Interview with Evergreen undergrad, Iris Garthwaite ‘20

“It’s unconventional, but I view ecological studies as a radical form of generous listening to the world around us. My current listening project (research) investigates the temporal dynamics of multitrophic interactions in aquatic-terrestrial ecosystems.”

“I am currently studying interactions between Salix sitchensis phenology, phytochemistry and stream biota at MSH. Advancing our understanding in this research area allows for better predictions of climate -driven ecological mismatch in land-water ecosystems.”

“Research at MSH with Dr. LeRoy has allowed me to:

  • Participate in NSF- funded research
  • Conduct independent stream ecology research
  • Co-author a peer-reviewed publication
  • Form strong relationships with peers and mentors
  • And so much more!”

“I am passionate about supporting other #WomenInSTEM and connecting youth with nature. I have such a supportive group in the L3 lab and I want to give others that same feeling of comfort with science and the natural world.”

“I am so excited to have two manuscripts in progress as an undergraduate. The sky is the limit for research opportunities at Evergreen. I am looking forward to publishing our research and sharing our work with the broader freshwater ecology community.”

“Research is an art form of listening, sometimes it is with a hyporheic well, an extraction, a pH meter, a mass spectra or simply sitting by the stream. Evergreen is my academic home, it understands my way of listening and my desire not to push my way into an answer but to find patterns and relationships in a landscape of uncertainty and null hypotheses.”

“Instead of starting with the question- what do I want to discover? I like to enter a new study system with “what wants to be discovered?” I come from a background in permaculture, where we are taught to watch the land for quite some time before jumping in and making changes. Where does the shade hit in November? What family of plants sprout in February? Where does rain collect in December?  That’s the kind of science I like to do- meaningful, thoughtful and full of listening.”

3-year Permit to do Research at Mount St. Helens

With the Mount St Helens National Volcanic Monument as a protected landscape, our team has a 3-year permit to do research on the Pumice Plain. We hike several miles to reach our study sites, often packing along heavy equipment, but the views of the volcano are worth it!

Our research in the newly formed watersheds of the Pumice Plain includes chemical analysis and water quality sampling. These data help us to understand the potential differences in water sources across Pumice Plain watersheds and predict influences on ecosystem function!

The most important thing in field work is proper documentation! What may seem like a tedious task, is a vital component of ensuring our team can continue publishing data about the primary succession of riverine communities at Mount St. Helens! Thanks to Evergreen State College for the great photos!

Collaborators- involvement outside of Evergreen!

Here are a few of the fantastic collaborators that we’ve been fortunate to have on our team!   

Shannon Claeson (USFS Aquatic Ecologist; @ForestServiceNWhas been working at Mount St. Helens for over 10 years and collaborating with us for the past five years. She brings expertise in aquatic insect taxonomy and ecology to the team.  

Dr. Debra Finn (@streambug) is an assistant professor at Missouri State University (@MissouriState) and collaborates with us on hyporheic flows, stonefly secondary production, and invertebrate genetics. She received an NSF-ROA extension grant to collaborate with our team! 

Joy Ramstack Hobbs is a limnologist from the Science Museum of Minnesota/St. Croix Watershed Research Station and is senior personnel on the NSF EAGER grant. Joy provides expertise in phycology, statistics and undergraduate training and been a great collaborator the past 2 years! 

 

It’s hard work hauling well pounders and hyporheic wells out to the field site. Dr. Deb Finn collaborated on hyporheic zone studies in summer 2019.

Data Collection in Newly Created Watersheds at MSH

When Mount St. Helens erupted, it resulted in a massive landslide that buried existing forests, streams, and watersheds. Since the eruption, five (5) novel watersheds have developed on the Pumice Plain. These streams on the north face of MSH have been our team’s main interest. 

Undergraduates, faculty and collaborators have been able to conduct studies on environmental variation and biotic communities across these watersheds to address in-stream primary succession because of the unique ecosystem the eruption of MSH created.

We are especially interested in how riparian plants influence stream channel dynamics, increase shade, and input organic matter to these newly developing streams. Stay tuned for more about how willow sex differences and a wandering weevil alter in-stream ecosystem function!

Field work involves a lot of hiking!

The past 3 years our team has been working under an NSF EAGER grant to Dr. LeRoy which allows undergraduates at The Evergreen State College to gain amazing field experiences and research opportunities. 

Our team is composed of undergraduates, SURF students, research assistants, faculty, and many wonderful collaborators (stay turned to learn more about our collaborative work) that dedicate their summers to exploring the landscape of Mount St. Helens (MSH). 

MSH is an exemplary ecosystem for our team to study how the flora and fauna are responding to large, intense disturbances as well as their processes of early succession.
