Trumpeter Swans
Trumpeter swans were once widespread and abundant in North America. However, a combination of heavy hunting pressure and habitat lost drastically 4 reduced the species’ population down to less than 70 individuals in the wild by the mid-1930s.

By the mid-1980s, Trumpeter swans were more prevalent again in Alberta, especially near Grande Prairie.

The following graph depicts the estimated number of Trumpeter swans in Alberta, carried out at five-year intervals from 1985 to 2010.

What growth pattern of the Trumpeter swan population in Alberta is being observed?
What environmental conditions allow the growth pattern that you identified?
What may cause the growth pattern that is being observed to change?
