Magnificent Mires

The Magnificent Mires partnership project celebrated the fascinating, unrivalled natural and cultural heritage of one of Devon’s least known landscapes – the internationally important blanket bogs of Dartmoor.

Most visitors to Dartmoor are attracted by the tors and torrent streams, but what lies at the heart of the moors is a little known world of remarkable plants and rare wildlife.

Carnivorous sundews and butterworts lurk amongst the blanket bogs, trapping unsuspecting insects; wading birds come here to breed including the world's most southerly population of breeding dunlin; and sponge-like sphagnum mosses in shades of green, gold and red create a bouncing blanket across the land.

Blanket bogs also help us

Blanket bogs are located at the headwaters of many of Devon’s larger rivers including the Dart, Tavy, Taw, and Teign. The sphagnum moss which makes up the bog has amazing absorption properties. In times of heavy rainfall, the moss soaks up water and then delivers clean, naturally filtered supplies in times of drought. Peatlands are also a vital carbon store; Dartmoor alone stores an estimated 10 million tonnes of carbon in its peatland soils which is equivalent to an entire year of carbon dioxide emissions from UK industry.

A habitat under threat

In the past, activities such as peat cutting, over-grazing and burning, military usage and recreation have caused damage and erosion. As the habitat degrades, the ability of the bogs to deliver the services vital for local communities declines. Reduced biodiversity, poor water quality, carbon release and the loss of important historic records which span millennia are all a result of bogs drying out and eroding.

The good news is that today’s farming and landowning custodians are working hard to manage the blanket bogs for people and for wildlife.

The Magnificent Mires project was led by Devon Wildlife Trust in partnership with Dartmoor National Park Authority, Dartmoor Preservation Association and The Duchy of Cornwall. The project was supported from October 2016 - October 2017 by the National Lottery through the Heritage Lottery Fund.
