Observations
- Fusta de creixement lent.
- A Gabarró anomenem paquets de flandes “curt” els paquets de llargs inferiors a L.3900. Els paquets de llarg 4200 en endavant els considerem “llargs”.
- Hi ha sectors o industrials que tenen alguna preferència pel que fa als llargs. Els fabricants de premarcs, per exemple, busquen llargs molt concrets, principalment L.4500 i L.5400.
