Two Muntjac deer have been reported in Dumfries and Galloway.
The deer are not native to the area and are thought to cause severe damage to vegetation. Scottish Natural Heritage Wildlife Operations Unit are investigating the incident.
The deer originate in China and, if they establish themselves in Scotland the SNH estimate it would cost up to £2m due to damaged crops and vegetation.
Stan Whitaker, from SNH, said: "Muntjac deer are among the most destructive animal pests in Britain."
