Trask River Watershed Study: Fine benthic material sampling, 2008-2016

These data are a portion of the larger Trask River Watershed Study which was conducted in the East Fork of the South Fork Trask River of the Coast Range of western Oregon. Basin-wide surveys of fine benthic particulates were conducted over the course of this study. In-stream deposition of fine sediments (These data are a portion of the larger Trask River Watershed Study. The general objectives of the Trask River Watershed Study were to investigate the effects of forest harvest on the physical, chemical and biological characteristics of small headwater streams, and the extent to which alterations in stream conditions caused by harvest along headwater channels influence the physical, chemical and biological characteristics of downstream fish-bearing streams. The primary role of this sampling was to characterize the abundance and composition of fine benthic particulate material. The organic fraction can be an important source of food for benthic detritivores, while the inorganic portion can have adverse affects on stream biota. Samples were collected from both surface and shallow subsurface (2-5 centimeters depth) habitats.For more information about these data and this study, see Johnson et al. (2022).
