Getting to the Point: Accuracy of Point Count in Monitoring Ecosystem Change

Figure 1

Comparison between ground-truth (a) and simulated (b) estimates of mean percent cover (±SE) using different numbers of points per frame. Ground-truth data are sponge cover estimates from a 20-m long transect video recorded at Rainbow Gardens Reef in 2004. Simulated sponge cover estimates are based on field estimates of 𝜇 (3%) and 𝜎 (0.8).
