30 years of stream habitat monitoring data from Tongass National Forest, Alaska, USA, 1991-2020
This data publication includes 1991 to 2020 stream habitat monitoring data compiled from several projects on the Tongass National Forest, Alaska. Data from 862 habitat surveys were collected on 333 fish-bearing stream reaches (sites) in an area approximately 500 kilometers from north to south and 200 kilometers from east to west at their greatest points. Variables were collected by personnel taking empirical measurements of stream habitat characteristics, while other data were extracted or calculated from Geographic Information System (GIS) databases. Empirical field measurements include, but are not limited to, reach length, channel bed width, slope, various large woody debris measurements, undercut bank, riffle and pool measurements, and substrate measurements. Data extracted from GIS databases include data related to LTA, catchment size, roads, canopy cover, historic harvest, hydrological classification, and process group. Other data include time since last harvest, location coordinates, and HUC 12 watershed name.<br>These data were collected as part of several different stream habitat monitoring projects on the Tongass National Forest over a 30-year period from 1991 to 2020. We have compiled these data in order to analyze and understand how timber harvest practices, climate change, and other factors shape stream habitats.<br>For more information about this study and these data, see Moore et al. (in press).
