Walking at Cock Marsh

Situated on the banks of the River Thames, opposite the town of Bourne End, the chalk grasslands of Cock Marsh make for a pleasant riverside stroll.

Wander through wildflowers

 
Footpaths weave through the grasses and wildflowers or if you’re feeling more energetic, you can climb to the top of the chalk slope to be rewarded with views over the Buckinghamshire countryside and the river below. Cock Marsh is common land and has been grazed by cattle for centuries. In the summer months, you’ll find cows in the meadow or maybe wallowing in the Thames. Grazing means that the land has become rich in wild flowers including several species of orchid. You might also find rock roses, thyme and a small, rare plant called brown galingale.
 

Protected plants

 
Brown galingale grows on the edges of freshwater ponds and flourishes when grazing animals disturb the ground, making it hard for larger plants to establish. We are one of only 12 sites in the UK where brown galingale has been found and it is so rare that it is on the ‘Red List’, a list of endangered animals and plants that risk becoming extinct in this country.
 

Looking after Cock Marsh

 
Cock Marsh has been designated as a national Site of Special Scientific Interest (SSSI) because it supports plants that find it difficult to survive elsewhere in the countryside. In order to maintain the grassland we clear areas of scrub in the winter and then it is over to the cattle to graze in the summer. This combination keeps the grass short, prevents invasive plants from establishing and encourages the germination of wild flowers.
