An aerial survey using false-color infrared film at scales of l :9,600 and l : 12,000 located 93.7% of the oak wilt infection centers ii:1 the 1,500-acre study area. The ground survey of the same area also located 93.7% of the infection centers but half of those found by this method were difficult to relocate because they were not correctly mapped. Whereas aerial survey usually missed only trees of small diameter, the ground survey missed trees as large as eight inches in diameter.
