Keeping the University of Iowa campus beautiful is a full-time job. Luckily, the UI Landscape Services team gets a little assistance each year in the form of some notoriously busy helpers: the nocturnal, semi-aquatic beaver.
Beavers, a native Iowa species, typically gnaw down trees along the UI campus riverbanks, which is fine for some tree species, but not for others. Instead of stopping the beavers’ behavior, the tree care team decided to work with the beavers’ natural talents. By wrapping valued native and planted trees with protective wire, the invasive and common native species like Boxelder, White Mulberry, Siberian Elm, Willow, Green Ash, and Silver Maple, are left for the beavers to utilize in their underwater homes for food and shelter.
