Of the 223 carcasses found,170 (76%) were older and 53 (24%) were newer, with at least one and up to five carcasses foundon each square mile surveyed. There were also two newer regions in the Fremont-Kramer,which are bisected by Highway 58 (Region FK5 and Region FK6 on Map 3-13). Region FK7 is4 mi 2 and found near “Edwards Bowl.” Only 1 tortoise/mi 2 was observed, so this is more likelyan artifact of the survey as opposed to a regional die-off. The two bisected regions included 32mi 2 in Region FK5 and 19 mi 2 in Region FK6. There were 37 fresher carcasses north of thehighway and 26 to the south; given the similar region sizes, the average number of carcasses pertransect was similar (i.e, 1.7/mi 2 to the north and 1.4/mi 2 to the south). Like the older regions tothe north, there were between 1 and 5 carcasses found per transect. Unlike the older regions, 54of 67 carcasses (81%) found in these two areas were estimated to have died within four years ofbeing found.Given the above observations, areas north of Highway 58, excluding Region FK5, arepredominantly (81%) older die-off regions. Region FK5 and south of Highway 58 are (100%)newer die-off regions.1.4N/A1.5Chapter 3 3-115
