Adelie penguin occupancy survey of the Robinson Group, 2006

An occupancy survey in November 2006 found a total of 29 islands in the Robinson Group of islands had populations of breeding Adelie penguins. The boundaries of breeding colonies at 27 of these islands with larger populations were subsequently mapped for abundance surveys by circumnavigating the perimeter of sub-colonies on foot while carrying a Garmin GPS (Legend Cx or Vista C) to log the track taken. The person walking around the sub-colonies maintained a buffer distance of 2-5m between themselves and the penguins at the sub-colony boundary. This buffer distance was reduced to between 1 and 4m in the final shapefiles.
