Résumé

Most studies of home ranges occur over short time periods and may not represent the spacial requirements of long-lived organisms such as turtles. Home ranges of 18 individual Blanding’s Turtles (Emydoidea blandingii) were measured using minimum convex polygons. Annual space use was compared to multi-year space use by individual turtles. We found a significant difference between annual home range size (25.5 hectares) and multi-year (two to six years) home range size (65.7 hectares; n = 18, P = 0.016). Caution should be employed when making management decisions based on short-term studies of long lived species.
