Abstract:
We seek to expand a recently developed wetland classification and functional assessment protocol, created
in Pennsylvania, to regions north and south within the Appalachian mountains. We want to determine
if similar wetland types occur along a broad latitudinal gradient, and if wetland structure and function
are similar.
Approach:
We will build (and improve) upon a large data set developed in Pennsylvania. We will utilize standard assessment protocols designed to measure 36 structural variables for input into wetland functional assessment models. We will revisit 20 extant study sites in Pennsylvania to update their information. We will develop approximately 20 new reference sites each in New York and Virginia in an attempt to test the applicability of these models along a broad latitudinal gradient. We will instrument all study sites with continuous water level recorders so as to develop comprehensive hydrologic data for site assessment. These data will be used in the assessment models as well as a check on the classification of each wetland.
Expected Results:
We expect to show whether models developed over many years in one region can be successfully (and rapidly) applied in two other adjacent regions. If this is true, then the time needed for the development of wetland classification and assessment tools can be greatly decreased, saving both time and money, and allowing for better assessment and protection of wetland resources. These results will address EPA's need for improved ecosystem classification schemes and reference condition identification.
