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 - Cocos palm & Canary Island date palm

Cocos palm (Syagrus romanzoffiana) and Canary Island date palm (Phoenix canariensis)


Cocos palm

Cocos palm is native to South America. It is invasive in Queensland and NSW, as well as places like Florida and Honduras. This palm is single-stemmed palm that grows to an average height of 12m. Tall fronds up to 5m long bear leaves with a green upper surface and greyish undersides. The Cocos palm is known for its bunches of orange yellow fruits (each fruit 2.5cm in diameter), and often has an untidy appearance due to hanging dead fronds and fermenting dropped fruits.

Canary Island Date Palms

Canary Island date palm is naturally found in the Canary Islands. It has also naturalised in many countries and is regarded as a weed in Australia and California. This palm has a strong trunk that is scarred with old leaf bases and long gracefully arching fronds. The lower leaflets on each frond are reduced to stiff sharp spines. Large golden-stemmed panicles of small, 3-petalled, often yellow flowers are followed by soft, single-seeded, orange to near-black fruits.

Dispersal: These palms reproduce entirely by seed. These seeds are spread by bats and other animals that eat the fruit. The seeds are also dispersed by water and in dumped garden waste.

Removal: Small palms can be dug out, larger ones will require specialised equipment, e.g. a registered tree removalist. If you wish to keep your palm, please remove inflorescences before fruit appears. Both these palms are on the Exempt Tree list for Wollongong City Council. This means that once the palm is positively identified, you can remove it without having to apply to Council for permission.
