  1. Recapture probabilities are the odds of recapturing a newly released individual. Recapture probability averages are weighted for the number of captures for unequipped individuals, or deployed collars for equipped individuals in the grid
  2. *Coordinates of each trapping grid are presented in degree decimal with the WGS84 geodetic system
