HNA Summary Report
Information Needs

This first Habitat Needs Assessment for the UMRS reveals clear needs for additional information that is necessary to characterize river habitats. As an example, more detailed information is needed to improve the rule-based approach to predicting successional change of UMRS plant communities. Such a model should incorporate site characteristics (geomorphic unit type, hydrologic regime), and information on plant community response to disturbances (flood, wind, fire). Better information on existing floodplain plant communities is also needed.

A list of information needs is presented below
to help improve future UMRS Habitat Needs Assessments.

1. System-Wide High Resolution Topographic Data.

2. System-Wide Bathymetric Data

3. Numerical Hydraulic Models of all Navigation Pools

4. Substrate Type Characterization

5. Habitat Spatial Structure Metrics

6. Floodplain Inundation Models.

7. Floodplain Geomorphic Classification and Survey

8. Surveys of Existing Floodplain Plant Communities

9. Characterization of the Existing and Pre-Impoundment Hydrologic Regime

10. Confirmation/Validation of Species:
       Habitat Models Using Stratified Random Sampling Data

11. Development of Refined Life History Information

12. Development of Refined Species:Habitat Models

13. Analysis of Seasonal Habitat Availability
