The STTC provides a dedicated platform where research and publications on LUS from sources worldwide are pooled.
Globally, the tropical timber sector focuses on a relatively few species. This can put supply stress on these varieties, limit availability and reduce the commercial appeal of implementing SFM.
The STTC encourages use of a wider range of verified sustainable lesser used species (LUS), also referred to as Lesser Known Timber Species (LKTS), through marketing and technical evaluation support. The goal is to reduce over reliance on key varieties, and, by increasing sustainable timber off-take from a given forest area, make sustainable management a more viable business proposition.
The STTC supports various projects in field of LUS. Among them is www.lesserknowntimberspecies.com, managed by FSC Denmark, which is focused on providing both inspiration and knowledge. The database shows the potential of this underutilised timber source, helping buyers and specifiers make new choices which support SFM. The database is currently in English, French, Spanish and Dutch.
The Best Practice Guide “Promoting The Lesser Known”, supported by the STTC Lesser Known Species Consortium (2012-2016), describes the steps to be taken to introduce LUS on a market. These include assessing of the available volume and stem quality of the LKTS considered, gaining technical information, building partnerships and marketing of the LUS.
Another valuable tool is ITTO’s www.tropicaltimber.info. This:
- Informs users on the properties, uses and availability of lesser-used tropical timber species
- Supports small and medium-sized timber producers with value-added production & marketing
- Promotes responsible forestry and certified forests
- Educate retail buyers about timber products and certified forestry
Currently in Portuguese, English, French and Spanish.
For the Dutch market, the www.houtdatabase.nl provides information on over 200 timber species, their physical and mechanical properties and uses (illustrated with reference projects), It also details suppliers and availability of timber with an SFM certificate compliant with Dutch procurement criteria.
Below is an overview of publications on LUS and their applications.
