Alderfen Broad

Tucked away in the heart of the Broads, Alderfen contains some of the area’s finest remaining tussock fen and carr woodland.

It also supports a number of scarce plants and good numbers of invertebrates including butterflies and dragonflies. The explosive song of the Cetti’s warbler can be heard throughout the year, with reed and sedge warblers common in the summer alongside occasional grasshopper warblers.

Ditch improvement works at Alderfen

Works will be taking place along the perimeter ditch at Alderfen over the next month by the Broads Inland Drainage Board (IDB). These works are to improve water flow via a newly enmained section and through maintenance of the existing ditch. The works will involve some tree and scrub clearance and ditch restoration and will provide more suitable habitat for a variety of wildlife including water vole. If you have any further queries regarding these works please contact the Water Management Alliance on: 01553 819600 or email

Look out for Greater Tussock Sedge
One of the UK’s largest sedges, its impressive bushy tussocks can reach over a metre in height.

A circular footpath (which can often be muddy) leads around part of the site, with a viewing area over the water. Vehicular access is along a rough track (4WD recommended) from Threehammer Common, 2.5km (1.5 miles) northeast of Horning.

What to look for

Spring / summer

Swallowtail and white admiral butterflies, hairy dragonflies and red-eyed damselflies. Cowbane, marsh fern and greater tussock sedge.

Autumn / winter

Ospreys on migration. Sphagnum moss.
