Capparis sandwichiana is endemic to the Hawaiian Islands. There are many occurrences still surviving on the islands of Kauai, Kaho`olawe, O`ahu, Ni`ihau, Moloka`i, Maui, Lana`i, and Hawai`i. This species is also found on the Northwestern Hawaiian islands of Midway Atoll, Pearl and Hermes Atoll, and Laysan. The total population number is still in the thousands, however, a decline of at least 10% over the last ten years has been estimated. C. sandwichiana has been adversely affected by the many factors threatening most of the Hawaiian coastal and lowland plant taxa.
