Management Goals and Objectives:
Moku Manu Islet has the most diverse and one of the densest seabird colonies in the Main Hawaiian Islands. Survey Wedge-Tailed Shearwater chicks annually and conduct surveys of other seabird species. Prevent disturbance to seabirds, including prevent destruction of seabird burrows.
Prevent introduction of invasive species. Survey and remove highly incipient weeds.
Prevent destruction of sensitive vegetation. Soil is sensitive to erosion. Mostly native plants are found on the islet.
Prevent disturbance of monk seal and turtle. Monk seals frequently haul out on the islet.
Eliminate shore-based fishing and collection from the inter-tidal area.
Protect public safety due to the island being a dangerous landing location.
