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 John Stoddard U.S. Environmental Protection Agency NHEERL Western Ecology Division 200 S.W. 35th Street Corvallis, OR 97333 2.2 Investigation Participant- Sample Collection U.S. Environmental Protection Agency Office of Research and Development, Region 10 3. DATA SET ABSTRACT 3.1 Abstract of the Data Set The primary function of the stream habitat data set is to describe the physical habitat quality within the stream and near-shore riparian zone. This information is used to help establish the 'expectations' of the biological quality of the stream and to evaluate the extent to which human activity has disturbed habitat and thus impacted stream biota. 3.2 Keywords for the Data Set Habitat, cover, large woody debris, pools, riffles, residual pools, instream cover, riparian habitat, riparian zone 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 analysis of the instream and riparian habitat sampled during spring low flow. 4.3 Data Set Background Discussion Habitat in streams is analyzed for two purposes. First, to understand the physical habitat within which biota must exist so that we can understand the biological potential of the system and second, to evaluate the physical habitat quality of the stream for the purpose of determining the potential stresses to which the biota are exposed. 4.4 Summary of Data Set Parameters The physical habitat parameters include percentages and total counts of various in-channel and riparian features, such as substrate size, water flow types, fish cover, channel sinuosity, riparian vegetation types, canopy density, and proximity of human influence features. 5. DATA ACQUISITION AND PROCESSING METHODS 5.1 Data Acquisition 5.1.1 Sampling Objective To obtain a quantitative description of stream physical habitat during a sampling window from June through October. 5.1.2 Sample Collection Methods Summary Quantitative habitat information was collected at eleven transects along the sampling reach according to the protocols identified in Lazorchak et al. (1998). 5.1.3 Sampling Start Date June 30, 1997 5.1.4 Sampling End Date October 15, 1997 5.1.5 Platform NA 5.1.6 Sampling Gear Fisherman's vest, 50 m tape measure, clinometer, tripod, .5 inch diameter pvc pipe (2-3 m), canopy densiometer, compass, meter stick. 5.1.7 Manufacturer of Instruments NA 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.
