Amphibian and Reptile Conservation Network. The page contains
some good general information about Blanchard's cricket frog and
its natural history.
For the teacher: This general site gives some very basic
information about the appearance, distribution, and natural history
of the Blanchard's Cricket Frog. Students may also be interested
in looking further into this site and researching other amphibians
and reptiles or into areas of Canada that have been designated
Important Amphibian and Reptile Areas.

National
Recovery Plan for Blanchard's Cricket Frog, sponsored by Environment
Canada's Canadian Wildlife Service, is a very informative site
about the frog recovery program at Point Pelee National Park in
southern Ontario.

the wolf recovery program from its beginning in 1995 to the present.
Students can follow a pack-by-pack listing, read the observations
of wolf watchers in the park, as well as view maps, news, photographs
and other field notes. The student can even take a cyber tour
of the park to learn about wolves.
Frontier View:
Rocky Mountain Elk Foundation site is an American pro-hunting
site, although it does not focus on wolves.
For the teacher: The Rocky Mountain Elk Foundation site
explores the support for hunting. The foundation believes that
hunting is a long-standing tradition and part of our cultural
heritage, and is a sound wildlife management tool.
"Wolf
on the Doorstep of 10th Circuit Court of Appeals: Conservationists,
Legal Experts In Court To Defend Yellowstone Wolves", appeared
in Wolflines, March 4, 2000.

the perspective of "the opposition". Wolflines is a bulletin published
by the Defenders of Wildlife.

Reference
Section, Waterton Park, Alberta gives a good in-depth look
at wolf attacks on cattle and sheep.
For the teacher: The student will be able to judge for
themselves about the controversy of whether or not wolves are
a menace to cattle and sheep from this well-balanced report. The
information is written for a general audience. It presents the
