Many rodent species are effective burrowers. In North America, these include species of ground squirrels, prairie dogs, marmots, and pocket gophers. The burrow systems of other species of rodents such as voles and mice are less elaborate and pose less potential for direct damage. Burrowing abilities, coupled with other characteristics (e.g., prolific, adaptable, ever-growing incisors for gnawing), can result in many types and amounts of impacts to human resources and ecosystems. Damage occurs to levees, roadbeds, buried pipes and cables, intrusion to sensitive areas (such as military sites, capped hazardous waste burial sites), vegetation effects, effects on water infiltration/runoff, and …

Rodent populations at airports can cause human safety issues by attracting raptors which increases the risk of raptor-aircraft strikes. Various methods can be used to reduce rodent numbers, including trapping, poisoning, and habitat manipulation. Burrow disruption by turf rolling and soil aeration is a potential habitat manipulation method that could potentially reduce the carrying capacity for rodents. We tested this method at Kansas City International Airport, Missouri. We monitored the rodent populations in a control (untreated) area and in a nearby treated area where the turf was rolled and the soil aerated. We used grids of live traps to determine …

The New York State Department of Environmental Conservation initiated a Double-crested Cormorant (Phalacrocorax auritus) control program in the eastern basin of Lake Ontario to mitigate cormorant impacts in 1999. Key objectives included improving the quality of Smallmouth Bass (Micropterus dolomieu) and other fisheries, restoring the structure and function of the warmwater fish community and reducing cormorant impacts to nesting habitats of other colonial waterbird species. In eight years of intensive control, cormorant numbers declined, with a corresponding reduction in estimated fish consumption. Diversity and numbers of co-occurring waterbirds either increased or have not been shown to …
