Table 2. Number and composition of individual tortoises by sex during the 2012 and 2013 active seasons, partitioned by average midline carapace length (MCL, in millimeters), MCL standard error (SE_MCL), average utilization distribution area (UD, in hectares) and UD standard error (SE_UD).

Sex 1	Count	MCL	SEMCL	UD 2	SEUD
2012
Female	112	220	19	31	62
Male	146	244	29	64	90
Unknown	43	131	31	32	77
2013
Female	109	223	17	21	32
Male	144	248	26	88	260
Unknown	38	128	31	11	20

¹Tortoises classified as sex = Unknown were overwhelmingly sub-adults too small to be identified as male or female.

²The UD is defined as the area encompassed by the 95% kernel density estimate for each tortoise.
