The second, third and fourth formulae on page 4 under heading “Abalone responses to benthic habitat types” were published with some errors. The correct formulae are given below:

$$ {\text{Proportion of rock covered in ERA}} = {\text{area of ERA}}/{\text{rock area}} $$
$$ {\text{Proportion of rock covered in other habitat types}} = \left( {{\text{rock area}} - {\text{area of ERA}}} \right)/{\text{rock area}} $$
$$ {\text{Expected proportion of abalone on each habitat type}} = {\text{proportion of rock covered in habitat type}} $$
