Coastal Assets
Wedge Island Nature Reserve
The Wedge Island Nature Reserve forms part of the ~111 180 ha Jurien Bay Marine Park which was declared in 2003. The island is also part of the Turquoise Coast islands nature reserve group. Wedge Island differs from the other islands in that it is periodically joined to the mainland by a wide sandbar. This has historically enable access and led to more widespread erosion and weed invasion than is evident on the other islands.
Primary and Secondary Coastal Dunes
Primary dunes (from low water mark) and secondary dunes. Valued for recreational, aesthetic and cultural reasons, along with the services provided for storm protection and habitat.
Marine Assets
Seagrass Meadows
Seagrasses are flowering plants that complete their life cycle submerged in seawater. Western Australia has the world’s highest diversity of seagrasses, with 27 species occurring in shallow waters off the coast. Seagrasses form a vital component of marine ecosystems through their services as primary biomass producers, sources of habitat (including breeding and nursery areas) and dissolved oxygen, sediment traps, and nutrient cycling. Seagrass distribution is determined by a combination of shelter, sediment, turbidity, nutrient, temperature, current and tidal influences.
Extensive seagrass meadows occur in protected near-shore areas of the NAR, where clear water, low nutrients and sandy sea floors prevail, and are dominated by the long strap-like Ribbonweed or Strapweed (Posidonia spp) and the thin-stemmed Wireweed (Amphibolis spp).
Seagrass habitats are fragile and susceptible to damage and can take many years to recover from disturbance, such as physical damage/removal and shading due to algal blooms (as a result of increased nutrients), and sedimentation (due to dredging activities and erosion in catchment areas).
More information on seagrasses in Western Australia can be found in the following publications: Flowers of the Ocean: WA’s Expansive Seagrass Meadows; The Wonders of Weed Information Sheet; Fisheries Fact Sheet: Seagrasses; Establishing Reference and Monitoring Sites to Assess a Key Indicator of Ecosystem Health (Seagrass Health) on the central west Coast of Western Australia (see references).

It supports a population of the Vulnerable Jurien Bay Skink Liopholis pulchra longicauda, Endangered Dibbler Parantechinus apicalis and relatively high plant diversity.
Groundwater Areas
Jurien Groundwater Area
The Jurien Groundwater Area spans over 5,000 km2 of land and has a total groundwater availability of around 84 million m3/year. Groundwater usage is low, with 21 per cent of resources allocated. There are also significant amounts of groundwater available in the Parmelia/Leederville formations. The superficial formation contains important resources near the coast, although the quality and quantity of groundwater is variable (DoW, 2010).

Rivers
Nambung River
River Length (km) Key Characteristics Nambung 22 The Nambung River meanders between the towns of Cervantes and Badgingarra. The river ceases within the Nambung National Park in Karst terrain approximately 9 km south east of Cervantes. Hill River
Drainage Basin Length (km) Catchment Area (km2) Average Stream Salinity (mg/L) Key Characteristics Moore-Hill 124 3,721 1000-3000 Originates east of Badgingarra and enters the ocean halfway between Cervantes and Jurien. The estuary is blocked by a sandbar for most of the year and the rivers major tributaries are the Munbinea, Coomallo, Boothendarra and Winjardie Creeks. The lower reaches are also groundwater fed.
Wetlands
Saline lakes of Coolimba – Jurien
Lake Thetis
Lake Thetis is one of few lakes where both submerged benthic microbial mats and developing microbial structures occur. The shallow pools on the south western shore provide the perfect environment for the growth of micro-organisms, particularly cyanobacteria, which are the building blocks for stromatolites, the regions only example of ‘living fossils’. Stromatolites – layered rocks – are the oldest form of life on earth dating 3.5 billion years, although the Lake Thetis structures are relatively new, being about 2,000 years old. Stromatolites grow in Lake Thetis because of the extreme salinity and limited circulationof the water and the occurrence of calcium carbonate. Lake Thetis is a very important site in the region and a significant example of a specialised form of aquatic ecological community.
A symposium on Western Australia’s south-west microbialites during October 2012 developed a number of methods of addressing the major issues with conservation management of WA’s microbialites and microbial assemblages including increased sharing of knowledge and community ownership.
