Goats are being employed by the National Capital Authority to help rid the shores of Lake Burley Griffin of noxious weeds.

A herd of about 30 tame South African Boer goats will clear an area at Acacia Inlet, on the northern side of the lake, of blackberry.

The trial could see the goats being used elsewhere in the capital, for both weed management and to help chomp down on bushfire hazards.

Herds for Hire, of Bega, is supplying the animals. Owner Elisabeth Larsen said in her six years in business, it was their first job in Canberra.
