PNG timbers include a huge spectrum of colour, grain density and strength combinations. Only some timbers are suitable for processes such as peeling, slicing or drying, and some woods are not amenable to gluing or preservative treatment using available technologies. Although much data has already been published on the properties and processing methods for timbers harvested from PNG's primary forests, there is limited information available for the utilization of lesser-known timbers of a younger age. The following technical reports are the result of an intensive testing program undertaken at the PNG Forest Research Institute (FRI) in Lae to assess the processing characteristics of selected PNG timber species harvested from plantations and secondary (regrowth) forests:
-
Technical report on the physical and mechanical properties of 26 PNG timbers
-
Technical report on the machining characteristics of 25 PNG timber species
-
Technical report on the gluing characteristics of 24 PNG timbers
- Technical report on the treatability properties of 28 PNG timbers

PNG's vast reserves of natural forests and plantations contain a wide range of tropical hardwoods and softwoods, which are suitable for engineered wood products (EWPs). Within this spectrum, it is possible to find every colour, grain, density and strength combination possible in the timber world. For this reason, it is important that processors and manufacturers make considered decisions when selecting which species will be used for which products to avoid wasted resources (time, money, materials) and to ensure that their products are fit-for-purpose for the duration of their intended design life. The following timber selection resources are available:
- MS Excel spreadsheet containing PNG commercial timbers suitable for EWPs
- MS Access database containing PNG commercial timbers suitable for EWPs
- Online databases which provide a guide to using the right timber in PNG
- Technical report on potential uses for 26 PNG timbers from plantations and secondary forests.
