A number of seriously problematic weed types are evident within the Nangarin Estate, both on private and Community lands. Their ability to spread rapidly and distribute widely, due to their effective seed dispersal capabilities, are major reasons why residents need to act quickly to effectively eradicate these environmentally damaging weeds. Many of the weeds are toxic and suitable protective clothing and accessories should be used during treatment.
Below are links to pdf information sheets for the major weed types that may assist residents in both identifying and treating invasive weeds:
January 2023 marks the conclusion of the two year Nangarin Nature Corridor – ‘Cumberland Plain Woodland Restoration – Stage 2’ project assisted by the NSW Government through its Environmental Trust 2019-20 Restoration and Rehabilitation Grants.
The Project targeted areas of remnant Cumberland Plain Woodland (CPW) within the East-West nature corridor within the Nangarin Vineyard Estate, where the endemic biodiversity of the CPW was threatened by invasive Lantana (Lantana camara) and other weeds. Planned in three stages with site work commencing in February 2021, the project involved engaging a team of professional ‘Bush Regen.’ Contractors (Ecohort P/L) to work on the eastern corridor, while members of the Nangarin Landcare Group addressed areas of dense Lantana along the western corridor. Extensive periods of wet weather during the project posed challenges with planning and access to the steep slopes, coupled with the high rate of Lantana growth.
The most recent review of the Contractor sites showed a high success level in treating Lantana. A followup session in early January targeted any regrowth or areas missed in earlier sessions. Photo below shows reduction in Lantana in Contractor Stage 2 area:
Bridal Creeper (Asparagus asparagoides) is considered a major weed affecting NSW bushland areas, where it can smother native plants. It is classified as a ‘Weed of National Significance’.
It forms a thick mat, up to 100mm deep, comprising a mass of underground tubers from branching rhizomes which impede the root growth of other plants. Above the ground it has an attractive bright green, shiny ‘leaves’ (4–30 mm wide by 10-70 mm long) and its climbing stems readily attach to vertical support structures, like fences shrubs and trees. On the ground it forms a blanketing spread across garden beds smothering other plants.
Bridal Creeper is present in Nangarin and collectively we need to eradicate it from our residential Lots and bushland.
Chemical treatment is highly effective and needs to be done in the months of August through to the end of September, so it is important to treat any outbreaks now!

Always follow the herbicide manufacturers directions and use appropriate personal protection equipment when handling chemicals.
