Additional objectives were to characterize size, cover type composition, and length of time spent at the birth site by cow-calf pairs.
In 2012 births were verified using helicopter searches to visually observe cow-calf pairs at the birth site shortly after parturition.
We simulated post-parturition locations using GPS data to estimate the distance that cow-calf pairs in the VHF data set were from the birth site based on calving dates from GPS-collared moose in 2012.
If a cow-calf pair was observed, a waypoint was taken to establish the center of the post-parturition area; those cows were not relocated during subsequent search flights.
Defining and identifying specific characteristics associated with the parturition location and post-parturition area is important because this area must support the cow-calf pair for at least 3 weeks.
In February, sic bison -- three cow-calf pairs
-- were shot while five other bison were captured and sent to slaughter.
