ManagementThe refuge provides a sanctuary, but refuge staff must conduct multiple management activities to maintain and enhance wildlife habitat. The year-long growing season requires an almost constant battle to control aquatic and adjacent upland vegetation using mowing, disking, and prescribed fire. Without control, cattail and bulrush would dominate wetlands, leaving them unsuitable for use by endangered and migratory wetland birds. Water level manipulations also allow refuge staff to control the amount and location of mudflats, shallow and open water, and dry bare ground for foraging and nesting endangered Hawaiian waterbirds. During the nesting season, extensive efforts to control predators are conducted to help young chicks survive to flight stage. |
