The Holiday Farm Fire entered the Andrews Forest on September 12. Headquarters facilities were spared, but the fire and fire control lines impacted permanent vegetation plots that have been studied for 50 years, plus study plots for soil moisture, hydrology, plant phenology, and forest microclimate. Researchers are working quickly to set up monitoring and studies that will help us learn from the fire, and we have decades of pre-fire data to use as the foundation for comparisons.

In an era where climate change may generate hotter and drier conditions, tree health is a central concern of ecologists and forest managers. So how might a parasitic plant, like dwarf mistletoe, interact with the climatic conditions scientists project? A long-term data set and new study may provide the answer.

A new research project at the Andrews Forest aims to shed light on how changes in temperature and precipitation affect patterns of biodiversity. The Forests of Oregon Elevation Gradient (FOREG) is a network of large sample plots, established in 2019, within the HJ Andrews Experimental Forest.

Researchers at the Andrews Forest are studying how dwarf mistletoe may be affecting forest stands across the Pacific Northwest. The work requires getting up to where the mistletoe grows: high in the canopy of the trees.

A new study at the Andrews Forest aims to document migration routes, locations, and migratory connectivity of Hermit Warbler populations.
