Where found:

  • Scattered throughout Taranaki, away from coastal winds, especially in the eastern hill country.
  • Damp depressions on relatively sheltered free draining slopes. Grows well in gullies but has been known to topple.
  • Mainly suited to the lower half to two thirds of the slope depending on soil depth.
Description:
  • Medium to tall upright deciduous tree, usually with one main leader and conical crown with medium spread.
  • Smooth leaf with finely serrated (teeth) margins. Flushes pinkish-green in late September to early October. Leaves become green above and pale grey-green below.
  • Male flowers usually appear when the tree is at least 5 years old. Densely arranged in hanging catkins that usually appear before the leaves.
  • Bark of young tree is finely fissured and light brown. Hardens and becomes rougher with age.
  • Moderately affected by wind. Moderate to high leaf spot and rust resistance.
  • Low possum palatability.
  • Used for soil conservation (slope stabilisation, especially wet areas), shade, shelter, stock fodder and timber.
