ABSTRACT Forty -one remnant vegetation areas in the central and north - eastern Mount Lofty Ranges have been surveyed, evaluated and ranked for their scientific significance. Although it would be desirable to retain many of these blocks in their entirity, it is accepted that this would be unrealistic in light of other society needs. However, it is recommended that areas with a high ranking receive conservation priority.Similarly, priority should be given to the retention of associations with a high rating within each site. It is further recommended that specific attention be given to the five sites ranked 1 - 4. These warrant particular consideration for incorporation within the parks and reserves system, being sites characterized by a relatively large size (greater than 100 ha) and diversity of plants and plant communities. PREFACE This study was prepared by Mr. L. Mitchell and Ms. A.Prizibilla, research biologists, on contract for the Departmentfor the Environment. They were supervised by Mr. T. Dendy, an EnvironmentalOfficer of the Department. 1. INTRODUCTION The original vegetation and wetlands of the Mount Lofty Rangeshave been greatly depleted. Remnant areas of this resource now cover less than 7% of the Ranges( Counties Adelaide and Hindmarsh). Much of this depletion has occurred since the Second World War due predominantly toagricultural developments, but also as a result of forestry, waterconservation, land drainage and home building activities.
