Estuarine Mangrove ForestEstuarine SaltmarshThese succulent herbs and rushes growing on tidal land are a component of Saline communities. Landfill has destroyed many areas of saltmarsh on the lower and mid Georges River. These communities occur in or just above salty tidal areas
of the river. Various communities often have distinct edges that separate one from the other, such as mangroves, saltmarsh, She Oak forest and reedlands.

Sydney Turpentine-Ironbark ForestA component of Shale and Sandstone transition communities, this tall open forest on shale and shale-enriched sandstone soils was once common in Sydney but was targeted for timber production. Characterised by a diverse midstory, grassy ground
cover, and a canopy of small trees dominated by Turpentine, Red Mahogany, Sydney Red Gum and various Ironbark species.
Cumberland Shale Plain WoodlandA component of Shale communities, this grassy woodland is characterised by open gentle topography, high biodiversity within the ground cover layer, and low rainfall areas on deep clay soils derived from Wianamatta Shale. The canopy is dominated by
Grey Box, Red Gum, Rough Barked Apple and Narrow Leaved Ironbark. The midstory is dominated by Blackthorn and Hickory Wattle. The grassland is a diverse mix of grasses such as Kangaroo Grass and Barbed Wire Grass.

GEORGES RIVER CATCHMENTKEY ENDANGERED ECOLOGICAL PLANT COMMUNITIES
THE GEORGES RIVER CATCHMENT
The Georges River begins its journey approximately 60km south-west of Sydney in the town of Appin. From here the river flows north towards Liverpool, through the Chipping Norton Lakes, then east until it reaches Botany Bay.
The catchment area of the Georges River covers an area of approximately 960 km2 and, with over 1.2 million people living within its boundaries, is one of the most highly urbanised catchments in Australia.
The river has a number of important tributaries including Bunbury Curran Creek, Cabramatta Creek, Prospect Creek, Williams Creek, Salt Pan Creek, Mill Creek, and the Woronora River.
PARTNERSHIPSIN ACTIONIn addition to the GRCCC’s nine member councils, the Georges Riverkeeper Program has established a wide array of partnerships which reflect stakeholders’ interest in keeping the Georges River a clean, safe and beautiful place to visit.
Program partners include:
Corrective Services NSW; Intensive Correction Order Teams
National Green Jobs Corps National Parks and Wildlife ServiceNational Parks Association Conservation Volunteers Australia

UPPER GEORGES RIVER SUBCATCHMENTBUSH REGENERATION = 1,235 M2 PLANTINGS = 0 COMMUNITY SERVICE HOURS = 205RUBBISH COLLECTION = 3,740 KGs COMMUNITY SERVICE HOURS = 388
The Upper Georges River catchment is characterised by numerous creeks and tributaries that carry large volumes of water during rain events and seasonal flows. These creeks and tributaries drain urban and industrial areas, transporting large amounts of rubbish into the river, which accumulate along the foreshores, degrading the natural environment.
Bush Regeneration teams target the removal of African Olive, African Boxthorn and Privet in remnant Cumberland Plain Woodland.
*Open River - Upper Georges River corresponds to all remaining worksites on the main river foreshore.
MID GEORGES RIVER SUBCATCHMENTBUSH REGENERATION = 17,166 M2 PLANTINGS = 3,148 COMMUNITY SERVICE HOURS = 3,702RUBBISH COLLECTION = 18,389 KGs COMMUNITY SERVICE HOURS = 2,664
Wind patterns and tidal influences at Chipping Norton Lakes and Salt Pan Creek contribute to the accumulation of large amounts of rubbish on a regular basis. Prospect Creek has been negatively impacted by a high degree of urbanisation. Mangroves and reedlands in the riparian areas of the Mid Georges River catchment help to filter and collect rubbish along this stretch of the river.
*Open River - Mid Georges River corresponds to all remaining worksites on the main river foreshore.
LOWER GEORGES RIVER SUBCATCHMENTBUSH REGENERATION = 1,543 M2 PLANTINGS = 0 COMMUNITY SERVICE HOURS = 546 RUBBISH COLLECTION = 10,673 KGs COMMUNITY SERVICE HOURS = 1,773
Rubbish is typically collected from Mangrove Forests and along open bay beaches. Lower River foreshores are often a mixture of seawalls and rocky foreshores, which prevent rubbish from accumulating on the shoreline. Rubbish in the lower river ends up at Towra Point, Quibray Bay and Woolooware Bay.
*Open River - Lower Georges River corresponds to all remaining worksites on the main river foreshore.
Bush regeneration works in the region include the targeted removal of Balloon Vine, Madeira Vine and Lantana in remnant Cumberland Riverflat Forest.
Removal of noxious and environmental weeds such as Lantana, Bitou Bush, Mother-of-Millions and Balloon Vine in riparian sandstone communities and on Botany Bay foredunes.
TOTAL CATCHMENT BUSH REGENERATIONRiverkeeper Program regeneration teams are restoring degraded, remnant bushland on foreshores, creeks and tributaries identified by councils across the catchment. Work is being undertaken along the river system to improve ecological health and species biodiversity. Riverbank vegetation provides habitat for local flora and fauna, prevents erosion and sedimentation and filters stormwater runoff, which in turn protects and improves water quality.

TOTAL CATCHMENT RUBBISH COLLECTIONRiverkeeper Program rubbish collection teams provide broad-scale removal of rubbish from the river’s foreshores, creeks and tributaries. Member councils identify rubbish ‘hotspots’ on the river for inclusion in the Riverkeeper workplan. The Riverkeeper Program services the GRCCC’s member councils who have a collective responsibility for the health of the Georges River catchment.

Rubbish comes in many forms, each causing a unique danger to aquatic habitat. Studies have shown that plastics account for over 60% of debris found within mangrove communities,
and over 90% of debris found in marine systems. Plastics cause harm when ingested by seabirds, marine mammals and fish species. Plastics can potentially introduce invasive species by allowing ‘passengers’ to adhere to drifting bags and debris.
HOW RUBBISH COLLECTSThe accumulation and occurrence of rubbish on foreshores depends on a variety of factors. Tidal influence, land form, vegetation type, weather conditions, bank steepness and condition of foreshores, and the buoyancy of rubbish all play a part in the collection of rubbish.
Plastics
Micro-rubbishMicro-rubbish is characterised by the smallest pieces of rubbish, no bigger than 15 mm, such as polystyrene, bottle tops, rubber and broken debris. Micro-rubbish is extremely harmful to aquatic animals and insects, and degrades foreshore and riverbed soils.
Most of the rubbish that makes its way through the conventional stormwater system into the river is caused by littering in urban areas.
Items of large rubbish typically found include car tyres and batteries, televisions, trolleys, furniture, mattresses, general building waste, milk crates and polystrene packaging.
