كيف تساعد الكائنات الدقيقة أشجار البلوط على البقاء في ظل الإجهاد البيئي؟

كيف تساعد الكائنات الدقيقة أشجار البلوط على البقاء في ظل الإجهاد البيئي؟

“ Around 2,000 oaks will be used for the framework of the spire, half to be felled this year and the rest in 2022. Last month, eight Quercus petraea at the Forêt de Bercé in Sarthe, northwest France, were felled. (The IOS visited the forest during the Pre-Conference Tour in 20121.) It has been managed and harvested for centuries, since Louis XIV’s minister Jean-Baptiste Colbert chose it in 1669 to be a source for wood to build warships. Oaks were planted among beeches, at a ratio of three beeches to one oak, so that the oaks, playing catch up with the faster growing beeches, would grow straight and produce trunks of the appropriate shape for ship building. After a time, ships were no longer built of wood, yet the trees continued to grow. When architects started searching for oaks of the shape they needed for the reconstruction project, the tall, slightly tapered boles of the oaks at Bercé checked all their boxes. With the help of drone footage, eight trees were selected and later felled in front of an invited audience of journalists”
