Not just the Southern Oscillation
From [URBNRM] Network Update 22nd July 2006
The Southern Oscillation, the weather phenomenon with El Niño and La Niña episodes linked to climate in eastern Australia, is relatively well known. However, the Southern Oscillation is not our only significant weather oscillation. The “Pacific Decadal Oscillation” (PDO) is long lived Southern Oscillation-like pattern of Pacific climate variability. While the two climate oscillations have similar spatial climate fingerprints, they have very different behavior in time. Southern Oscillation events typically persist for only up to several years, whereas PDO events persist for 20-30 years. Interestingly, it has been found that the PDO had featured most strongly than at least some parts of south-eastern Australia.
Independent studies find evidence for just two full PDO cycles in the past century: ‘cool’ PDO events prevailed form 1890-1924 and again from 1947-1976, while ‘warm’ PDO events dominated from 1925-1946 and from 1977 through to at least the mid-1990’s. The 1947-1976 ‘cool’ event appears to be associated with wetter decades in eastern Australia, and the ‘warm’ events since 1977 associated with relatively dry decades. The 1947-1976 wetter decades are the time that many Australians remember as “the normal wet season we use to have”, and also the time when much of our urban water supply dam infrastructure was planned or constructed.

Toad Muster Nets 5000+
From Australian Land Care
Australian Farm Journal
June 2006
http://www.farmonline.com.au/farmmags/australianlandcare/publication.aspx
Brunswick Valley Landcare and Byron Shire Council last March joined forces to hold their inaugural toad muster of the Far North Coast of NSW. The evening raised awareness of the impact cane toads (bufo marinus)were having on the environment, and educated people on the way to identify and control the pest. Community members were encouraged to bing in live toads. Prizes were offered for the most toads and the heaviest toad collected. Cane toads are believed to have been brought to Byron Bay in the 1960's and have been increasing in number since then. They began heading south and north-west from North Queensland after being released in a misguided attempt to rid canefields of the cane beetle in the 1930's. Since then, the poisonous and incredibly adaptive amphinbians have spread though out Queensland and the Northern Territory. The current southern limit of the Taods manace is around Yamba with isolated population around Port Macquarie. "The cane toad poses a serious threat to our local biodiversity ." Byron Shire Council's biodiversity extension officer,Wendy Neilan, says. "Most native animals that normally eat frogs die when they attempt to eat cane toads." Organisers of the toad muster were overwhelmed by it's success as about 60 people turned up for the event to deliver thousands of live toads in buckets, crates and boxes. Brunswick Catchment Landcare support officer, Dave Rawlins, says the final tally of the night came to 5890 adult and juvenile toads, with a combined weight of 77 kilograms. "We did not know how many toads or people would come along to the muster and this was a test to see if the community supported the concept," Rawlins says. "Feedback from the participants was that this should become a regular event . "We are now looking at ways to expand the muster so it can be in more locations and over a longer period of time to maximise the collecting and controlling of the toads." Prize for the biggest tally went to Alan Rayward and his granddaughter, Stacey Devine, for bringing in more than 3000 specimens, including juveniles. "I'd like to see Byron Shire free of cane toads," Reyward says. "I know what the fauna was like before. We used to have black bitterns and many more frogs. This year the toad population is totally out of control with the return of a real wet season." Brunswick Valley Landcare is also investigating the viability of cane toads traps. Devices bring used in Byron Shire are a mixture of components produced locally and by Frog Watch in the NT. These use a light to attract insects, which entice the cane toad through a one-way doors. Local landcarer, Greg McDonald, is using his electrical and engineering skills to design remote traps that can be powered by rechargeable batteries (either on the trap with solar panels or at home from mains electricity). McDonald is developing ingenious ways to reduce the light output but still attract insects. This would mean traps could run from smaller, cheaper solar panels, or if just using mains power, rechargeable batteries would last longer.

