Censusing and Collecting Marsh Raccoons via an Air-Boat

An air-boat was used successfully to collect raccoons in a tidal marsh. Three hundred and four raccoons were seen and collected for 68 man hours expended with the air-boat as compared to 62 raccoons seen and collected for 56 man hours expended with the John·boat. During one two-hour collection, 39 raccoons (approximately one every three minutes) were collected with the air-boat. The number of raccoons seen and collected on each tide was closely correlated to tide height.
