Other nest sites for Sternula albifrons sinensis may be present on King Island, given their capacity to nest as isolated pairs. These sites may be relatively difficult to locate without dedicated surveys (Woehler 2009). Habitat critical to the survival of the species Habitat critical to the survival of Sternula albifrons sinensis on King Island includes all known nesting sites. Reservation Status Sternula albifrons sinensis is reserved within Christmas Island Nature Reserve and Lavinia State Reserve. Table 13.

Threats and Management Threats to Sternula albifrons sinensis on King Island include: disturbance and destruction of nests and nesting habitat through recreational use of nesting beaches; disturbance and destruction of nests and nesting habitat through coastal development; predation of eggs, chicks and adults by introduced rats, cats and dogs. Threats to Sternula albifrons sinensis on King Island are similar to threats on mainland Tasmania and elsewhere in Australia, and centre around threats to beach nesting-sites (Woehler 2009). A rapid increase in 4WD and quad-bike traffic on beaches during summer months can destroy nests and eggs and crush chicks, dogs off-leash can predate on eggs and chicks, and recreational activities on King Island beaches can lead to disturbance to nesting and feeding shorebirds and terns (Woehler 2009). All disturbance events to migratory shorebirds reduce their capacity to store food for their migration, resulting in leaner birds with lower body masses unlikely to migrate successfully. To reduce human impacts to shorebirds and small terns will require innovative and concerted efforts by the King Island community through changes in lifestyle and traditional coastal activities. Recovery Actions specific to King Island Provide information and extension support to the King Island Natural Resource Management committee, King Island council, Government agencies and the local community on the location, significance and management of known breeding sites; Utilising existing knowledge, determine priority shorebird habitat and breeding sites for management; Install temporary/seasonal structures to prevent damage to these priority shorebird habitat and breeding sites; King Island Biodiversity Management Plan 174

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
