Objective:

Develop a predictive marsh and tree island model quantifying the relationships between hydrologic parameters and the plant, soil and ecosystem components. In addition, the processes that create and maintain marsh heterogeneity and healthy tree islands will be documented. Hydrologic parameters are important, but poorly quantified, and include water depth, hydroperiod, water current velocity and timing of inundation. The overall objective is to provide the data needed to properly restore orcreate wetlands lost or highly modified by anthropogenic activities.

Approach:

Sets of five flume channels, each 10 x 300 m, will be constructed and used to test and quantify hydrologic treatments and tree island head construction design on plant and soil responses. The significant advantages flumes provide includes mesocosm size, highly controlled flume hydrology, the ability to test one variable at a time, and easily change treatments in a flume.

Expected Results:

Data which will: 1) be instrumental in the management, creation, and restoration of altered freshwater ecosystems; 2) address the hydrologic conditions required for a productive, healthy ecosystem with the proper attributes; and 3) provide the ability to maintain a mosaic of plant communities.
