Abstract
Urban Norway rats (Rattus norvegicus) and black rats (R. rattus) can have diverse and significant negative impacts on urban landscapes and residents. A variety of different approaches have been developed for measuring rat populations to support management efforts. However, the utility of these approaches has been limited, as they account for the magnitude but not the consequences of infestations and thus may not reflect the harm that cities are ultimately seeking to mitigate. We propose an alternative approach through the development of a rat risk index, which would add novel measures of rat-related impacts to existing measures of rat abundance. Such an index would be particularly useful for goal setting, program evaluation, and prioritization in the context of municipal rat management programs.
期刊介绍：
The Journal of Wildlife Management publishes manuscripts containing information from original research that contributes to basic wildlife science. Suitable topics include investigations into the biology and ecology of wildlife and their habitats that has direct or indirect implications for wildlife management and conservation. This includes basic information on wildlife habitat use, reproduction, genetics, demographics, viability, predator-prey relationships, space-use, movements, behavior, and physiology; but within the context of contemporary management and conservation issues such that the knowledge may ultimately be useful to wildlife practitioners. Also considered are theoretical and conceptual aspects of wildlife science, including development of new approaches to quantitative analyses, modeling of wildlife populations and habitats, and other topics that are germane to advancing wildlife science. Limited reviews or meta analyses will be considered if they provide a meaningful new synthesis or perspective on an appropriate subject. Direct evaluation of management practices or policies should be sent to the Wildlife Society Bulletin, as should papers reporting new tools or techniques. However, papers that report new tools or techniques, or effects of management practices, within the context of a broader study investigating basic wildlife biology and ecology will be considered by The Journal of Wildlife Management. Book reviews of relevant topics in basic wildlife research and biology.
