Table 2. Description of categories for reef slope and rugosity (habitat complexity), estimated visually for each underwater visual census (UVC) transect.

Category	Description of reef slope & rugosity categories
1	Reef slope 0–10°. Expanses of rubble and sand with some small scattered bommies
2	Reef slope <45°. Bommies dispersed amongst mostly rubble and sand
3	Reef slope ∼45°. Small rubble and sand patches amongst bommies and/or coral structure
4	Reef slope >45°. Complex coral structure, bommies, some small over-hangs, holes and caves
5	Reef slope ∼90°. High reef complexity, large over-hangs, holes, caves and bommies
