Flood Fuels Wild Rebirth of Disappearing Deer
18 Sep
Summary
- A 1998 flood led to the escape of 36 rare Père David's deer.
- Escaped deer naturally established populations outside the reserve.
- Wild Milu numbers exceeded 500 by the end of 2009.
Père David's deer, or Milu, once extinct in the wild in China, are now the subject of an extraordinary conservation tale. Following a 1998 flood, 36 Milu escaped from the Hubei Shishou Milu National Nature Reserve. These animals, unable to be easily returned due to their movement into swampy terrain, began a journey of natural re-wilding. Researchers monitored the escaped deer as they utilized "stepping stones"—suitable habitat patches within a challenging landscape. These areas facilitated movement and reproduction, leading to the establishment of new populations outside the reserve. By the end of 2009, their numbers had surged past 500. The Milu population experienced a decline due to a disease outbreak in early 2010. By the end of 2012, approximately 300 wild Milu were documented across refuge populations near Dongting Lake. The study identified floods and human disturbance as catalysts for dispersal, with population density acting as a key underlying factor.
