This paper explores how time affects the value of nature's services. Researchers studied a Dutch national park, Hoge Veluwe, for a century to track changes in three services nature provides. They found that over decades, the importance of these services can shift significantly. This information is crucial for making decisions about how to manage nature. Managers need to consider these shifts and uncertainties when planning how to protect ecosystems. Since nature can take a long time to react to humans' actions, looking at long-term changes in service values is key. It's important to think about multiple services to be ready for unexpected changes in nature's benefits.
