Woodpeckers have been seen across the region chipping away at the bark of young bur oak. They are drilling into the bark in search of these small larvae of the gall wasp Callirhytis flavipes. During the winter the small, white larvae are found within the inner bark of the branches and twigs of mature oak trees and the trunks of young trees.

While eastern redcedar (Juniperus virginiana) is native to South Dakota, and has many positive qualities, it has become a problem species over large areas of the Great Plains. Even so, eastern redcedar remains one of the more important windbreak species, and is still widely planted. Several cultivars of this species are also popular ornamentals. The cones are eaten by a number of wildlife species (cedar waxwings, pheasants, turkeys, rabbits, and others), and it provides dense cover for a number of others.
The first bright yellow blooms are a welcome change from a long, drab winter. Early spring flowering shrubs have a special place in our landscapes as they are the heralds of the warm weather yet to come.

Bark stripping is commonly seen at this time of the year on a wide range of trees species. Usually the culprit is not seen so tree owners are at a loss as to who is responsible for this damage.
