Event/seminar title Strategic Integrated Research in Timber Harvesting United Kingdom Sitka spruce

Event/seminar title Strategic Integrated Research in Timber Background  Aim to increase yield without loss in quality.  Investigated progeny selected primarily for: Stem straightness Vigour of growth Density (pin penetration) Queen Charlotte Island (QCI) control

Event/seminar title Strategic Integrated Research in Timber Materials Overview Scientific Tree Industrial Tree Discs Radial & Clears Strips Logs& Discs Radial Strips & Battens – 48 Trees144 Trees

Event/seminar title Strategic Integrated Research in Timber Measurements on standing trees

Event/seminar title Strategic Integrated Research in Timber

Event/seminar title Strategic Integrated Research in Timber Scientific Trees!

Event/seminar title Strategic Integrated Research in Timber Less Branches - Straighter Stems Density Vigour Straightness QCI

Event/seminar title Strategic Integrated Research in Timber Improved Yield

Event/seminar title Strategic Integrated Research in Timber Comparable Stiffness – Structural Sized Timber Density VigourStraightness QCI Modulus of Elasticity kN/mm2

Event/seminar title Strategic Integrated Research in Timber Clear Wood Properties MFADENSITY STIFFNESSSTRENGTH QCI VIGOUR STRAIGHT. DENSITY

Event/seminar title Strategic Integrated Research in Timber What Have We Seen…  A successful increase in volume  Future breeding for timber quality should be possible  The research didn’t end here…