Sustainable Designers of the Future
From Waste Streams June/July 2006
http://www.wastestreams.com.au/
The 2006 Australian Design Award-Dyson Student Award winners were announced on 19th May 2006.
Among the top 12 finalists was a dishwasher uses less water than hand washing and no detergent and a device that is intended to provide a reliable supply of clean water in developing countries. Included in the 21 short listed finalists was a grey water recycling system designed to reduce household water consumption. The Gold award was won by University of New South Wales student Tricia Ho for her ergonomically designed violin; a silver award went to University of South Australia student, Liam Fudali for his Flex – an improved harmless design for self-contained breathing apparatus; and Julie Frost’s water purifier took out the bronze award.
Steam Dishwasher
The ‘Swash’ dishwasher, designed by University of Technology Sydney student Alexandra Gilmour, Combines nanotechnology and high temperature steam and is claimed to be the first sustainable, self-sufficient dishwashing solution that sterilizes and reduces water usage. The unit won’t need to be connected to mains water - it wi8ll use only 6 L of water stored in an internal reservoir to do its cleaning, The water will be filtered, purified and returned to the reservoir with minimal loss, so the same water can be reused several times before it has to be toped up. “My aim was to develop a new cleaning method an innovative solution to existing models that would reduce water usage/wastage and provide a hygienically clean result. This was achieved by using high temperature steam as a cleaning agent which eliminates detergent use and nanotechnology for continual water filtration for reuse,” Alexandra said. “I wanted something that could be bought off the shelf like a microwave and all you had to do was take it home, find some bench space, plug it in and fill it with water.” She said.
Solar Water Purifier
Julie Frost’s water purifier design, Mvura is a household water purifier intended for use in developing countries such as Africa. Designed to be carried on the head the device can transport, purify, then store and dispense the water, reducing the risk of recontamination. This multi-function capability is possible because of the way it is designed. Solar energy is used in the purification pasteurisation process which requires the water to be heated to 65c. This is sufficient to kill all common bacteria. With its larger flat shape, the purifier maximises the potential surface area exposed to the sun rays combined with a minimum depth of water for the rays to pass through. It is insulated on the top by an air gap and on the bottom by a foam casing. Together these serve to create a product that takes less then two hours to heat 15 L of water to the required temperature. A wax melts at 65c to indicate that the water is pure. The purifier has a curved base which fits the profile of the head. The wide lip around the top gives the hand a good grip when lifting the container onto the head and handles incorporate into the band aid carrying. When the container is closed and filled with water, there will be no room for the water to ‘slosh’ about.
Grey Water Recycling System
Mandy Burns developed a Dual Wastewater Shower Diverter the consists of an interior grate which is located on the shower floor and allows residents to divert shower wastewater into separate locations through out their homes, for onsite grey water recycling, such as irrigation, laundry washing and toilet flushing.
Other Award finalists included : Wheeled Mobility for paraplegics who lived independently ; Medi-Vest ; Mardi; Water Pod; Kiss Tile (keep it simple solar tile); an ovarian cancer screening device; Mantra Kitesurfing Bar; and Insulaid.
“The Australian Design Award-Dyson Student Award is an incredible program that puts student talents under the spotlight and provides a bridge from academia to industry,” says Stephanie Watson, Manager of the Australian Design Awards. The students have produced some innovative products the incorporate sustainable design features and offer benefits to the end user.

Drown-proof Tank
From Waste Streams June/July 2006
http://www.wastestreams.com.au/
Action talks' underwater tank design has a 152mm hole as it's largest entry point whereas the average tank on the market has an inspection hole of 400mm. The tank was designed to prevent drowning in the tank after an 11-month evaluation of every underground rainwater tank in Australia. The above-ground tanks are also drown-proofed with a strainer screwed in place, and under that is an internal flush diverter. If a child manages to kick a hole in the strainer, access to water is barred by the diverter.

Grey Water Treatment Technology
From Waste Streams June/July 2006
http://www.wastestreams.com.au/
The Aqua Reviva system is designed to treat household grey water without the need to intrusive excavation. Grey water from the bathroom and laundry can be treated and recycled to health regulations standards so that it can be reused in washing machines, toilets, as well as for use in the garden and for washing for the car. Treated water can be stored for an unlimited period of time, unlike diversion systems where the water must be used within 24 hours. The system generates water that is Class A standard and also removes other harmful nutrients. The system has the protential to save an average home 500L of water per day. This, applied to the 125,000 new homes built around Australia this year, saves 62 million letres of water per day or the equivalent of a swimming pool stretching from Melbourne to Darwin. This also entails an energy saving by reducing the need for sewerage processing. The system uses a naturally occurring biological process supported by a light bromine disinfection stage. The system incorporates automatic overflows to sewer. The system is self-contained, involves no maintenance or adjustments from the householder and should anything not work exactly as planned then it automatically diverts all water to sewer with out any personal intervention. The system uses a 12v power source that can be operated usinf solar power is desired. The installation is not intrusive and has the option to be fitted under a house or deck.

