1

What is the purpose of captive breeding?

Normally in tandem with nature conservation/ restoration

2

What are the only ways introductions or reintroductions can be successful?

If the original threat to the population has been removed

3

What is the difference between introductions and reintroductions?

Introductions may form new populations

Reintroductions may add to existing populations

4

What is the ultimate goal of reintroductions?

To establish a viable population that is free ranging in the wild with no management

5

What is translocation?

It’s a deliberate and mediated movement of wild individuals from one part of their range to another

6

What are the objectives of reintroductions?

To ensure long term survival of species
To restore natural biodiversity
To promote conservation awareness

7

What are the three steps in the process of reintroductions?

Pre-release activities
Socio-economic consideration
Planning, preparation and release

8

Give two examples of pre-release activities

Assessment of taxonomic status
Detailed studies of status and biology of wild species to determine needs

9

For animals, pre-release activities must take into consideration what?

Habitat preferences
Adaptations to local conditions
Behaviour
Shelter and food requirements
Predators and disease

10

For plants, pre-release activities must take into consideration what?

Habitat requirements
Dispersal mechanisms
Reproduction
Symbiotic relationships
Pests and diseases

11

Research into previous introductions and reintroductions should be done how?

With contact of experts who have done it before

12

What is important in terms of the area that introductions and reintroductions should take place?

It should be protected!

13

Give some examples of the factors of why introductions and reintroductions should take place

Disease
Overhunting
Over-collection
Poisoning
Pollution

14

Give some more examples of the factors of why introductions and reintroductions should take place

Competition
Predation
Habitat loss
Adverse effects of previous management

15

It is desirable that source animals are from what?

Wild populations

16


If the donor populations for reintroductions are captive bred it is important that they are managed how?

Demographically and genetically

17

If using captive bred animals it is important that what is done in preparation?

Veterinary testing and training

18

Why should released animals be afraid of humans?

Otherwise they may cause a problem to livestock

19

Why should there be socio-economic considerations in introductions and reintroductions?

Because they are normally long-term projects that require financial and political support

20

Why do the attitudes of local people need to be assessed?

Because understanding and support of the local people is crucial to the projects success

21

Reintroductions must also have full support from what?

Government agencies

22

For planning, preparation and release who do you need approval with and in coordination with what?

Government agencies and land owners, in coordination with national and international conservation agencies

23

You also need the identification of what for planning, preparation and release?

Long and short term indicators

24

There also needs the security of what for planning preparation and release?

Adequate funding

25

Pre and Post-release what is of major importance?

Monitoring!

26

What is one of the biggest problems with captive breeding?

It can be too successful and therefore release it done without correct habitat restoration

27

Give an example of a direct method of monitoring post-release

Tagging an individual of the population

28

Give an example of an indirect method of monitoring post-release

Counting (spoor)

29

Give examples of the types of studying that can be done from released stock

Demographical, ecological and behavioural

30

Why should people intervene post-release?

Supplementary feeding, veterinary, horticultural aid
