In 2004 a second variety of bridal creeper, theWestern Cape form was identified growing ineight locations in south east South Australia andacross the border around the town of Nelson inVictoria. Field observations showed that the rustfungus was not attacking this form to the sameextent as common bridal creeper. This lead tograve concerns that we may be facing thereplacement of common bridal creeper by theWestern Cape form.A project was developed under the first round ofthe Federal Defeating the Weed Menace initiativeto map the density and growth range of theweed in this area. This task has now been successfullycompleted by Rural Solutions SouthAustralia.What was found was that the weed is far morewidespread than initially thought. In total, 224locations were mapped covering an area of approximately40ha in a range of habitats includingroad sides, pine forests and intact bushland.Encouragingly, no major infestations were foundoutside of the initial discovery area, indicatingthat this form is possibly confined to a singlegeographic area within Australia. A secondobservation made was that the weed appearsto be confined to areas within an annual rainfallof over 700mm in a 15 km wide band along thecoast.Some troubling findings were that the WesternCape form did not die back as quickly as thecommon form. In some areas, particularly innative vegetation, it was still green and coveredin fruit in February. In addition this form is a prolificseeder with huge amounts of seedlings beingrecorded germinating under mature plants.The infestation appears to be in its early invasionstage. Careful planning and prompt action overthe next few years will see this weed containedto small, manageable areas, with a view to eventualeradication.The draft report is available as a PDF down loadfrom:http://www.weeds.org.au/WoNS/bridalcreeper/Fig 5: Map of W Cape infestationsSource DWLBC


Figure 1: Asparagus scanden Photo: DWLBCThis close relative of bridal creeperis emerging as a problemweed in Western Australia, SouthAustralia and Tasmania. It has alsobeen recognised as invasive in NewSouth Wales and Victoria. Currentlycontained to smaller infestations ithas the potential to expand its rangerapidly. Like bridal creeper and bridalveil, A.scandens produces fruit attractiveto birds, rabbits and foxes. Italso shares the other weeds abilityto smother native vegetation and outcompete plants for water, light andnutrients. The fibrous root and tubermat prevents recruitment of nativevegetation. To date only TasmaniaFigure 2: Leaf and FruitPhoto : DWLBCFigure 3: Root MassPhoto : DWLBChas declared this weed. It remains a common gardenplant particularly on older properties. Infestations in remnantbushland would undoubtedly have been the resultof garden escapes but the careless dumping of gardenwaste on road sides and into the bush would have contributedto initial establishment of infestation sites. Earlyintervention will ensure that A. scandens does not becomeas prolific as bridal creeper. We do not have tolook far to see an exmple of the destructive nature ofthis weed. A.scandens is considered the worst Asparagusweed in New Zealand.An excellent control brochure for A. scandens has been produced by theWestern Australian Environmental Weeds Action Network.Down load a copy from :http://members.iinet.net.au/~ewan/pdf/A_scandens.pdfFigure 4: Potential Distribution of A. scandens(see brochure below)


The National Asparagus Weeds ManagementCommittee(NAWMC) has accepted the nominationof another community representative.Dean Overton joins the committee from KangarooIsland, South Australia. Dean has had manyyears experience in controlling bridal creeperand veil on the island and was instrumental,along with this wife Bev, in developing the “sporewater” rust redistribution technique. We lookforward to tapping into Dean’s experience.The committee is planning to conduct threeteleconferances through the year in addition toone face to face meeting in Adelaide towards theend of the year.The proceeding of the 2005 NationalAsparagus Weeds Workshop will bepublished in a special edition of the PlantProtection Quarterly in May 2006. Additionalcopies will be available from thebridal creeper coordinator, if you are nota subscriber to the publication.Part of any good management plan ishaving a map of where your target weed is.At present no comprehensive maps of the nationaldistribution, which include regional details,of bridal creeper or any of the other Asparagusweeds are available.So the questions goes out to all government andcommunity land managers. Do you have mapsof Asparagus weed infestations in your area ?At this point this is only an investigation into whatis available. Once we have established what’sout there and undertaken a feasibility study intotrying to marry the myriad of formats together willa final decision be made on developing a nationalmap. If you can help please forward any informationto Dennis Gannaway, National AsparagusWeeds Management Coordinator.Securingfunding is always a struggle,particularly when trying to find out what isavailable from State, Federal and private sources.To make things a little easier a tool has been developedby the Weeds of National SignificanceCoordinators. The project, lead by Hillary Cherry,resulted in the creation of a detailed spreadsheetcovering all aspects of available funding for 2006.This resource has been posted on the followingwebsite -http://www.weeds.org.au/weedfunding.htmclick on Summary of National Weed Funding Opportunities2006 to download the file. Any comments oradditional funding information would be gratefullyreceived. Comments can be sent DennisGannaway.The current major national funding opportunityis Envirofund Round 8. Details relating to eligibilitycriteria, relevant dates and applications formscan be found at the following website.www.nht.gov.au/envirofund/In the last issue of the newsletter referencewas made to A. scandens being a gardenescapee in and around Cape Town. This elicitedthe following response from Carien Kleinjan.“I read the bridal creeper newsletter with interest.Just one comment, the statements attributedto me concerning A. scandens in South Africadon’t really reflect the situation as I see ithere. I commented in my talk that A. scandensappears weedy in certain situations herein South Africa, a point also made by Dave leMaitre and referred to in the Reid and Timminspaper on A. scandens in New Zealand. However,these are indigenous plants growing withintheir natural habitat and in their natural range,they are not garden escapees. The fact thatthey appear to have the capacity to be weedyhere is of concern as it suggests that findingsuitable potential biological control agents maypresent a problem” Apologies Carien, we standcorrected.And finally the bridal creeper rust fungus hasturned up in New Zealand............. Wasn’t me !
