Overview

The Common Reed is the dominant plant of the Marshside RSPB reedbeds — and reedbeds are among the most wildlife-rich habitats in Britain. The Marsh Helleborine cannot grow there, but Reed and Sedge Warblers, Water Rail, Bittern (target species), Bearded Tit (occasional) and wintering wildfowl all depend on it. The rustling, swaying reedbeds are one of the characteristic sounds and sights of Marshside. Reeds are also used in traditional thatching.

Frequently Asked Questions

Why is Common Reed used for thatching?

Water Reed (Phragmites australis) has been used for thatching for thousands of years. The stems are hollow, very strong, resistant to water penetration and have a natural silica content that increases durability. A good water reed thatch can last 60–70 years. Norfolk remains the centre of UK thatching reed production, where reedbeds are still commercially harvested.
