Firth of Tay
The Firth of Tay (Scottish Gaelic: Linne Tatha) is a firth in Scotland between the council areas of Fife, Perth and Kinross, the City of Dundee and Angus, into which Scotland's largest river in terms of flow, the River Tay empties. The firth has a maximum width of at Invergowrie.
Helford River
The area falls into a Special Area of Conservation (Fal and Helford), Site of Special Scientific Interest (Lower Fal & Helford Intertidal) and the Cornwall Area of Outstanding Natural Beauty. The growth of eco and sustainable tourism have seen the development of tourism by Helford River Expeditions focusing on the natural surroundings. The National Trust play an important role with their strategy. Natural England (formerly English Nature) contributes by protecting and monitoring the area. The river is unique in that it is not wholly managed by a specific port or river authority, but brings together major environmental groups and organisations interested in the protection and development of the river. These introduce and recommend safeguards, such as those put forward by Helford River Marine Conservation Group.
