Here's the readers digest for the 2009/10 flights for mule deer in the EK:
"Snow conditions were poor in Creston but excellent in the East Kootenay during surveys. We
observed 146 mule deer in MUs 4-06 and 4-07 (88 does, 36 fawns, 17 class II bucks and 5 class
III bucks) in 222 minutes survey time.
Buck ratios of 23:100 does (90% CI: 3-44) were estimated
for these MUs using the mule deer model. We observed 238 mule deer in MU 4-21 (110 does,
34 fawns, 40 class II bucks and 8 class III bucks) in 155 minutes survey time and
estimated ratios
of 40 bucks:100 does (CI: 29-46). A total of 183 does, 58 fawns, 30 class II bucks and 17 class III
bucks were observed in MU 4-22. Survey time was also 155 minutes.
Estimated buck ratios
were 32:100 does (CI: 16-2
. We observed the most mule deer in MU 4-02 (183 does, 58
fawns, 30 class II bucks and 17 class III bucks) in 325 minutes survey time,
although buck ratios
were low (20:100 does [CI: 12-28]).
Overall buck ratios for East Kootenay MU’s combined were
29:100 does (CI: 14-44). Estimated fawn ratios were slightly higher in the Creston area (45
fawns:100 does) than the East Kootenay (29-34 fawns:100 does), although confidence intervals
overlapped for all areas.

Readers digest for last December's flights... done by some Stent guy?.......
"We observed 842 mule deer, including 514 does, 157 fawns, 34 ≥4-point bucks and 115 <4-point
bucks over 12 hours and 45 minutes survey time. Raw buck:doe ratios
(no sightability correction)
were
33:100 in MUs 4-06 and 4-07 combined (90% CI: 22-39), 23:100 in MU 4-21 (CI: 17-30), 41:100
in MU 4-02 (CI: 34-4, 45:100 in MU 4-22 (CI: 37-52) and 5:100 in MU 4-03 (CI: 1-9). There was a
significant decrease in buck ratios from 2009/10 ratios in MU 4-21, while buck ratios increased
significantly in MU 4-02 and 4-22, although 2009/10 buck ratios were likely underestimated in the
former survey as it occurred in late December and early January when bucks are usually wintering
in bachelor groups in remote habitat and more difficult to detect. Similarly MUs 4-03, 4-06 and 4-07
were surveyed post-rut in 2010 and bucks could be underrepresented in samples from these MUs."
