Summary

Data collected from 35 dense Acropora patches. When full transects could not be made, quadrat data was collected. Photo/video footage was collected from every patch.

Parameters

Transect data of ACER patches: % live Acropora, % dead Acropora, % diesease/recent dead Acropora, % Acropora rubble, # of live Acropora fragments, Prevalence of Acropora disease, fireowrm predation, damselfish gardens, All other coral species (>4cm) identified and measured

Method

Transect monitoring - This study acquired population and condition data in the densest location of all thirty-five dense patches. At each site we conducted four non-overlapping 30 m transects where allowable by patch size. Where patches did not accommodate the full transect length (Sites 16, 18, 23, and 29), the transects were cut short and the number of assessed quadrats was noted. In a 1 m² quadrat placed at meter intervals along each transect we estimated % live Acropora, % dead Acropora, % disease/recent dead Acropora, % Acropora rubble, number of live Acropora fragments, prevalence of Acropora disease, fireworm predation, and damselfish gardens (Figure 3). Care was taken not to double count incidences of disease, fireworm predation, and damselfish gardens between quadrats. All other stony coral species >4 cm diameter were identified and measured. In the rare occasion that the transects had an extreme density of small Porites astreoides colonies, only three transects were assessed for other stony corals. Qualitative video footage and photographs were collected.
