forest sedge of shaded stream banks and damp forest floor

Size
Height: 30–60 cm
Lifespan
5–10 years
Diet
Not applicable (sedge). Photosynthetic.
Habitat
Lowland and montane forests, forest margins and damp, shaded sites. Prefers moist, well-drained soils with partial to full shade. Often forms clumps in forest understorey.
Range
Throughout New Zealand from Northland to Stewart Island. Most common in lowland and montane forests. Widespread in forest understorey.
Endemism
Endemic
Main Threats
Habitat loss from land clearance is the primary threat. Browsing by introduced possums and deer. Climate change affecting forest habitats.
Population
Populations are considered stable and widespread. The species is common in forest understorey throughout New Zealand. It is threatened by ongoing habitat loss.
Conservation Status
Not Threatened
Walk the forest understorey on a damp day. Look for the graceful, arching clumps of dark green leaves. That is forest sedge. It is everywhere. And it is easy to overlook. Forest sedge forms graceful, arching clumps of dark green leaves. The leaves are narrow and soft, arching outward from the centre of the clump like a fountain or a green explosion frozen in time. The seed heads are brown and held on short stalks, unremarkable from a distance but interesting up close. It grows in forest understorey, often along tracks and in damp areas. It is one of the most common sedges in New Zealand's forests, found from sea level to the montane zone. A plant of the shady places, a sedge of the forest floor. It does not demand attention. It does not need to. The leaves were used by Māori for weaving small baskets and for thatching. The soft, arching leaves were easier to work with than the leaves of other sedges. A practical plant, not just a pretty one. The fibres held together. The baskets lasted. The plant provides habitat for insects and lizards. The dense clumps offer shelter from predators. The seeds are eaten by birds. A small contributor to the forest ecosystem, but a contributor nonetheless. Remove it and something would notice. To find forest sedge is to walk the forest understorey. Look for the graceful, arching clumps of dark green leaves. It is a plant of the shady places, a sedge of the forest floor. The leaves arch like a fountain, a quiet presence in the green. Not rare. Not threatened. Not famous. Just there, in the understorey, doing its sedge thing. That is enough. That is forest sedge. Common, useful, and easily ignored. The quiet worker of the forest floor, the one that holds the soil and shelters the insects, asking for nothing but a bit of shade and a bit of damp.
