CH_WSF06are often dense especially in less disturbed examples of this community. The ground layer is often sparse andconsists mainly of Gristle Fern (Blechnum cartilagineum) and Spiny-headed Mat-rush (Lomandra longifolia).Common on the lower and middle slopes of the eastern Dorrigo plateau above the escarpment rim (about 500mASL) on soils of sedimentary and metasedimentary origin.Floristic summaryLayer Height (m) Cover (%) Dominant SpeciesTallest 5 - 45 25 - 50 Eucalyptus saligna, Eucalyptus microcorys, Eucalyptus pilularis, Lophostemonconfertus.Middle 1 0.5 - 20 30 - 80 Callicoma serratifolia, Acacia melanoxylon, Tristaniopsis collina, Alphitoniaexcelsa.Middle 2 3 - 20 25 - 70 Cryptocarya glaucescens, Cryptocarya rigida, Trochocarpa laurina, Synoumglandulosum subsp. glandulosum, Persoonia media, Archirhodomyrtusbeckleri, Duboisia myoporoides, Parsonsia straminea.Lower .01 – 0.5 5 - 65 Blechnum cartilagineum, Lomandra longifolia, Gahnia aspera,Pseuderanthemum variabile, Pratia purpurascens, Panicum pygmaeum,Lobelia trigonocaulis, Doodia aspera.* Structural data collated from 10 of 11 full floristic sitesStructural and floristic variationsThe canopy dominance of this community is varied across its distribution. Strong dominance of Sydney BlueGum (Eucalyptus saligna), Flooded Gum (Eucalyptus grandis) and Tallowwood (Eucalyptus microcorys) which haveall been recorded, though a mix of these species is the most common occurrence. The dense mid stratum ofpredominantly warm temperate shrubby species is consistent throughout all occurrences. There is an exampleof this community where Tallowwood (Eucalyptus microcorys) is the only canopy species that occurs alongCoopernook Creek Road in Dorrigo National Park. This community also occurs with a high proportion of FloodedGum (Eucalyptus grandis) in various areas around the eastern Dorrigo plateau including Wild Cattle Creek StateForest near Coopernook Creek and some areas near Eve Creek.ExoticsAraujia sericifera, Cinnamomum camphora, Passiflora subpeltata, Solanum mauritianum,Solanum pseudocapsicumSpecies richnessNumber of plots 11Total species 140Average number of species 31 ±11.5Conservation statusThis community is reserved in Bindarri NP (213ha), Dorrigo NP (134ha) and Bindarri SCA (18ha).TenureArea (ha)Crown Land 66Freehold 2122National Park 349NSW State Forest 1400State Conservation Area 18TOTAL 3956Vegetation Mapping of the Coffs Harbour Local Government Area Page 107
