This FAA Advisory Circular (AC 150/5200-33C), issued February 21, 2020, provides guidance on land uses and development projects near public-use airports that may attract hazardous wildlife such as birds, mammals, and reptiles, which pose serious safety and economic risks to aircraft. It outlines recommended practices for airport operators, land-use planners, and federally funded airport projects to assess and mitigate wildlife hazards, though compliance is voluntary except for airports holding operating certificates under 14 CFR Part 139 or receiving federal grant funding. The document updates and replaces the previous 2007 version of the same circular.

This Puget Sound Energy brochure explains the company's vegetation management program, which focuses on trimming or removing trees near power lines to prevent outages and maintain reliable electrical service across Washington state. It outlines methods such as selective tree removal and directional pruning, and advises homeowners to avoid planting large trees beneath power lines or near electrical equipment. Residents are encouraged to call 811 before digging and to choose smaller native or ornamental trees suitable for planting near utility infrastructure.

This 1997 FAA Advisory Circular provides guidance on identifying and managing land uses near public airports that attract hazardous wildlife, such as waste disposal sites, wastewater treatment facilities, and wetlands. It recommends minimum separation distances — 5,000 feet for piston-powered aircraft airports and 10,000 feet for turbine-powered aircraft airports — between wildlife attractants and aircraft movement areas. The document notes that gulls, waterfowl, and raptors are among the most common wildlife involved in damaging aircraft strikes, and urges airport operators, land use planners, and developers to avoid practices that increase wildlife hazards near airports.
