If you have recently taken a walk through the Arb prairies, you probably noticed the golden grasses swaying in the breeze and a few vibrant purple asters hiding in the thatch but did you realize that you were walking through one of the most diverse and endangered ecosystems on the planet?

The weather remains cold and dreary as students and birds alike start to gear up for summer. While most of us have been mildly inconvenienced and slightly outraged at the abnormal weather patterns, changes in weather are a lot tougher on birds.

After a seemingly eternal winter and some late snowfalls, it’s finally looking and feeling a lot more like spring in Northfield. One of the most noticeable harbingers of the new season is the sudden outburst of birdsong around campus.

Although the sluggish spring has been a bit disappointing, life in the Arb continues more or less as usual. The time for frogs and toads to end their winter hibernation is approaching, and as ice and snow recede and temperatures rise, they will flock to breeding sites and begin chorusing and mating.

If you’re in the Arb this spring, particularly in the floodplain or near the banks of the Cannon River, there is a slim chance that you will see a Wood Turtle, also known by its Latin name Clemmys insculpta, a threatened species found in Minnesota. This rare turtle has been hibernating all winter long and will reduce its metabolic rate again at the peak of summer’s heat, so spring is an ideal time to spot one.

The Tree Removal grant project in the Arboretum is already well underway. Three of four sites have already been cleared of non-native trees and invasive brush.
