Table 2. Summary of the labelling approach for benthic components at Ningaloo Reef using class label and percentage cover.

Class label Description Example
Continuous classes If cover > = 90%, the point was considered as ‘pure’; the remainingcover types were omitted and the class name received a prefix“Continuous” Component 1 (most dominant) is limestone pavement with 95% cover, component 2 (second most dominant) is hard coral, with 5%, resulting in the label “Continuous limestone pavement” label and component 2 input omitted
Mixed classes with single dominant category If the dominant type was biotic and cover was between 50–90% andthe difference between the highest and second highest cover> = 30%, the remaining cover types were incorporated into thename. The name was derived from the dominant componentwith the prefix “Dominant” Component 1 is limestone pavement with 70% cover, component 2 is hard coral with 25% cover, resulting in the label “Dominant limestone pavement” label and the second label of hard coral for component 2
Mixed classes with equal cover If the (Cover 1– Cover 2) < = 20% they were considered equal;and each received the prefix “equal” if the sum of the equalpercentages > = 90% Component 1 is limestone pavement with 50% cover, component 2 is hard coral with 45% cover, therefore (Cover1-Cover2< = 20% and component 1 was assigned a label “equal limestone pavement” and component 2 received label “equal hard coral”
Mixed classes that donot fall into the abovecategories Mixed classes that did not fit into the above categories remainedin the order they were in and receive the prefix “1”, “2”, “3”, etc.depending on their percentage value Component 1 is limestone pavement with 60% cover; component 2 is hard coral with 35% cover, component 3 is sand with 5% cover, therefore labels were in that order: “1-limestone pavement”, “2-hard coral” and “3-sand”
