As the sustainability of tropical hardwoods is questioned by consumers, as well as architects and designers, projects like this one aggressively address those concerns and make a positive impact on the communities surrounding the tropical forests that provide timber.

Increased use of lesser known species (LKS) helps to promote sustainable forest management in developing countries and provides a critical economic incentive for local communities to manage forests rather than convert them to farms and ranches.

IWPA has worked to identify lesser known species (LKS) from around the world that have the greatest potential for the U.S. market. Whether used in applications like decking, flooring, mouldings and millwork, or veneer, these species have been deemed by a panel of IWPA experts to have the technical qualities and availability to meet the needs of architects, designers, manufacturers, and consumers.


The links below contain technical data on the species provided by the USDA Forest Products Lab. Images of species will be added as they become available. Please visit the USDA Forest Product Lab for more information about LKS and tropical hardwood species.

Hura, Acacu, Catahua, Ochoo (Hura crepitans)

Hura, Acacu, Catahua, Ochoo (Hura crepitans)

Pale yellowish brown to pale olive gray with a high luster. Machines easily, finishes well, but it may have tension wood zones that produce fuzzy and torn surface in planing. It is also easy to glue and nail. The sapwood is not distinct from the heartwood. Usually straight-grained but may be interlocked. Texture varies, with very good to excellent gluing properties.
