UPRLIMET Project Update

In response to forest practices regulations in the U.S. Pacific Northwest (PNW), a team of researchers from the USDA Forest Service PNW Research Station and Oregon State University developed the UPstream Regional LiDAR Model of Extent of Trout (UPRLIMET) to help identify the upper limit points above which all streams are considered fishless. Since the last partner meeting in October 2023, the UPRLIMET development team has focused on (a) gathering fish-presence data from various sources, (b) refining environmental models, and (c) implementing predictive methods tailored for the autocorrelation structure of stream networks.
