Our goal is to use science-based information to guide elk management in Missouri
Survival (proportion surviving 1 year) and Reproduction (calves per cow) recorded via collar data
|2011-2014||2015-Present||Eastern Elk Populations|
|Adult cow survival||91%||96%||92%|
|Adult bull survival||94%||79%||93%|
|Yearling cow survival||82%||90%||91%|
|Yearling bull survival||91%||88%||85%|
Our ongoing research efforts have documented more than 150 mortalities since the reintroduction of elk in 2011. Around half of these mortalities have been calves, which is the most vulnerable age group. Brainworm is the leading identified cause of death for free-ranging elk in Missouri. Infections, trauma, mountain lions, and a single elk vehicle collision are other forms of mortality for free-ranging elk in Missouri.
