New terms are being used to better describe the kinds of deaths that can occur on wild horse gathers:
Acute condition death = animal that dies or is euthanized due to acute injuries or medical conditions brought about by the gather and removal process including those that occur during capture, sorting and holding at the gather site. This term will include animals that die for known or unknown reasons thought to be related to gather activities.
Chronic/pre-existing condition death = animal that dies or is euthanized for reasons related to chronic or pre-existing conditions such as body condition, lameness, serious physical defects, etc. This term will include animals that are euthanized for conditions not brought about by the gather activity.
