Unit

Conduct survey in early to middle winter (leaf-off)

Altitude of 150-600 feet above ground level at speeds of 55-80 mph

Survey lines spaced at 1,800 – 2,500 feet apart on a N-S orientation (based on visibility and environmental conditions)

When groups of Ailanthus spotted, pilot generally circles back around infested areas to facilitate mapping
