Annexe 6 : Blue staining in maritime pine wind-thrown (Pinus Pinaster) stored on site ABSTRACT CONCERNING : Ongoing research project TYPE OF DOCUMENT : Ongoing experiment THEME : Conservation 3.1.1. : In situ storage, live conservation of wind-thrown trees ORIGINAL TITLE : Evolution du bleuissement des chablis de Pin maritime dans le massif Landais AUTHORS : J. Moreau (AFOCEL), J.R. Liarçou (CRPF Aquitaine) PUBLICATION DATE: 02/2001 ORGANISATION : AFOCEL, CRPF COUNTRY: France ABSTRACT CONTENT: After the hurricane that occurred in France in December 1999, the huge amount of wind-thrown wood involved phytosanitary hazards. In the short run, the most formidable threat of depreciation for saw-logs was the development of bluestain. Hence AFOCEL lead with CRPF a study in order to monitor the evolution of bluestain contamination in maritime pine windthrown stored on site in South West of France. Each month, from March to December 2000, the degree of bluestain development in wood was assessed on 600 fresh saw-logs selected just after felling on 20 damaged stands. The contamination of the wind-thrown trees remains limited. One year after the storm, 40% of saw logs observed were not contaminated by bluestain. Before the insects attacks occurred no bluestain damage was notice on logs on dry site but there were several logs contaminated on wet site. On such land trees contamination could have happen through broken roots. After insects attacks the contamination of the logs rapidly reach 60% on both type of site. If a storm occurred in winter season, we could make this simple recommendation: to harvest first wind thrown trees on wet sites and quickly before insects attacks. 18 Project Coordinator : CTBA, 10 avenue de Saint Mandé 75012 Paris, www.ctba.fr/stodafor/index.htm Project partners : FVA (D), KVL (DK), EMPA (CH), CBE (P), BFH (D), UPM (E), DLFRI ( DK), TTI (I), AFOCEL (F), TUD (D), BRE (UK), FMRE (A), ICSTM ( UK), UOP (UK), NISK (N)
Annexe 7 : Conservation of maritime pine windthrown in the South West of France ABSTRACT CONCERNING : Ongoing research project TYPE OF DOCUMENT : Ongoing experiment THEME : Conservation 3.2.1 : Water storage, compact pile with water sprinkling / spraying (logs with bark) Conservation 3.1.1 : In situ storage, live conservation of wind-thrown trees ORIGINAL TITLE : Qualité des fibres issues des bois de chablis de pin maritime AUTHORS : J. Moreau, P. Nougier, G. Chantre (AFOCEL) PUBLICATION DATE: mars 2002 ORGANISATION : AFOCEL COUNTRY: France ABSTRACT CONTENT: After the hurricane of December 99, 25 millions of m 3 of maritime pine windthrown wood were stored on-site in South West of France (accounting for three harvesting years). Various means were used to face this huge incoming wood amounts before wood gets degrade, like the increase of harvesting means and rate of sawmill production, exportation and storage of round logs. In South West of France, different methods were used to store the maritime pine windthrows. The different methods were (1) on site conservation of blown trees, (2) wet storage and (3) dry storage. Regarding the lack of experience of such conservation techniques on maritime pine, a sampling procedure was adapted to follow up the evolution of wood and fibre properties on the storage sites : moisture content, pulping yield and Kraft paper properties were assessed every month. Several years after the hurricane, significant experience and expertise is acquired. Blown trees stored on site were well preserved until the end of the first summer. Fibre and paper properties were firstly affected, then pulping yield, but much lower than harvested logs. The degradation between stands was heterogeneous, so that practical methods of selection should be set up to define different qualities of wood assortments. Two years after the hurricane, a major part of trees left on site could still be used for pulp and paper issues. The storage under water sprinkling, if it is well carried out, preserves the wood quality. After a 18 to 24 month period of wet storage, the quality of pulping logs of maritime pine is maintained. But the quality of debarked logs of maritime pine windthrows stored in compact piles can be worrying. The drying rate of these logs was not fast enough to ensure an optimal protection against the fungus attacks. Analysis of wood and fibre characteristics helps to understand the progressive and heterogeneous alteration of the wood papermaking potential, and contributes to enhance the experience for the maritime pine log storage techniques. 19 Project Coordinator : CTBA, 10 avenue de Saint Mandé 75012 Paris, www.ctba.fr/stodafor/index.htm Project partners : FVA (D), KVL (DK), EMPA (CH), CBE (P), BFH (D), UPM (E), DLFRI ( DK), TTI (I), AFOCEL (F), TUD (D), BRE (UK), FMRE (A), ICSTM ( UK), UOP (UK), NISK (N)