Turning Wastewater into Watts
From Waste Streams June/July 2006
http://www.wastestreams.com.au/
UQ Research uses microbial fuels cells
Your dirty dishwater could soon be providing the electricity to power wastewater treatment plants if University of Queensland researchers have their way. The UQ team has developed a technique that removes pollutants and organic compounds from wastewater and turns them into environmentally friendly electricity. The researchers will receive $1,300,000 in funding over five years as part of the Australian Research Council's Discovery Projects Grants. PhD student Freguia from the University's Advanced Wastewater Management Centre (AWMC) said there was still more research to be carried out before the power source could be commercialised. "Our experiments have shown that the chemical energy contained in the organic matter present in wastewater can be recovered as electricity by using microbial fuel cells," he said. Microbial fuel cells are similar to common chemical fuel cells but use microbes as catalysts and can therefore untilise wastewater pollutants for energy production rather then a chemical fuel such as hydro hydrogen or methane. Mr Freguia is currently completing his PhD at UQ examining power production from wastewater using micobial fuel cells."In micobial fuel cells the electron donor is an organic substrate and bacteria are used as catalysts for it oxidation to carbon dioxide," he said. AWMC director Professor Jurg Keller said the cells should be used to generate renewable electricity to power wastewater treatment plants while at the same time removing the pollutants. "You should be able to generate sufficient energy from pollutants in wastewater to run the entire treatment process," Professor Keller said. "The technology could significantly reduce the operating cost of wastewater treatment plants." Not only is the new power source cheap and readily available, it is also environmentally friendly. "All of our power that is produced is from renewable sources - the pollutants is the wastewater," Professor Keller said. "It's all happening in a thin biofilm, a sort of slime layer on the electrode where bacteria are growing and directly producing electrical current." Professor Keller and Mr Freguia are continuing their research in to the microbial fuel cells and expect there to be early applications arising from the technology with in five years.

Saving the River Red Gums
From Waste Streams June/July 2006
http://www.wastestreams.com.au/
Coats Shorco assists in water management project
With drought gripping much of Australia, even hardy natives species have fallen victim to it's effects. Among them, the majestic River Reg Gums that line the dry creek beds, or anabranches, adjoining the Murry River. A unique and beatiful part of the Murry landscape, the River Red Gumshad become increaingly stresses by dwinding water supplies in the Murry River floodplain, with large numbers dying as a result. In an effort to save them, the Department od Sustainability and Environment commenced a successful Emergency Watering Program in 2004 to provide crrucial water supplies to the gums lining the anabranches during the spring and autumn seasons. Of great assistants in the succes of the task has been Coates Shorco. Having successfully tendered for the Living Murry Project, Simon Panther, pump manager of Coates Shorco Victoria, and his team set about specifically engineering a solution that most effectively and economically met the requirements of this important task. Using predominanty 300mm high-flow diesel pumps, with much equipment built or modified specifically for the project, Coates Shorco will have assisted in pumping approximently 7.5 billion litres of water to the anabranches by june 2006. While providing equipment, sevice, mantenance and monitoring of flow, Coates Shorco has also ensured the environmental safety of the work using its bunding to contain fuel and oil around the pump. As a result of the efforts, the future now looks much brighter for these glorious Australian giants.

School's Sewage Bills Flushed
From Waste Streams June/July 2006
http://www.wastestreams.com.au/
KEWT wastewater treatment systems installed
A Queensland reseacher's wastewater treatment invention has been installed at Greenbank State School, on the outskirts of Brisbane. The KEWT (Kele Effluent Wastewater Treatment) system, developed by Ben Kele from CQU in Rockhampton and commercialised by GBG Project Management Pty Ltd, will treat and reuse the wastewater from over 1000 students and staff at a site cost of $340,000. Not bad considering the school has been paying $80,000 a year to pump out all of its sewage. The site will have remote monitoring and will provide recycled water for oval irrigation and cabinet timber plantation. Glenbank State School is believed to be the first Australian school to be fitted with a 'green' wastewater treatment system. The site was recently opened by the Minister for Education, Rod Welford. Mr Welford said he was positive the KEWT system was the "way of the future". The system will also be used as an education tool for students at the school to learn about water cycle and sustainable technologies. It will also be used as a site for Mr Kele's PhD research. KEWT is an unique system for the treatment of wastewater and effluent. It uses a mixture of biological treatment systems and reuses effluent through a self -contained recirculatory form of sub-surface irrigation. Me Kele is currently working on a number of other projects including sustainable housing development, holistic water management frameworks for local governments and biological firltration projects.

