The objectives of this research project are to: (1) develop, implement and disseminate tools for accomplishing tessellation stratified sampling in a GIS context; (2) develop, determine and evaluate landscape indicators suitable for spatial and temporal analyses of Environmental Monitoring and Assessment Program (EMAP) and similar data being examined in subprojects 1 and 2; (3) explore statistical aspects of the definition of regional species richness, or more generally, taxonomic richness; (4) evaluate protocols for economically determining site level aggregate indicators, including habitat features, macroinvertebrate assemblages, and chemical determinations; and (5) investigate the limitations of using current data, which is widely available but probably ill-suited for regional statistical analyses.

Progress Summary:

The major focus during the past year has been to continue to build better links between watershed parameters and reaches. Tools for accomplishing tessellation stratified sampling in ARCVIEW have been developed and are in the final quality assurance testing stages. We continued to compile data for the Modeling of Mid-Atlantic Highlands Streams Assessment study area, but now will focus on building the base data for the Western Pilot study area. We also continued to develop basic network modeling tools in geographic information system (GIS).

We collaborated with other EPA Science To Achieve Results (STAR) Program researchers, especially those at Colorado State University. Estimation of regional taxa richness continued with the Southern California Coastal Water Research Project. In addition, doctoral student Erin Poston attended the 23rd Annual ESRI International User Conference, San Diego, CA, July 7-11, 2003.

Future Activities:

We will develop predictors for stream size and flow status (perennial and nonperennial) to overcome limitations of the materials currently used as a frame for stream sampling National Hydrography Data Set (NHD). Initial work would utilize the EMAP-WEST survey of stream traces identified as non-perennial in NHD. The initial stream flow investigations will begin with the Mid-Atlantic Highlands area.

We will continue to develop landscape metrics based on direct measures of stream discharge to develop a regression relationship between watershed conditions and Index of Biotic Integrity.

Erin Poston, a Ph.D. student, will develop a hierarchical approach to model landscape and fine-scale habitat predictors of macroinvertebrate diversity.
