*Presentation Stations around Headquarters:

Attendees will rotate around four presentation stations in the morning (10:15 - 12:30 PM). Each stop is 25 minutes with 5 minutes to move to next station.

1. Does water really RUN downhill?
Come and challenge your perceptions of how watersheds (and airsheds) work. Leaders: Chad Higgins (Environmental Fluid Mechanic, OSU) and Steve Wondzell (Riparian Ecologist, PNW). (Location: Fire pit / tree-climbing station)

2. Meadows and Pollination Ecology
See a demonstration of a new remote monitoring system for hummingbird movements and survival (Adam Hadley, Matt Betts (Forest Ecosystems & Society, OSU)), learn how to identify a few of Oregon’s many species of pollinators (Andy Moldenke (Botany and Plant Pathology, OSU)), and learn about ongoing pollination research at the HJ Andrews (Julia Jones, Eddie Helderop (CEOAS, OSU)). (Location: meadow area at the start of the stream trail)

3. Forest Governance
Who decides how our national forests should be managed, and what factors influence their decisions? What role does science play? What role does landscape pattern and process play? Come hear about our plans to strengthen social science inquiry and integrate it with ecological research in our LTER program. Leaders: Hannah Gosnell (Geography, OSU), Harmony Burright (Geography, OSU). Location: Classroom

4. Arts and Humanities:
Browse among the displays and chat with the artists, composer, and historian. Leaders: Leah Wilson (artist), Rob Mutch (photographer), Sam Schmieding (historian), Justin Ralls (musician), Bob Keefer (photographer/artist), MC: Fred Swanson. Location: Conference Room


**Afternoon Field Trip Descriptions:

Attendees will choose from one of four field trips for the afternoon (1:30 - 4:00 PM). Sign-up sheets will be posted on site, on the morning of the event. Trip details may change slightly.


Spend a van-free afternoon exploring the Discovery Trail with Andrews researchers and educators. See how researchers are using new technology such as infrared imaging and integrated flourometery to understand connectivity through the lens of ecophysiology, linking long-term climate observations to new studies of canopy microclimate and plant stress. Field test an ecology lesson on forest trophic interactions developed through the Andrews Schoolyard LTER program. Learn about and partake in a citizen science collaboration to understand weather and plant phenology patterns across spatial scales. This trip will involve approximately one mile of walking on fairly level terrain on forest trails, and active participation in field research demonstrations and educational exercises.

Leaders: Jody Einerson (OSU Extension), Youngil Kim (Forest Ecosystems & Society, OSU) Kari O’Connell (Oregon Natural Resources Education Program), Mark Schulze (Forest Ecosystems & Society, OSU), Chris Still (Forest Ecosystems & Society, OSU) Brad Withrow-Robinson (OSU Extension)

Please bring rain gear and sturdy walking shoes.  Be prepared to walk on gravel roads and single-track trails, approximately 1 mile total.


The patterns and drivers of forest growth form the basis for how forest ecosystems work, but these factors can elude casual observation by the naked eye. We will discuss using airborne LIDAR to characterize forest growth patterns from above, how soil properties sustain forest growth from below, and what these mean for long-term functioning of forested landscapes. Leaders: Dave Bell (PNW): “Measuring forests from several thousand feet above"—looking at LIDAR.  Julie Pett-Ridge (Crop and Soil Science, OSU)/ Jeff Hatten (Forest Engineering and Resource Management, OSU): "What lies beneath?”—a hands-on experience with soil.  Steve Perakis (USGS): "Beyond the present: The past and future of long-term carbon and nutrient cycles."   Location: In and Near Reference Stand 2

Please bring rain gear and sturdy walking shoes. This field trip requires that participants can walk short distances on uneven single-track trails, with some fairly steep up and down hill sections. Some navigating around or over logs may be necessary.


Places where long-term research and experiments are conducted embody the connection between natural processes and humans, and can inspire creative writing about these connections. In this 2.5-hour trip, we will visit the site of a 200-year log decomposition experiment, discuss long-term research on decomposition and climate, and engage in a creative writing exercise. Participants will spend some quiet time alone in the forest. Leaders: Julia Jones (CEOAS, OSU), Tim Fox, Mark Harmon (Forest Ecosystems & Society, OSU). Location: Log Decomposition site

Please bring rain gear and sturdy walking shoes. This field trip requires that participants can walk short distances on uneven single-track trails, with some fairly steep up and down hill sections. Some navigating around or over logs may be necessary.


Join Andrews Forest scientists and graduate students as they share past and present research about streams and water, and involve you in hands-on activities. In this field trip, we will explore forest-stream interactions and discuss what influences the variation in hydrology and instream habitat and processes, and potential responses of fish and invertebrates. Activities will include sampling for fish, salamanders and macroinvertebrates, measuring instream habitats, and using tracer releases to examine streamflow, and quantifying water infiltration rates. Leaders: Sherri Johnson (PNW), Ivan Arismendi (Fisheries and Wildlife, OSU), Matt Kaylor (Fisheries and Wildlife, OSU), and Catalina Segura (Forest Engineering and Resource Management, OSU) Location: Lookout Creek RCC site and nearby small stream.

Please bring rain gear and sturdy walking shoes.  Be prepared to walk on a rough trails (up to 1/2 mile total) and slippery rocks.  


Forests are a symbol of Oregon’s environment and culture. But how might we decide to manage them? How can we overcome the conflicts that have plagued forest management in the past? On this field trip, participants will engage with forest scientists and managers, sharing ideas about how we might manage certain forest stands in the future. This is a chance to discuss the values and ethics you and others have about managing Oregon’s important forest resources. Leaders: Michael Paul Nelson (Forest Ecosystems & Society, OSU), Cheryl Friesen (WNF), Lisa Helmig (WNF), Chelsea Batavia (Forest Ecosystems & Society, OSU), Matthew Betts (Forest Ecosystems & Society, OSU). Locations: stands in and adjacent to the Andrews Forest.

Please bring rain gear and sturdy walking shoes.  Be prepared to walk for short distances on uneven terrain.
