- Endemism
- Endemic
- Main Threats
- Habitat loss from land clearance is primary threat. Browsing by introduced possums and deer. Climate change affecting forest habitats.
- Population
- Populations considered stable and widespread. Species common in forest understorey throughout New Zealand. Threatened by ongoing habitat loss.
- Conservation Status
- Not Threatened
- Human Risk

- Te Ao Māori
- In Māori tradition, hook sedge was used for weaving. Hooked seed heads noted for ability to attach to clothing and fur. Dark colour admired. Plant known as sign of healthy forest understorey. Plant of forest. Gathered by those who knew shady places. Resource from understorey. Small hook in dark forest.
Walk through the bush. Come out with hooks on sleeves. Carex secta is distinctive sedge. Dark bronze-green leaves. Hooked seed heads. Hooks attach to passing animals, dispersing seeds. Leaves are tough. Used by Māori for weaving. Dark colour makes it popular ornamental plant in gardens. Sedge that hitches a ride.
Leaves are long and narrow. Arching outward from centre of clump. Colour is rich bronze-green. Darker than most other sedges. Seed heads held on tall stalks above leaves. Each seed has long, curved hook at tip. Design that raises questions. Answers are in fur.
Hooks are clever adaptation for seed dispersal. When animal brushes against seed head, hooks catch on fur or feathers. Seed carried away. Eventually falling off in new location. This is how plant spreads through forest. Sedge that travels on backs of others.
Hook sedge is common in forest understorey throughout New Zealand. Grows in damp, shaded sites. Often along tracks and stream banks. Dark colour makes it stand out against green of forest.
To find hook sedge is to walk forest understorey. Look for dark bronze-green leaves. Hooked seed heads. Hooks catch on clothing. Reminder that forest is full of small inventions. Plant of shady places. Sedge of forest floor.
Sedge does not apologise. Does not need to. That is how it gets around. And that seems to be enough.
