Some research objectives of the lab
n 
The search for alternative species previously considered as
secondary, to avoid total extinction of preciousw wood
species such as rosewood (Dalbergia sp.)
n 
Knowledge of wood properties to choose species adapted for
different uses, and ensure the sustainability (both biological
and strength)

Objectives of SPIRMADBOIS
project
n 
Establish a NIRS calibration model to estimate the Malagasy
wood properties: Density (x-ray), lignin, cellulose,
hemicellulose, extractives, natural durability, energetic
properties

Perspectives
n 
Project still ongoing
n 
New opportunity for a new research project about
identification of precious wood (rosewood and ebony)
funded by FED/EU:
n 
Wood anatomy (Faculty of Science)
DNA barcoding (University of Zurich)
n 
NIR, FR-IR techniques?
