Survey/Project Name: RIVER TORRENS LINEAR PARK WEED SURVEY
Abstract: This project aims to recorded and map non-native plant species, including pest plants, along the River Torrens Linear Park in metropolitan Adelaide; South Australia. The linear park is surrounded by urban environment and passes through nine local government areas. The highly modified riverine corridor is used for conservation, recreation, education, transport, water quality management and other community uses, and extends from Gulf St Vincent to the foothills of the Mount Lofty Ranges. The project was commissioned by the Natural Resources Adelaide and Mount Lofty Ranges to facilitate coordinated planning and implementation of pest control. A number of field surveys were undertaken (spring and summer) to determine the extent of pest damage across the Linear Park, including a comprehensive weed survey and opportunistic feral animal survey. The mapping of the weed infestations involved sampling exotic flora, mapping individuals and extent of patches, and determining the abundance ratings of each weed species within each patch. A comprehensive exotic plant species list was also recorded for each patch, and an assessment of the level of risk posed to particular park assets, when relevant. Management units were defined according to management issues identified and local government area. Pest plant control priorities and actions were recommended for each management unit.

Study Area Description: The River Torrens Linear Park between the coast of Gulf St Vincent and the foothills of the Mount Lofty Ranges in the City of Tea Tree Gully Local Government Area.
Objectives
         Vegetation: The River Torrens Linear Park Pest Management Plan aims to achieve the following objectives: Update and record the current base-line condition of the Linear Park including biodiversity; amenity and heritage assets; Identify and map all current and potential pest plant species to enable planning of pest plant management; setting of priorities and monitoring of outcomes.
         Fauna: Opportunistic feral animal sightings may be recorded.
Methodology
         Vegetation: The mapping of the weed infestations involved sampling exotic flora; mapping individuals and extension of patches and determining the abundance ratings of each weed species within each patch. A comprehensive exotic plant species list was also recorded for each patch and an assessment of the level of risk posed to particular park assets; when relevant. The extent of non-native plant infestations was mapped as follows: Individuals and small patches were recorded with a single GPS point. The extent of large patches was mapped using GPS start and end points and aerial photography.
         Fauna: *** No vertebrate methodology recorded
