About the reserve

Wildlife highlights

Take a walk to our new bird hide and viewing platform for fantastic views across the mire to the hills beyond. 

This nature reserve is a fantastic place to see birds all year round, including birds of prey; invertebrates, including many species of dragonfly and butterfly, and much more.

• Spring - Birds displaying and cotton grasses flowering across the mire. Bog plants such as bog rosemary, heather and cranberry are at their best.  You might be treated to breeding displays of curlew, skylark and reed buntings. Red grouse, redshank, snipe and grasshopper warbler also breed here. Reptiles and amphibians emerging from their hibernation.  The arrival of migratory birds such as cuckoos.

• Summer - the nationally rare large heath butterfly is on the wing from June to August looking for cotton grass on which it lays its eggs. This is the time to find adders and common lizards basking. Cranberry, bog rosemary and later heather are in flower.  You can find all three species of sundew here including the scarce great sundew. Sundews have adapted to low nutrients of the bog by trapping and digesting flies on sticky filaments on their leaves. The pools near the nature reserve entrance are alive with dragonflies and damselflies during the summer months.
• Autumn - Also look out for short-eared owls hunting over the moss. Also, a good time to see the elusive hobby and other birds of prey including peregrine falcons.  Still plenty of dragonflies about too, with very impressive numbers of black darters.
• Winter - Drumburgh Moss nature reserve often hosts small numbers of geese from the huge flocks on the Solway. Other wildfowl include teal and sometimes flocks of black-headed gulls.  Hen harriers can sometimes be seen roosting.

A threatened habitat

Raised mires were formed following the last ice age when dead vegetation gradually in-filled a body of standing water forming peat, which eventually became raised up above the surrounding land.

In recent years much of this habitat has been lost or damaged, making it one of western Europe’s most threatened habitats.

How the moss is formed

Being raised, the bog surface gets all its moisture from rain water which is lacking in nutrients. The bog vegetation is largely made up of Sphagnum moss, of which 13 species have been recorded on the nature reserve. Sphagnum moss, is highly absorbent, and can hold large amounts of water acting like a giant sponge.  

Sphagnum moss is not the only bog plant to be found. Drumburgh Moss nature reserve is home to a number of specialist bog plants. In spring, the moss is a profusion of the white heads of cotton grass, dancing in the wind. 

Working to restore the moss

Past drainage and peat cutting of the moss and surrounding farmland has meant that Drumburgh Moss is much drier than it should be.

The Trust has carried out extensive restoration works: blocking ditches, reprofiling peat faces and removal of trees and scrub all help to raise the water level so that the bog vegetation can start to regrow.

Keeping it special

Around the moss are areas of wet and dry heath, scrub and grassland which are managed by grazing. We use native breed cattle and hardy Exmoor ponies to keep the vegetation open.

Drumburgh Moss is designated as a Site of Special Scientific Interest and is part of the South Solway Mosses Special Area of Conservation.

The main nature reserve was purchased by Cumbria Wildlife Trust in 1981, however various extensions have been purchased since then.
