CRAMP Rapid Assessment. Site Selection Process

Twenty-two RAT sites were added to the 32 CRAMP sites for a total of fifty-four sites, on all eight main Hawaiian Islands: Hawai’i, Maui, Kaho’olawe, Lāna‘i, Moloka’i, O’ahu, Kaua‘i and Ni‘ihau were sampled.

Main Hawaiian Islands assessment sites n=54. Two additional CRAMP sites not shown were recently added: Mahainahina, Maui, and Ala Wai, O’ahu.

Location of each assessment site was determined using habitat maps. A diverse spectrum of environmental conditions was selected to provide accurate representation of the main islands in the State of Hawai’i. The following criteria were used in the site selection process:

  • A range along a gradient of anthropogenic impact from heavily impacted sites to sites with limited human activity;

  • Sites with specific impacts including fishing, sedimentation, nutrification and introduced species ;

  • Naturally occurring conditions as close to original as possible;

  • Sites that encompass the entire scope of wave exposure and direction;

  • Sites that provide a wide range in human population;

  • A range of legal protection including sites with various levels of marine protection and open access;

  • Wide spatial gradients to encompass longitudinal differences;

  • Accessibility.
