Cheetahs are beautiful and speedy.

2
00:00:03,727 --> 00:00:10,049
There once were more than
100,000 cheetahs living in Africa and Asia.

3
00:00:10,084 --> 00:00:15,700
Today only about 10,000 of the animals remain.

4
00:00:15,735 --> 00:00:21,469
Laurie Marker is working to keep cheetahs from disappearing.

5
00:00:21,504 --> 00:00:25,534
“I started working with cheetahs when I lived in Oregon —

6
00:00:25,569 --> 00:00:27,596
and I ran a wildlife park there;

7
00:00:27,631 --> 00:00:29,398
this was back in the early ’70s,

8
00:00:29,571 --> 00:00:32,701
and nobody knew anything about cheetahs
and I was fascinated about them,

9
00:00:32,882 --> 00:00:34,799
and the more people I asked they said

10
00:00:34,834 --> 00:00:37,335
‘when you find out something
about cheetahs let us know

11
00:00:37,370 --> 00:00:40,841
they don’t do well in captivity,
they have a very short life span,

12
00:00:40,876 --> 00:00:44,462
and we’re losing them throughout the ranges in the world.’

13
00:00:44,497 --> 00:00:46,871
So that just made me fascinated and

14
00:00:46,906 --> 00:00:49,067
I wanted to know everything there was about them.”

15
00:00:49,102 --> 00:00:53,499
Dr. Marker traveled to Namibia
to learn more about cheetahs.

16
00:00:53,534 --> 00:00:58,689
The country has the world’s largest wild cheetah population.

17
00:00:58,724 --> 00:01:01,460
“Understanding about how
the cheetah lives is really important.

18
00:01:01,495 --> 00:01:04,253
So understanding its biology and its behavior,

19
00:01:04,288 --> 00:01:09,737
understanding the ecology of it,
which really revolves around where it’s living and,

20
00:01:09,664 --> 00:01:12,805
and how it’s living, and that interfaces with humans.”

21
00:01:12,840 --> 00:01:18,887
In 1990, Dr. Marker created the Cheetah Conservation Fund,

22
00:01:18,922 --> 00:01:23,314
a non-profit group based in Namibia.

23
00:01:23,349 --> 00:01:26,751
Farmers often kill cheetahs

24
00:01:26,786 --> 00:01:30,910
 because they can
attack cattle and other farm animals.

25
00:01:31,999 --> 00:01:35,490
So Dr. Marker started working with farmers

26
00:01:35,525 --> 00:01:39,592
to find ways to help
protect their animals from the big cats. 

27
00:01:41,879 --> 00:01:44,277
In 1994, 

28
00:01:44,312 --> 00:01:48,883
she began telling
farmers about the Anatolian Shepherd.

29
00:01:48,918 --> 00:01:53,249
“This breed has been used for about 5,000 years

30
00:01:53,284 --> 00:01:55,308
to protect livestock from predators.

31
00:01:55,343 --> 00:01:57,556
And they act as a guardian by avoidance —

32
00:01:57,591 --> 00:02:00,584
they bark loudly, they tell a predator that

33
00:02:00,619 --> 00:02:02,007
they’re there protecting the flock,

34
00:02:02,042 --> 00:02:05,349
and the flock will come around the dog

35
00:02:05,384 --> 00:02:08,368
and by the dog barking — the predator doesn’t

36
00:02:08,403 --> 00:02:10,333
want to get hurt — and they will then

37
00:02:10,368 --> 00:02:12,539
avoid those flocks where the dogs are.”

38
00:02:13,775 --> 00:02:18,045
Over 15 years, the Fund has donated more than

39
00:02:18,080 --> 00:02:22,410
400 dogs to livestock farmers in Namibia.

40
00:02:23,786 --> 00:02:26,512
“Since our time in Namibia the population

41
00:02:26,547 --> 00:02:30,102
of cheetahs there was about 1,000–1,500 individuals.

42
00:02:30,137 --> 00:02:34,474
Today it’s probably 3,500 maybe 4,000 cheetahs.

43
00:02:34,509 --> 00:02:36,622
So we’ve been able to really grow the population.

44
00:02:36,657 --> 00:02:40,949
And that’s out of a world population of about 10,000.”

45
00:02:46,359 --> 00:02:50,913
The farmers have reported up to an 80 percent decrease

46
00:02:51,013 --> 00:02:53,097
in farm animal deaths.

47
00:02:55,916 --> 00:02:59,687
Dr. Marker wants to expand the CCF programs

48
00:02:59,722 --> 00:03:03,668
to other countries, where cheetahs once lived.

49
00:03:03,703 --> 00:03:06,864
“If we are not successful we’re going to lose

50
00:03:06,899 --> 00:03:09,599
this amazing species in a very short period of time.”
