Wolves now seldom seen in Denali National Park

From ANIMAL PEOPLE, November/December 2013:

Washington, D.C. – Fewer than 5% of the visitors
to Denali National Park in Alaska who sought to see wolves in 2013
managed to do so, according to data released by Public Employees for
Environmental Responsibility.
In recognition of the exceptional economic value of
wolf viewing in Denali, from 2000 to 2010 the state closed 122 square
miles of lands on the park’s eastern boundary to hunting or
trapping wolves, PEER recounted. In 2010,
when 45% of visitors who tried to see wolves saw some, the
Alaska Board of Game eliminated this no-take wolf buffer. The wolf
population across the six-million-acre park fell from 143 in fall 2007
to just 55 in spring 2013, the fewest wolves known to be in
Denali since 1987.
