The Parks Victoria and traditional owners' proposal plans to restore native ecological systems and control pest species such as rabbits, feral cats and foxes.

But petition proponents and Merino stud breeders, John and Rhonda Crawford, Victoria Valley, fear the plan to reintroduce dingoes to the Grampians could "decimate" the sheep industry.

"We have the biggest concentration of sheep anywhere in Australia in the Hamilton region and when we've told people about the proposal, people think it's a joke," Mr Crawford said.

The online and hard copy petitions have grained 300 and 150 signatures, respectively, since December.

"We feel there has been a lack of consultation," he said.

"The proposal was released in November and we have until January 24 to provide feedback which is ridiculous given the short time frame."

According to Parks Victoria, the plan would also help manage "overabundant" populations of kangaroos and wallabies and would form part of a string of native animals, including the Eastern Quoll and Spot-tailed Quoll, to be reintroduced to the bush.

The proposal is listed in the Greater Gariwerd Draft Landscape Management Plan which is a collaboration between Parks Victoria and the three traditional owners groups: Gunditj Mirring Traditional Owners Aboriginal Corporation, Eastern Maar Aboriginal Corporation, and Barengi Gadjin Land Council Aboriginal Corporation.

"All predators prey on the easiest thing they can catch and that's not going to be kangaroos or wallabies - it will be a sheep in the paddock," Rod Miller, who runs a Merino stud and fat lamb operation, said in November last year.

Parks Victoria regional director Jason Borg said research partnerships with farmers would be formed before investigating or trialing a reintroduction and urged people to provide feedback before January 24.
