The company is seeking an incidental take permit from the U.S. Fish and Wildlife Service and has prepared a draft habitat conservation plan and environmental assessment to minimize the effects on the endangered Hawaiian petrel ('ua'u), the endangered Hawaiian stilt (ae'o), the endangered Hawaiian hoary bat ('ope'ape'a), and the threatened Newell's shearwater ('a'o). Six of the seven 165-foot towers already have been built on land owned by Castle & Cooke. The company plans to build the remaining tower and operate all seven for a period of up to two years to collect data on wind patterns, according to permit documents.

The Kaheawa Wind Power wind farm on Maui will perform $3.8 million in work to benefit birds and bats to make up for any damage the species suffer from the rotating blades of 20 wind turbines.
