This small version of the aerial photo is represents the study area of the first few years. The study area expanded after that as additional turtles were found, and turtles were tracked longer distances.
The aerial photo was taken during leaf-off, so the primary green vegetation are pines stands and rhodedendron thickets. Ater leaf fall, the canopy cover is surprizingly open, but still sheltered from wind.
This medium size photo is the core of the study area today. The primary difference between this and the original smaller study area (aside from almost doubling in size) is the inclusion of the area to the west including the clearcut where M13 frequented and hibernated.
(1.563 Km) wide
(1.616 Km) high
Several turtles have been tracked both to the north and to the south of this photo, including transients, and other long distance travelers.
The large photo is the current study area except for M17's (transient) route. Several turtle routes (M20 aqua, M13 blue and yellow, and M22 red) are overlain to show the extent of the turtle travels. The photo dimensions are:
1.1 miles wide
1.8 miles high
As turtles travel longer distances, and into areas not tracked before, larger photos wil be needed to plot the new tracks.
