Nachusa Smammals: It Takes a Village

In 2013, Dr. Holly Jones started conducting a long-term research project at Nachusa Grasslands on quantifying the effects of disturbance-related management strategies on small mammal populations at restored and remnant prairie sites. The reintroduction of bison in 2014 allowed for a powerful before and after bison impact study that documented the effects of bison grazing on the small mammal communities. Data collected on species responses to bison, prescribed fire frequency, restoration age, and vegetation composition will inform decisions regarding abundance and biodiversity for small mammals. Small mammals play important roles in the food web by influencing vegetation structure through herbivory and seed predation, as well as serving as prey for predator species. So far, plant communities with bison grazing are becoming more diverse and more abundant with small mammals. In the beginning, Dr. Jones ran the small mammal project by herself for a year until she was able to pass it on to her Master’s student Angela Burke in 2014. It was quite a challenge to run the project on her own, and volunteers have become an essential component to keep it going. Over the years, we have had more than 100 volunteers participate to help check traps in the morning and reset traps in the afternoon.  
Picture
Dr. Holly Jones and PhD student Erin Rowland bait the small mammal traps.
​On the first day of small mammal trapping, or as we like to call it “smammaling”, we prep 150 metal Sherman traps by baiting them with peanut butter and oats. Our small army of volunteers, 3 or 4 people, create an assembly line, with one person spreading just a dab of peanut butter on the backplate and the other sprinkling a small pinch of oats inside. Once all traps have been prepped, we start stacking rows of them, Tetris style, in the back of Scarlet, our NIU mule. 
Picture
Out of the four seasons we sample for small mammals, August and October have the tallest vegetation, making it difficult to locate our poles. We flag the highest plant we can find nearby; for me it’s usually prairie dock or good ol’ big bluestem, and we try to navigate our way through the meandering paths of the tallgrass prairie jungle."
​We take off to set 25 traps at six of our 5x5 grid sites, hoping our plans don’t get foiled by any bison delays or strange weather. Each site has flagged poles to indicate where the trap must be set; however, finding them can sometimes be a challenge. Bison love using our poles as backscratchers, and they are often found sprawled across the prairie. At each pole we place an open trap where it will sit until an unsuspecting critter passes by and catches a whiff of irresistible Jif. 
Picture
The mice spend the night at their “mouse hotel” feasting on peanut butter and oats until we are back to process them in the morning.
​I always get a rush of excitement as I walk up to a trap and notice the door is closed. When I peek inside the trap, I am usually able to see a little face staring back at me. Occasionally, I’ll get a trigger-no-capture and my excitement will fade to dissatisfaction. Likewise, thieves are a constant problem. Some especially small, speedy daredevils are able to run in to the trap, take some quick bites of peanut butter, and run out without triggering it. We keep tabs on which traps have been thieved and adjust/replace them accordingly.
Picture
Tail measurements are taken from a meadow jumping mouse.
​To process the small mammals, we record the weight and take measurements on the right hind foot, tail, and body using a caliper. In addition, we determine their sex, age, reproductive status, species, and PIT tag number. Some of the species we have captured at our sites and record data on include thirteen-lined ground squirrel, deer mouse, white-footed mouse, western harvest mouse, meadow jumping mouse, prairie vole, meadow vole, and masked and short-tailed shrews. The most common species we capture is the deer mouse, Peromyscus maniculatus. Depending on whether it’s a new capture or recap, we will carefully insert a PIT tag underneath its skin – similar to microchipping your pet – as a way to keep track of its movements, survival, and reproduction throughout the study. It’s always a treat when we have an overwinter or recapture from the previous year; they were the lucky ones to survive the long cold winter! Finally, we provide complimentary haircuts to all new buddies and collect the hair to run in the stable isotope lab. The information gathered from each sample result can tell us about their diet and role in the food web.

Dr. Jones' daughter, 5-year-old Aliana, is our smallest, but mightiest, volunteer.
​Since 2015, I have been volunteering with Dr. Jones’ small mammal project. This year I was given the opportunity to help run the project and process the small mammals until her incoming PhD student, Erin Rowland, arrived. I took up the challenge, and with practice I became a pro. I would say my favorite part of the job is meeting the volunteers and training them how to be great smammalers. I enjoy acting as a Nachusa tour guide to all newcomers, young and old.

Would you like to volunteer on the small mammal project?
​Although anyone is welcome to volunteer, the majority of our helpers are undergraduate students who enjoy a break away from the classroom. Volunteering for the small mammal project gets you to spend time outside, which is beneficial to your health and well-being. It inspires the public to engage in the scientific process, appreciate native plants and animals, and meet others who care about our environment. Furthermore, it helps develop team building skills that are important for any job setting. Volunteers are the heart and soul of the small mammal project, and without them I’m not sure it would be able to persist. There is a lot to accomplish within the 12 consecutive days we are at Nachusa smammaling, and any help is greatly appreciated! If you are interested in volunteering, please contact Erin Rowland. To me, the small mammal project is all about making new and old friends — volunteers and mice alike. 

Small mammal research has been supported by the Friends of Nachusa Grasslands science grants from 2015 to 2018.

Jess,
Your dedication and unwavering enthusiasm for the small mammal project at Nachusa is truly amazing! I will never forget your first day volunteering on the project when I was leading — I knew you were going to be an amazing field biologist!! Keep up the amazing work everyone and hopefully the still thanks the little buddies for their “science”. Cheers to many more years of amazing prairie and small mammal science !!!

Thank you for everything Angie! You were a great mentor/teacher from the beginning and I feel incredibly lucky to have had you as a role model during my undergraduate degree. As a student, you helped me realize and embrace all my amazing qualities. You've taught me there is no single mold or criteria when it comes to being a student in academia. Being different is a good thing and can be used to my advantage! Thanks for taking me under your wing and showing me how to become a "prairie guru". You have made a huge impact on the small mammal project at Nachusa and are part of the reason why it has become so epic!

Jess,

I love this!!! This is beautifully written and such an incredible homage to Holly, Angie, Kirstie, Nick, Erin, and all of the people who have given their time for the smammalling! Keep on doing the good work!!!

Thanks Jeff!!! I enjoyed writing it and thought everyone should know what it truly means to smammal. Indeed, all previous grad students have worked super hard on the project and deserve recognition!
