• Swamps

• Bogs

• Fens

Which is NOT a threat to wetlands?

• Conversion

• Degradation

• Conservation

• Invasive Species

A type of invasive species in wetlands, shrub which grows on riverbanks & consumes incredible amounts of water and depletes water sources for native plants.

• Saltcedar

• Water hyacinth

• Nutria

Sets standards for waste discharge and other sources of point-source pollution. Protects wetlands and the water quality of the Great Lakes (which makes up 84% of the freshwater in the US.)

• The Farm Bill

• Clean Water Act

• Migratory Bird Hunting and Conservation Stamp Act (Duck Stamp Act)

Which is NOT a wetland conservation method?

• Protection

• Restoration

• Management

• Deforestation

The study of properties and movement of water within wetland habitats. Effects the amount of groundwater recharge or surface storage and productivity of the habitat. Check all that it includes.

• Hydroperiod

• Hydrodynamics

• Oxygen cycle

• Water source and chemistry

Spongey tissue and channels within the leaves, stems and roots of plants allowing air to pass through providing oxygen for growth. Found in plants such as water lilies, rice, common or soft rush.

• Aerenchyma

• Cypress Trees

• Aerial Roots

• Floating Leaves

Are root structures found on cypress trees which protrude above the soil. While the function is officially unknown, they are thought to allow roots to access oxygen by sticking out of the water.

• Aerenchyma

• Cypress Trees

• Aerial Roots

• Floating Leaves

Are adaptations to allow aquatic plants to root in flooded areas but maintain leaves and flowers above water to achieve photosynthesis. Found in water lilies.
