11. Map the location and extent of priority flora and species vulnerable to frequent fire or fire exclusion for long periods. 12. Research the susceptibility to dieback disease, response to fire, reproductive biology, taxonomy and age to maturity of all priority plant species. 13. Determine the factors governing the distribution of key and priority species. 14. Research the susceptibility of plant species to plant pathogens in areas of coastal dune systems and assess the possible ecological impact of changes in plant communities. 8.0 FAUNA BACKGROUND Walpole-Nornalup National Park has considerable value for fauna conservation due to its relatively pristine state, its continuity with surrounding uncleared lands that provide a wide range of habitats and corridors for migration, and its diverse landforms and high rainfall. The distribution of animal communities is broadly linked to the Park's landform systems rather than plant communities (see Section 4.0 Geology, Soils and Landforms ). The mammal fauna of the south coast has declined considerably since European settlement (How et al., 1987). This decline has been attributed to clearing, changing fire regimes, and introduced pests and diseases. Nevertheless, it is believed that few species have become extinct since settlement. Nineteen species of native mammal are found in the Park, including the Southern Brown Bandicoot which is gazetted as threatened. In addition, two gazetted threatened species - the Chuditch and Western Ringtail Possum - may occur in the Park. The Park also has populations of Honey and Pygmy Possums, Quokkas and Brush-tailed Phascogales which are all uncommon. One hundred and nine species of birds are found in Walpole-Nornalup National Park, including five species that are gazetted as threatened. This relatively high number of species is attributed to the wide range of habitats found in the Park. Twenty-two species of reptiles, including three restricted to the southern dunes, occur in the area (Wardell-Johnson, data, species lodged at WA Museum). The reptile fauna of the Park is low compared to similar sized areas in the and zone. This is attributed to the relatively even distribution 30
of rainfall and cloud cover, and rapid temperature changes in summer. The greatest number of reptiles are found in the coastal dunes followed by swamps and flats where fallen and dead vegetation provides a complexity of refuges. The Park is also one of the richest areas for frogs in Western Australia. All 12 species found in the Park are endemic to the south-west. One species (Geocrinia lutea) is found only within a radius of 12 km of Walpole (Roberts et al., 1990). Swamps and drainage lines support the greatest number of species. Little is known of the invertebrates of the Park, but what is known indicates that pockets of these animals have survived from 65 million years ago when Australia was part of the super continent Gondwana. The climate in that era was warm and moist, with little seasonal variation. The relatively non-seasonal climate of the Walpole area and the persistence of the red tingle tree, which provides a moist, protected habitat, have allowed these Gondwanan relicts to survive in this area. Related species survive in the rainforests of Tasmania, eastern Australia, New Zealand, Chile and Madagascar. Relict species of spiders include Baalebulb sp., Dardarnus sp. and Moggridgea tingle (Main, pers. comm., 1989; Main, 1991). The fauna of the mostly saline lower reaches of the Frankland and Deep Rivers tends to be also found in the inlets, although species diversity and numbers vary because of different salinity levels. Common species include the crustacean Gladioferens imparpies, the benthic (bottom-dwelling) worm Ceratonereis aequisetes, the shellfish Arthritica semen, the Wide-mouthed Lamprey (Geotria australis) and Black Bream (Lenanton, 1974). The Mud Minnow (Lepidogalaxas salamandroides) is confined to the peaty swamps. ISSUES Mammals • The Southern Brown Bandicoot, Chuditch, Western Ringtail Possum and six other mammals are vulnerable to frequent fires, either indirectly through immediate loss of nectar for food (for example, the Honey Possum) or through the loss of overhead cover and an open ground layer (for example, the Quokka). The Honey Possum is also vulnerable through the introduction and spread of dieback disease since much of its food comes from plants susceptible to the disease (see the Resource Document, Table 24). Birds • Sites within the Park are included in the management and translocation program for the threatened Noisy Scrub-bird. These sites cannot be burnt, although prescribed burning may be necessary in adjacent areas to protect the sites from fire. Small areas of suitable habitat for the Western Bristlebird also occur in the Park, although this species no longer exists in the Park. 31
