Healthy Wetlands: Valuing Both the Wet and the Dry
Jenkins, Kim; Panizzon, Debra
Teaching Science, v55 n1 p15-20 Mar 2009
February 2nd of each year is World Wetlands Day. It commemorates the signing of the Ramsar Convention in Iran in 1971 and the crucial role wetlands play in terms of ecological health. Not only do they provide essential habitats for many aquatic species of organisms but they are used by many terrestrial animals as temporary havens for food, or sites for reproduction. At a broader level, wetlands act as a buffer system for the surrounding landscape as they filter water thereby removing pollutants and excess nutrients. Healthy functioning of wetlands requires an important cycling between periods of inundation and drying in order to enhance their biological productivity and sustainability. While it is easy to observe and understand the impact of water during the wet, it is more difficult to fully appreciate the dry period. For many, a dry wetland is a lifeless and uninspiring place to visit. In this article we set out to change this view using an exciting investigation that will help students to appreciate the complex relationships that exist between the "wet" and the "dry".
