Summary

This study investigates whether environmental education can increase public acceptance of sustainable roadside vegetation management strategies. The research was motivated by the tension between the economic and ecological benefits of sustainable practices—such as reduced mowing costs, improved water quality, and increased biodiversity—and public resistance to the less manicured aesthetic of native plantings. Despite Delaware’s efforts to replace turf grass with native meadows and shrubs, negative public feedback often forces transportation departments to revert to traditional, expensive mowing regimes. The primary objective was to determine if informing the public about the benefits of these strategies would alter their perception and increase support. The researchers conducted an Internet survey involving three groups of participants: a control group, a group that read a list of facts about roadside management, and a group that viewed a six-and-a-half-minute educational video. All participants rated eleven images depicting different roadside vegetation strategies, ranging from the baseline mown turf to various native meadows and shrub masses, on a scale of desirability. The study utilized Chi-square tests to compare response distributions between the treatment groups and the control, as well as to compare all strategies against the baseline mown turf. The results indicated that environmental education significantly influenced public perception. Participants who read the informational list showed a significant change in perception for three of the images compared to the control group, while those who viewed the video showed significant changes for four images. When comparing all strategies to the baseline mown turf, every alternative strategy had a significantly different response distribution. Specifically, respondents rated flowering meadows, meadows with mown turf margins, and native shrubs and trees as more desirable than mown turf. Conversely, grassy meadows without flowers were rated less desirable. Grouping strategies by attributes revealed that images featuring flowers or a mown turf margin were preferred over pure turf or grass meadows. The findings suggest that public acceptance of sustainable roadside management is not fixed but can be improved through targeted education. By increasing awareness of the economic, environmental, and aesthetic benefits, transportation departments can mitigate public resistance to less manicured landscapes. This implies that integrating interpretive strategies, such as videos or informational lists, into public outreach can facilitate the broader implementation of sustainable vegetation practices, allowing for cost savings and ecological restoration without sacrificing public support.

Key finding

Providing written information about sustainable roadside benefits significantly altered public perception for three vegetation strategies, while video education altered perception for four strategies, with respondents generally preferring flowering meadows and shrubs over traditional mown turf.
