Summer Fellowships 2025: Summer Shepherding With Tending Tilth

This blog post is part of the ESC Summer Fellowship 2025 series. These fellowships provided funding for research projects related to the environment, sustainability and/or the Climate Action Plan. This post was written by Grace Lounds, one the fellows of this past summer cycle.


For the past three summers now, Tending Tilth has taken on interns from K College to aid in sustainable sheep grazing. My name is Grace Lounds, and I am one of these interns! The other two this summer are Lauren Stallman and Gwen Crowder Smith, and together we have worked under Lauren Burns, getting gritty with plenty of hands-on farm work. This opportunity will likely be available to K College students in future years, so I wanted to share some of the valuable lessons I’ve learned (and the fun I’ve had) for anyone curious about sustainability, sheep, or maybe thinking about following in my footsteps!

About Tending Tilth and Sustainable Grazing

Tending Tilth is a contract-based sheep grazing business. This means that different clients hire us to bring sheep to their properties as an alternative to conventional machine mowing. Founded and operated by Lauren Burns, Tending Tilth functions year-round under her direction, with support from us summer interns.


The work we do has numerous conservational benefits for the ecosystems we graze. Sheep eat invasive species such as spotted knapweed, (as well as other unwanted plants like poison ivy), promoting native plant communities and biodiversity. Grazing also mechanically changes the landscapes we visit. When sheep graze, they trample down plants, stimulating plant growth, pressing dead plants into the soil, and pushing seedheads into the ground. This simultaneously presses their own manure into the soil, fertilizing the soil without harmful chemicals. Their urine also acts as a very nutrient-rich water resource for plants and microorganisms. Through these combined actions, (nutrient cycling, soil aeration, and organic matter incorporation), grazing helps build topsoil, promotes biodiversity, and strengthens root systems. Strong plant growth sequesters carbon and prevents drought.
Currently, Tending Tilth is working with GVSU Geology Department ‘s Professor Tara Kneeshaw to study soil health, proving that sheep grazing helps to sequester carbon. This is a study that will take 3 years, but preliminary findings already suggest that Tending Tilth’s practices enhance ecosystem health and contribute to climate change mitigation.

A Day on the Farm

Tending Tilth has about 80 sheep. Right now our sheep are split into two groups, the working group and the lambs, who are chaperoned by their grandmas and a couple male sheep. The lambs stay at the farm while the working group rotates from site to site, meaning that every day looks a bit different for us depending on where we are. The first thing we do when we get to a new site is to survey the land and make a plan for fencing. We use electric fences that we put up at each new location. Most of my time is spent putting up fences and taking them down later. Other chores include filling water tanks and setting up shade sales. Free time is spent making sure the sheep are happy and healthy. The male sheep can be quite cuddly, so I love giving them head scratches and patting their chubby bellies. I’ve also aided in hoof trimmings, fly bite treatment, giving shots, and deworming sheep.


The sheep are by far the most exciting part of the job. They’ve really stolen my heart, so much so that I am now seriously considering going to a large animal vet school after I graduate. My favorites are King Louis who’s part of the working group. He has a big personality and always runs right up to me and scratches his head on me. Gus is also a cutie. He’s only a few months old and he looks like a baby deer. He’s the nicest lamb from this season and likes to follow the adult sheep around. He used to be pretty shy but he’s really warmed up over the summer.


I could go on and on about all the sheep and their personalities, and all of the fun things I’ve done over the summer like installing a monitoring well or doing soil samples, but I think that’s all I’ll share to keep this short and sweet!

Welcome and Welcome Back for Fall 2025!

From everyone here at the Environmental Stewardship Center, welcome and welcome back to Kalamazoo College for the fall 2025 trimester! In honor of the new term (and our new first years), we’ve put together a list of what the ESC has to offer, events you can expect from the ESC this term, and resources to get involved!

The Lillian Anderson Arboretum is our one off-campus green space, located roughly 5 miles from K’s campus. It is roughly 140 acres, contained marshes, pine forests, and meadows, all interconnected through miles of trail pathways. The arboretum is an integral component to living green here at K. Not only is it used by classes as a learning lab (like the Arboretum P.E. class running this fall), but the arboretum has also been the source of numerous SIPs throughout the years and is continuously maintained by our student Arb Crew. Additionally, it’s enjoyed by the public and students in their free time; in fact, the arboretum is open from dusk to dawn!

Upcoming events to look out for: There is a Trip to the Arb scheduled for Wednesday 10/8 from 4:10-6:15pm – transportation provided!

