Reference layers on tablet PC include: Survey boundary area USGS 7.5 minute quads (1:24,000) Any previously mapped infestations or survey routes Digital Area Sketch Mapping using a Hammerhead tablet PC (Baker GeoLink software) and Bluetooth enabled Garmin EMTAC GPS lined to software
Conduct surveys early to middle winter (leaf-off) Map female seed-bearing trees Winter surveys allow fast surveys and low cost/acre Winter : mapped 163,256 acres in 6 days Cost to WNF = $4.66/ac
Conduct survey in early to middle winter (leaf-off) Altitude of feet above ground level at speeds of 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
-79,734 ac surveyed -1,356 infestations identified -6,399 ac of Ailanthus mapped
Objective: Search, Inventory, and Treat Ailanthus BEFORE any active management Ground truth portion or aerial mapped polygons Look for Ailanthus wilt Determine a strategy to treat Ailanthus prior to implementing Landscape Vegetation Projects implementation
Learn how to identify Ailanthus wilt Help ground truth aerially mapped Ailanthus on WNF when in the field
