Understanding dissolved oxygen concentrations in a discontinuously perennial stream within a managed forest

The concentration of oxygen dissolved in water affects aquatic organisms. Unrestrained logging and site preparation can depress (DO) concentrations adjacent streams by elevating temperatures (with removal riparian shade), impounding channels (reduced reaeration rates), introducing fresh, oxygen-depleting slash. One the first paired watershed studies investigating use streamside management zones, Alsea Watershed Study (AWS) coastal Oregon (1958–1973), highlighted potential to DO harvest units. This other spurred development Best Management Practices (BMPs) forest practice rules maintain, among things, favorable streams. A new study watersheds (2006–2015) found little signal effects on concentrations. It did find that a discontinuously perennial stream (where reaches go subsurface during low flows) experience naturally Forest managers avoid exacerbating conditions using simple BMPs, but are predisposed
