Galloway and West Dumfries MSP Alex Fergusson has announced he will stand down at the next Holyrood election.
Ruth Davidson, the leader of the Scottish Conservative Party, has praised his role since the creation of the Scottish Parliament in 1999.
A meeting to determine the best way of managing cockling on the Solway estuary will take place tonight (18 October).
Marine Scotland will meet with local fishermen, politicians and landowners in Dumfries to discuss the future of cockling in the area.
The cockle beds have been the source of illegal poachers in recent years and concerns have been raised about their safety, because of the treacherous flow of the estuary.
The beds have been closed since September last year to allow stocks to recover.
It's hoped that tonight's meeting will allow local people a bigger say in how cockling is policed.
