正しい言い方

• 旧城改造应把保护大型树木纳入强制评估，因为成熟树木提供的生态价值，远非短期补种可替代。(Old-city redevelopment should include the protection of large trees in mandatory assessments, because the ecological value of mature trees cannot be replaced by replanting in the short term.)
• 气候变化正改变树木物候，许多温带树木的发芽和落叶时间都明显偏移，威胁依赖它们的野生动物。(Climate change is altering tree phenology. The budding and leaf-fall times of many temperate trees have shifted markedly, threatening the wildlife that depends on them.)

避ける言い方

• 树木 when referring to a single specific tree — use 树 or 一棵树 for a single tree; 树木 is a collective noun referring to trees as a category or group, and using it to describe a single specimen sounds unnatural
