Background Information:

Wetlands are one of Earth's most valuable ecosystems that provide a variety of functions in nature. These functions may be biological, physical or chemical. Wetlands are a great source for wildlife habitat. One-third of all endangered species make their home in wetland areas. Through groundwater recharge, small amounts of water trickle into the ground providing drinking water and irrigation. Wetlands act as "mother nature's kidneys" by increasing water quality. They also help with flood control by acting as nature's giant sponges.

Wetlands are valuable in other ways to humans by providing us with many special benefits. There are consumptive benefits, such as hunting and fishing. These recreational activities can bring in people from all over. Wetlands provide non-consumptive, aesthetic benefits as well. These include bird-watching and trail observation. Many people enjoy the beautiful scenery that the wetlands offer.

Wetlands are multiple-value systems, providing value for many different reasons. The most valuable products are those with public amenities: flood control, wildlife habitat, groundwater recharge. Wetland development is often irreversible. Estimates of values depend on what an individual gets, individual biases and biases of society.

Extensions for advanced learners:

Give students opportunities to create crossword puzzles or word-finds with the terms and definitions learned throughout the unit.

Assign particular wetland areas to research and report on.

Research other ecosystems and compare/contrast to wetlands.
