FIELD OPERATIONS MANUAL FOR ASSESSING THE HYDROLOGIC PERMANENCE AND ECOLOGICAL CONDITION OF HEADWATER STREAMS
FRITZ, K. M., B. R. JOHNSON, AND DAVID M. WALTERS. FIELD OPERATIONS MANUAL FOR ASSESSING THE HYDROLOGIC PERMANENCE AND ECOLOGICAL CONDITION OF HEADWATER STREAMS. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-06/126 (NTIS PB2007-100972), 2006.
The goal of this research is to develop methods and indicators that are useful for evaluating the condition of aquatic communities, for assessing the restoration of aquatic communities in response to mitigation and best management practices, and for determining the exposure of aquatic communities to different classes of stressors (i.e., pesticides, sedimentation, habitat alteration).
The purpose of this manual is to document procedures that were developed and used by the Ecological Exposure Research Division, NERL, ORD, for the assessment of the physical and biological characteristics of headwater streams; and to provide a catalog of procedures to other groups with an interest in headwater stream assessment. This document provides methods specifically designed for assessing the hydrologic permanence and ecological condition of headwater streams.
