planted in Walpole, and blackberry can spread rapidly and thrive in environments that are wet in summer. • Grassy weeds, such as veldt and pampas grass, are a potential threat in areas of the Park that are frequently burnt and adjacent to farmland. • South African members of the Iridaceae family (for example, Watsonia bulbifera, Gladiolus undulatus), which are present in the Park, and the arum lily (Zantedeschia aethiopica) could become dominant members of the plant community because of their potential to colonise. • Rubbish tips and settlements are a source of weeds such as kikuyu (Pennisetum clandestinum), castor oil plants (Ricinus communis) and black night shade (Solanum nigrum). • Plant communities such as Acacia littorea dune community (type 9), granite outcrops (type 13) and swamp communities (type 14), are most susceptible to weeds (see Section 7.0 Flora, Table 4 for vegetation community types). Frequent fires need to be avoided to ensure weeds do not proliferate. • Other weeds with potential to spread quickly in the Park are branched onion weed (Trachyandra divaricata) and penny royal. OBJECTIVES • Control or, if possible, eradicate weeds that have the potential to cause major environmental problems. • Minimise any detrimental side effects that control measures may have on the Park. ACTIONS 1. Map the incidence of weeds, monitor their location, extent, effectiveness of control programs and, where possible, ecological effects. 2. Conduct control programs in areas of: • greatest conservation value • greatest perceived environmental threat • small new infestations. 3. Instigate control programs of the following: invasive bulbous plants (for example, Watsonia) 48
• blackberry • pampas grass • arum lily • woody weeds 4. Liaise with the Agriculture Protection Board, adjacent landholders and local authorities regarding weed control on Park boundaries and adjacent properties. 5. Investigate use of volunteers to help in weed mapping and control programs. 6. Liaise with adjacent landholders to minimise fertiliser drift into the Park. 7. Avoid unnecessary disturbance associated with management actions, such as road maintenance and frequent burning, particularly adjacent to sources of weeds. 8. Ensure that all earth-moving machinery is thoroughly cleaned before entering the Park. 9. Liaise with townspeople to discourage garden cultivation of any species which may be a threat to the Park. 10. Remove exotic trees where considered necessary. If the trees are to be taken under licence and sold, follow the approval conditions of the CALM Act. Research and Monitoring 11. Monitor known priority flora populations for weed invasion. Take control measures as necessary. 12. Monitor weed invasion. Use the results to modify management practices or instigate control measures. Monitor results of control methods. 12.0 FERAL ANIMALS BACKGROUND Foxes, dogs, Kookaburras, cats, pigs and rabbits occur in the Park. Nonetheless, the full extent of feral animals in the Park is unknown. Fauna particularly susceptible to feral animals include the Noisy Scrub-bird, Honey Possum, Quokka, Chuditch, Pygmy Possum, Common Brushtail Possum and Western Ringtail Possum. 49
