stop harrassment, injury and separation to adult bison and calves by park department

  yesterday while watching planet green i was watching as the yellowstone park department were moving adult bison and their calves back into park boundaries that has moved to areas of better feeding outside of the park.  they were using a helicopter. men on horseback, and trucks to run the bison back to the park. it was clear to see that these bison and their calves were very scared as to what was happening to them. ther were numerous severe injuries to the calves and separations of calves from their mothers. these scared,severely injured and lost calves will end up falling prey to the bears ,wolves,coyotes and mountain lions,this kind of treatment to the bison is not right and needs to be stopped. the park department say that it is to prevent the bison from spreading brucellosis. if that is the claim then there is nothing from stopping them from treating the bison.
