ABSTRACT: Reported frontcountry bear incidents and property damage have been reduced over 80% since implementation of the Human/Bear Management Plan in 1975. The backcountry, which represents 90% of the Park, has not experienced a decline in human/bear conflicts. Data suggest that backcountry users alone suffered an estimated 2800 bear incidents costing $56,250 during 1979. Alterations in bear behavior due to human food availability and the high number of bear/human interactions still continues to occur, thus perpetuating the problem and maintaining a high potential for bear-caused human injury, and mortality. Six steps are identified that, when added to the present program, will eliminate the availability of human food to bears and consequently reduce bear/human interactions and the potential for human injury. Five years following full implementation of this program it is anticipated that bear incidents will be reduced to an extremely low level, personal injuries caused by bears will be eliminated and the bear population will be returning to a more natural state.
