In this paper, we investigate whether people’s knowledge of the past influences their preferences and values towards future landscape change. “Knowledge of the past” is one aspect of the information set held by individuals, and a well-established finding in stated preference work is that changes in information can change preferences and values. The case studies used here relate to prospective changes in woodland cover in a UK national park the Lock Lomond and Trossachs. We find that people who are made aware that the landscape has changed over time are more likely to favour changes to the current landscape. Knowledge of the past therefore seems to have an impact on preferences for future landscapes.
