DATA SET ABSTRACT 3.1 Abstract of the Data Set The benthos community within a stream is an integral component of stream biological integrity. This data set contains a list of species and counts of numbers of individuals of each species collected at each stream sampled. 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 results of multi-habitat sample of the benthos assemblage taken during spring low-flow. 4.3 Data Set Background Discussion The benthos assemblage within a stream is an integral component of stream biological integrity and represents a publicly visible reflection of stream quality. This data set contains a list of benthic species and counts within the stream at the time of sampling. 4.4 Summary of Data Set Parameters The benthic assemblage parameters include individual 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. 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 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.
