this species on the island (Donaghey 2003). One suggestion is that this species did not recover after a drought at the end of the 1980s, and that this may have been linked to the associated structural changes to dams resulting from concentrated cattle use at the time of the drought. However, single surveys are by no means adequate to confirm the absence of this species at a site, and continued intermittent surveys across King Island are planned. Limnodynastes peronii was, by contrast, heard calling in abundance at the majority of sites surveyed in November 2009. The November 2009 surveys also sampled tadpoles for chytrid fungus at three sites: the Currie sewage ponds, Nook Swamps in Lavinia State Reserve and Little Cask Lake near Lake Flannigan (one of the historic sites for Litoria raniformis ). The first two of these tested positive for chytrid fungus, while Little Cask Lake was negative. That Limnodynastes peronii was found at the sewage ponds despite the presence of chytrid may suggest that the species has some resistance to the disease. King Island Biodiversity Management Plan 163

All known subpopulations of Litoria raniformis on King Island , and any new subpopulations found, are considered important for the survival of the species. Habitat critical to the survival of the species All permanent freshwater waterbodies such as natural lagoons, wetlands and swamps on King Island are potential habitat for Litoria raniformis . Artificial ponds and farm dams on the island are also potential habitat, particularly where there is submerged and/or emergent vegetation. Any locations where Litoria raniformis is found on King Island is considered to be habitat critical to the survival of the species. Reservation Status On King Island, Litoria raniformis is reserved within Lavinia State Reserve. King Island Biodiversity Management Plan 164

Drainage and clearance of wetlands is the major threat to Litoria raniformis on King Island. Greater protection for wetlands through voluntary agreements including covenants and management agreements are important in preventing the loss of natural lagoons that form the bulk of suitable breeding sites. Stocking of sheep and cattle in and around wetlands is a serious threat to the integrity of habitat, as well as posing a direct threat to the species from trampling. Fencing off natural wetlands to exclude stock is important, as is the provision of alternative stock watering sites.

    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.
