Hi all,

If you want to count introduced species (which in my personal opinion doesn't 
really make sense), shouldn't you at least apply the "three generation rule" (= 

proven self-sustaining generations)? For long-lived birds like Ostrich, this 
means approximately 30-48 years of proven self-sustaining population. Thus, the 
NSW Ostriches need another 10-28 years to become "tickable".