One of the major components of the Climate Action Plan is promoting zero-waste on our campus, and the most important way we do that is through our composting program! With the support of the ESC and Facilities Management, the composting program is run by students who are a part of the Compost Crew. These students help collect food waste from students, faculty, and staff with their green compost buckets stationed throughout campus – you’ve probably already seen one!  

You can find the composting program in the Grove, the wooded area located next to the Living Learning houses and the Dewaters residence hall. Feel free to stop by, pick up your free compost bucket, and help our campus strive towards being zero-waste!

Upcoming events to look out for: Smashing Pumpkins, a Halloween-themed event where students are encouraged to smash old, leftover pumpkins from the fall season (and the scraps are then composted!)

Through student initiative and faculty support, our campus is lucky enough to have our very own hoop house, a type of unheated greenhouse! Located behind the Fitness and Wellness Center, the Hoop House has been the source of SIPs, classroom activities, club events, and more! Here you can visit during open hours (every Monday, Wednesday, and Friday from 4:30-6:00pm) to learn more about growing fruits and vegetables, get your hands in the dirt, take some fresh produce home, or just to enjoy the company of other sustainability-minded students! 

Upcoming events to look out for: the annual Harvest Festival, where current students, faculty, and staff can mingle with alumni and community members to celebrate the Mother Corn grown at the Hoop House, enjoy some fresh food, and build bridges with the great K community!

Hoop House Spotlight!

Spring is in full swing all around campus, and the perfect spot to enjoy the warmth and greenery is in the Hoop House! We’re taking a moment this week to highlight what’s growing and going on in the Hoop House this spring!

Visit the Hoop House!

Everyone is welcome at the Hoop House! Located behind the Fitness and Wellness Center, the Hoop House gardens are available to all of the campus community. Come drop in to open hours, which take place every Monday, Wednesday, and Friday from 4:30-6pm. You’re welcome to come in and work on gardening projects, harvest from fruits and veggies to take home with you, or just stop in to hang out! All the harvestable plants will be listed on the whiteboard, but here’s a list of what’s growing in the Hoop House!

  • End-of-cycle (so take them home soon!): kale, spinach, chives, and other greens
  • Ready to harvest: lemon balm, thyme
  • Growing stages: potatoes, radishes, squash, tomatoes, garlic, eggplant, snap peas
  • Growing in flats: bee and butterfly friendly flowers, corn
  • Other fun things: the peach tree is blossoming right now, and the fig tree grew a little leaf!

Meet the Crew

The Hoop House is up and running thanks to a phenomenal crew of students and staff who are passionate about green and growing spaces on campus! Hoop House Interns work with ESC Staff and Lee Arbogast to assist with the management of and care for the Hoop House gardens. During the Fall and Spring terms, they host regular open gardening hours for students, staff, and the greater Kalamazoo community and organize events using their own produce.

Winter in the Living Learning Labs

Lillian Anderson Arboretum

Winter can be one of the most beautiful times to visit the Arboretum! With pine trees blanketed in snow and the stillness of frozen ponds, you’ll get to see all kinds of winter nature and wildlife. It’s the perfect season for a chilly hike with a warm drink – you can walk, hike, and run all year long in the Arb!

This winter, you might run into some of our ongoing projects and programs! A carbon sequestration survey is currently taking place at the Arb. Part of a project that occurs every 5 years, this survey will help us better understand how trees utilize atmospheric carbon, and how the Arb functions as a carbon sink. You might also wander past folks with maps and compasses – don’t worry, they’re not lost! They’re just participating in a map and compass workshop put on by the Outdoor Leadership Training Center.

Be sure to layer up! In the colder weather, consider bringing an extra warm layer, hat/gloves, and shoes with good traction. All trails are open and operating as normal regardless of condition, unless otherwise noted. The Arb is open for normal hours, from dawn to dusk.

The Grove

The weather might be cold, but the compost piles are still warm and working hard! Thanks to the efforts of the Compost Crew, composting is available all winter long. Drop by the Grove (located behind the Living Learning Houses between Monroe and Lovell St) to pick up a compost bucket. Simply fill it up, drop it off, and pick up an empty one again!

The Hoop House

The Hoop House is still operational, even in the winter! We’re busy prepping flats and preparing for spring. Stay tuned for more info on a few open hours in late February and early March, and then get excited for full open hours to resume every MWF in April, 4:30-6pm!

Jolly Gardens & Dow Wildflower Garden

The Jolly Gardens and Dow Wildflower Gardens are getting through the winter season! While we might not be able to see the plants while walking by, this cold spell is helping prepare them for the next growing season. The leftover stems and plant matter we can see through the snow makes a great habitat for overwintering pollinators and other helpful insects!
