Flashcards in Chapter 14- Endangered Species Deck (24):
1

SARA

species at risk act
-COSEWIC reccomends
-federal cabinet makes decisions
-habitat and species protected
-Peter Kent refuses to sign recovery acts due to oil and gas development

2

COSEWIC

committee on status of endangered wildlife in Canada
-biologists who gives reasons, classifications, and what needs to happen
-politicians have final say

3

Classifying Species- SARA

Extinct
Extirpated *
Endangered*
Threatened*
Special Concern
Data deficient
Not at Risk
NO Status *
*Species at Risk Act

4

Alberta Wildlife Act

-Extirpated/Extinct
-at risk
-may be at risk
-sensitive
-secure
-undetermined
-exotic/alien
-accidental/vagrant

5

Extinct

a wildlife species that no longer exists

6

Extirpated

species that no loner exists in the wild in Canada but exists elsewhere
ex) Grey Whale
Gravel chub
Black footed ferret

7

Endangered

species facing imminent extirpation or extinction
ex) swift fox
-whooping crane
-leather back sea turtle

8

Threatened

species that is likely to become endangered if nothing is done to reverse the factors leading to its extirpation or extinction
ex) wood bison
northern wolffish
short-tailed albatross

9

Special Concern

species that may become a threatened or an endangered species because of a combination of biological characteristics and identified threats
ex) Eastern Wold
Black-tailed prairie-dog
Harlequin Duck
(due to oil/gas and climate change)

10

Data Deficient

NOt enough information is available to determine the species status

11

Extinct Species

-Banff Longnose dace (due to goldfish in hot springs)
-Great Auk- flightless bird
-Blue eyed walleye
-Woodland caribou Dawson's subspecies
Elegrass limpet
-Labrador Duck- killed for feathers in feather trade
-Passenger Pigeon- keystone species- killed for feathers
-Macoun's shining moss

12

Areas with high population density
and agriculture

-have high number of species at risk
due to habitat loss, wetlands loss, human use
human impact= major factor

13

Turtles of Point Peele Island

Map Turtle= special concern
Wood turtle= endangered
Spiny soft-shelled turtle=threatened
Midland Painted Turtle=not at risk
Stinkpot turtle= threatened
Blandings Turtle= threatened
Common Snapping turtle= special concern
Spotted turtle= endangered
why? poaching, pollution, habitat loss, Carolinian ecosystem is endangered

14

Why is Midland Painted Turtle the only one not at Risk

larger niche
more tolerant
more generalized

15

How turtles die

Roads=direct mortality, hit by car
Predators and roads- racoons=generalist species
Contaminants- DDT poisoned turtles and changes strength of egg shells

16

Causes

habitat loss- deforestation
over-harvest- shooting, people eating too much
exotics
pollution

17

Extinction-Prone Species

specialized needs (feeding, breeding, nesting)
-fixed migrations (caribou in North disrupted by Alaskan Pipeline)
-limited distribution- exotic species can kill them all off due to small niche
-economically valuable- black bear organs being poached and sold on the black market
-low reproduction rate- bowhead whale does not reproduce until 15
-incompatible with people
-oil and gas development
-cost/benefit analysis of each species
-co-dependance (muscle and trout)

18

Threats?

1. Habitat Loss
2. Non-natives
3. Over-exploitation
4. Pollution
5. Pest control
6. Collecting
7. Climate Change
* think of solution for each threat

19

Solutions?

-re-create habitat
-antibiotics in feed pile
-control non-native species
-clean up pollution
-create protected area
-cut off illegal trade
-education

20

Other calls to action

-INternational conventions and agencies
-research and monitoring
-habitat protection
-captive breeding
-legal actions

21

CITES

convention on the international trade in Endangered Species

22

In Situ Conservation

conservation of ecosystems and maintenance and recovery of populations in their natural environments
-protect species in natural environment
ex) whooping crane

23

Ex situ conservation

conservation of a species or genetic materials in an artificial environment, away from its natural habitat
ex) zoo- take animals out of natural habitat

24

In 2003

high number of special concern and endangered species
lower extinct and extirpated
