National Fish Habitat Partnership (NFHP) 2010 HCI Scores and Human Disturbance Data for Hawaii Linked to NFHP Catchments (developed using the 1:24,000 scale National Hydrography Dataset) VERSION 2.0

This shapefile contains sub-indices comprised of various anthropogenic land use/covers respresentative of the risk of potential habitat degradation to streams within the state of Hawaii. This file is an updated version of 'nfhap_hci_hawaii.shp' and incorporates the suggestion from the Hawaii Fish Habitat Partnership of removing trails and paths from the road network to help better represent amounts of disturbance in remote areas such as the Na Pali coast. Subindices are summarized for local and network catchments specific to perennial stream reaches throughout the state. The local and network catchments were developed using a modified version of the 1:24,000 scale National Hydrography Dataset (NHD) as a baselayer. Sub-indices include urban impacts, agricultural land use, former plantations, density of ditches, point source pollution, stream fragmentation, and 303D listed streams . The indices compiled and attributed to NHD catchments were developed using landscape variables identified as being: (1) meaningful for assessing potential risks to fish habitat; (2) consistent across the entire study area (i.e., five main Hawaiian islands) in the way that they were assembled; (3) representative of conditions since 2000, and (4) of sufficient spatial resolution that they could be used to discriminate among conditions in local catchments. This shapefile also includes composite scores combining information from all sub-indices that estimate total risk for each NHD stream reach in Hawaii.
