Libocedrus is a genus of coniferous trees in the Cupressaceae family, which is native to New Zealand and New Caledonia. This genus is characterized by its unique tree form, with scale-like leaves and small, woody cones. The trees of the Libocedrus genus are commonly known as incense cedars, although they are not true cedars (genus Cedrus).

Description

Libocedrus trees are evergreen, with a straight trunk and a conical to irregular crown. The leaves are arranged in decussate pairs and are scale-like, covering the shoots. These trees are monoecious, with male and female cones found on the same plant. The male cones are small and numerous, while the female cones are larger, consisting of just a few scales, and mature into woody, seed-bearing structures.

Species

The genus Libocedrus includes several species, among which the most well-known are:

• Libocedrus plumosa (Kawaka) - native to New Zealand
• Libocedrus bidwillii (Pāhautea, or New Zealand Cedar) - also found in New Zealand
• Libocedrus austrocaledonica - native to New Caledonia
• Libocedrus chevalieri - another species endemic to New Caledonia

Habitat and Distribution

Libocedrus species are found in temperate rainforests, where they prefer moist, well-drained soils. They are adapted to a range of environmental conditions, from sea level to alpine environments, but are most commonly found in mountainous areas.

Uses

Historically, the wood of Libocedrus trees has been valued for its durability, resistance to decay, and aromatic properties. It has been used in construction, for making furniture, and in shipbuilding. The trees are also planted as ornamental species due to their attractive form and foliage.

Conservation

Some species of Libocedrus are considered to be at risk due to habitat loss, over-exploitation, and climate change. Conservation efforts are underway in their native regions to protect these unique trees and their habitats.
