Goal: Actively encourage an increase in native woody plant cover



Altitude: Low to Mid. (i.e. below the natural )

The rate and direction of vegetation succession will depend on the climate, viability and composition of seed in the soil, the condition, composition and density of tussocks present, and the presence and type of weed species.

Where tussock cover is sparse, or where native woody plants are common, it may be a more realisitic goal to improve the stability of the tussock grassland by actively encouraging a shrubland/forest community. Ecologists have suggested this as an option where Hieracium is already dominant in open mixed short/tall tussock grasslands.

MANAGEMENT GUIDELINE:
  • Nil grazing. However, periodic light grazing may help to exclude competitive exotic grasses once shrubland has become established.

  • No burning

  • Establish a buffer zone to protect the area from the management impacts of neighbouring grasslands (e.g. seed drift from OSTD; fire risk).

  • Restoration of native woody species may be needed.

  • Weed control
    Weeds which can potentially overtop native vegetation (e.g. wilding pines, gorse) are the highest priority for control. However, the role of exotic woody weeds as nurse crops is a viable long term strategy.

  • Pest control
    Animal control will be essential in most areas. However, some communities e.g. kanuka shrubland found in semi-arid areas, appear to benefit from some rabbit grazing which removes the competitive grasses.

  • Monitor to determine success of this (passive) management option, and status of weed and animal pest populations. for more information on monitoring in tussock grasslands.

Management to encourage native woody plants is generally not compatible with managing an area for pastoral use. In some areas the woody plant areas should be fenced off.
