Maintaining Bristle tussock (Rytidosperma setifolium)
Bristle tussock occured naturally in Marlborough as a minor species in rocky places. However, grasslands dominated by bristle tussock have been induced by repeated burning of forests, and subsequent burning and grazing of snow tussock grasslands.
GUIDELINE:
- Lightly graze Bristle tussocks grasslands if snow tussock or native woody shrubs start to encroach. Fence grassland if grazing is necessary - to prevent stock grazing other adjacent vegetation communities (e.g. C. macra which is very palatable to stock)
- Pest control
Hares, rabbits, deer, goats or chamois may deplete Bristle tussock grasslands if grazing pressure is too high.
- Establish a buffer zone to protect grassland from the management impacts of neighbouring grasslands (e.g. seed & fertiliser drift, grazing, fire risk etc.).
- Weed control
- Induced bristle tussock grasslands in Marlborough occur in broken, erosion-prone country. Bare ground provides opportunities for weeds e.g. Hieracium spp. to become established.
for more information on weed control.
- Monitor to determine success of the management option, and status of weed and animal pest populations.
