I am no biologist but just from the numbers you gave I would say Dallas county was basically unchanged if you were to chart it out on an SPC chart but something was possibly causing a negative trend in Winston county. At which time I would use my resources to further investigate Winston county's deer herd and it's health instead of not knowing there may be a problem there until it was too late and would then have to take drastic measures to reverse..... with the data and a little more investigation I may find nothing or I may find I need to adjust something to stabilize or increase the deer population.
