ʻŌhiʻa lehua (Metrosideros polymorpha) is Hawaii’s most important native tree. It covers nearly one million acres and is deeply intertwined with Native Hawaiian cultural practices. However, Rapid ʻŌhiʻa Death (ROD) caused by the invasive fungal pathogens Ceratocystis lukuohia and Ceratocystis huliohia, has killed over one million ʻōhiʻa trees across 270,000 acres. ROD poses a significant threat to Hawaii's biodiversity and cultural heritage. Safeguarding ʻōhiʻa and halting ROD’s spread requires urgent and coordinated action. Through its ROD research programs, the Forest Service is taking up th...

The Adelgid Population Dynamics Tool: Developing a Spatially-Explicit Management Model

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 ...
