Dog owners have been urged to keep their pets under control in the Manx countryside during the lambing season.
Police say this is the time of the year when vacant fields near residential areas become temporary homes for pregnant sheep.
In a Facebook post, the Isle of Man Constbulary said: “If you don’t own the field, don’t exercise your dog on it.”
Pet owners are also reminded to be wary of nesting birds as spring approaches.
People are advised to keep dogs on short leads, stay on designated paths and outside fenced areas, and stay away from agitated birds while in the countryside.
As part of a bid to protect species such as the tern, curlew and lapwing, the restrictions in the Ayres National Nature Reserve are set to take effect from 1 to 31 July, the government said.
Domestic animals walked in the reserve, which is designated as an Area of Special Scientific Interest, must be kept on a lead not exceeding (9.8ft) 3m in length.
A government spokesman said: “Oystercatcher, ringed plover, skylark and meadow pipit all nest in the area, and disturbance can lead to eggs and chicks being abandoned when they are most vulnerable.”
Those who break the rules can face fines of up to £5,000.
