Andrews Forest Monthly Meeting April 2

Event Date: 
Friday, April 2, 2021
Event Brief Description: 

Andrews Forest Monthly Meeting: Friday, April 2, 9-11 AM

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 H. J. 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.

Presentations:

"Wildfire and post-fire forest management effects on water quantity and quality" presented by Kevin D. Bladon, Associate Professor, Forest Engineering, Resources, and Management, Oregon State University

Willamette River microbes from headwaters to mouth: links to landscape, travel time, and fire" presented by Byron C. Crump, Professor, College of Earth, Ocean, and Atmospheric Sciences, Oregon State University

Hybrid Vigor; Ecology X Art X Design" presented by David Buckley Borden, Visiting Professor, Department of Landscape Architecture, College of Design, University of Oregon.

Graduate student flash presentation: "Modeling channel change in Lower Lookout" presented by Leah Cromer, MS student with Julia Jones, Geography.
 
After our presentations, we will move into our community meeting to share about new publications, new faces, and updates from our WNF partner, graduate students, and education and outreach. 

Our meetings follow the academic year. Future meetings: May 7, June 4.  9-11 AM.

Emily Crampe MS Defense. May 11. 2:30 PM

Event Date: 
Monday, May 11, 2020
Event Brief Description: 

MS Defense: “Forest succession and climate change effects on long-term runoff coefficients at varying timescales.”

Emily Crampe is completing her degree in Water Resources Science under her major professor Catalina Segura.

Forest harvesting and climate change induced shifts in precipitation characteristics (i.e., intensity, type) may affect how water is stored on the landscape. In this study we used long-term paired watershed data to assess these possible changes by examining how much of the incoming precipitation was translated into the streamflow on the storm event, seasonal, and annual timescales.

Segura CAREER Award

News Brief Description: 

Catalina Segura, Andrews Forest researcher, received a National Science Foundation Faculty Early Career Development (CAREER) award, one of the NSF’s most prestigious honors. The award, titled “Unveiling the role of catchment physiography in the hydrologic response of headwater streams,” supports Catalina’s research on the temporal-spatial variability of rainfall-runoff generation in headwater streams, including streams at the Andrews Forest. Catalina shares, “Water quality and availability are vital to society and wildlife sustainability. However, we are still not able to predict the paths that water follows from precipitation to streamflow in a river, nor how long this process takes. A deeper understanding is crucial to anticipate overall water quality and supply. This is particularly true for headwater streams because their input controls the water quantity and quality of larger freshwater systems. While it is widely recognized that the flow paths water can take depend on the available catchment storage, i.e., the size of the underground “bucket”, it is not yet possible to measure how large this storage is. This project will investigate the relationship between geology, geomorphology, and topography and storage availability, as derived from hydrologic tracers such as water stable isotopes. The work will enhance societal ability to adapt and ensure sustainable supply of clean water under modified hydrologic conditions, likely to occur as consequences of human activities (forest harvesting, urbanization) and climate change.” 

Catalina plans to conduct much of her research at the HJ Andrews Experimental Forest Long-Term Ecological Research (LTER) site, in western Oregon. The LTER program, says Catalina, offers “access to high-quality, long-term hydrologic data in a landscape that is still puzzling.”

In addition to her connection with the Andrews Forest LTER Program, Catalina will work with the Oregon Museum of Science and Industry to develop hands-on activities and to teach the general public about water availability in the context of climate change.

Catalina is an Assistant Professor in the Department of Forest Engineering, Resources & Management in the College of Forestry at Oregon State University. https://directory.forestry.oregonstate.edu/people/segura-catalina
