Lago on Reserve Coast 5 Manresa Lagoon Private Cradle Coast Pearshape Unknown Threats and Management Threats to Botaurus poiciloptilus on King Island include: destruction of wetland habitat; decline in water quality due to increased salinity, siltation and pollution; overgrazing of wetland habitat by livestock; frequent or intense burning of wetland habitat; predation of eggs and chicks by introduced cats. The major threat to the Australasian Bittern across its range is the destruction of its wetland habitat, primarily through diversion of water for irrigation and drainage of swamps for agriculture (Marchant & Higgins 1990, Garnett & Crowley 2000). Because of its comparatively specialised habitat requirements (i.e. densely vegetated wetlands), the Australian Bittern may be more sensitive to habitat loss than many other wetland birds (Garnett & Crowley 2000). Widespread degradation of the swamp habitat for the Australasian Bittern across its range has also occurred through a decline in water quality due to increased salinity, siltation and pollution. Pollution in wetlands is likely to cause a decline in many of the species' prey species, such as eels, freshwater crayfish and frogs which in turn may have a negative effect on Australasian Bittern population health and numbers (Marchant & Higgins 1990). Overgrazing by livestock and the frequent or intense burning of wetland areas reduces the dense vegetation that forms the core habitat of the Australasian Bittern (Garnett & Crowley 2000). King Island was characterised by many swampy habitats prior to European settlement, and the number and condition of these has declined significantly over the last century (Donaghey 2003). Across its range, the Australasian Bittern is subject to the predation of eggs and juveniles by European foxes and feral cats (Garnett & Crowley 2000), and the large number of feral cats on King Island may pose a significant threat to the species. The recent introduction of the European fox to Tasmania represents a novel threat to the species on the mainland of Tasmania, and the introduction of the fox to King Island would have a devastating effect on the Australasian Bittern. 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 habitat; Protect Nook Swamps from wildfire; Utilise existing knowledge to determine priority sites for management; Develop and implement a community education program for the management of swamp and wetland habitat on the island.

Haliaeetus leucogaster (White-bellied Sea Eagle) Description Haliaeetus leucogaster is a large and powerful bird of prey with long broad wings and a short wedge-shaped tail (Plate 11). Adult birds are predominantly white and grey. The head, breast and belly, and the feathering on the legs, are white. The back and upper surfaces of the wings are grey, although the wings have black tips. The undersides of the wings are greyish-black around the distal

    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.
