Arkansas Forest Insects
Tree insect problems can range from a nuisance concern to an epidemic outbreak. They can occur in remote natural woodlands, forest plantations, in a park, or in someone's backyard. The University of Arkansas System Division of Agriculture has Extension foresters and pest specialists dedicated to helping to identify insects, assess problems, and provide potential solutions to limit insect damage to trees.

They are important environmentally for water quality, carbon sequestration, and other values. There are two primary pines in Arkansas: Loblolly and shortleaf pine (Pinus teada and Pinus enchinata).

Hickories, Maples, and Other Hardwood Tree Insects
There are many hardwood species in Arkansas' forests. Hickories, maples, dogwoods, elms, and many others increase species diversity in the forestlands across the State. These species contribute to aesthetic, environmental, wildlife, and recreational values, along with some timber value. There are many species that are not specific to one species and will attack trees across species types.
