Gone is another month in Cordova, Alaska. We finished our nest island monitoring and spent the large majority of the month performing maintenance on islands that were below project-developed standards. Ideally, the islands possess at least 30% aerial cover provided by the sweet gale shrub. If they lack the desired proportion of sweet gale, we add shrubs until the desired level is achieved. To do this, crew members search for ideal shrubs nearby and transplant these shrubs to the island.

Island anchors sometimes become tangled or loose, usually resulting in a rotating, drifting, or misplaced nest island. These
