Snowdown 2019
Winter Conditions: limited access
News Brief Description:
Headquarters and the research facility were affected by heavy snow and falling trees. Due to fallen trees on all roads, access to the site is limited. Check conditions before traveling to the site.

Students Study Effects of Drought
A recent publication out of the HJ Andrews Experimental Forest LTER site illustrates the role that summer research experiences can play in contributing to LTER science and in engaging and mentoring students. Oregon State University graduate student Matthew Kaylor is the lead author on a paper about how trout and salamanders respond to drought. Kaylor wrote this paper in collaboration with two undergraduate students. The first student, Brian VerWay, worked with Kaylor to survey trout and salamanders in a set of streams in the Andrews Forest in 2014 and 2015.

Dissertation seminar: “Biogeochemical signals of watersheds’ response to disturbance”
Event Date:
Wednesday, November 7, 2018
Event Brief Description:
Francisco Guerrero-Bolano, PhD Candidate, Sustainable Forest Management and Water Resources Science. Major professor: Jeff Hatten
Dissertation Defense: “Biogeochemical signals of watersheds’ response to disturbance”
In his research, Francisco looks at long-term records (30-1500 years) of biogeochemical signals that result from the interaction between streamflow, sediment transport and nutrient cycling in forested landscapes. Francisco combines detailed physical-chemical analysis of sediments with fundamental principles derived from the mathematical theory of information to gain mechanistic insights on ecosystem behavior. By understanding the biogeochemical signals of watersheds response to disturbance, Francisco’s research aims to gain insights into integrated resilience assessments in forested watersheds of the Pacific Northwest.

Spring 2018
LTER Monthly Meeting. March 2, 9-11 AM. Looking at drought, Part I
Event Date:
Friday, March 2, 2018
Event Brief Description:
We’ll share a collection of data and short presentations from PIs on the drought year of 2015, to see how various data collection efforts align (or don't) in a year that may be representative of future climate conditions in this region.
Immediately following the talks, the general meeting will include updates on proposals, graduate students, Willamette National Forest partnership, site use proposals.
Graduate student highlight: “Modeling canopy architecture and crown interlocking effects by using point clouds” presented by Rong Fang, PhD student in the Department of Forest Engineering Resource and Management.
Monthly meetings are used to share science, news, and opportunities related to the HJ Andrews Experimental Forest and Long-Term Ecological Research program. We start with a science hour and then move into program news and announcements. Anyone is welcome to attend. Monthly meetings are on the first Friday of the month during the academic year, from 9 AM - 11 AM.
Forestry Sciences Lab, 3200 SW Jefferson Way, Room 20. 9 - 11 AM.
