My belief is only that you rarely ever need introduced species. The arrogance of old-fashioned introductions is a modern burden.
Fortunately, people were prepared to invest the effort to manage white-faced range maggots here. Bison is still far better to eat.
After 15 years of testing that hypothesis, I like the answer.
Even some of our native species have exploded with populations numbers so large (snow geese as an example) that in the winter range,
many places have no bag limits at all.
Just today, I was reading that the wolf population is so high in the north eastern part of BC (Peace River district) that the 3/year limit
maybe lifted entirely.
Eat more lamb. 2,000 wolves can't be wrong.
