INTRODUCTION
Almost went extinct in the early 1900’s
Largest rodent found in North America
Referred to as Ecosystem Engineers
Teeth contain great
amounts of iron

Considered pests because of dams and tree
removal
Certain dams can break and it can create
floods
Beavers are very territorial
Are monogamous

DISCUSSION
Scent of wolf urine may have weakened
Scent may have driven beavers to build more
so they could keep water to build up for more
protection
Beavers may not recognize scent

DISCUSSION (CONTINUED)
May have realized that it was not living and
continued to work
Did not recognize natural predator and saw no
movement so did not fear

DISCUSSION (CONTINUED)
Spillways water quality evened out with the
lake water flowing into it
The increase in water quality will have a major
impact on organisms living in the stream

Wolf Urine did not deter Beavers
from building their dams in the
spillways
Dams altered water quality in the
spillways
