Description
- Abstract: The Aquatic Inventories Project is designed to provide quantitative information on
habitat condition for streams throughout Oregon. This information is used to
provide basic information for biologists and land managers, to establish monitoring
programs, and to direct or focus habitat restoration efforts.
Development of an Aquatic Inventories Project began within the Oregon
Department of Fish and Wildlife (ODFW) in 1989 with sponsorship by the
Restoration and Enhancement Program. Drafting of stream survey methods and
implementation of field work began in 1990. The conceptual background for this
work came from the experience of project staff and from interactions with Oregon
State University, forest industry, and USFS PNW research scientists (Bisson et al.
1982, Grant 1986, Everest et al. 1987, Hankin and Reeves 1988, Moore and
Gregory 1989, and Gregory et al. 1991). Significant contributions and review of
these methods were provided by ODFW research staff, and from consultation with
ODFW and United States Forest Service (USFS) biologists working on similar
programs. Members of the Umpqua Basin Fisheries Restoration Initiative and the
Oregon Forest Industry Council have provided additional review and consultation.
This methodology was designed to be compatible with other stream habitat
inventories and classification systems (i.e., Rosgen 1985, Frissell et al. 1986, Cupp
1989, Ralph 1989, USFS Region 6 Level II Inventory 1992, and Hawkins et al.
1993). This compatibility is achieved by systematically identifying and quantifying
valley and stream geomorphic features. The resulting matrix of measurements and
spatial relationships can then be generalized into frequently occurring valley and
channel types or translated into the nomenclature of a particular system. For
example, information summarized at the reach level (valley width, channel type,
slope, terrace height and width, sinuosity, width, depth, substrate, eroding banks,
etc.) can be used to characterize the stream into one of the types described by
Rosgen (1985) or to match the parameters collected in other quantitative (USFS) or
historic (U.S. Bureau of Fisheries) surveys.
The process of conducting a stream survey involves collection of general
information from maps and other sources and the direct observation of stream
characteristics in the field. This information is both collected and analyzed based
on a hierarchical system of regions, basins, streams, reaches, and habitat units.
Supervisors are responsible for collecting the general information on regions and
basins and for directing the activities of the survey crews. Survey teams will collect
field data based on stream, reach and channel unit characteristics. Region and
basin data will primarily come from ODFW-EPA region and sub region
classifications, and from map analysis.
The following instructions and definitions provide the outline for these activities and
a description of the tasks involved in conducting ODFW’s stream habitat inventory.
Each field crew is comprised of two people with each member responsible for
specific tasks. The "Estimator" will focus on the identification of channel unit
characteristics. The "Numerator" will focus on the counts and relative distribution of
several unit attributes and will verify the length and width estimates for a subset of
units. The "Estimator" and "Numerator" share the responsibility for describing reach
characteristics, riparian conditions, identifying habitat unit types, and for quantifying
the amount of large woody debris. Crew members may switch responsibility for
estimator or numerator when they start a new stream. They will not, however,
switch estimator and numerator jobs on the same stream.
