BMPs are a series of free handbooks developed by wildlife management professionals, veterinarians, researchers, and trappers that describe the most safe, effective, selective, practical and humane methods and techniques for capturing furbearer species in the United States.

Wildlife biologists, veterinarians, experienced trappers, and statisticians work together to design studies and analyze data in order to determine BMPs. The BMP evaluation criteria covers animal welfare, selectivity, practicality, efficiency, and safety of the trapping methods. 

BMPs provide science-based recommendations to trappers and managers on the best available traps and methods for capturing each furbearer species. This information assists in the management and protection of wildlife populations and their habitats.
