For our Winter 2021 meetings (Jan, Feb, March) we are discussing fire. The 2020 fire season will leave its mark on ecosystems of the western Cascade Mountains, inside and outside the boundaries of the HJ Andrews Experimental Forest and LTER site. Our history of fire-related research and long-term inquiry contribute to our existing knowledge of fire in the region and provide us a unique opportunity to understand the consequences of these large fires on our complex mountain landscape. With these talks we hope to spark further discussions among the research community.
February Presentations:
“How do soil carbon dynamics respond to differing severities of fire disturbance?” presented by Kate Lajtha, Professor, Crop and Soil Science, OSU
"Long-term fire effects on soil C and N around HJA" presented by Steven Perakis, USGS Research Ecologist
Announcements and Reminders:
Our meetings follow the academic year. Future meetings: March 5, April 2, May 7, June 4. 9-11 AM.

The Fall 2020 issue of the Andrews Forest Newsletter, now online at https://andrewsforest.oregonstate.edu/publications/newsletter
In this issue we explore the recent wildfires that burned in the Andrews Forest and the fire’s effect on our landscape and research. Topics include:
Happy Reading!
The Holiday Farm fire ignited the night of September 7, 2020, south of the Andrews Forest. Fire entered the Andrews Forest on September 12, at the south boundary of Watershed 9, and progressed northward into Watershed 1, then Watershed 2. The fire burned mostly at low severity within the Andrews Forest, moving along the ground. We see small areas of canopy tree death in these watersheds, where fire continues to smolder in large snags, logs and roots, and could overwinter as embers to reignite next spring.
The Holiday Farm Fire playlist on the Andrews Forest YouTube channel features short video clips on the fire and fire recovery at the Andrews Forest. Walk through Watershed 1 just after the burn, watch an excavator replace soil and brush over fire lines, or see an Air Crane dropping water over Watershed 2 hot spots.
Our Photo Gallery features images from the recent Holiday Farm Fire, which burned in Watershed 1, Watershed 9, and Watershed 2. We will continue to post new images as they become available.
The Andrews Forest Program provides science on multiple themes and provides a broader foundation for regional studies.
