In spite of significant progress toward the application of recycling and other waste minimization processes, active landfills are expected to remain a common feature on the landscape for the foreseeable future. The availability of food and habitat at landfills will continue to act as a catalyst for a variety of human-wildlife conflicts. In this paper, we will focus specifically on on-site and off-site conflicts and management alternatives to resolve conflicts associated with gulls at landfills. Case histories of gull damage management programs conducted by Wildlife Services will be presented to illustrate the effectiveness of control strategies adapted to meet site-specific management objectives at landfills in the northeastern United States.
