Southern Mount Lofty Ranges Biological Survey APPENDIX I DESCRIPTION OF ENVIRONMENTAL ASSOCIATIONS OCCURRING IN SURVEY REGION BOUNDARY. Part 1. Environmental associations in study area occurring within FLEURIEU IBRA sub-region Environmental Total % of Description Association Area vegetation (ha) remaining 3.2.1 Mt. Rapid 12,763 3.9 Hills and ridges on interbedded shale and arkose, locally overlain by tillite. Relict fans form broad flat surfaces near Cape Jervis where some coastal cliffs occur. Open parkland with sown pasture is used for livestock grazing. The scenery of the coastline is dominated by tall cliffs that vary in form and steepness, the amount of rock outcrop and vegetative cover. 3.2.2 Deep Creek 12,984 30.2 A long dissected ridge of phyllite and greywacke with cliffs, or beaches and dunes along the coastline. The cover is predominantly open parkland over sown pasture with widespread remnants of woodland and forest. Inland views tend to be middle-ground panoramic, featuring grassy ridge crests and valley floors with bracken and reed or remnant forest vegetation. 3.2.3 Fleurieu 30,389 15.6 An undulating to hilly dissected tableland on lateritized sandstone. There is a mixed cover of open parkland, forest plantation and woodland. 3.2.4 Inman 37,130 4.4 A series of low dissected ridges and spurs on tillite and arkose, with dunes and beaches or Valley cliffs along the coast. The cover is open parkland over sown pastures and cereal crops. 3.2.5 Bob Tiers 15,761 21.3 Ridges on schist and gneiss with dissected slopes and remnantsof laterite-capped tableland. Open parkland with an understorey of sown pastures and heath is used for grazing livestock. The smooth hill and ridge crests are generally cleared, but remnants of native forest are common on lower slopes and in valleys, and are frequently left along roadsides. 3.2.6 Kerby Hill 10,433 3.2 Ridges on greywacke and remnants of laterite-capped tableland. There is a cover of open parkland with an understorey of sown pastures, cereal crops and heath. 3.2.7 Sandergrove 53,774 2.9 An undulating plain on tillite with areas of calcrete merging into alluvial fans. The cover is open parkland and cropland. Remnants of mallee vegetation are local features in this predominantly agricultural landscape. 3.2.8 Scotts Hill 97,645 0.3 Structurally controlled ridges with steep slopes, on metasediments. There is cover of open parkland with an understorey of sown pasture. Views are often impressive due to the stark nature of the landscape, formed by grass covered hills, often without any tree growth, frequent rock outcrops, and steeply incised valleys, locally steepening into gorges. 3.2.9 Bull Knob 9,231 13.4 Ridges with dissected slopes on quartzite and arkose. The cover is parkland with an understorey of sown pasture. Below the crests landscape dimensions quickly diminish and views are frequently foreground enclosed or perspective along valley floors, which with willows, poplars, pine trees and blackberry undergrowth contrast sharply with the grasslands or open blue gum woodlands of the hills. 3.2.17 Eden Valley 68,882 0.5 An undulating upland plain on metasediments with broad interfluves and occasional higher hills. The cover is mainly open parkland over sown pastures, with some pine plantations and vineyards. 265 Part 2. Environmental associations in study area occurring within MT. LOFTY IBRA sub-region REGION Environmental Total % of Description vegetation Association Area remaining (ha) 3.2.10 Mt Compass 31,668 7.2 Hills and ridges on tillite and schist with isolated laterite-capped tableland remnants, broad floodplains and alluviated upland basins. The river valleys characteristically provide perspective views in which irrigated pastures are notable features. 3.2.11 Mt Wilson 15,284 1.5 Steep ridges and hills on interbedded metasediments and limestone, with beaches or coastal cliffs. The foreground is usually dominated by grassy, rounded hill crests and frequently steep, rocky sideslopes. 3.2.12 Aldinga 26,475 1.6 Fans with areas of calcrete on the surface, merging into a gently undulating plain with occasional laterite-capped tableland remnants. Cliffs alternate with beaches and dunes along the coastline. There are three major forms of cover: cropland pastures on the plain; horticultural plantations on the fans and open parkland over grazed pastures on the steeper slopes. 3.2.13 Clarendon 28,050 28.4 Hilly uplands with dissected lateritic tableland remnants. There is cover of mixed open parkland, forest and woodland, with small areas of orchards. Most of the association is used for grazing but much grazing land as well as forest and woodland areas are part of a recreational resource for metropolitan Adelaide. 3.2.14 Mt Terrible 17,903 33.2 Ridges and hills with steep slopes on metasediments. There is a mixed cover of open parkland over pastures and orchards. Much of the association is urban fringe, and is part of a recreational resource for metropolitan Adelaide. 3.2.15 Uraidla 14,411 22.0 Hilly uplands on sandstone and shale with long smooth slopes. The cover is parkland and orchards. Much of the association is urban and urban fringe, and is part of a recreational resource for metropolitan Adelaide. The combination of dissected topography, intensive land use and generally lush growth due to the high rainfall, has made this landscape intricate and unique, as a view from the Mt Lofty summit will show. 3.2.16 Hahndorf 61,693 3.5 An undulating to hilly high plain on shale with narrow, northerly trending quartzite strike ridges. Thereis a mixed cover of parkland with an understorey of sown pastures, orchards and some plantation forests. 3.2.18 Barossa 13,962 4.5 An intramontane basin below gentle footslopes and fans. There is a cover of vines and limited parkland with a pasture understorey. 3.2.19 Para 34,863 23.5 A hilly upland with broad crests and dissected slopes on schist and gneiss. There is a mixed cover of pine plantations and open parkland with an understorey of sown pasture. 3.2.20 Bare Hill 13,129 10.6 Densely dissected uplands on siltstone. The cover is predominantly open parkland over sown pasture with some orchards and vegetable cultivation. 3.3.1 Rosedale 32,888 2.2 An undulating to rolling plain on shale with broad floodplains. The cover is predominantly open parkland with an understorey of sown pastures and some vines. 266 Southern Mount Lofty Ranges Biological Survey APPENDIX II FAUNA SURVEY QUADRATS SHOWING SELECTED VEGETATION AND PHYSICAL PARAMETER DETAILS. A TOTAL OF 157 QUADRATS WERE SURVEYED FROM THREE BIOLOGICAL SURVEYS. Notes The first two or three figures in “Quadrat No.” column represent the survey number namely, 117 = survey 117, 52 = survey 52 and 97 = survey 97. Vertebrates: All quadrats were surveyed for vertebrates. Hair tube sampling was conducted at 100 of the 111 survey 117 quadrats. The 11 quadrats at which hair tube sampling was excluded are followed by an asterisk. (*) Invertebrates: Quadrats in bold were surveyed for invertebrates (74 quadrats).
