Hindmarsh, Inman and Bungala Estuaries, South Australia, Australia
Client – Adelaide and Mount Lofty Ranges Natural Resource Management Board
Services – Marine and Coastal, Flora and Fauna, Planning and Compliance, Community Consultation
Assignment – The project was undertaken to develop a regional monitoring and evaluation plan for the Hindmarsh, Inman and Bungala estuaries. The monitoring plan will monitor the long-term impact of actions undertaken as a result of the Estuary Action Plans, which were prepared for these estuaries in 2008.
Our Role – Baseline assessments were first undertaken to obtain information from the three target estuaries to guide the development of a long-term monitoring program. Baseline assessments at all three estuaries included:
- rapid assessment of habitat using the Rapid Appraisal of Riparian Condition (RARC) methodology
- site assessments of native flora and weed distributions
- recording any sightings of significant native fauna and pest species
- GIS mapping of the distribution of the swamp paperbark. The health of the trees were assessed using GIS polygons to determine a compactness ratio. Repeat surveys of the same areas will assess the population health of the trees.
Following from the baseline assessments data, analysis and technical papers were produced. Recommendations were made for vegetation management, especially for exotic species. The monitoring plan provided detailed rationales and methods for each of the recommended elements. The program took into account relevant compliance standards, for example, nationally agreed Estuarine, Coastal and Marine Resource Condition Indicators from the National Land and Water Resources Audit.
