THE call is out for Tasmanians to sign up for "poo patrol".

Volunteers are needed to the Great Poo Hunt to help map Tasmania's wildlife and invasive species.

About 20 people have already signed up to take part in a $1 million project collecting animal droppings, to find out where they live and what they eat.

The project is a collaboration between the Department of Primary Industries, Parks, Water and Environment and the University of Canberra.

It will use the latest DNA sequencing technology to analyse predator scats.

Project officer Elise Dewar said 40 volunteers were needed for the Great Poo Hunt.

"While it doesn't sound glamorous, it provides an opportunity to visit interesting places off the beaten track," she said.

Volunteers will need to commit to at least five days work and be willing to spent time away in the field, with food and accommodation provided.

Ms Dewar said the survey sites were in the state's east.

The first poo hunt was held between 2008 and 2010 by the Fox Eradication Branch and focused on identifying droppings for fox DNA.

Ms Dewar said it helped identify locations of fox activity in Tasmania and more than 6000 scats were collected.

"The 2014 survey is part of an expanded monitoring program that looks at all invasive predators, feral cats and dogs, as well as foxes, and native predators, devils and quolls, plus what they have been eating.

"This will help map predators and prey in Tasmania and provide really important data for informing conservation and invasive species programs," Ms Dewar said.

The project is funded by the Invasive Animals Cooperative Research Centre and will receive $1 million between 2013 and 2017.
