The development of equestrian leisure activities in France is in part due to individual amateurs, who own their Equine. This article examines the factors that may influence the more or less high significance of these Equine in rural and suburban areas. The results highlight reciprocal influences between the Equine density and the residential development intensity of these territories. The effects of some sectors are also tested : the influence of the agricultural sector is complex, governed by both competitions and complementarities for land occupation. There is moreover a clear local ripple effect of the equestrian professional dynamic on the presence of these Equine. Finally, this work focuses on the links between the development of equestrian leisure and the current countryside changes and point out Equine of these amateur owners as good revealers and markers of the new rural dynamics.
