Papuan Sheoak
Scientific name: Casuarina papuana
Overview
Papuan Sheoak is a medium to large hardwood native to Papua New Guinea and parts of the surrounding Pacific region. The species is found in both lowland and upland forests and is valued locally for its dense, durable timber and adaptability to a variety of growing conditions. Although seldom seen in international lumber markets, Papuan Sheoak produces attractive, fine-textured wood suitable for construction, specialty woodworking, and turning applications.

Collector Notes
Papuan Sheoak is an excellent collector species because it represents one of the lesser-known native hardwoods of Papua New Guinea. Its dense, fine-textured wood and limited international availability make it an appealing addition to collections focused on Pacific timbers, island hardwoods, and the diverse members of the sheoak family.
