Flashcards in Introductions and reintroductions Deck (70)
What is the purpose of captive breeding?
Normally in tandem with nature conservation/ restoration
What are the only ways introductions or reintroductions can be successful?
If the original threat to the population has been removed
What is the difference between introductions and reintroductions?
Introductions may form new populations
Reintroductions may add to existing populations
What is the ultimate goal of reintroductions?
To establish a viable population that is free ranging in the wild with no management
What is translocation?
It’s a deliberate and mediated movement of wild individuals from one part of their range to another
What are the objectives of reintroductions?
To ensure long term survival of species
To restore natural biodiversity
To promote conservation awareness
What are the three steps in the process of reintroductions?
Planning, preparation and release
Give two examples of pre-release activities
Assessment of taxonomic status
Detailed studies of status and biology of wild species to determine needs
For animals, pre-release activities must take into consideration what?
Adaptations to local conditions
Shelter and food requirements
Predators and disease
For plants, pre-release activities must take into consideration what?
Pests and diseases
Research into previous introductions and reintroductions should be done how?
With contact of experts who have done it before
What is important in terms of the area that introductions and reintroductions should take place?
It should be protected!
Give some examples of the factors of why introductions and reintroductions should take place
Give some more examples of the factors of why introductions and reintroductions should take place
Adverse effects of previous management
It is desirable that source animals are from what?
If the donor populations for reintroductions are captive bred it is important that they are managed how?
Demographically and genetically
If using captive bred animals it is important that what is done in preparation?
Veterinary testing and training
Why should released animals be afraid of humans?
Otherwise they may cause a problem to livestock
Why should there be socio-economic considerations in introductions and reintroductions?
Because they are normally long-term projects that require financial and political support
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
Reintroductions must also have full support from what?
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
You also need the identification of what for planning, preparation and release?
Long and short term indicators
There also needs the security of what for planning preparation and release?
Pre and Post-release what is of major importance?
What is one of the biggest problems with captive breeding?
It can be too successful and therefore release it done without correct habitat restoration
Give an example of a direct method of monitoring post-release
Tagging an individual of the population
Give an example of an indirect method of monitoring post-release
Give examples of the types of studying that can be done from released stock
Demographical, ecological and behavioural
