2007 Wetland Inventory for the Eyre Peninsula

10.0 TENURE AND MANAGEMENT AUTHORITY10.1 BackgroundThe type of management authority and tenure surrounding a wetland often dictates the type and level ofprotection and management for the wetland. An understanding of this parameter also allows considerationof different legislation and approaches concerning on-site management and planning for wetland areas.Tenure and management25Occurrence of wetlands20151050PrivateLocalgovernmentStategovernmentNo dataType 20 4 5 4TypeFigure 2. Tenure and management10.2 AnalysisPrivate tenure and management was the most common occurrence with 20 sites recorded. This suggeststhat the management of wetlands surveyed on Eyre Peninsula lies with private landholders. This factor hasimplications for the management of wetlands for biodiversity, and highlights the importance of off reserveconservation programs.11.0 ENVIRONMENTAL REGIONS11.1 BackgroundLaut et al (1977) described and mapped South Australia hierarchically into Environmental Provinces,Environmental Regions and Environmental Associations. The three tiers are based on geologicalformations and vegetation type. Eyre Peninsula is part of the Eyre and Yorke Peninsula Province. Thisprovince is divided into six Environmental Regions, which are based on vegetation criteria. The wetlandsurvey is contained within three of these regions.The Southern Highlands and Plains Environmental Region encompasses the southern section of theuplands of the Koppio Hills and along the east coast of Eyre Peninsula, and the undulating to low hillyplains to the west. The western boundary represents a change from duplex soils on the hilly or undulatingcountry to sands and calcarenite plains, the north is defined by inland dune landforms (Laut et al 1977).The West Coast Environmental Region is comprised predominantly of undulating to hilly plains oncalcarenite with local rises and the occasional steep-sided hills on quartzite on the west side of EyrePeninsula. Dunes are restricted to the coastal fringe where they occur in association with lagoons and lakes(Laut et al 1977).15
