Forest Enterprise Scotland are looking for Perthshire sheep to help maintain a Scheduled Ancient Monument.
Their mission, should they choose to accept it, will be to graze a seasonal let in Allean Forest just north of Loch Tummel.
The sheep will help keep the four-post Na Clachan Aoraidh stone circle clear of vegetation.
Graeme Findlay for the FES team in Tay District, said the organisation are offering a 17.41 ha seasonal grazing – suitable for around 30-35 sheep - for a period of two months during September and October.
"We might consider a further period of 1 month in the spring," Mr Findlay said.
"It’s a limestone area and we are looking to get the sheep to keep the mix of grasslands on the site in the right balance, reducing the more acidic grassland plants to give more space for calcareous grassland species.
"As well as keeping the stone circle clear of vegetation, the grazing should help us to expand the rare and specialised plant communities that grow where limestone outcrops can be found by reducing the competition from other vegetation."
The site is stock-fenced and has water on-site but might need additional water in very dry weather periods.
Effective grazing in September and October is key to this, and an extension of grazing for 4 weeks in the Spring may be offered at some point in the future through agreement by both parties.
