Shelter Row Spacing

SINGLE ROW SHELTER LINE

2 metre spacing for larger trees e.g.Eucalyptus, Macrocarpa, Pine, Poplar
1.5 metre spacing for medium to large trees e.g.Acacia, Alder, Casuarina, Leyland Cypress, Thuja, Willow
1 metre spacing for small to medium trees/shrubs e.g.Coprosma, Corokia, Dodonaea, Escallonia, Flax, Griselinia, Hoheria, Olearia, Phebalium, Photinia, Pittosporum

DOUBLE ROW SHELTER LINE

2 metre spacing for small to medium bushy trees/shrubs to prevent ground level winds. Plant opposite gap in adjacent row.
Coprosma, Corokia, Dodonaea, Escallonia, Flax, Griselinia, Hoheria, Olearia, Phebalium, Photinia, Pittosporum
2 metre spacing for medium to larger trees giving 50% reduction in wind velocity. Alder, Banksia, Casuarina, Eucalyptus, Leyland Cypress, Poplar, Willow. Also, larger trees to be used for timber (where trunks will be pruned). Eucalyptus, Lusitanica, Macrocarpa, Pine but here, spacing should be a minimum of 2 metres between fence and adjacent row.
