Original Base maps were prepared by the Division of State
Lands in 1972 and 1973 using aerial photographs from the
U.S. Geological Survey (USGS EROS Data Center, NASA). These
base maps were used in 1978 and 1979 by the Oregon
Department of Fish and Wildlife in its mapping of estuarine
habitats as part of DLCD's estuary inventory project. ODFW
used aerial photography, published studies, and some onsite
investigation to prepare its maps of estuarine habitats.
Estuary and shoreland planning designations were compiled
from local plans in 1986-87 by DLCD. Neither the DSL base
nor ODFW study cover the Columbia River estuary. The base
map for this area is a 1"" = 1000' map prepared by the
Columbia River Estuary Data Development Project (CREDDP) in
1983. Habitat information for the Columbia River was
prepared by staff of the Columbia River Estuary Study Task
Force (CREST) in 1985. CREST compiled various CREDDP
studies, converted data to the ODFW habitat classification,
and prepared the habitat map provided here.
Comprehensive plan and habitat maps were digitized by the
Oregon Department of Energy in 1986 and 1987 using an
ARC/INFO Geographic Information System. Full scale maps
(usually at 1"" = 1000') were photographically reduced to
fit the format of the Plan Book document, and are produced
at varying scales.
Digitized maps were reviewed by DOE and DLCD staff to
identify inconsistencies and digitizing errors. The most
common inconsistency was disagreement between the ODFW
Habitat Map and the local plan maps in establishing the
location of the estuary shoreline. DLCD staff reviewed
aerial photographs. plan documents, and consulted with
local planners to resolve inconsistencies.

Description:
Abstract:
This coverage represents estuary habitats defined by Oregon
Fish and Wildlife. Polygons are coded with a nine digit
number that represents a hierarchical habitat structure.
Purpose:
Distinguishing between different habitats is important to
understanding the effects of different kinds of activities
and managing their impacts. Through the estuary
classification scheme discussed below it is possible to
identify unique environments that tend to control the
production and composition of the communities that utilize
them. It is possible to classify those environments by
using only a few different parameters.
Supplemental Information:
In 1979, the Oregon Department of Fish and Wildlife (ODFW)
published a series of maps and reports that classified the
various habitats in each of Oregon's major estuaries.
Completed soon after LCDC adopted Statewide Planning Goals
concerning coastal resources, ODFS's maps were intended to
be used by local governments as they developed their
estuary management plans. ODFW's classification system is
based on a United States Fish and Wildlife Service (USFWS)
habitat classification system (Cowardin et al., 1977) that
was designed to address a large variety of parameters
affecting aquatic habitats. Since the USFWS system was
designed to be applicable to all types of aquatic habitats
nationwide, it includes parameters that were unnecessary
for describing Oregon's estuarine habitats. Consequently,
ODFW modified the system to utilize only those parameters
that have the greatest influence on Oregon's estuarine
habitats. Classification of habitats and their communities
is useful in evaluating the potential environmental impacts
of site-specific proposals on an estuary. The ODFW
estuarine habitat classification system incorporates tidal
regime, landform, and sediment or vegetation type. These
have been identified as primary factors controlling the
composition of biological communities. Although a
classification system that relies heavily on benthic
substrates does not address all types of estuarine
communities, sessile plants and invertebrates are directly
influenced by bottom types, and adaptations for burrowing,
attachment, and feeding are closely linked to specific
types of substrate. The distribution of fishes and other
mobile species is dependent at least in part on the
availability of feeding and spawning areas and protective
cover along the estuary bottom. Sediment distribution
indicates both the source of the parent material and the
velocity and direction of tidal or river forces
transporting the sediment. Therefore, habitat distribution
is also influenced by the balance of these forces. For
example, river-dominated systems have a high percentage of
low-salinity subtidal habitats based on terrestrial
sediments. Estuaries with a greater marine influence
typically have large amounts of intertidal habitat and a
mixture of both marine and riverine sediments.
Consequently, they offer greater diversity of habitat types
and, in turn, probably support a greater diversity of
species. Finally, it is important to distinguish between
sediment type and habitat type, since similar classes of
substrate alone do not represent similar environments. For
example, communities that inhabit subtidal sand bottoms in
the lower and upper estuary often differ significantly due
to variations in salinity, flow velocity, or other factors
independent of substrate type. Thus the location of a
substrate type within the entire estuarine system will
affect the species composition utilizing that habitat.
