Abstract

1
Ocean shores are among the most spectacular and sought-after sites for leisure activities, including ‘nature and wilderness experiences’. Some of these activities can involve the use of off-road vehicles (ORVs) driven across extensive stretches of sandy coastlines. Yet, this recreation mode can be controversial because of environmental, cultural, social, and ethical concerns. However, ORV users often question the putative impacts, especially the ecological aspects.
2
Here, we review the available published data about the ecological impacts of vehicles on coastal plants. We focus on vegetation because of its critical role in coastal resilience and its foundational role in the structure and function of dune-beach systems. The principal type of evidence is a formal meta-analysis of effect sizes that can be unambiguously linked to ORV use.
3
The evidence of serious ecological harm caused by ORVs to plants of beach-dune habitats is geographically widespread, extensive in taxonomic coverage (253 species, 174 gene
