very small population size; genetically isolated subpopulations; loss of genetic diversity; clearance of potential habitat; degradation of potential habitat, particularly by fire; predation by cats and black rats. Substantial areas of King Island have been cleared for agricultural purposes and artificially drained since European settlement, primarily for the production of dairy cattle. The net result has been the loss and fragmentation of suitable habitat for Acanthiza pusilla archibaldi. The vulnerability of the species to wildfire is highlighted by the loss through fire of over 90% of forest and scrub at Nook Swamps in early 2007 (RMCD 2007). Prior to the 2007 fire, Nook Swamps was the largest remaining area of swamp forest on King Island. The 2007 fire has resulted in the long-term, and in some areas, permanent loss of mature swamp forest at Nook Swamps (RMCD 2007). It has been suggested that the surviving population of Acanthiza pusilla archibaldi may be threatened by competition with the Tasmanian Thornbill Acanthiza ewingii rufifrons (Garnett & Crowley 2000). Ticks have also been suggested as a possible threat to Acanthiza pusilla archibaldi (Garnett & Crowley 2000), although there is no direct evidence for this. 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 populations and areas of potential habitat (Actions 27.1-3, 27.5, 27.6, 28, 29.1); Design, plan and implement measures to reliably confirm Acanthiza pusilla archibaldi is extant on King Island (Action 20.1). Design of surveys to confirm species is extant to include, but not necessarily to be limited to, the following elements; (a) define and map all remaining patches of suitable habitat for the species on King Island, and any other adjacent islands on which the species has the potential to occur (Hunter Island, Three Hummock Island); (b) conduct surveys of all areas of habitat, surveys to be conducted by professional and experienced observers within one year of the start of the Plan; (c) employ a minimum of two sightings as evidence that species is extant.

    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.
