Anthropogenic stress scores.

Four measures of local stress at each site: sedimentation, nutrients, human population and fishing pressure used to calculate our cumulative “Stress Index” (sources in supplemental information). A comparison with the Halpern et al. (2008) [15] and Healthy Reefs [16] indices is also shown, though note that only the relative rankings are comparable. Sapodilla and Utila experience higher local impacts and lower reef health. *Note that while low Stress Index and Halpern Index scores indicate fewer local stressors, a low Healthy Reefs Index score indicates worse reef health.
