Five landowners in Wales have shown interest in hosting the reintroduction of lynx, a conservation group has said.
In 2015, the Lynx UK Trust put out a plea for anyone who would be willing to allow their land to be used.
Its chief scientific advisor, Dr Paul O'Donoghue, said five sites in mid Wales came forward and it would consider their merits in future.
But the National Sheep Association said it did not want "high-level predators released in our countryside".
The Lynx UK Trust has submitted plans to reintroduce the Eurasian lynx to Kielder Forest in Northumberland on a five-year trial period.
If approved, it would import six of the cats from Sweden. It is also consulting on two sites in Scotland.
The trust also asked landowners in Wales if they would be happy to allow lynx to roam their properties.
Dr O'Donoghue said high-density forest and a large deer population were key as they are the animal's habitat and food source.
"We had five landowners in Wales come forward who were very interested, which bodes well for the future," he said.
Fears have been raised the animals could pose a threat to sheep, but Dr O'Donoghue said in Europe, the kill rate was 0.4 sheep per lynx per year.
"I'd refute anyone who says that is a massive risk to the UK livestock," he added.
Phil Stocker, chief executive of the National Sheep Association, said: "The NSA doesn't want to see high-level predators released in our countryside, not just because they will kill sheep, but also because we firmly believe that it is sheep farming that leads to the landscape, communities and ecology that people love."
If the Lynx UK Trust wanted to bring the animals to Wales, it would need a special licence from Natural Resources Wales. So far, no applications have been submitted.
Dr O'Donoghue said: "We're keeping Wales in our minds - we don't want to do too many sites in one go, so when the time is right we'll look at them more closely."
Mr Stocker said the views of people living in the areas and businesses should be considered as they "have carved out the landscapes and related wildlife".
