Vegetation Response to Fire in a Young Forest
There are few studies of vegetation responses to fire in young forests of the western Cascades, in contrast to a rich history of study in older forests.

PhD Defense Adam Sibley

Event Brief Description:
Adam Sibley PhD Defense
Friday, June 11, 1 PM on zoom*
"Plants and their Environment: Assessing tree canopy microclimate and the response of trees to environmental stress in a diversity of forest types"
Adam has done field work, lab work, and computer modeling to assess the physiological response of plants to environmental stressors. His work has focused on the most impactful changes that have been forecasted in each ecosystem where he has worked. Adam's work on Douglas-fir foliage at the HJ Andrews Experimental Forest in Oregon focuses on dew formation during the dry season -- a potential water subsidy when water stress is at its peak. On the Big Island of Hawai'i, Adam studied the relative capacity of koa and ohia trees to adapt to drought stress. In Los Alamos, New Mexico, he examined adjustment to the photosynthetic machinery of pinon and juniper trees to a hotter baseline existence and to episodic heatwaves. In this defense, Adam will recount how these assessments were made, and how applying the tools he used will help us understand plant responses to environmental changes in the future.
Major professors: Dr. Chris Still and Dr. Rick Meinzer

Taking the temperature of forest canopies
Temperature is a primary control on ecological systems and processes, ranging from enzymatic reactions to tree growth. Temperature is also a fundamental characteristic of climate. Indeed, much of the concern about the impact of climate warming on ecosystems is motivated by the pervasive influence of temperature on organisms like plants. Although scientists often focus on air temperature, the actual temperature of a plant is more relevant; a plant’s temperature can depart from air temperature by 10-20 degrees Celsius.
Job posting - Veg Crew
News Brief Description:
Summer Field Crew Opportunities
We are looking for two (2) crew leaders and six (6) additional crew members to work on a long-term study of forest dynamics in the Pacific Northwest. We seek individuals who are interested in ecological research and enjoy working outdoors as part of a team.
The field crew will navigate off-trail to relocate permanent plots and identify, tag, measure and map trees. The crew will be based at the HJ Andrews Experimental Forest where housing is provided at no cost. Some camping will be necessary for sites located in Washington.
More information see HJA_VegCrew2021_announcement.pdf or contact Andrew Bluhm, Department of Forest Ecosystems and Society, Oregon State University.
Job openings for vegetation crew summer 2021
News Brief Description:
The LaManna lab in the Department of Biological Sciences at Marquette University is currently looking to hire one lead research technician and two research assistant positions with experience in forest-survey techniques and/or Pacific Northwest herbaceous plant identification skills to address questions related to the maintenance of plant species diversity in old-growth forests along a 1,300 m elevational gradient in the Western Cascade Mountains of Oregon. Positions will run from early May through Sept. 2021.
All applications for this position must be received through Marquette University’s electronic recruiting system: https://employment.marquette.edu/postings/14168

PhD Defense: Measuring and Modeling Crown Structure
Event Date:
Wednesday, May 6, 2020
Event Brief Description:
"Measuring and Modeling the Crown Structure of Coniferous Trees with Point Clouds Data," PhD defense by Rong Fang. May 6, 3 PM, via Zoom*.
This project digitized Loblolly pine and Douglas-fir trees using photogrammetric and laser scanning point clouds. Stem and branch structural attributes were estimated with point clouds data. We demonstrate point clouds are the data source of forest inventory for the new era.
Rong is earning her Ph.D. degree in Sustainable Forest Management, in the Department of Forest Engineering, Resources and Management, under major professor Dr. Bogdan Strimbu.
