National Fish Habitat Action Plan (NFHAP) 2010 HCI Scores and Human Disturbance Data (linked to NHDPLUSV1) for North Carolina:
ESRI Service Definition
Dataset Identification:
Resource Abstract:
This service definition contains landscape factors representing human disturbances summarized to local and network catchments
of river reaches for the state of North Carolina. This dataset is the result of clipping the feature class 'NFHAP 2010 HCI
Scores and Human Disturbance Data for the Conterminous United States linked to NHDPLUSV1.gdb' to the state boundary of North
Carolina. Landscape factors include land uses, population density, roads, dams, mines, and point-source pollution sites. The
source datasets that were compiled and attributed to catchments were identified as being: (1) meaningful for assessing fish
habitat; (2) consistent across the entire study area in the way that they were assembled; (3) representative of conditions
in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local
catchment units. In this data set, these variables are linked to the catchments of the National Hydrography Dataset Plus Version
1 (NHDPlusV1) using the COMID identifier. They can also be linked to the reaches of the NHDPlusV1 using the COMID identifier.
Catchment attributes are available for both local catchments (defined as the land area draining directly to a reach; attributes
begin with "L_" prefix) and network catchments (defined by all upstream contributing catchments to the reach's outlet,
including the reach's own local catchment; attributes begin with "N_" prefix). This service definition also includes
habitat condition scores created based on responsiveness of biological metrics to anthropogenic landscape disturbances throughout
ecoregions. Separate scores were created by considering disturbances within local catchments, network catchments, and a cumulative
score that accounted for the most limiting disturbance operating on a given biological metric in either local or network catchments.
This assessment only scored reaches representing streams and rivers (see the process section for more details). <br /> <br

purpose:
These data were collected for multiple purposes. First, they were gathered in support of conducting a condition assessment
of fluvial waterbodies throughout the United States in support of the National Fish Habitat Action Plan (NFHAP). Second, these
data were intended to be made available to NFHAP Partnerships as well as other users interested in acquiring consistently-organized
information available characterizing river systems over larger regions. This work was supported by local, state, and federal
partners of NFHAP, including the U.S. Fish and Wildlife Service and the U.S. Geological Survey. Because the condition assessment
was conducted over such a large geographic region, we adopted a landscape approach for assessment which assumed that anthropogenic
disturbances as well as natural characteristics in the watersheds affect a given unit of habitat which in turn would affect
fishes. It was necessary to use a landscape approach because landscape data are available for every location in of the United
States whereas local measures of habitat or biological indicators of habitat condition are only available at a very small
percentage of locations around the country.
