December #SuperSnap

This month’s #SuperSnap features six sandhill cranes (Grus canadensis) from Waupaca County. Did you know there are many different titles for a group of cranes? This group could be referred to as a “dance,” a “construction,” or a “swoop”. Sandhill cranes migrate across our state every year and can often be spotted in open prairies and marshes.

November #SuperSnap

This month’s #SuperSnap features a tom turkey dressed up in his best bow-tie wattle and ready for Thanksgiving dinner! Turkeys use their wattles for a variety of reasons. This loose skin around their neck allows them to expel extra heat during the hot summer months. Male turkeys (toms) also use their wattle to attract female turkeys (hens) when blood rushes to the area, causing the wattle to turn a bright red color. If a turkey is frightened, blood may also rush out of their wattle, causing it to turn blue.

Exploring the Plant Side of Citizen Science

In the state of Wisconsin, we are lucky to have so many people who take interest in our natural resources. From the Snapshot Wisconsin project here at the Department of Natural Resources, to university professors conducting environmental research, to individual Wisconsinites, there’s no shortage of people who care.

Before I started working with the Snapshot Wisconsin team, I was fortunate enough to participate in another research project. The goal of the project was to look more closely at the impact that white-tailed deer have on Wisconsin forests when they browse on (or “eat”) sapling trees. My job was to use the Twig-Age method to help collect data across several forest patches in Southern Wisconsin, as well as to build a website to share this new method of data collection with other volunteers who wanted to participate in the research.

The Twig-Age method involves looking at a tree sapling, measuring its height, and counting the terminal bud scale scars along two of its branches. Terminal bud scale scars are what’s left behind on the twig when a bud falls off naturally during the growing process. Picture marking a child’s height on the wall each year. The more bud scale scars a twig has, the longer a twig has been able to grow without being browsed by a deer. We took hundreds of data points in order to paint a picture of what sort of browsing impacts deer were having on these forests.

While I was doing this field work, I found myself surprised by how many different species of trees we have in our forests. Usually when I walk through the woods, I don’t take the time to notice all the different plants around me. I notice the birds and the squirrels, but the plants have always been more of a beautiful backdrop. This research project gave me a stronger appreciation for the diverse vegetation that we have in our forests. I had time to get down at eye-level with these saplings and really look at them. It was like playing the part of a historian by recording the age of their twigs and whether or not a deer had eaten from them before. Each data point collected was a personal interview with a tiny tree.

By the end of the summer we created Our Wisconsin Understory, a citizen science project for monitoring deer impacts. The goal is to collect as much data as possible and to hopefully expand data points across the state. Anyone interested in learning more about the Twig-Age method and collecting data for the project can do so at the Our Wisconsin Understory website.
