英國將首先採用新技術幫助樹木

In a remarkable initiative in the UK, a historic tree is set to receive innovative support. This tree, known as a London plane tree, has a rich history, having been gifted by King Charles II to the Bishop of Ely in 1674, making it approximately 360 years old. Located in a charming walled garden surrounded by lush grass and vibrant blue flowers, the tree stands proudly behind the former bishop's palace, which is now part of King's private school in the picturesque city of Ely, Cambridgeshire. This tree is not only one of the largest but also one of the oldest of its kind in the country. To ensure its preservation, experts are employing a technique that has not been previously utilized in the UK. David Day, the chair of the school governors, announced that a team of Italian specialists will implement a method called morphophysiology. This approach aims to enhance understanding of how to care for and protect the tree for future generations. The project is generously funded by a £121,000 grant from the National Lottery Heritage, which will also facilitate public access to the tree through garden opening days throughout the year. The tree was originally planted in a walled garden at the back of the bishop's palace, conveniently located near the city's iconic cathedral. Mr. Day elaborated on the significance of morphophysiology, stating that it is particularly relevant for heritage and veteran trees. This scientific study focuses on the relationship between a tree's shape and structure and its overall function, ultimately aiming to sustain its life. This marks the first time this method is being applied in the UK, primarily led by an Italian team. The National Lottery Heritage provided funding for this pioneering work, recognizing its potential to conserve other heritage trees across the UK in the future. The tree has previously had cable bracing installed during the 1940s and 1980s, but these cables now require replacement. The upcoming survey will assist in determining the best approach for this task. Mr. Day mentioned that the £121,000 grant will cover essential conservation work for the next four years, commencing in July. In addition to the Italian experts, engineers from the University of Cambridge are also contributing to this groundbreaking project. Dr. James Talbot, an associate professor in the engineering department, explained that they are working to create a theoretical model of the tree. This model will help them understand the design of the proposed cabling arrangements. To achieve this, a laser scanner has been used to capture the geometry of the tree, which will then be transformed into a structural model. This model will aid in predicting how the wind affects the tree's movement, as well as its natural motion. Dr. Talbot expressed hope that the engineers will learn how to distribute the load of a weak branch among healthier branches using the tree model. It is noteworthy that engineers typically work with seasoned timber rather than living wood, making this project a unique challenge. Approximately 30 students from King's Ely have been engaged in learning about this project as part of their science week. The work is set to begin in July and will span four years. This initiative is believed to be the first instance of a lottery grant being utilized to preserve a single tree.
