Big Game Most big game species underwent population fluctuations since European settlement, with often critically low numbers in late 1800’s early 1900’s, with some recovery since then

Many occur now only in fragments of their historic ranges,

Some have local populations high enough to cause environmental damage

For all species, human-wildlife interactions are increasingly key to population health and survival

Increasing need to think in terms of populations rather than species
