SITKA SPRUCE IS ONE OF THE MOST IMPORTANT SPECIES PLANTED IN GREAT BRITAIN AND IN IRELAND. IT HAS ALSO BEEN INTRODUCED IN FRANCE ESPECIALLY IN THE NORTH AND NORTHWEST, IN THE WEST OF THE MASSIF CENTRAL BUT ALSO IN THE SOUTHWEST (CEVENNES AND MONTAGNE NOIRE). THE ACTUAL SURFACE OCCUPIED BY SITKA SPRUCE IN FRANCE CAN BE ESTIMATED AT 20 000 HA.
PUBLIC AND PRIVATE FOREST RESEARCH AND MANAGEMENT ORGANISATIONS HAVE ALREADY ESTABLISHED SIMPLE PLOTS TO ASSESS YIELD AND DEMONSTRATE THINNING IN DIFFERENT REGIONS BUT NO REAL GROWTH AND YIELD STUDIES WERE PUBLISHED UNTIL NOW.

THE FIRST PART OF THIS RESEARCH WILL COLLECT ALL THE AVAILABLE YIELD DATA FROM THESE PLOTS AND EVALUATE THE PRODUCTIVITY OF SITKA SPRUCE COMPARED TO BRITISH AND GERMAN YIELD TABLES. FURTHER SAMPLE PLOTS WILL BE ESTABLISHED IN SUITABLE STANDS AND REGIONS, ESPECIALLY IN THE MEDITERRANEAN REGION.

THE SECOND PART OF THIS RESEARCH PROPOSAL WILL DERIVE NEW MODELS OF SILVICULTURAL TREATMENTS TAKING INTO ACCOUNT DIFFERENT PRODUCTION GOALS (SAW TIMBER OF HIGH QUALITY, FIBER WOOD AND BIOMASS PRODUCTION). SPECIAL ATTENTION WILL BE PAID TO THE SELECTION, THE TREATMENT MODELS WILL TAKE INTO ACCOUNT THE EXPERIENCE ALREADY ACQUIRED IN GREAT BRITAIN AND IRELAND.
EXPERIMENT HAS BEEN REMESURED IN 1974 AND TOP HEIGHT HAS ATTAINED 10 M IN 1982.
FIVE TO SEVEN TREATMENTS WITH FOUR OR FIVE REPLICATIONS CAN BE COMPARED. THIS THINNING TRIAL WILL ALSO PERMIT THE COLLECTION OF MUCH COMPLEMENTARY DATA (TAPER, GEOMETRY OF THE TREE CROWNS, BIOMASS, STAND STRUCTURE AND EVOLUTION OF THE SOCIAL RANK OF THE TREE, ETC. AND CAN CONSTITUTE A SUITABLE BASE FOR A COORDINATED INTERNATIONAL THINNING EXPERIMENT.
THE RESEARCH PROGRAMME WILL CONTRIBUTE TO A BETTER UNDERSTANDING OF GROWTH AND YIELD AND STAND DYNAMICS OF SITKA SPRUCE IN EUROPE AND THE POSSIBILITIES OF EXTENSION OF ITS ACTUAL AREA IN EUROPE.
