B is for Bison at Nachusa Grasslands

“At once [the buffalo] is a symbol of the tenacity of wilderness and the destruction of wilderness…it stands for freedom and captivity, extinction and salvation.”—Steven Rinella

Let’s take a hike “where the buffalo roam.”

Bison (Bison bison).

I’m chasing dragonflies at one of my favorite preserves in Illinois: Nachusa Grasslands. Approximately two hours west of Chicago, Nachusa Grasslands is a 3,800-acre mosaic of tallgrass prairies and savannas. Woodlands and wetlands. Today, as a dragonfly monitor at Nachusa with access inside the bison unit, I hope to collect Odonate data at one of my favorite pond routes. But the bison have other plans for my morning. As I wade into the wetland surrounding the pond, admiring the dragonflies…

Common whitetail dragonfly (Plathemis lydia).

…I hear a bellow. Uh, oh. That’s the sound of a bison bull kicking up some trouble.

When you’re working in a bison unit, you don’t wait around when you hear that sound. I immediately head for my car. It doesn’t take long. Here they come!

They make a beeline for my dragonfly pond, ready to join the frogs and cool off on this sunny morning.

I enjoy watching them wade into the water and graze on the juicy vegetation. But time passes. My plans for collecting dragonfly data this morning are shot. These bison aren’t going anywhere soon.

I make myself comfortable in the car, hoping they’ll eventually move on. I don’t get out. Bison are one of the most dangerous animals in North America. Males may weigh more than 2,000 pounds. And—they’re fast! I’ve watched them tear across the prairie at top speeds of 30 mph for no apparent reason. It’s important to respect these incredible animals.

I only take photos of bison with a zoom lens from the safety of my vehicle. Even then, while working in the bison unit, I’m careful to keep my car a good distance away.

Bison can jump, too! Up to six feet. They won’t let a fence keep them from something they really, really want to do. I admire that kind of determination.

I’m grateful for the bison at Nachusa—and not only because I enjoy watching them. Without them, the prairie is incomplete. They are an important piece of the prairie puzzle. As they wallow and churn through the prairie with their hooves…

…they create spaces for other members of the prairie community to thrive.

Bison grazing habits may also free up space for prairie wildflowers.

Great blue lobelia (Lobelia siphilitica).

They also fertilize the prairie with their dung. Bison patties! Good stuff for prairies.

Time passes. The bison show no sign of leaving. Looks like it’s going to be “Plan B” today. I start the car and back up, then turn around on the gravel two-track. I’ve got plenty of alternatives besides this pond for a dragonfly-chasing hike. So many exciting areas to explore!

With so many wildflowers in bloom at Nachusa…

Monkeyflower (Mimulus ringens).

…and plenty of other interesting prairie creatures around….

Short-horned grasshopper (Family Acrididae).

… my alternative hike on the prairie this morning will still be time well spent.

The bison are fun to see, but they’re only a bonus on a trip to Nachusa. There is so much else to discover!

Why not go for a hike and see it for yourself?
