in situ conservation Flashcards
(12 cards)
what is conservation
-active management to prevent resources running out
what is preservation
-keeping it exactly as it is
what’s dynamic conservation
-adapting methods to constant ecological changes
what’s reclamation (involved in conservation)
restoring ecosystems so they can be used again
what’s the red data list
-the red list of threatened species
-worlds most comprehensive inventory of global status of plant and animal species
where are conservation efforts centred on the red data list
-critically endangered species
-endangered species
what is in situ conservation
habitat maintenance
examples of in situ (wildlife reserve) active management
-controlled grazing
-restricted human access
-controlling poaching
-feeding the animals to ensure survival
-reintroduction of species
-cull/remove invasive species
-halt sucession
examples of in situ (marine conservation) active management zones
-need to preserve areas like coral reefs against damage from non sustainable fishing
-create areas of refuge where populations can build up and repopulate adjacent areas
-large areas required
benefits of in situ conservation
-maintains genetic diversity
-maintains ability for species to adapt to changing conditions
-preserves interdependent relationships
-generally cheaper
disadvantages of in situ conservation
-area can act as honeypot to poachers and ecotourists who cause disturbance
-endangered habitats may be fragmented + each small area may not be large enough to ensure survival
principles for choosing a wildlife reserve
(1) comprehensiveness- how many species/ prevailing environment
(2) adequacy- is the area large enough to provide long term survival
(3) representativeness- is there a full range of diversity
