New Caledonian Sheoak
Scientific name: Casuarina collina
Overview
New Caledonian Sheoak is a medium-sized hardwood native to the islands of New Caledonia in the southwestern Pacific Ocean. The species is adapted to the region’s unique soils and climates and is one of several distinctive hardwoods that contribute to New Caledonia’s remarkable plant diversity. Although seldom encountered in international timber markets, the wood is dense, durable, and valued locally for small construction projects, fuel, and specialty woodworking applications.
Quick Facts
- Common Name: New Caledonian Sheoak
- Scientific Name: Casuarina collina
- Region: Oceania & Pacific Hardwoods (New Caledonia)
- Tree Size: 30–60 ft tall, 1–2 ft trunk diameter
- Average Dried Weight: 56 lbs/ft³ (900 kg/m³)
- Janka Hardness: Approximately 2,000 lbf
- Color: Reddish brown to dark brown
- Grain: Straight to slightly interlocked
- Texture: Fine and even
Identification Characteristics
New Caledonian Sheoak produces a reddish-brown to dark brown heartwood that often deepens with age. The wood possesses a fine texture and subtle natural luster typical of many sheoak species. Its dense structure and attractive appearance make it suitable for a variety of specialty applications.
Key identification traits include:
- Reddish brown to dark brown coloration
- Fine and even texture
- Straight to slightly interlocked grain
- Dense and hard structure
- Typically available only in small dimensions
Working Properties
New Caledonian Sheoak can be moderately difficult to machine because of its density, but it produces excellent results when worked with sharp tools.
- Moderately difficult to machine
- Turns and polishes very well
- Produces smooth finished surfaces
- Accepts oils and finishes readily
- Excellent wear resistance
Safety Note
Wood dust may cause irritation in sensitive individuals. Appropriate dust collection and respiratory protection are recommended during machining
Common Uses
New Caledonian Sheoak is commonly used in a variety of applications, including:
- Woodturning
- Small furniture components
- Decorative objects
- Tool handles
- Carvings
- Posts and poles
- Specialty woodworking projects
- Firewood and charcoal
Sustainability & Notes
New Caledonian Sheoak is not widely harvested commercially and remains an important component of New Caledonia’s native ecosystems. Because of its limited distribution and relatively small-scale use, lumber from this species is uncommon outside its native region.

Collector Notes
New Caledonian Sheoak is an especially interesting collector species because it represents the unique flora of New Caledonia, one of the world’s botanical hotspots. Its limited availability, dense reddish-brown wood, and geographic isolation make it a desirable addition to collections focused on Pacific timbers, island hardwoods, and the diverse members of the sheoak family.
