Definition of conservation
the maintenance of biodiversity through human management
What does conservation involve?
-the management of ecosystems so that nature all resources in them can be used without running it
-reclamation (process of restoring ecosystems that have been damaged or destroyed)
-diversity between species
-maintenance of a habitat
-sustainable development
Definition of preservation
protecting an area by restricting or banning human interference, so that the ecosystem is kept in its original state
What does preservation include?
- preserving ecologically, archaeologically or palaeontogically sensitive resources
-managing visitation
Argument against preservation
-no one is able to enjoy area
What is the economic importance of conservation?
-provide resources that humans need to survive and to provide an income

-many believe that we should not have the right to decide which organisms can survive, and which we could live without
-we have a moral responsibility for future generations to conserve the wide variety of existing natural ecosystems
What is in-situ conservation?
conservation efforts within the original habitat
Examples of in-situ conservation
-conservation areas
-orangutang islands
-national parks
-biosphere reserves
Advantages of in-situ conservation
-behavioural instincts stay the same
-conserve large number of individuals
-conserves a large biodiversity
-implications from other species
-ecotourism
Disadvantages of in-situ conservation
-issue may still be there
-locals need to be on board
-need to take into account immigration and emmigration
-new issues may develop
What is ex-situ conservation
removing species, help breeding, preserve issues and reintroduce
Examples of ex-situ conservation
-aquarium
-zoological parks
-botanical gardens
-gene bank
Advantages of ex-situ conservation
-removes them from further danger
-allows population size to increase before reintroduction
-brings in more funding and education
