FIG. 2 in On the Road Again: Assessing the Use of Roadsides as Wildlife Corridors for Gopher Tortoises (Gopherus polyphemus)

FIG. 2. Details of the two distinct sites within Kennedy Space Center, USA, used for the different parts of this study where (A) and (B) correlate to the study sites outlined in Figure 1. (A) Map of the study site where current roadside corridor use was determined via radiotelemetry of tortoises captured along the roads. Eight example minimum convex polygon (MCP) home ranges are colored showing movement confined to areas along the corridor but no movement directly through the corridor. Tortoise 5221 was the only individual observed moving from the corridor to coastal strand habitat over a distance of 500 m. (B) Map of the study site where we assessed the feasibility of roadsides to function as movement corridors. We translocated tortoises (dotted colored lines) from either inland or coastal habitat into the potential corridor. Daily radiotelemetry (solid colored lines) determined if tortoises used corridors rather than straight-line paths to return to their original home range.
