Welcome

Landcare is a non-governmental community movement dedicated to preventing land degradation and achieving sustainable land management. It consists of a network of local volunteer groups of which there are over 1700 in New South Wales alone. Each group works to find local solutions to local problems such as salinity, soil degradation, animal pests, weeds, vegetation loss, waterside erosion, poor water quality, coastal degradation and urban land degradation. If you appreciate how lucky we are in the Helensburgh district to enjoy a relatively unspoiled bush environment you should also be aware that it is under serious threat. read more

Be Weed Wise - Madeira Vine


Madeira vine (Anredera cordifolia)


Madeira vine (also called lamb’s tail) is an invasive vine from South America. Originally it was introduced to Australia as an ornamental plant in gardens. It is no longer planted but people in older gardens could still have it growing over sheds or along fence-lines. It has become an environmental weed, locally and Australia-wide, blanketing and smothering both shrubs and trees. Once it is in flower it is very obvious throughout Helensburgh and surrounding areas. It is listed as a Weed of National Significance.


Madeira vine is a twining vine with wide, fleshy, heart-shaped leaves that are 2 to 15 cm long, with fragrant, cream-coloured flower spikes up to 30 cm long in March/April. As stems mature they develop aerial tubers which can become very large.

Dispersal: Madeira vine spreads via the aerial tubers which drop to the ground and form new plants, and also by root tubers. These tubers can be washed down creeks and drainage lines during heavy rain. The tubers can be viable for many years. The vine may also be spread in Council green waste, or dumping of garden waste in bushland.

Removal: Large vines which are smothering trees may need herbicide treatment. Pulling at the vines means that the aerial tubers drop on the ground. Smaller plants can be hand removed. All tubers and tuberous roots need to be removed. All parts of Madeira vine should be put in your red bin. Alternatively, put it in a black plastic bag and leave in the sun for some months, depending on the season. For treatment with herbicide, the 'stem-scrape' method is best. This method is also called bark-stripping or stem-painting. Stem-scraping is used for plants and vines with aerial tubers, or where underground tubers and roots are in a difficult-to-get-to place. A sharp knife is used to scrape a very thin layer of bark from a 15–30 cm section of the stem. Herbicide is then immediately applied to the exposed area soft underlying green tissue. For hard-to-reach tubers and roots, some section of stem and leaves should be left so that stem-scraping can be used. In the case of Madeira vine, all tubers within reach should be collected, removed and composted or destroyed before starting the scraping.

This local vine has bright green leaves with large yellow flowers.

Chinese star jasmine, Trachelospermum jasminoides

This evergreen vine from China has dark, glossy foliage and small, starry, white, spicy, nutmeg-scented flowers in summer. It is slow growing initially but later becomes vigorous. Variegated leaf forms are also available.
