What is the minimum altitude to fly over a National Wildlife Refuge?

The minimum altitude to fly over a National Wildlife Refuge is 2000 feet Above Ground Level (AGL). This altitude is specified to help minimize disturbance to wildlife, particularly during sensitive periods such as nesting and migration. Flying at this height allows pilots to safely observe the grounds while mitigating the risk of causing stress or disruption to the animals inhabiting these protected areas.

When flying over sensitive ecosystems such as a National Wildlife Refuge, it's essential to prioritize environmental stewardship while complying with regulations designed to protect wildlife. The 2000 AGL altitude serves as a standard guideline in aviation to balance human activity and conservation efforts.

The other altitudes listed—1000, 1500, and 2500 AGL—do not meet the established requirements for safely flying over these designated areas without potentially interfering with wildlife.