Technology for the reduction of filterable reactive phosphorous (FRP)
From Waste Streams - Apr/May 2006
www.WasteStreams.com.au
Technology for the reduction of filterable reactive phosphorous (FRP)
During the last decade, the significance of FRP reduction from the water column and the sediment P release control in preventing algal blooms has been recognised. In order to control the P level in water bodies, a number of chemical methods, such as alum or ferric chloride, have been used over the last few decades. However, many scientific studies have demonstrated significant limitations associated with these methods, including the re-release of the sorbed P when physiochemical characteristics of the water body, such as its alkalinity or redox conditions, are changed. In addition, key water quality parameters, such as the ph and conductivity of the water body, can also be affected.
Given the role of the FRP in phytoplankton activity and the limitations of the currently used chemical methods, there is a great need for a technology that can reduce the FRP concentration of the water column and prevent the release of the sediment P under a wide range of chemical conditions (ph, salinity and redox), without affecting the key water quality parameters. The need has been met by a modified bentonite product known as Phoslock.
It removes FRP effectively as it descends through a water column. As it settles, it forms a capping on th e bottom sediment preventing any further release of FRP into the water column.
The product has been demonstrated to have a rapid FRP uptake kinetic, removing 90% of it within the first four hours. In addition, it is shown to operate within a wide ph range (5-11), without any significant change to the ph of the water body.
It performs efficiently in a wide range of water bodies, ranging from natural waterways, aquaculture and a variety of waste waters such as sewage treatment holding lagoons, farm dams, poultry, dairy and piggeries. Furthermore, the removal of arsenate , selenate and molybdate has also been demonstrated.

Technology for the reduction of filterable reactive phosphorous (FRP)
During the last decade, the significance of FRP reduction from the water column and the sediment P release control in preventing algal blooms has been recognised. In order to control the P level in water bodies, a number of chemical methods, such as alum or ferric chloride, have been used over the last few decades. However, many scientific studies have demonstrated significant limitations associated with these methods, including the re-release of the sorbed P when physiochemical characteristics of the water body, such as its alkalinity or redox conditions, are changed. In addition, key water quality parameters, such as the ph and conductivity of the water body, can also be affected.

Rainwater bladder tanks

Rainwater bladder tanks
Rainwater bladders are flexible water tanks that can fit under a house. The bladders are claimed to be able to capture up to 500% more water than a standard tank system.
The Rain Reviva system is suitable for sites where a water tank won't fit because of lack of space or where access is difficult.
A traditional water tank will only capture water from one side of the roof, whereas a bladder installed under the house uses the entire catchment surface area of the roof, which means that more rainwater is diverted into the tank.
In addition to the bladder-like tank, the system incorporates an 'inlet diversion' - a 'swing arm' system - that efficiently diverts the rainwater from each downpipe into the water sacs. A pump system then allows the water to be reticulated to a range of devices from the garden hose and the pool to sprinkling systems, and even the washing machine and dishwasher.

Converting wastewater salt into cleaning compound
Dairy companies are closing the recycling
Researchers involved with the Dairy Australia-funded project at Food Science Australia in Sydney are only months away from discovering a way to recycle the salty water that forms in waste milk after the solids have separated from the liquid.
According to Dairy Australia's head of resource management and technology, Neil van Buuren, the researchers are exploring a simple concept that could deliver significant environmental benefits.
"As well as being environmentally responsible, dairy manufacturers would save thousands of dollars by recycling wastewater and reducing the amount of salt in effluent," Mr van Buuren said.
"The salt would be used to make alkaline and acidic cleaning compounds, which would also reduce the need to purchase concentrated cleaners.
"While this discovery would have immediate benefits for dairy manufacturers, dairy farmers should be able to use the same technology on their farms and get the same benefits," Mr van Buuren said.
Researchers in the US have also discovered a new way to clean and disinfect milking equipment using electrolysed oxidising water.
This water is created when the electric current flowing through two electrodes - immersed in a weak salt solution and separated by a membrane - produces an alkaline and an acidic solution.
"The US researchers and Australian researchers have used the same science, but with a different raw produce," Mr van Buuren said.
"The Australian researchers are trying to recycle a waste product, not create a new salt solution," he said.
This project is part of the Closing the Loop initiative which is funded by Dairy Australia and The Geoffrey Gardiner Dairy Foundation. It aims to cut the environmental footprint of Australia's dairy factories. The third research partner is the Department of Primary Industries.

