Transcript: Climate Watch Shorts: The changing hunt | May 13, 2017

(music plays)

A black spinning globe appears next to the caption "TVO Climate Change Shorts."

A caption reads "Nam Kiwanuka. Climate Watch Shorts host."

Nam has curly brown hair and wears glasses, black trousers, a black jacket and a long terracotta and red scarf.

Nam says WELCOME TO
CLIMATE
WATCH SHORTS
WHERE
WE EXAMINE THE
LOCAL IMPACT
OF CLIMATE CHANGE.
WOLVES ARE NATURE'S
SURVIVORS,
BUT THE CHANGING CLIMATE IS
AFFECTING THE WAY THEY HUNT
AND THE FOOD THAT
IS AVAILABLE.
WE SPEAK TO WOLF
EXPERTS TO FIND OUT MORE.

An aerial view shows images of a wooded area in winter.

A caption reads "Brent Patterson. Research scientists, Trent University."

Brent is in his forties, clean-shaven and wears a blue puffer jacket, an green scarf and a green woollen hat.

He says THE WOLVES ARE VERY
ADAPTABLE ANIMALS.
AND PRIOR TO EUROPEAN
SETTLEMENT OF NORTH AMERICA,
WOLVES OCCUPIED EVERY
ENVIRONMENT AND ECO SYSTEM
TYPE ON THE CONTINENT.
SO THEY CAN LIVE ANYWHERE.
AND IN THE MODERN CONTEXT
WE KNOW THAT WOLVES CAN
SURVIVE ANYWHERE THAT
THEY HAVE ADEQUATE FOOD
AND PROTECTION
FROM PEOPLE.

Clips show images of a pack of wolves in the wild.

Brent says SO IN THAT SENSE CLIMATE
CHANGE SHOULDN'T HAVE
MANY DIRECT
IMPACTS ON WOLVES.
BUT WHAT CLIMATE CHANGE
WILL IMPACT IS SOME OF
THE PREY THAT WOLVES
DEPEND ON AND SOME OF
THE MEANS THAT WOLVES
USE TO ACCESS THOSE PREY.
DURING THE SPRING
THROUGH FALL,
SOME WOLF POPULATIONS
RELY HEAVILY ON BEAVER.
ONE OF THE POTENTIAL
CONSEQUENCES OF CLIMATE CHANGE
COULD BE WARMER,
DRYER SUMMERS.
AND IF THAT HAPPENS THE
BEAVER HABITAT WILL BE REDUCED
AND BEAVER NUMBERS
COULD BE REDUCED.
SO THAT COULD PUT MORE
FOOD STRESS ON WOLVES.
AND CERTAINLY IN SOME
AREAS OF CENTRAL ONTARIO,
WE KNOW THAT SUMMER IS A LEAN
TIME FOR WOLVES ALREADY,
SO THAT COULD BE A POTENTIAL
NEGATIVE CONSEQUENCE.

The caption changes to "Paul Brown. Wolf centre coordinator, Haliburton Forest and Wildlife Reserve."

Paul is in his late thirties, with short blond hair and a stubble. He wears a beige polo shirt, an army green cap hat and sunglasses over the cap.

Paul says IN THE YEARS I'VE WORKED
WITH OUR WOLVES HERE,
AND WHAT I'VE READ
ABOUT WOLVES FROM
PEOPLE'S DOCUMENTATIONS
OF STUDYING WOLVES, THEY
ARE AN ANIMAL THAT LIKES
TO STAY CLEAR OF PEOPLE.
THEY LIKE THEIR HABITAT,
THEY LIKE THE HARDWOODS,
THEY LIKE THE
CONIFEROUS FOREST.
IT'S THEIR HOME,
IT'S THEIR SAFETY.
AND WOLVES WILL FOLLOW
THEIR FOOD SOURCE.
SO IF THE FOOD SOURCE
IS MIGRATING FROM NORTH
TO SOUTH OR FROM
SOUTH TO NORTH BASED ON
WARMTH, CLIMATE
CHANGE, WHAT HAVE YOU,
THE WOLVES WILL
COMPENSATE.
THEY WILL ADAPT TO
THEIR SURROUNDINGS
WHAT THEY NEED TO DO.

Brent says ANOTHER
CONSIDERATION IS THAT IN THE
WINTER TIME WOLVES MAKE
EXTENSIVE USE OF FROZEN
RIVERS AND LAKES TO
TRAVEL AND TO HUNT.
THIS, IN SOME CASES,
ALLOWS THEM TO PERSIST
AND TO FORAGE EFFICIENTLY
IN AREAS WITH PRETTY LOW
PREY DENSITY BECAUSE
THEY CAN USE THESE
FROZEN LAKES AND
RIVERS TO REALLY TRAVEL
EXTENSIVELY ACROSS
THE LANDSCAPE.
IF THINGS WARM UP
IN THE WINTER TIME
IN THE FUTURE AND THERE'S
A REDUCED AVAILABILITY OR A
REDUCED TIME AT WHICH THESE
LAKES AND RIVERS ARE FROZEN,
THAT COULD REALLY REDUCE
THE TRAVELLING EFFICIENCY
OF WOLVES AND THEIR
HUNTING EFFICIENCY.
AND EFFECTIVELY WHAT THAT
WOULD DO IS SORT OF REDUCE
THE CARRYING CAPACITY FOR
WOLVES ON THE LANDSCAPE.
THEIR ABILITY TO KILL
THESE PREY IS MADE MUCH
EASIER WHEN THERE'S DEEP,
THICK SNOW THAT MAKES IT
HARDER FOR THE DEER AND
MOOSE TO GET AROUND
AND PERHAPS WEAKENS
THE DEER AND MOOSE AS
WINTER PROGRESSES.
SO WARMER, MILDER WINTERS
IN THE FUTURE MIGHT MAKE
THE DEER AND MOOSE LESS
VULNERABLE TO PREDATION
AND, AGAIN, MIGHT MAKE
IT A BIT MORE DIFFICULT
FOR WOLVES TO ACCESS OR KILL
THE PREY THAT ARE THERE.
LUCKILY FOR WOLVES,
THEY'VE DEMONSTRATED THAT
THEY ARE A VERY ADAPTABLE
ANIMAL WITH VERY FLEXIBLE
BEHAVIOURS AND DIETS.
SO RELATIVE TO SOME OTHER
ANIMAL POPULATIONS
I THINK WOLVES
WILL DO FINE.
THE WAY THEY DO BUSINESS,
THE WAY THEY HUNT AND TRAVEL
AND WHAT THEY EAT MIGHT
CHANGE A BIT OVER TIME
WITH CLIMATE CHANGE.
