Rottnest Island plant species’ maps. The presence of these plant species is shown as the shaded areas. Graduated dots indicate the level of presence (by way of the Braun - Blanquet Scale) of each of those species at field inspection points. The text in brackets after each species name indicates where the use of that species was greater than (>) or equal to (=) what would be predicted from its abundance on the island. 5 .
