「困った木」で作る 時木の積層

どの街にも存在する「街路樹」。自然環境を保ち、日差しや騒音を防いだり、街の景観を良くするなど、街路樹にはさまざまな役割があり、国土交通省の調査によると2022年には全国に約630万本もの街路樹があるといわれています。今回取得したのは、道路整備の過程で伐採された神戸の街路樹。台風などの自然災害による倒木や病気などの老朽化によって、安全な道路環境の維持が困難になった場合に伐採されるわけですが、植えたあとの保全や整備がゆきとどいていない場所が多いことも大きな課題。市街地を中心に当たり前にある街路樹と共存し続けるためには、長い目で見据えて行くことが必要そうです。

Tree that have Given Up the Place on the Road

“Street trees” exist in every city, playing various roles such as preserving the natural environment, blocking sunlight and noise, and improving the streetscape. According to a survey by the Ministry of Land, Infrastructure, Transport, and Tourism, there were approximately 6.3 million street trees across the country in 2022. What we acquired this time were street trees from Kobe, which were felled during road maintenance. These trees are typically removed when natural disasters like typhoons or disease-related aging make it difficult to maintain a safe road environment. However, a major issue is that many areas lack proper post-planting care and maintenance. In order to continue coexisting with street trees, which are an integral part of urban landscapes, it is necessary to take a long-term approach to their care and preservation.
