Pascha is a name taken from a Waler from WW1 (spelling Pasha, also Passchendale from the battle).
Captured on Todd River Downs in 2019 as a result of extensive research into the likely presence of old-boodlines breeding true to this day in the isolated and harsh country but being removed as feral animals so facing extinction in this area.
