Pie diagrams show the relative frequencies of each
clade in 14 Wildlife Management Units (WMUs). Note that Clade A is confined to
three WMUs in the west of the Island, Clade B shows a gradient
from northwest to southeast, Clade
C is absent from the southeast except on
Merasheen Island, which was introduced from Buchans, and
that the Avalon Peninsula in the extreme southeast is
fixed for Clade D.
