shape of flowers, as well as their color and blooming season.
• Growth Habit: Note whether the plant is emergent (growing above the water surface), floating, or submerged.
• Habitat: Consider the specific type of wetland and its characteristics, as this can help narrow down potential species.

For accurate wetland plant identification, it’s always best to use a field guide specific to Illinois or consult with local botanists and naturalists.

Ecological Significance of Wetland Flora

The plants found in Illinois wetlands play crucial roles in maintaining healthy ecosystems:

• Habitat Creation: Wetland plants provide shelter, nesting sites, and food for a wide variety of wildlife, including birds, mammals, amphibians, and insects.
