Environmental Sciences 11/12 BC Wolf Cull Environmental Sciences 11/12

What roles do species play in ecosystems? Niche – the role species play in ecosystem Include everything that will effect the species survival and reproduction How much water it needs Amount of sunlight Amount of food needed What it feeds on Temperature it needs

Generalist Species Broad niche (like a raccoon) Live in many places Eat a variety of foods Tolerate range of conditions Examples: crows, coyotes, sparrows, white tailed deer

Specialist Species narrow niche (like a Giant Panda) Live in only one type of habitat Eat one a couple types of food Must have a maintained temperature Very sensitive to environmental changes Have fewer competitors in an environment Examples: giant panda

Wolves in BC Watch the linked video Take notes Share notes with table team at the end to bulk up your notes 

What does this data tell us?

What does this data tell us?

Your Task As a table team do some research you have about the current wolf cull Use the ipads to research information about the wolf cull What are the statistics about caribou depletion? What are the issues about wolf population increases? What are BOTH sides of view and what are BOTH sides justification for their stance? What is the history of the BC wolf culls (how did it work in the past)? Share as a class and take notes on the issue and sides of the issue

Ticket Our the Door Journal Entry What is your opinion about the BC wolf cull? Do you think it is necessary to hep sustain the caribou population? Does saving one population justify killing of another? Why or why not?
