The bushtucker walk - part of UNSW's groundbreaking Green Trail - is now open to the public.

The walk, which takes visitors around the Kensington campus, highlights the beauty and ecological significance of the plants native to the Sydney metropolitan area.

About 25 different indigenous foods or useful plants are signposted, with more to be planted this semester.

Green Trail guides, organised by the Ecoliving Centre, offer tours of the trail, with podcasts explaining its features able to be downloaded. Alternatively, brochures can be collected for free self-guided walks.

The bush walk is one of three themed eco-tours of the campus that will comprise the Green Trail -- part of UNSW's bid to be Australia's leading "green" university.

Phase two of the Green Trail will highlight the buildings and technologies on campus, demonstrating how a large organisation can run in the most efficient and "green" way. Phase three will introduce visitors to the centres of world class research into environmental sustainability located on the campus.

Local elder Aunty Ali Golding performed a Welcome to Country at last week's launch of the Trail by local MP, Peter Garrett. About 100 people, including the Vice-Chancellor Professor Fred Hilmer, attended the opening of the bushtucker walk.

Brochures for the self-guided tours can be collected from the Reception desk in the Chancellery building (enter from Gate 9 High Street). Guided tours for schools and other special interest groups can be arranged through Cameron Little, Ecoliving Centre, phone 9385 6940 or email
