Hunter May 2011 23 Kendall Rd, Invergowrie NSW, 2350 Ph. & Fax: (02) 6775 2452 Email: [email protected] A Report to the New South Wales National Parks and Wildlife Service & the Nature Conservation Trust of NSW i Vegetation of Butterleaf & Bezzants Lease Summary The vegetation of the Butterleaf National Park and State Conservation Area and Bezzant’s Lease is described and mapped (scale 1:25 000). Nine communities and three sub-associations are defined based on classification (Kulczynski association). These eight communities and three sub-associations were mapped based on ground truthing, air photo interpretation and landform. The communities described and their status is: Floristic Community Area Reservation Status C1a: Eucalyptus radiata – E. Not listed as a community of concern though 1,875 ha campanulata – E. obliqua likely a unique association within the area. C1b: Eucalyptus obliqua – E. Not listed as a community of concern. 263 ha brunnea – E. saligna C1c: Eucalyptus campanulata Not listed as a community of concern. 250 ha – E. obliqua – E. saligna C2: Eucalyptus acaciiformis – Likely to be included as an Endangered Angophora floribunda Ecological Community within the Montane 8.7 ha Peatlands and Swamps determination of the TSC Act. C3: Eucalyptus caliginosa – Not listed as a community of concern though E. bridgesiana – E. 433 ha likely a unique association within the area. laevopinea C4: Eucalyptus nova-anglica Would fall within the Endangered Ecological – E. acaciiformis – E. 39.8 ha Community New England Peppermint subtilior Woodland on the TSC and EPBC Acts. C5: Leucopogon neo-anglicus Not listed as a community of concern. Currently – Kunzea obovata – adequately reserved across its range. 138 ha Leptospermum novae- angliae C6: Eucalyptus campanulata Not listed as a community of concern though a – E. radiata – E. 3,071 ha highly disjunct and rare association. williamsiana C7: Callicoma serratifolia – Not listed as a community of concern. 34.7 ha Orites excelsa C8: Baeckea omissa – Epacris Included as an Endangered Ecological microphylla 76.2 ha Community within the Montane Peatlands and Swamps determination of the TSC Act. C9: Leptospermum novae- Not listed as a community of concern, though a angliae – Leptospermum 10.5 ha rare assemblage within the landscape, especially polygalifolium in good condition. A total of 516 vascular plant taxa were found from 99 families and 276 genera. Muehlenbeckia costata and Chiloglottis platyptera are currently listed as vulnerable Dr John T. Hunter (02) 6775 2452 ii Vegetation of Butterleaf & Bezzants Lease on the EPBC Act, no other species of state or federal significance were found though seven other RoTAP species were noted which include: Agiortia cicatricata, Brachyloma cicatricata, Callistemon pungens, Cryptandra lanosiflora, Eucalyptus codonocarpa, Eucalyptus retinens, Hibbertia villosa, Philotheca epilosa. Acacia mitchellii, Actinotus gibbonsii, Callitris rhomboidea, Isotoma axillaris, Tmesipteris parva, Trachymene sp. nov. were also considered to be of regional conservation significance. Dr John T.
