^aGroup experience: recently reintroduced (from 2 days up to 3 months after the transport from Europe, fenced area); long-term reintroduced (after 1 year acclimatization period, released); wild-born (born in the wild). One mare in wild-born Azaa harem was born in captivity in Europe and reintroduced to the GGBSPA in 2004
^bCounted as the inter-yearly changes in the number of breeding mares (in %; number of mares present in the herd during the previous and the observation year, divided by the number of mares present in one or another year
^cAverage age of foals (in days) at the end of each selected observation
^dDominant
