Photographer's Note

Macrocarpa
Cupressus Macrocarpa
Family : Cupressaceae
Country of Origin : United States of America
Wood Type : Softwood

Macrocarpa's natural habitat is limited to the peninsular of Point Lobos, near Monterey, in Southern California, also the home of Radiata Pine. It was introduced to New Zealand in the 1860's and was planted mainly as shelter belts but occasionally as plantations.

The timber is a low to medium density softwood (485 kg/m at 12% moisture content) and has a large amount of heartwood which is a golden brown honey colour. Macrocarpa is a moderately stiff, strong timber similar to NZ grown Douglas Fir, it is a difficult timber to kiln dry with cell collapse and internal checking the main problems.

Macrocarpa clears are very similar to Kauri in character, and machines and turns well owing to its fine texture.

Macrocarpa is one of the most naturally durable exotic softwoods grown in New Zealand, and is resistant to insect and borer attack in its sawn form.

Its heartwood is rated moderately durable which means a 50x50 stake will last 10-15 years in the ground. Larger sections will last considerably longer. Outside and above the ground macrocarpa is equivalent to H3 pine in durability. Inside where the timber is not subject to the elements, it will last virtually indefinitely.
