If you publish these data or use them for analyses in publication, EPA requires a standard statement for work it has supported: 'Although the data described in this article have been funded wholly or in part by the U.S. Environmental Protection Agency through its EMAP Surface Waters Program, it has not been subjected to Agency review, and therefore does not necessarily reflect the view of the Agency and no official endorsement of the conclusions should be inferred.' 2. INVESTIGATOR INFORMATION 2.1 Principal Investigator Spencer Peterson U.S. Environmental Protection Agency NHEERL Western Ecology Division 200 S.W. 35th Street Corvallis, OR 97333 2.2 Investigation Participant- Sample Collection State of Oregon State of Washington U.S. Environmental Protection Agency, Region 10 3. DATA SET ABSTRACT 3.1 Abstract of the Data Set This data set contains a list of metrics derived from the species composition within the stream at the time of sampling. The metrics summarize the species relative abundance information by collapsing it into a series of metrics representing trophic guilds, habitat preferences, tolerance capacities and measures of biodiversity. 3.2 Keywords for the Data Set Benthos assemblage, benthos community, benthic species identification 4. OBJECTIVES AND INTRODUCTION 4.1 Program Objectives The Environmental Monitoring and Assessment Program (EMAP) was designed to periodically estimate the status and trends of the Nation's ecological resources on a regional basis. EMAP provides a strategy to identify and bound the extent, magnitude and location of environmental degradation and improvement on a regional scale based on a probability-based statistical survey design. 4.2 Data Set Objective This data set is part of a demonstration project to evaluate approaches to monitoring streams in EMAP. The data set contains the calculated metrics of multi-habitat sampling to summarize benthos assemblage data. 4.3 Data Set Background Discussion The benthos assemblage metrics summarize the species relative abundance information by collapsing it into a series of metrics representing trophic guilds, habitat preferences, tolerance capacities and measures of biodiversity. 4.4 Summary of Data Set Parameters The benthos assemblage metrics include summarized counts and percentages of the sample for certain families of taxa, trophic function groups, and pollution tolerant and intolerant taxa. In addition, for each sample the Modified Hilsenhoff Biotic Index and the Shannon-Weaver diversity index are reported. IDAS is the Invertebrate Data Analysis System written by Tom Cuffney of USGS, and was used to create the metrics file based upon the bentcnt_oridas file. 5. DATA ACQUISITION AND PROCESSING METHODS 5.1 Data Acquisition 5.1.1 Sampling Objective To obtain a sample of the benthos assemblage within a stream during a during a sampling window from July through September. 5.1.2 Sample Collection Methods Summary The assemblage was sampled using modified kicknet with 595 micron mesh distributed in multiple habitats throughout the stream. 5.1.3 Sampling Start Date July 6, 1999 5.1.4 Sampling End Date September 7, 2000 5.1.5 Platform NA 5.1.6 Sampling Gear Modified kicknet with 595 micron mesh, buckets, 500 um sieve, forceps, funnel, sample jars, ethanol, pocket knife, rubber gloves, sieve-bottomed bucket. 5.1.7 Manufacturer of Instruments Wildco #425-C50 - modified kicknet. 5.1.8 Key Variables NA 5.1.9 Sampling Method Calibration NA 5.1.10 Sample Collection Quality Control See Lazorchak, et al. 1998. 5.1.11 Sample Collection Method Reference Lazorchak, J.M., Klemm, D.J., and Peck D.V.
