Emergent Marshes Flashcards
Emerging marshes are generally ________ deep and contain vegetation ________ that ________.
Emerging marshes are generally 6” to 3’ deep and contain vegetation rooted in soil that emerges above the water surface.
List 4 examples of emergent plants.
Emergent plants include cattail, bulrush, spikerush, and sedges.
Describe the value of emergent marshes for resident wading birds.
These marshes are valuable as nesting and brood rearing habitat for resident wading birds.
Describe the value of emergent marshes for migratory shorebirds, and waterfowl.
They provide feeding, resting, and roosting habitat for migratory shorebirds and waterfowl.
Describe the management of emergent marshes as it relates to moist-soil areas.
Emergent marshes are often managed in rotation with moist-soil areas.
Maximum use of emergent marshes takes place when plant cover reaches ________%, leaving ________% open water.
This is called a ________.
Maximum use of emergent marshes takes place when plant cover reaches 50%, leaving 50% open water.
This is called a hemimarsh.
March Succession Stages
________ —> ________ —> ________
As marsh succession occurs, a marsh will move from open marsh to hemimarsh to predominately emergent cover.
When should emergent marshes be manipulated?
Emergent marsh should be manipulated when invading woody plant stems are 2-3 inches in diameter.
Disturbance is best accomplished by ________ and ________.
This will set succession back to the ________
After disturbance, describe the wetland managment decision suggested by the authors?
Disturbance is best accomplished by bushhogging and heavy disking.
This will set succession back to the grass stage.
This area can then be managed for moist-soil while another area is allowed to become emergent marsh.
Describe a water level management action that facilitates the use of emergent marshes by migrating shorebirds and teal.
What habitat is provided/created as a consequence of this action?
Water levels of emergent marshes can be drawn down in late summer and early fall to provide mudflats and shallow water for migrating shorebirds and teal.
