- Primary choice for woodlot planting in the Bay of Plenty
- adaptable to a wide range of sites
- supported by a well developed infrastructure
- requires a minimum rotation of 28 years to maximise wood quality and price on the local market
- requires a high number of plantings/ha to maximise the return with a 20-25 years for export
- plant at 800-900 sph (stems per hectare)
- high value timber ranging from white to red in colour
- viable choice for small woodlots
- require a 40 year rotation
- require specific site conditions for the different species
- different varieties have different sawing/seasonal abilities and frost tolerances
- plant at 1500-1600 sph no further apart than 3 m
- thin to 1000 sph when trees 5 m high
- thin to 500 sph when trees 12-15 m high
- finally thin to 70-100 sph when trees 25 m high
- very little pruning is required
- the main Acacia species for alternative woodlot use is Tasmanian blackwood
- Silver wattle (A. dealbata) has similar wood properties as Tasmanian blackwood but is lighter in colour
- Silver wattle grows faster and tolerates drier conditions but requires sheltered sites to maintain good form
- the performance of Silver wattle as a woodlot species is still being assessed
The two main Cupressus species used for woodlots are the Monterey and the Mexican cypress
cypress wood is similar to kauri and is used for furniture, turnery, panelling, untreated weatherboards or shingles, and boat building
the Monterey cypress has darker more grainy wood but is more susceptible to canker disease
- cypress grow well on cool southerly facing slopes
- Mexican cypress also performs well on warmer northern slopes
- the Monterey cypress is tolerant of exposed sites
- both species can be used for shelterbelts
- establish trees at 1100 sph (3x3 m)
- form prune at the end of the second season to remove forking leaders
- when trees are 3-4 m high thin to 800 sph removing poorly formed or unhealthy trees
- side lift prune up to where the trunk is 12 cm thick when trees are 3-4 m high and repeat every two years also pruning the six largest branches above the 12 cm diameter limit until the pruning height of 6 m is reached
- when trees are pruned to 6 m high thin to 600 sph
- timber is used in New Zealand as a light framing timber and internal roof beams
- natural resistance to borer
- cannot be treated with copper-chrome-arsenic wood preservatives but an oil preservative eg creosote must be used for exposed timber
- 40-50 year rotation
- prefers cool, moist inland sites
- plant at 1370 sph (2.75 x 2.75)
- thin to between 300-500 sph 12-17 years after planting when trees are 10-15 m high
- high value and sought after timber
- 50 year rotation
- requires sheltered sites with deep fertile soils
- established at 600-1250 sph initially depending on plant stock, soil and site quality
- as the black walnut is deciduous low stocking numbers are not recommended on sites at risk from weed invasion
- thin, when crown competition begins to occur, down to 60-70 sph
- prune side branches before they exceed 50 mm in diameter up to 6 m but do not remove anymore than 25 % of the green crown in any one operation
