    • Coral Favorability: Managed Conditions - American Samoa

    Metadata Updated: December 27, 2024

    Managers have some ability to support healthy environmental conditions through strategic action at a local and regional scale, such as water quality. This layer synthesized spatial information for several managed conditions to create a relative score for how favorable a given location is for coral growth and survival.

    Environmental conditions contributing to this layer included: chlorophyll-a concentration, fish and herbivore biomass, turbidity (Kd490), and macroalgal cover. Covariation in these conditions was accounted for using principal component analysis (PCA) to form composite variables of conditions that have strong relationships with one another. The resulting principal components were averaged and scaled from 0 (worst) to 1 (best) to produce a coral favorability score for managed conditions. These data are provided as a raster with a resolution of 500 m for American Samoa, including Tutuila and the Manua Islands (Ofu, Olosega, and Tau).
