Consultation on the Draft Greater Sydney Regional Strategic Weed Management Plan

Dear Bushcare Volunteers

Greater Sydney Regional Weed Committee is very keen to hear from as many people as possible on the plan so we hope you can make one of the information sessions.

INVITATION TO A PUBLIC CONSULTATION FORUM on the Draft Greater Sydney Regional Strategic Weed Management Plan

The draft Greater Sydney Regional Strategic Weeds Management Plan (GSRSWMP) will be released for public consultation on 8 February 2017. The plan has been developed as part of the NSW Government’s Biosecurity reform process in response to the Natural Resources Commission’s review which identified the need for a more coordinated approach to managing weeds.

It is estimated weeds cost the NSW agricultural industry about $4.3 billion every year. Weeds also have serious implications on our lifestyles and the natural environment. Native biodiversity in particular has suffered declines in the distribution of many species as a result of invasive plants.

The GSRSWMP will provide the framework for improved management of weeds on both public and private lands by guiding investment to achieve the greatest outcomes in prevention, eradication and containment.

The draft plan was developed by the Greater Sydney Regional Weed Committee in partnership with Local Control Authorities (i.e. local governments), NSW Department of Primary Industries, National Parks and Wildlife Service, environmental interests (i.e. Nature Conservation Council), Landcare, NSW Farmers Association, Nursery and Garden Industry Association and Aboriginal and public land managers.

The Plan will now be made available for public consultation for feedback before being finalised.  As part of the consultation process, Greater Sydney Local Land Services and the four subregional weed committees will host five public forums across the region. The purpose of the forums is to explain the contents and impacts of the draft plan, respond to questions and assist anyone who is considering commenting on the draft plan.

A Forum will be held in Penrith at the Cambridge Park Community Hall 97 Oxford St Cambridge Park on Tuesday 7 February from 5pm -7pm.

To register your interest in attending please email  admin.greatersydney@lls.nsw.gov.au  or phone Greater Sydney Local Land Services on 4724 2100

The Draft Greater Sydney Regional Strategic Weed Management Plan and supporting information is available at  www.lls.nsw.gov.au/greatersydney  from the 8th February 2017.  If a copy is required before this please email admin.greatersydney@lls.nsw.gov.au

The closing date for submissions is 8 March 2017.

Another pest to tackle : Arion ater, the European Black Slug

A single sample of this invasive European slug was recently found at the South Lawson Park Bushcare site, and the suspected identity was confirmed by Michael Shea at the Australian Museum. Unfortunately, it would seem that this slug is widespread in some, but not all parts of the upper Blue Mountains (and at selected sites in Victoria and SA) and may be spreading into the middle mountains area.

The adult form of this slug is deep black, with some minor individual variations (white, dark brown). It has no shell, and numerous tubercles, similar to raised mini spines, are clearly visible on its back. The slug is 10-15 cms long. According to the Australian Museum, there are no confusing native species. The black colour makes it quite distinctive. They have no known natural predators in Australia.

Collection and disposal by bushcare volunteers may be effective in slowing and perhaps stopping their spread into unaffected areas, and doing this can slow down their overall acclimatisation process. The impact of this slug on native fauna is unknown, so limiting their numbers and spread may minimise any adverse impacts whilst research into this aspect of the problem is being conducted and can be applied.

The mucus of this slug is particularly thick and unpleasant so the use of gloves is recommended. Please try to dispatch them in a humane manner, such as in a lidded container with a small amount of beer, or by freezing. Snail bait placed in the open can harm native wildlife.

Record your sightings at https://www.ala.org.au, the Atlas of Living Australia or via the on-line reporting tool on the Local Land Services Wildlife Sighting Portal at:  http://greatersydney.lls.nsw.gov.au/resource-hub/web-tools. You can also enter the portal directly which will bring up a map of the records to date.

Peter Ridgeway at Greater Sydney Local Land Services is aware of their presence in the Blue Mountains and hopes to engage in an education program with local nurseries. Museum Victoria at https://www.museumvictoria.com.au can also help with further information.

Thanks for considering this issue. Peter Ardill, South Lawson Park Bushcare.
