National Fish Habitat Partnership (NFHP) 2015 Human Disturbance Data for Hawaii

This CSV file contains landscape factors representing anthropogenic disturbances to stream habitats summarized within local and network stream catchments as well as the downstream main channel catchment perennial and intermittent stream reaches of the five main islands of Hawai'i. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) broadly 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. Variables summarized at the catchment scale include measures of anthropogenic land uses, golf courses, population density, roads, ditches, pipelines, dams, mines, point-source pollution sites, and locations of former plantation lands. In this dataset variable summaries are linked to the Hawaii Fish Habitat Partnership (HFHP) stream layer (Tingley et al. in prep) which is a modified version of the 1:24,000 National Hydrography Dataset that consists of 11,436 intermittent and perennial stream reaches across the five largest Hawaiian Islands (Hawaii, Maui, Molokai, Oahu, Kauai). Catchment attributes are available for both local catchments (defined as the land area draining directly to a reach; attributes begin with L_ prefix) and upstream network catchments (defined by all upstream contributing catchments to the reachs outlet, including the reachs own local catchment; attributes begin with N_ prefix). Downstream main channel variables for reaches are labeled using a D_ prefix. This table can be joined to local drainage catchments (found in https://doi.org/10.5066/F7PC30HG) using the field MergeID.
