Visitors to Loch Leven are being asked not to partake in water sports to protect birds there.
Nature Scot is reminding people that from September 1 to March 31, people are advised 'not to use canoes, kayaks, paddle boards, rowing boats and similar craft'.
It's in order to avoid disturbing the birds that rest at the loch, following long migrations. The number can reach 40,000 birds at the peak.
Scotland's nature agency says it's important to remind people because of the jump in water sport enthusiasts. The guidance has been in place since 2006.
The loch also has a year-round restriction with no access at any time for motorised or sail craft.
Jeremy Squire, NatureScot's Nature Reserve Manager at Loch Leven, said: “We want everyone to enjoy visiting the reserve, but we're asking people to remember that Loch Leven is a National Nature Reserve, where we work to protect wildlife.
“In recent years, we’ve seen a sharp rise in the number of people going out on the water, and cumulatively that can cause significant disturbance for the birds as they are attempting to rest and feed.
“We hope that visitors will understand and help us to protect nature at this special place by following the guidance in place at this important time of year for birds. By being responsible, people can help preserve what makes Loch Leven so special.”
The organisation says there's many other activities visitors can get involved in during the autumn and winter months.
During the winter, people can witness one of Scotland's 'greatest wildlife spectacles', as thousands of geese take flight at dawn or return at dusk.
Visitors are also being urged to always follow the Scottish Outdoor Access Code when visiting the reserve.
