Interactions between outdoor recreation and iconic terrestrial vertebrates in two French alpine national parks

Abstract

Protected areas manage synergies and trade-offs associated with core missions of nature protection while supporting education, recreation and tourism. In this paper we demonstrate how spatial modelling co-produced with managers can support the assessment of interactions between two cultural services: outdoor recreation and iconic terrestrial vertebrates. In two French national parks (Ecrins and Vanoise) we showed clear seasonal differentiation in spatial patterns for potential iconic vertebrate diversity, recreation opportunities and their interactions. Our first hypothesis that limited access and mobility of recreationists during winter would increase potential wildlife refugia was largely validated for Ecrins. Our second hypothesis that lower but spatially diffuse pressure from recreationists in Ecrins would increase potential interference as compared to more intense but directed activity in Vanoise was consistent with patterns in summer. For winter the spatial concentration of recreation around ski resorts of Vanoise was highly impactful. Across both parks concerns about the expansion of winter activities are legitimate, especially for climate-sensitive species. We also showed the critical role of refuge areas in high valleys (summer) and lower slopes away from tracks (winter), highlighting threats from off-track practices. Beyond regulation our results will support dialogue with the public and professionals based on communication and education.
