Explore Braunton - The Most Biodiverse Parish in England

Botanical Bounty


The Burrows are internationally famous for their plant and animal life, which has been fascinating scientists and naturalists since the 17th century.

Wildflowers

Flower rich turf near Flagpole DuneNearly 500 species of wildflower have been recorded here, helping to make Braunton the most biodiverse parish in England. So much can be found, from common species such as yellow iris to rare species such as sea stock, sand toadflax and water germander – the latter being so rare that it is only found at one other site in England. The carpets of flowers encourage butterflies and 33 species of these beautiful creatures have been found here.

Marram Grass

It traps windblown sand to create what is known as an ‘embryo dune’, which grows and stabilises with the long marram grass roots to become the rolling the dunes that are so familiar here.

In 1907, C Harper wrote: 

“The winds have blown the immense accumulation of shifting sand into fantastic hummocks and weird hollows... and in some sheltered hollows where the wind comes with less scouring insistence, there are nurseries of pretty wild flowers, which, although the unskilled explorer knows it not, are botanical treasures”.

Rich Flora

Habitat Types

It must be mentioned that gathering wild flowers is strictly prohibited under the Wildlife and Countryside Act 1981. If you wish to record the beautiful specimens you find, please take a photograph or make a sketch.
