When you get a call from a client or encounter a wildlife problem, there are several things you would like to know before deciding on the next step. The following assessment will help you think through many wildlife conflicts and lead to successfully resolving the issue.
- The Problem– The first thing to determine is whether the problem is real or perceived by the landowner. Seeing a coyote or raccoon walk through a backyard is not a concern. However, this situation may be unsettling for someone who is frightened, especially if there are children or pets in the home. Determine if the problem can be handled with education or if some on-site response is warranted.
- Species Identification– Many people have very poor wildlife identification skills. You cannot resolve a problem unless you know exactly which species is involved. For example, many homeowners often cannot distinguish between moles and voles. Both species may damage lawns or planting beds and appear similar, but the approach to solving a problem would be quite different. Ask questions until you feel comfortable with the species identification. Request that the person send you a quality photograph of the animal if possible.
- Short- vs. Long-Term Problems– One needs to understand wildlife behavioral ecology to determine what solutions might be suitable. For example, problems with migratory geese grazing on crops may only last for a couple of weeks during spring or fall. In this case, flagging, predator models, or other short-term visual deterrents could be effective. However, with resident Canada geese, problems may occur during the entire year. Scare devices usually have limited effectiveness for local-nesting geese. It is essential to understand the seasonal aspects of wildlife behavior to develop effective solutions. Exclusion or animal removal may be needed to resolve long-term conflicts.

- Unique Species Attributes– Again, knowing animal behavior is critical. For example, resident Canada geese molt (replace) their flight feathers during late June each summer and these birds are flightless for about 3 weeks. It is easy to round-up and catch an entire flock by hand with volunteers, canoes, and nets (with the appropriate federal and state permits see Laws Concerning Wildlife). This is a critical time for goose management and research each year. Species such as ring-billed gulls are sensitive to parallel wires, and wires may be used to deter them from nesting areas or rooftops. However, European starlings will completely ignore parallel wires and fly through them.
- Potential Costs– The cost-benefit of control alternatives may vary substantially. Low-cost methods seldom work or may provide limited short-term control. At the other extreme, exclusion is usually very expensive up-front, but may provide effective control of wildlife problems for many years. It is important to determine cost-effective solutions that will provide long-term resolution of wildlife concerns.
- Tolerances– You need to determine a person’s tolerance for a specific wildlife problem, and what level of control would be acceptable. One animal in or near a home may be unacceptable. People’s core values and beliefs do not change easily, so education may be limited. Sometimes the solutions that people desire are simply not realistic or cost-effective.
