Wetland Ecology and The “Mud Walk!”

Over 70% of Earth is covered by Water!!!

Fresh Water Use

“Drip Water Irrigation” most efficient, but used on less than 1% of crops worldwide.(Expensive)

Water is Finite

Technically, what are wetlands? Must fit one or more of following qualities: hydrophytes (plants that live in water) Water table stands at or near the land surface the substrate is predominantly undrained hydric soil the substrate is saturated with water or covered with water sometime during the growing season. “The Most Biologically Diverse Of All Ecosystems”

Water Levels: Water levels drop during the summer and by late fall these levels are at the lowest. Many dry up. *Vernal (ephemeral) Pools Aquatic invertebrates become dormant. Plants have root system that is very extensive allowing them to survive. Re-flooding occurs, plants and animals come back to life

Water Levels: Re-flooding is very good for a wetland to increase productivity of the area.

High MARSH Mineral Soils SWAMP Water Level Organic Soils FEN BOG Low High Nutrient Availability

Benefits of Wetlands?

Prevent Floods & Droughts

Purifies water

50 % of MN have been drained (50% of wetlands worldwide since 1993)

How to drain a wetland???

Succession: A predictable and orderly change in the composition or structure of a biological community

Succession of Wetlands: New Ponds: Pioneer Species is Algae Submergent Stage: a few plants are growing under water near the shore Emergent Stage: More plants growing and sediment causes the pond to become more shallow as basin begins to fill Prairie Biome Forested Biome Dense Marsh Stage: Basin becomes very shallow and emergents, sedges as well as grasses cover the wetland Bog: Growth of trees and shrubs that grow on a carpet of moss. Majority of water is gone due to sedimentation. Wet Prairie Stage : Standing water gone. Area may become invaded by native trees and shrubs such as willow and cotton woods.

Wetland Succession

Blaine High School 1979

Wetland Succession in Action

Blaine High School Wetland Wetland Type 2: Wet Meadow “It appears the Wet Meadow was historically the predominant community type occurring at this site. However, suppression of fire and alteration to the hydrologic regime has resulted in a significant influx of Cattail Marsh and Willow Swamp. Willow Swamp community type is a common feature of Wet Meadows; however, historic periodic fires would set this plant succession stage back. The predominance of reed canary grass and stinging nettle in the southeastern portion of the wetland typically indicates that historic ditching may either partially or effectively drain this area.”

Bog Walk Objectives To experience first-hand and in a physical way a strange new environment To learn to work together and to solve problems involved in data collection To recognize the element of danger and adventure To share with others the laughter, fear, enjoyment, frustration and hard work involved in the experience. To have a better understanding of lake succession. To be able to identify and classify various organisms collected in the marsh To take part in a scientific study that will contribute to our understanding and documentation of our surrounding environment.

Learning Targets: 1. I can describe two features that dictate wetland composition. 2. I can experience firsthand and in a physical way characteristics of a local wetland ecosystem. 3. I can describe the stages of ecological succession specifically applied to wetland variation. 4. I can identify three factors that influence lake succession. 5. I can discuss the historical significance of wetlands to Minnesota and identify ways in which these wetlands have changed.

What to bring Duffle bag with clean clothes and towel. Wear old clothes. Long pants, long sleeve shirt, socks and shoes.

What to do?? * Bring bag with clean clothes, towel, etc. to loading dock. *Class Bog walk. (NO THROWING MUD) *Hose off at loading dock, grab your bag. *Walk behind school to *ENTER DOOR #3: Soccer locker rooms *Bring dirty clothes home, or put in dumpster. *Class grade based on cleanliness of locker room. *Stay in Phy. Ed area until bell rings.
