BYRON FLORA AND FAUNA STUDY, 1999 included Blue Flax Lily, Climbing Guinea Flower and Breynia. Site BB42 was located on metasediments at Broken Head. Brush Box, Blackwood, Umbrella Cheese Tree, Camphor Laurel and Blueberry Ash were all present in the upper stratum. Guioa, Common Silkpod Parsonsia straminea, Celerywood Polyscias elegans and Brown Bolly Gum comprised the midstratum. The lower stratum included Lantana, Coast Banksia, Native Olive, Tuckeroo, Beach Acronychia and the introduced Red Cherry Guava Psidium cattleianum. The ground stratum was dominated by a grass Oplismenus undulatifolius. 4.7.8 Swamp sclerophyll forest Mixed eucalypt spp.(mE2) (Sites PS10, P8, BB34) Mixed eucalypt described forest with various combinations of the following species as co-dominants – Forest Red Gum, Red Mahogany, Swamp Mahogany, Swamp Box, Flooded Gum, Tallowwood, Blackbutt, Pink Bloodwood +/- Paperbark. This forest usually contained species associated with swamp communities (Paperbark, Swamp Mahogany, Swamp Box). Most mixed eucalypt forests were mapped on aeolian and alluvial soils with smaller areas recorded on sediments, estuarine soils and basalt. At Marshalls Creek, Site P8 was located on sediments of mixed aeolian/estuarine-alluvial origin. The upper stratum comprised Eucalyptus robusta x tereticornis, Swamp Mahogany Eucalyptus robusta, Forest Red Gum, Tallowwood, Flooded Gum, Pink Bloodwood and Swamp Box. The midstratum included Swamp Box, Brush Box, Umbrella Cheese Tree, Camphor Laurel and Paperbark. The ground stratum comprised Swamp Water Fern and Tall Saw Sedge, Settler’s Flax Gymnostachys anceps, Harsh Ground Fern and the introduced Whisky Grass Andropogon virginicus. At Broken Head, Mixed eucalypt forest was recorded on Pleistocene sands (BB34). The upper stratum comprised Blackbutt, Tallowwood, Pink Bloodwood and Swamp Box. Coast Banksia, Paperbark, Blueberry Ash and Hard Corkwood were present in the midstratum. The ground stratum included Bracken Fern, Corky Milk-vine Marsdenia lloydii, Blue Flax Lily and Spiny-headed Mat-rush. Paperbark (PB) Paperbark +/- Swamp Oak Casuarina glauca /Pink-flowered Doughwood-Bangalow Palm- Umbrella Cheese Tree (Sites BB3, BB1, BB4, H6, PS1, PS5, PS7, PS13, PS12, PS14, PS16, PS26, P6, BB10, BB11, LE759, LE771, BB21, P14) The low-lying, regularly inundated acid peat areas of the region contained remnant and regrowth Paperbark (Photo 7). Paperbark was mainly recorded on aeolian sands, swamp and alluvium. Smaller areas were mapped on metasediments, sediments and on disturbed soils. Swamp Oak was occasional to co-dominant where salinity increased. With build up of soil levels above regular inundation levels or where alluvial soils graded in, Bangalow Palm, Umbrella Cheese Tree and Pink-flowered Doughwood Melicope elleryana occurred. Paperbark was recorded on aeolian sands at Ewingsdale wetlands (Site PS1). Paperbark, Umbrella Cheese Tree and Brown Kurrajong were present in the upper stratum. The midstratum included Bangalow Palm and Umbrella Cheese tree and the ground stratum comprised Mistweed, Bangalow Palm and Cunjevoi Alocasia brisbanensis. Another site at Ewingsdale wetlands on Pleistocene sands (PS5) comprised Paperbark with Blackwood in the upper and mid strata. The ground stratum included Swamp Water Fern and Climbing Maidenhair Fern Lygodium microphyllum. At Taylors Lake, Site LE771 was located on coastal (Holocene) sands. Paperbark dominated the upper stratum. The mid and lower strata were absent. Bare Twig-rush Baumea juncea, Shield Fern Cyclosorus interruptus and Common Reed Phragmites australis were present in the ground stratum. 51
