A familiar path leads to an unexpected and rare discovery

Wed, Aug 13, 2025

This summer, TJ French begins each day with a familiar routine. From his apartment located on the east side of campus, he heads on foot through the university鈥檚 100-acre Ecosystem Preserve. 
 
鈥淭hat commute through the woods every morning is a good buffer for me between waking up and being at work,鈥 said French 鈥28, a double major in computer science and environmental science from Petersburg, Michigan.

Establishing regular rhythms

When French arrives on the other side of the woods, he鈥檚 at the university鈥檚 Lake Drive greenhouse, where he begins each day meeting with fellow students on the ecological restoration crew鈥攈is research team for the summer. 

The team spends time transplanting native plants at the greenhouse and then plants, mulches, and installs curb-cut rain gardens and parkway pocket gardens at various locations throughout the city. These activities result in slowing down stormwater that otherwise heads directly to Plaster Creek along with the pollutants from roadways and yards, affecting water quality in the creek for people and creatures downstream. 
 
鈥淲hen I signed up to be part of the crew this summer, I didn鈥檛 know more about the Plaster Creek Stewards than the paragraph on the signup sheet,鈥 said French. 鈥淏ut I knew it was this organization helping to restore the watershed and it was a job working outside, so that sounded cool.鈥 
 
French, alongside students and faculty, are daily working on restoration efforts within one of west Michigan鈥檚 most contaminated watersheds. His work has a fairly predictable rhythm. But one late July morning was anything but textbook.

Making a rare discovery

On this day, French and his fellow Calvin students joined local experts and community partners to help with their mussel survey research. 
 
Donned in chest-high waders, French set out into the creek in a local park and begin to run his hands along the creek鈥檚 floor. The goal was to find mussels, pull them up, identify them, and then place them safely back in the water. 
 
鈥淲e went into this hoping to find maybe five or 10 mussels,鈥 said French. 鈥淎nd we found hundreds of them.鈥 
 
While the volume of mussels they found was impressive, French made one of the rare discoveries of the day鈥攑ulling up a lilliput鈥攁 state endangered species. 
 
鈥淚t was a big surprise,鈥 said French. 鈥淚t was really cool to find something you weren鈥檛 expecting. Finding those couple of important species was really exciting and a cool discovery.鈥 

鈥淭his is the kind of ecological surprise that reinforces everything we鈥檙e doing to restore this space,鈥 said Andrea Lubberts, program manager for Plaster Creek Stewards. 鈥淢ussels are like the 鈥榣ivers of the river鈥欌攆iltering water, stabilizing stream beds, and signaling overall stream health. The fact that they鈥檙e here in these numbers tells us we have something to preserve as well as restore for the future of Plaster Creek.鈥

Confirming Calvin to be the right fit

French and the team鈥檚 discoveries this past month hold importance for the work being done to restore the watershed. And his experience on this team and through his studies at Calvin has reinforced his college decision. 

鈥淚 visited a lot of schools in my last year of high school, and Calvin was just one them. My general conclusion from visiting was they were all kind of the same, so it was hard to decide in the end,鈥 said French.  
 
But he said the fact Calvin is a Christian university played a major factor in his decision to enroll and reinforced his decision to continue his studies on the Grand Rapids campus. 
 
鈥淚 definitely value my faith very highly, and I want to continue to put my faith first in my life,鈥 said French. 鈥淚 went to a public high school, so this was my first experience with Christian education, and it鈥檚 been really good to see how faith can be integrated into science courses and STEM courses, to see there鈥檚 a scientific explanation for everything and a religious explanation for anything that exists, and they are connected.鈥
