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.

Biting Minnesota winds and below-freezing days are not always the most pleasant, but puffy jackets, mittens, scarves and hats keep the cold at bay. However, while we humans are able to bundle up or stay indoors to take advantage of central heating, most other species are not so lucky during the winter months.

While it is tempting to think that all animals have the good sense to curl up and sleep through Minnesota’s harsh winters, there are a number of hardy residents that brave the cold and inhabit the Arb year round.

Believe it or not, the Arb does not run itself. There is in fact an Arboretum Office, and many hard-working individuals dedicated to its maintenance.

Fall weather has settled in and temperatures are cooling off--but what would it be like if average temperatures were freezing all year?

It’s nearing the end of October, the leaves are falling, and temperatures are dropping. That means many animals are spending a final few days in the sun and getting ready for hibernation. Snakes are no exception.

What do leaves have to do with the seasons? Most people mark the coming of winter by the time that trees become bare and leaves litter the ground. The trees themselves, however, begin their winter preparations long before we humans do.
