Some Tasmanian farmers hit hard by the devastating January bushfires are facing a slow recovery.

The Bushfire Recovery Taskforce estimates farmers in the south-east lost an average of $200,000 worth of equipment and livestock in the bushfires.

Jan Davis from the Farmers and Graziers Association says the intensity of the fires has prevented natural pasture re-growth.

"Because the heat was such that the soil was so hot the seed residues have been destroyed, so that was something [we] hadn't expected either,' she said.

Merilyn Anne Williams' three farms were affected by the fires.

She says the recovery process is daunting.

"There's a lot to be done but without all that assistance over the last few weeks it would have been a really diabolical situation," she said.

The taskforce estimates the fires cost oyster growers $3 million.