Water reclamation plant unveiled in Noosa
Econova techology treats water like gold
Petrac has unveiled its Queensland designed water reclaimation plant on the Noosa North Shore. With the message that water can be treated like gold, the plant takes good care of delicate environments tht exist in the lowlands of the Noosa North Shore, using the latest membrane technology.
Fewer nutrients and pollutants will flow from the site with the wastewater treatment plant turning out a previously unreachable Grade A + standard.
Petrac's director of development, John /campbell said the $1.2 million installation represented a significant improvement on the wastewater system that the company inherited when it bought the site.
"We worked with the Environmental Protection Agency and our environmental engineers Cardno to identify how we could sustainably reuse wastewater while meeting stringent environmental standards," he said.
The contract involves EcoNova providing the technology that can reclaim wastewater and treat it to a standard surpassing EPA guidelines.
Cardno's project engineer, Michael
chessells, said potable water consumption will be reduced by 10-15% by watering lawns with reclaimed water and because the sewage treatment plant was replaced with the water reclamation plant.

New dams proposed (Media Release)

Subject: BILLION DOLLAR FUND TO TACKLE CLIMATE CHANGE
Premier of Queensland
The Honourable Peter Beattie

BILLION DOLLAR FUND TO TACKLE CLIMATE CHANGE
Two new dams and two new weir projects will be built under a new fund worth more than
$1 Billion to be established by the Queensland Government.
Premier Peter Beattie and Deputy Premier and Treasurer Anna Bligh today announced the State Government would legislate to create the Queensland Future Growth Fund to help meet the challenges of climate change and the continued economic development of the SmartState.
Mr Beattie said the fund would be financed from the sale of Sun Retail - comprising the retail business arm of Energex - and the contestable elements of Ergon Retail.
"This massive new fund will position the SmartState to tackle the challenges of climate change through a raft of new innovative technology and infrastructure projects," Mr Beattie said.
"Climate change is a worldwide issue but the impacts can be felt right here in our own backyard.
"Queensland will get drier and hotter. Changes in weather patterns have affected our environment - most notably our water supplies.
"In addition, we must tackle issues such as greenhouse gas emissions and their role in climate change."
Mr Beattie said all details of the new Fund will be released when the sale of the retail business had been concluded and the final price determined over the next twelve months.
He said this was expected to be in excess of $1 Billion.
"As a priority under the Fund we will allocate approximately $200 - $300 million to help accelerate the building of two new dams and two new weir projects," Mr Beattie said.
"Subject to Commonwealth cooperation we now expect these projects to be completed by the end of 2011.
"Together they are expected to deliver up to an extra 235,000 megalitres per annum - this is equivalent to the approximate capacity of more than three new Hinze Dams.
"We will build a major new dam on the Mary River in the Gympie region and bring forward the construction of the promised new dam proposed for the upper reaches of the Logan River to help support burgeoning population growth in south east Queensland
"As part of this process we will re-examine the existing proposal for the Wyaralong Dam site as compared to a new site which has been identified at TilleysBridge near Rathdowney. A detailed investigation, including geotechnical works will be carried out to determine which site will deliver the best yield.
"On the FitzroyRiver in Central Queensland we will raise the Eden Bann weir and build a new weir at Rookwood.
"These two projects alone are expected to deliver up to 86,000 megalitres per annum for future growth in Rockhampton, Yeppoon and Gladstone as well as help fuel our booming coal export and minerals industries."
Ms Bligh said $300 million from the Queensland Future Growth Fund would be allocated to support the continued sustainable development of clean coal technology.
"The rapid shifts in our climate are a clear warning Queensland must work to actively manage our strong position in the global economy while at the same time minimising the impact on the environment," Ms Bligh said.
"Already our Government is involved in a world leading program of research, development and promotion of alternative energy sources.
"We are focused on ensuring our levels of greenhouse gas emissions are kept to an absolute minimum while still meeting the growing demand for energy from our booming economy and population.
"Under the Fund we will allocate $300 million to help this program take a giant leap forward.
"The money will be dedicated to the future development of clean coal technology.
"It will complement a $300 million industry fund set up by consortium Coal21 which includes BHP Billition, Rio Tinto, XStrata and Anglo as well the $500 million Low Emission Technology Demonstration Fund established by the Commonwealth Government.
"We will work together on clean coal technology that will help guarantee the viability of the coal industry into the future while cutting pollution and emissions associated for the use of this resource in power generation."
Ms Bligh said other projects in the Fund would be determined once the sale process had been completed, however sufficient proceeds would be reinvested in GOC commercial infrastructure projects to ensure the State suffers no net loss of the income presently derived from the two assets.
She said that while other States had applied the proceeds of similar sales to paying off debt, the Government's history of prudent financial management and unique net debt position meant it was able to invest the funds in the future growth of the State.

