The, The Dee is a major east coast Scottish river, which flows uninterrupted for some 130 km from its upland reaches in the high Cairngorms to the North Sea. (Unpublished PhD Thesis) [Google Scholar] Population declines have been caused by factors such as pearl-fishing, pollution, acidification, organic enrichment, siltation, river engineering, and declining salmonid stocks. Margaritifera Margaritifera or freshwater pearl mussel is an endangered species, protected under the Wildlife and Countryside Act 1981 and therefore it is an offence to disturb, take, injure or kill.

Freshwater pearl mussels, the jewel in Scotland's crown, extinct in 11 rivers. A subset of the Middle list. The freshwater pearl mussel and its habitat are fully protected by law, under Schedule 5 of the Wildlife and Countryside Act 1981 (as amended) and Annex 2 of the Habitats Directive. Both projects are supported by Natural England and the Environment Agency. The decline in pearl mussel populations is due to a number of factors: Margaritifera margaritifera was formerly widespread throughout western and northern parts of Great Britain. Iain Sime, SNH freshwater and wetlands advice manager, said: "Freshwater pearl mussels can live to well over 100 years old, but the species is critically endangered in Europe.

Animals which are protected from their access to any structure or place which they use for shelter or protection being obstructed. Species “of principal importance for the purpose of conserving biodiversity” covered under section 41 (England) of the NERC Act (2006) and therefore need to be taken into consideration by a public body when performing any of its functions with a view to conserving biodiversity. Future repairs to the weir may be required to maintain the site as part of its gauging network.
