This study examined college students' visits to natural areas on campus and how these visits relate to place identity and environmentally responsible behaviors. The majority (76.5%) of the 115 participants visited the natural areas, and 55.7% of these students visited for a course requirement. Students who lived on campus, were younger, and majored in environmental studies, humanities, or arts made more frequent visits. Among those who had visited the natural areas (n = 88), place identity and environmental responsibility were related to visitation frequency, and were stronger for those who had visited for a course requirement. Place identity mediated the relationship between visiting for a course requirement and environmental behaviors, but did not mediate the impact of visitation frequency. (Contains 4 tables.)
