Botany Bay and Catchment Alliance

THESE are the shocking images that have provoked an overwhelming response of disgust from our readers.

Tonnes of waste from engines to filing cabinets and thousands of plastic bottles lines the banks of the Cooks River through Canterbury, Campsie, Hurlstone Park and Earlwood.

The Express visited three sites along this short stretch of river at Picken Oval, Croydon Park; Lees Park, Ashbury and the renowned “PET cemetery’’ of Tasker Park, Canterbury, where thousands of plastic bottles have been collected in the mangroves.

The litter is an environmental shame but it reveals only what is visible to the naked eye.

The invisible threat of fecal contamination and dangerous levels of E.coli is the river’s biggest enemy.

Test results released by the Cooks River Valley Association reveal E.coli levels 60 times higher than those acceptable for human contact or swimming, and nine times higher than acceptable for secondary contact, such as boating. (more…)

The following figures were given on a daily basis for beaches within the Botany Bay and Georges River for the three weeks commencing Sunday 22/01/2012. The pollution is said to be caused by stormwater overflow from various land sources. A high percentage is from sewerage outflows.

* Rainfall data has been used to predict the likelihood of bacterial contamination at swimming sites in Botany Bay and lower Georges River. When pollution is likely, swimmers may be at increased risk of contracting illness and swimming at these sites should be avoided.

GEORGES RIVER

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 Scheme, then east until it reaches Botany Bay. It was an important focal point for Aboriginal life and culture in the southern Sydney region, offering both food, transport and dreamtime links. The early 1800′s saw European settlers migrating to areas along the river and it became increasingly important as a transport route. There is some evidence of agriculture associated with early settlement, but this was limited by the ruggedness of the landscape and limited suitability for farming. Widespread clearing and expansion of urban development after WWII changed the landscape of the river and impacted on water quality. The prevailing view at the time was that intertidal areas (wetlands and swamps) were wastelands, unsightly and a threat to public health. Removing mangroves made it easier to dump waste to raise the ground to a “healthy” level suitable for sports grounds. Opposition to this devastation lead to the establishment of O.F.F. and other environmental groups from the 1950s. The NSW National Parks and

Wildlife Service (NPWS) was established in 1967 and the Georges River Combined Councils Committee [GRCCC] in the 1970s. www.georgesriver.org.au/

NATIVE VEGETATION – GEORGES RIVER N P

Georges River National Park (NP) is a small urban reserve of over 500 hectares with fifteen disconnected portions of mostly vegetated land that lie north and south of the river between Sandy Point and Salt Pan Creek, Lugarno. North of the river, the Park lies within an urban-residential setting.

The largest portion of the reserve is on the southern banks between Sandy Point and Mill Creek, and its southern boundary links to the Woronora Plateau. The first declaration of the Georges River reserve was in 1962 responding to dramatic human induced changes to the catchment area. It was designated a national Park in 1992.

Some remarkably undisturbed examples of the original environments remain. However, despite its proximity to a large urban population, the native vegetation had not been the focus of a detailed vegetation mapping study. NPWS saw the need for such a study with the results to be added to a recently completed map of native vegetation across the Sydney Catchment Area (SMCMA). This study h a s  n o w  b e e n  c o m p l e t e d . T h e first draft of its report was published in November; the final report will be out soon. www.environment.nsw.gov.au/parkmanagement/

DHARAWAL STATE CONSERVATION AREA

“The Bulli Seam Operations, BHP’S 30 year plan to longwall coalmine in the Appin to Wollondilly region, was approved 3 days before Christmas. The plan has been modified from its original proposal and now excludes any mining activity in more than 98% of the Area. (more…)

The following gleanings are from recent Oatley Faura and Fauna Society Newsletters:-

CAMPHOR LAUREL: A PEST TREE

It was introduced to Australia as an ornamental species about 1822 and established in the Sydney Botanic Gardens in 1854. Its value as an ornamental tree was actively promoted in municipal parks, gardens and school grounds. 10 years ago, OFF News noted that this tree was a pest, 

invading natural habitats all along the coast, with its root system damaging pipes, fences, foundations, and preventing the growth of other species. It reported that Kew Gardens in U.K. found the roots of camphor laurels to be covered with tiny oil exudation glands that seasonally pump toxins into the soil and water courses, and impact on native wildlife. Surprisingly still well regarded by some, camphor laurel is now a declared noxious weed, but not in all localgovernment areas.

BIRDS IN OATLEY PARK

The Park provides a sanctuary for many species of birds, some of which nest within its boundaries Others simply use the park and itstidal boundaries as part of their wider search for food and shelter, returning regularly to the park, but nesting elsewhere. It is difficult to say exactly how many bird species can be found within the park at any one time; numbers vary depending on the season and availability of food. 

BIRDS OF OATLEY PARK

In a recent email to OFF, Warren Mallard made some interesting comments on the birds he remembers from Oatley Park in the 1950s. He notes, “Yellow-tufted Honeyeaters were the most prevalent, and there were colonies of Dusky Wood Swallows nesting at the end of Lime Kiln Bay. Grey Thrushes also nested in the area. A White-breasted Sea Eagle nested for a number of years in a large Angophora costata   at the end of Lime Kiln Bay,but left once Peakhurst houses sprang up. Southern Yellow Robins were common, nesting with Silvereyes in the Melaleuca forest of Lime Kiln Bay. There were two species of Quail also in the park, and there were no Sulphur-crested Cockatoos, Noisy Miners, Rainbow Lorikeets, or Scaly-breasted Lorikeets. ”Warren’s notes open up the question of how different is the birdlife now. Official lists are from about 1975 basedon much earlier observations. One list contains 114 species; another more than 145, so there is a need for a new list for Oatley Park, Lime Kiln Bay, and Oatley Heights Park, noting behaviour and locations. It will take some time to complete, as a number of birds are summer visitors or only vagrants. The completed list will then go on the OFF website.

PROTECT OUR NATIVE ANIMALS IN THE BUSH

Stay on walking tracks in bushland.

• Admire wild flowers and plants – do not pick them.
• Leave natural features such as fallen timber on the ground.
• Leave yabbies, tadpoles, and water bugs in the creeks.
• Remove all your rubbish from the bush.
• Use your compost bin for garden green waste.
• Walk, rather than ride a trail bike.
• Keep equipment and boots clean. Spray with 70/30 mix of metho & water to stop spreading the fungal disease , Phytophthora
• Keep pets at home, particularly cats, and especially at night.

RECYCLING FOOD SCRAPS

Food scraps such as banana peels, apple cores, vegetable trimmings, bones, eggshells, and pizza crust are a wasted resource in landfill. As they decompose, they generate methane, but when composted, they produce oxygen, valuable to soil and plant health. They can now be safely collected and processed, and a growing number of municipalities provide special food scrap bins.
