Enhance seabird-nesting habitat through removal of ironwood, beggar’s tick, and sandbur. Install artificial burrows. Survey and remove other invasive incipient weeds.
Perform habitat restoration activities. Survey and remove highly invasive incipient weed species.
Protect public safety due to the island being a dangerous landing location.
