Home Range vs Activity Area

100% area = 373538.878 sq m = 37.350 ha = 92.303 acres

95% area = 227180.747 sq m = 22.718 ha = 56.137 acres

75% area = 105854.377 sq m = 10.585 ha = 26.157 acres

50% area = 47963.514 sq m = 4.796 ha = 11.852 acres

25% area = 17174.939 sq m = 1.717 ha = 4.244 acres

Accurate Home Range calculations require the tracking and recording of location points to be consistant. Every day all season, or every 2nd day all season.

These 3 photo maps are of Turtle M1's 2013 tracked travels from emergence to hibernation.

The upper left is an as-tracked route of 87 GPS locations, 2.4 GPS miles and the upper right is the route of the 33 locations if tracked every 5 days, 1.7 miles. The lower left map shows the 14 locations if located every 14 days, and is 0.9 GPS miles in length.

The determining of a turtle's actual Primary Activity Area (Home Range) is largely dependant on the quality, intensity, and consistency of the season's tracking activity, and ultimately, multi-season tracking activity.

What M1's actual traveled route looked like is unknown, since she was not tracked daily. But having thread-trailed her many seasons in the past, the estimated travel distance for this season, might be well over 5 miles.
