The Great Fen-sedge abounded extraordinarily, and it was one of the most extensive zones in Occidental Europe.

The larvae feed on Common Meadow-rue, Lesser Meadow-rue and Great Fen-sedge.

The fresh water of the Guadiana favors the growth of the Common Reed (Phragmites australis, Phragmites communis), and the briny water of the Gigüela favors the growth of the marshy vegetation, principally the Great Fen-sedge (Cladium mariscus).

Many insect larvae have been recorded feeding on the red-fruit saw-sedge.

Gahnia aspera known as the Rough Saw-sedge is a tussock forming perennial plant, often seen in moist situations.

Where it occurs, saw-sedge provides good breeding habitat, its tall (1.5 m, 5 ft) dense structure providing good cover for the nesting rails.

Gahnia sieberiana, commonly known as the red-fruit saw-sedge, is a tussock-forming perennial plant in the family Cyperaceae, endemic to Australia.

Cladium mariscus is a species of flowering plant in the sedge family known by the common name Saw-sedge or Sawtooth Sedge.

Gahnia radula, commonly known as the Thatch Saw-sedge is a tufted perennial sedge native to south-eastern Australia.

Gahnia (sawsedge, saw-sedge) is a genus of sedges found in Australia, New Zealand and a number of Pacific Islands.

The wetlands support a narrow zone of woodland composed of Saltwater Paperbark, with an understorey of sedges such as Coastal Saw-sedge and Schoenus brevifolius.

Desmoulin's whorl snail lives in calcareous wetlands, where there are tall sedges, saw-sedge (Cladium mariscus), reed-grass (Glyceria maxima) or the reed Phragmites australis.

Some distance off we saw men cutting reeds and grass for thatch, then they were blotted from view by a thick stand of saw-sedge, seven to ten feet tall, but giving the appearance of a simple meadow if looked upon from distance.

This grassland is particularly notable at Redgrave and Lopham for its areas of saw sedge Cladium mariscus.

In the wettest wetlands of all grows an even tougher thatching material, one of our most ancient natural crops: the giant saw sedge Cladium mariscus.

It is notable for being an internationally important site for the rare black bog rush Schoenus nigricans and saw sedge Cladium mariscus plant species.

Desmoulin's whorl snail lives in calcareous wetlands, where there are tall sedges, saw-sedge (Cladium mariscus), reed-grass (Glyceria maxima) or the reed Phragmites australis.

Thatching is the craft of building a roof with dry vegetation such as straw, water reed, sedge (Cladium mariscus), rushes, or heather, layering the vegetation so as to shed water away from the inner roof.

The fresh water of the Guadiana favors the growth of the Common Reed (Phragmites australis, Phragmites communis), and the briny water of the Gigüela favors the growth of the marshy vegetation, principally the Great Fen-sedge (Cladium mariscus).
