 Due to construction of the Westautobahn in the 1960s, a corner in the northwest of the preserve was also lost.This time there was compensation, however, as a portion of the "Laaber Wald", adjacent to the southwest corner, was annexed.Today the Lainzer Tiergarten is home to between 800 and 1,000 wild boar, 200 to 250 fallow deer, approximately 700 mouflons, and 80 to 100 red deer (elk).
