Adelie penguin occupancy survey of Bechervaise Island, 2013

All subcolonies on Bechervaise Island were mapped with a hand held GPS (Garmin Legend) on the 9th of January 2013). The mapping was undertaken by Julie McInnes and Helen Achurch. The colonies were mapped at a constant 2m buffer. If subcolonies were less than 2m apart they were mapped in the same outline, colonies greater than 2m apart were mapped separately. The final layer has a 2m buffer around the colony included in the layer.
