for Problems Affecting Woody Ornamentals and Herbaceous Perennials
This guide provides information on problems commonly associated with woody and herbaceous perennials of the upper Midwest. Detailed information about when and where the problems are observed, signs and symptoms, and treatment methods are included for each problem.
Landscape problems can be caused by living (biotic) or nonliving (abiotic) sources. Biotic pests include insects, mites, fungi, viruses, bacteria, and wildlife. Abiotic problems develop from environmental (temperature, wind, moisture), site (soil, compaction), cultural (pruning, mower blight), chemical (spills), or nutritional (excess or deficiency) problems.

Flowering Ornamental Fruit Trees
Vertebrate pest damage occurs on many woody and herbaceous plants. Most of the time vertebrate pests are not discriminating as to the host they damage.
Damage from beavers, chipmunks, deer/elk, feral hogs, mice, pocket gophers, porcupines, rabbits, raccoons/opossums, thirteen-lined ground squirrels, tree squirrels, voles, woodchucks, woodpeckers, and other birds are included in the vertebrate pest pages.
