Tasmania's Great Poo Hunt - number two - is about to begin. A clarion call has been sounded for volunteers to join the search - for fox scats. 

The island state was considered free of foxes until about 2000.

Since then, enough evidence - excluding an actual live fox - has mounted for almost $60 million of state and federal money to be spent funding Tasmania's Fox Eradication Branch for 10 years, until 2016.

The doubters, non-believers in the existence of Tasmanian foxes, scoff at the effort, casting aspersions on the origin of fox-positive scats and carcasses and the program's funding.

However, branch manager Alan Johnston has no doubt there are foxes in Tasmania.

Four fox carcasses and 40 fox-positive scats have been found in the past few years, he said.

Alison Foster, head of the branch's Scat Collection Survey, on Thursday announced the three-month "Great Poo Hunt, Phase 2" would begin on March 2.

The hunt collects and identifies carnivore scats (animal faeces) to help locate areas of fox activity across more than 300 private properties and reserves in southern Tasmania.

Phase 1, completed in the state's northeast last year, found five fox-positive scats in areas that are now the focus of intense monitoring and eradication activities.

In each phase of the survey, about 300 survey units of nine square kilometres are selected and surveyed on foot for all carnivore scats that are then DNA tested for foxiness in Canberra.

"The Scat Collection Survey is also looking for the community to get further involved by seeking volunteers to help with the fieldwork," Ms Foster said.

"We had important support from volunteers in the northeast for phase 1 and we hope people will also help out in the south of the state.

"There are some great opportunities for volunteers to get involved."

Phase 3 will be completed in the northwest next year.
