seeking summer interns for stream research
News Brief Description:
Seeking two students (undergraduate or graduate students)
The first part of the summer will be spent collecting detailed physical and biological data, using established protocols, in a major river restoration project on the S. Fork McKenzie River.
The second half of the summer’s work will involve an extensive, road-based, rapid-monitoring effort to characterize flow permanence in headwater streams. Interns will use high resolution GPS and tablets to collect observations for headwater streams on federal forest lands throughout western Oregon.
More information (pdf).
Applications will be reviewed starting 15 March 2020. https://jobs.oregonstate.edu/postings/89002

Andrews Forest Monthly Meeting, Nov 1
Event Date:
Friday, November 1, 2019
Event Brief Description:
Presentations: Science and Art in the Lookout Creek Watershed
- Ivan Arismendi Aquatic vertebrates of Lookout Creek (15 min). Ivan Arismendi will summarize findings from about stream habitats and aquatic vertebrates from synoptic sampling in Lookout Creek this summer.
- Leah Wilson Artwork inspired by Lookout Creek watershed (45 min). Leah Wilson will show her art that is inspired from Lookout Creek, why she continues to create art from the Andrews Forest, and she will introduce the concept for the Peavy project.
Presentations are followed by sharing announcements across the program.
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. The next meetings will be December 6, January 10, Feb 7, March 6, April 3, May 1, June 5.

70 year anniversary of stream gage data
News Brief Description:
It was 70 years ago this month (25 August 1949 to be precise) that the US Geological Survey (USGS) started gaging Lookout Creek of the Andrews Forest. Harry S. Truman was president. While the official record starts on 1 October 1949, gaging was already underway; we have a copy of the A-35 chart to represent the 25 August start. The USGS maintains the stream gage to this day, but the Andrews Forest PNW/LTER record is the only complete record of stream discharge on Lookout Creek. The PNW/LTER mined records from the National Archives through the USGS Portland Oregon Water Science Center to digitize, enter, and otherwise reconstruct an hourly record starting in 1949 through 1986 where the USGS high temporal resolution record begins. This long-term data set (HF004) is unique in its extent and availability among Pacific Northwest streams.
MS Defense: Allison Swartz. Stream Temperature and Primary Producers
Event Date:
Thursday, June 6, 2019
Event Brief Description:
Please join us on Thursday, June 6 at 2:00pm in Richardson 115 for a presentation of Allison’s thesis, titled: “Stream Temperature and Primary Producer Responses to Riparian Canopy Gaps Over Forested Headwaters.” Allison is pursuing her MS in Forest Ecosystems and Society with Dr. Dana Warren. Please contact the FES Department at (541) 737-2244 with questions or for accommodations for disabilities.
Thesis Defense Seminar on Oregon Streams
Event Date:
Thursday, May 9, 2019
Event Brief Description:
"Bottom-up drivers of primary producers and predator populations in Oregon streams"
Understanding factors limiting food web productivity is important to effective management of stream ecosystems and biota. Two key resources that influence productivity at the base of the food web are light and nutrients. Come hear about how two widespread anthropogenic modifications to stream ecosystems of the Pacific Northwest — riparian harvesting and the reduction of naturally spawning salmon — have altered light and nutrients in streams and how these changes may be impacting stream food webs. The first half focuses on how riparian stand development processes following historic clear-cutting influence stream consumers through bottom-up processes. The second half evaluates how the drastic reduction in spawning salmon in NE Oregon may be influencing stream food webs, and in particular juvenile Chinook Salmon and steelhead.

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.