A GREENPRINT FOR A SUSTAINABLE FUTURE Paperbark was recorded on alluvial soils at Skinners Shoot (Site BB1). Paperbark formed a canopy over a mid and lower stratum dominated by Pink-flowered Doughwood, Bangalow Palm and Umbrella Cheese Tree. Camphor Laurel was also present. The ground stratum was dominated by Eared Swamp Fern and Cunjevoi. Swamp Mahogany/Swamp Box (SMB) Swamp Mahogany +/- Paperbark +/- Scribbly Gum +/- Swamp Box Swamp Box +/- Paperbark +/- Swamp Mahogany (Sites BB2, PS9, PS15, PS32, PS34, PS35, LE761, BB15, BH8) Swamp Mahogany and Swamp Box were recorded mainly on aeolian sands with smaller areas mapped on metasediments and on alluvial soils. Swamp Mahogany was recorded on aeolian sands to the west of the Caravan Park on Ewingsdale Road (PS32). Swamp Mahogany dominated the upper stratum with Pink Bloodwood sub-dominant. The midstratum comprised Swamp Mahogany, Blueberry Ash and a teatree Leptospermum speciosum. The lower stratum included Soft Corkwood Duboisia myoporoides, Red Kennedy Pea Kennedia rubicunda and Blueberry Ash. Tall Saw Sedge, Tree Shaggy Pea and Feather Plant dominated the ground stratum. Swamp Box was found on metasediments at Honeysuckle Hill (PS15) with Camphor Laurel and Coast Banksia also present in the upper stratum. The midstratum included Coast Banksia, Camphor Laurel, Bitou Bush and Coast Canthium Canthium coprosmoides and the ground stratum comprised Bracken, Spiny-headed Mat-rush and Blady Grass. Site BH8 was located at Marshalls Creek on mixed aeolian-alluvium soils. Swamp Mahogany and Eucalyptus robusta x tereticornis were co-dominant in the upper stratum. The mid and lower strata included Paperbark, Umbrella Cheese Tree, Swamp Box, Pink-tipped Bottlebrush, Winter Senna, Small-leaved Fig Ficus obliqua and Blueberry Ash. The ground stratum was dominated by Swamp Water Fern and Tall Saw Sedge. At Broken Head, Site BB15 was located on sediments. Swamp Mahogany dominated the upper stratum. The mid and lower strata comprised Paperbark, Umbrella Cheese Tree, Bangalow Palm and Callicoma. The ground stratum included Pouched Coral Fern Gleichenia dicarpa, Eared Swamp Water Fern, Swamp Water Fern, Frogmouth Philydrum lanuginosum, a palm-lily Cordyline rubra and Climbing Maidenhair Fern. At New Brighton, near Marshalls Creek Site LE761 was located on aeolian sands. Swamp Box dominated the upper stratum with Umbrella Cheese Tree and Pink Bloodwood also present. The mid and lower stratum included Brush Ironbark Wattle, Scentless Rosewood and Lantana. Spiky-headed Mat-rush and Austral Sarsaparilla Smilax australis dominated the ground stratum. Swamp Oak +/- Paperbark (sOP) (Sites BB38, PS31, LE762, LE763) Swamp Oak was mapped mainly on aeolian sands and on alluvial soils derived from metasediments and rhyolite. Areas of Swamp Oak occurred in areas where tidal inundation had increased ground water salinity. As salinity decreased Paperbark graded in. Site BB38 was located at southern Broken Head on coastal sands (possibly Holocene). Swamp Oak dominated the upper stratum with Paperbark and Blackwood also present. The midstratum was absent. Harsh Ground Fern dominated the ground stratum. At New Brighton Site LE762 was located on aeolian sands. Swamp Oak dominated the upper stratum. The midstratum included Beach Acronychia, Paperbark and Native Cottonwood Hibiscus tiliaceus. The ground stratum included Bare Twig-rush and Native Violet Viola hederacea. 52
