Service Description:

Readily available data were aggregated within 4 square kilometer hexagons to investigate the level of protection relative to wild coast attributes. 

Spatial data were compiled and ranked by quintiles for four attributes: 

  1. Physical Intactness using a landscape development intensity index from (Heady et al. 2018), Coastal Armoring, and Coastal Structures (both from the California Ocean Protection Council), 
  2. Ecological Intactness using Natural Landscape Blocks (connectivity; California Department of Fish and Wildlife Areas of Conservation Emphasis II), Count of marine mammal haul outs and seabird colonies (California Department of Fish and Wildlife Biogeographic Information and Observation System, National Oceanic and Atmospheric Administration, California Natural Diversity Database, and The Nature Conservancy), 
  3. Biodiversity using a rarity weighted richness index of habitat and species richness, weighted by rarity and coastal endemism from (Heady et al. 2018), and 
  4. Human Disturbance using Microsoft’s ration of building area, Esri’s ratio of total road length, and California Coastal Commission’s count of coastal access points. 

Each attribute was ranked in quintiles with 1 representing the lowest scoring fifth and 5 representing the highest scoring quintile and then combined using an additive model which was then in turn ranked in quintiles to represent the wildness of each hexagon along the coast. Wild Coast quintiles also ranked from 1 the lowest scoring to 5 the highest scoring or wildest score possible. Wild coast index scores of 4 and 5 represent wild coast qualities in this study. Conservation management status modified from (Heady et al. 2018) and Marine Protected Area data from the California Department of Fish and Wildlife and the National Oceanic and Atmospheric Administration were then overlaid with wild coast quintile scores to investigate the levels of terrestrial and marine protection of hexagons with different wild coast scores.
