Thread: Elevation

I'm fairly new to hunting and in my short time out in the hills iv started noticing that once you start to find fresh sign it seems to be about the same elevation. Go 200m higher/lower and the sign seems to become less fresh. Would this corrolate between different ranges/ areas or would this generally be new zealand wide?
I'm keeping records each walk to try and help next year's hunts more successful.

Some times it seems a shame to get to the sign but be halfway up a hill that was intended to be glassed from the top.
Whats others thoughts on this?