Miriam Vale Toadbusters
Year 2/3 Toadbusters – We did it!!
(Kathryn Apel)
The Year 2/3 Toadbusters night was a resounding success. Conservative estimates put the number of toads 'froze' at 1000.
After a social sausage sizzle, the Year 2/3 students made an entertaining and informative rendition of the poem, ‘Bufo Marinus – What Is It?’ A superb effort!
We then welcomed Anna Hitchcock who joined us from the Gladstone Toadbusters group. Anna shared her expertise - and a lot of safety equipment. She also bagged quite a few Bufos!
The competitive side of the evening was fraught with difficulties, but this didn’t dint enthusiasm. The Browning/Lavia team bagged the ‘Loads of Toads’ award, producing 9 bags full! ‘ Catch of the Day’ was also awarded to this group – mainly because other competitors were reluctant to delve into bags and produce their whoppers. All in fun! Michelle Dahl convincingly won the ‘Warts and Wails’ award for the most shrieks and squeaks.
Though parental expectations for a ‘fun’ night perhaps weren’t that high, wide smiles and shared laughter confirmed the success of the evening. A huge thank-you to all families who turned up in support! Thanks also to Paul and Felix for wielding the BBQ tongs so proficiently.

The Ten Thousandth Toad!
These are pictures of the ten thousandth (10 000) toad caught at the Duckponds. It has taken Toadbusters five years and many volunteer hours to reach this amazing total. This little star has gone to the big duckpond in the sky like his 9 999 friends.

Senate Rural and Regional Affairs and Transport References Committee
Inquiry into Water Policy Initiatives
The Senate Rural and Regional Affairs and Transport References Committee is conducting an inquiry into the impact on rural water usage of recent water policy initiatives and the possible role for Commonwealth agencies. The terms of reference are:
the development of water property titles;
methods of protection for rivers and aquifers;
farming innovation;
monitoring drought and predicting farm water demand; and
the implications for agriculture of predicted changes in patterns of precipitation and temperature.
The Committee is interested in exploring the state and territories policies underpinning the National Water Initiative, any assistance that can be provided by Commonwealth government agencies to develop and roll out these policies and the implications for rural land use of these policies. In this context it will also examine the potential for farming innovation. The Committee will also consider work being conducted on monitoring drought and the state of aquifers, the development of farm water assessment systems and any implications for agriculture of predicted changes in rainfall patterns and temperature.
The Committee invites you to make a submission addressing all or some of these matters, and would appreciate submissions to be sent by 1 February 2006. If you know of someone else who maybe interested in making a submission to the committee, please pass this letter on.
Information on this inquiry can be found at http://www.aph.gov.au/Senate/committee/rrat_ctte/rural_water/index.htm

Bushland-friendly gardens
From Weedwatch, Vol 2 November 2005
Newsletter of the Cooperative Research Centre for Australian Weed Management
"Bushland-friendly gardens: weed-free wonderlands
The Weeds CRC has developed a new website area, named Bushland-friendly gardens, that suggests which plants should be avoided in our gardens.While there are many organisations that currently present weed information in a myriad of formats, we felt that it was just too difficult for many gardeners and landscapers to find out this information on a regional basis. Our website provides a 'one-stop shop' in the form of a 'clickable' map that will generate two lists of commonly available garden plants that should be avoided in your chosen region.We have started at a relatively broad scale by subdividing the states into a total of 22 regions based on a classification of climatic zones already widely used in the horticultural industry. Reviewing more than 100 lists of problem plants prepared by a range of groups and bodies around Australia, we made the assumption that the more lists on which a plant appears, the more it is likely to cause impact within any region. Therefore, when clicking on a particular region of the map provided, two prioritised lists are generated. Where a plant species appeared three or more times in lists for a region, it was placed into the 'serious environmental weeds' list. We recommend that plants on this list are removed as soon as possible. If a plant species appeared twice, it was placed on the 'environmental weeds to avoid' list, in which case it should not be planted, or at least should be managed with great care.We believe that the final weeds lists for each region are a fair representation of the potential and actual impacts for each species.While the site does not suggets alternative species to plant, it will point (again on a regional basis) to reference documents and web information that includes such advice.To give your feedback please use the facility provided on the website.
