Objective:
Analyzing stream biological assemblage data at a national scale is extremely difficult and rarely attempted due to the problems of compiling the necessary database. Our goal is to assemble a national database for the conterminous 48 U.S. States of stream/river fish, macroinvertebrate and periphyton assemblages derived from regional scale synoptic surveys. Our objectives are to 1) use our national database to develop 10-30 biologically driven national "classes" of stream systems; 2) within each class, separate natural from anthropogenic effects on stream ecological condition; and 3) establish quantitative relationships between catchment and riparian condition and water body condition (structure and function).
Progress Summary:
Final national working fish and macroinvertebrate databases have been compiled from available Environmental Monitoring and Assessment Program (EMAP), Regional EMAP (REMAP), state agency and U.S. Geological Survey (USGS) National Water Quality Assessment Program (NAWQA) data. The working fish data set has 530 different species from 5,951 unique sampling sites. The working macroinvertebrate file has 715 taxa from 3,680 unique sampling sites. Multivariate analyses (cluster analysis and ordination) have been performed on both national datasets and more intensive data rich regional datasets. Numerous manuscripts on various phases of the analysis are in press or in review.
Future Activities:
Datasets have been finalized and most analyses are near completion. The primary focus of work in the next year will be to complete manuscripts for all the pieces of the project.
