Interview with Evergreen Undergraduate Kelly Zenn

If an animal represented your research methods, what would it be?

 “If I were to choose an animal that reflects my research style it would be a crab: I’m a bit protective of my work, always triple checking everything, moving backwards as much as I move forward.” 

What attracted you to this research?

“I learned about Carri’s work when she sat as a panelist for an event my film class put on “Waters Connect Us: A conversation about protecting and restoring water with Indigenous Communities, Environmental Scientists, and Media Creators” in 2019. I was intrigued by the unique opportunity to study newly formed watersheds on Mount St. Helens. It seemed to intersect perfectly with my interests in restoration ecology and I was inspired by how this research could be applied to environmental justice.”

What do you love about MSH?

“I grew up in Kentucky, the land of soft, rolling hills. When I moved out West I knew only of the story my parents told about visiting the Mount St. Helens with my sister before I was born—how, when the curtains parted at the visitor center to reveal the volcano—my sister burst into tears, terrified by the destruction she had just seen on film. I always expected to feel that same fear. When I took my first steps through the Pumice plain, however, I was reminded of a quote from Robin Wall Kimmerer’s Braiding Sweetgrass that reads, “a basket knows the dual powers of destruction and creation that shape the world. Mount St. Helens knows of these powers, too, of course. The eruption laid bare the conditions for new life to take hold and the fields of wildflowers now stand as a gentle reminder that things do not end with tragedy; there is always another page.”

Do you identify as a Greener?

“I do, but I haven’t always. In identifying as a Greener, I’m grateful for the talented, patient professors I’ve worked with, the expansion of my worldview, and peers that helped me form a more comprehensive moral framework. There are so many incredibly unique opportunities at Evergreen and supporting students doing graduate-level research as an undergraduate is just one example of Evergreen’s strengths. For this and much else, I’m proud to call myself a Greener.”

GEOGIRLS! Science Outreach

One of the most exciting outreach activities done at MSH is a geology and nature camp for middle school girls that focuses on engaging the youth in the amazing world of science. They are called the “GeoGirls” and are organized by the Mount St. Helens Institute! Watch this short video:

This unique opportunity allows middle school girls to join in on fieldwork on the Pumice Plain and learn about the history of the mountain. Encouraging and supporting the youth developing skills, knowledge, and memories they can take with them for a lifetime!

GeoGirls is a collaborative effort that runs during the summer where those involved get to learn from REAL SCIENTISTS! Our lab volunteered to teach the 2018 and 2019 GeoGirls to measure things like stream sinuosity and velocity of MSH watersheds! 

Benthic Macroinvertebrates of MSH

The eruption of Mount St Helens created pyroclastic flows, mudflows, and ash fallout that covered the Pumice Plain in over 100 ft of sterile material. Since then, new watersheds have formed, diverse fauna has colonized MSH streams, and our lab team has been there to document!

The benthic macroinvertebrates of MSH colonize, eat and utilize leaf litter that falls into streams. With the use of leaf litter bags, Undergraduates Angie Froedin-Morgensen and Brandy Ku’ualoha Kamakawiwoole spend hours under a microscope sorting these aquatic insects!

Aquatic insects like Ephemeroptera, Trichoptera, and Plecoptera all play a critical role in the aquatic food webs! Benthic macroinvertebrate communities provide amazing insight as indicators of biological conditions, and communities differ across MSH streams!  

Insects on Willows: Weevils, Beetles, Galling Herbivores

Willows across the Pumice Plain of Mount St. Helens provide more than just riparian vegetation! They provide shelter, habitat and food to a variety of insects. Insects like Chrysomelid beetle larvae chew their way through willow leaves!

Another insect that utilizes the willows is the stem-boring weevil, which is native to Europe but was introduced to Mount St Helens in 1989! The tiny long-nosed guys, show up a lot in our studies as they cause branch death and mortality of willows.

Insects like galling midges have specialized feeding behaviors that require willow leaves as a host. They create new microhabitats for their young via galling. Stay tuned to learn more about the aquatic macroinvertebrates that colonize willow leaves that fall into streams!
