Wildlife Diseases
Alberta has some of the best Watchable Wildlife opportunities in the country. The
diversity of wild life-forms surpasses that in many other jurisdictions and runs
the gamut from ants and antelope to walleye and whiskey-jacks. Many species are
well known and well appreciated for a multitude of benefits. However, others are
seldom seen and often unknown or misunderstood by those who see them or hear of
them for the first time. Parasites and disease agents can invoke some obvious concerns
about whether they are a risk to people, to livestock, or to other wildlife.
By far, the majority of individual fishes and wildlife in Alberta are healthy and
it is a rare event to see sick or dying animals. That said, diseases and parasites
also are a natural part of any ecosystem and the balance among all free-ranging
native species. The following documents provide information about some of the noteworthy
diseases and parasites in Alberta and the programs that have been implemented to
understand and, if necessary, manage them.

CWD Test Results: hunters who submitted heads for chronic wasting
disease (CWD) testing will receive a letter in the mail with the results within
six weeks of submission of the head. Thanks for your assistance - it is critical
in controlling CWD!
Avian cholera has been confirmed in waterfowl near Calgary in February
2007. This is not uncommon in the Bow River watershed among overwintering waterfowl.
It is caused by a bacteria that affects the birds due to poor conditioning caused
by the harsh winter, difficulties finding food, and the stresses of crowded flocks.
The following links provide good background on this disease:
