Existing Conservation Measures Surveys of the Seal River, Grassy River, Yarra Creek, Pegarah State Forest and Naracoopa areas were undertaken by TSS personnel in 2007 and 2009 as part of flora verification projects funded by the Cradle Coast Authority (Wapstra et al. 2009). The surveys revealed the presence of large subpopulations near Naracoopa and along the Seal River, the latter mostly within an area proposed to become a Conservation Area. The response of the species to fire has been monitored by personnel with DPIPWE’s Private Land Conservation Program (Reekara Road subpopulation). The results indicate that the species is likely to be an obligate seeder. Distribution and Habitat On mainland Australia Pimelea axiflora subsp. axiflora occurs in Victoria and New South Wales (Entwisle 1996). In Tasmania the species is restricted to King Island (Figure 4), where it grows as an understorey shrub in wet eucalypt forest and in damp environments along watercourses. Eucalyptus globulus , Eucalyptus viminalis or Eucalyptus brookeriana may be the dominant eucalypt, overtopping a relatively open small tree/tall shrub layer of Pomaderris apetala , Acacia melanoxylon and Melaleuca ericifolia . Smaller shrubs include Bursaria spinosa and Pimelea drupacea , while the ground layer is typically species poor, with Australina pusilla subsp. pusilla, Clematis aristata , Ehrharta stipoides and Pteris tremula, and in less mesic conditions Pteridium esculentum . The altitude range of known sites is 30 to 120 m above sea level and the underlying geology is mostly Precambrian sandstones/siltstones, but also includes Quaternary sediments and Devonian granite. Within Tasmania the species has a linear range of about 35 km, an extent of occurrence of 260 km 2 , and an area of occupancy of about 6 to 7 ha. Populations Pimelea axiflora subsp . axiflora is known from twelve subpopulations on King Island (Table 4). Mature plant numbers are available for six of the subpopulations, with about 2000 plants in total. The earliest King Island collection of Pimelea axiflora subsp . axiflora held by the Tasmanian Herbarium is from 1966. Several of the known subpopulations were uncovered during Bushcare surveys of private land in 1998, and it is considered likely that additional stands will be discovered given a concerted survey effort. Habitat critical to the survival of the species Habitat critical to the survival of Pimelea axiflora subsp . axiflora on King Island includes known sites and their immediate catchments. Reservation Status Pimelea axiflora subsp . axiflora is not known from any formal reserve in Tasmania. One subpopulation on King Island occurs within a ‘river reserve’ that has been recommended to become a Conservation Area under the Tasmanian Nature Conservation Act 2002 (CLAC Project Team 2005a), while another occurs on private property that is covered by a conservation covenant under the same Act (Table 4).

    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.
