- - - - Paying hunters to kill animals
      - Poisoning
      - Trapping
      - Introduction of a predator
      - Breeding control
      - Enclosing animals
    - - Removes invasive species that are threatening the environment.
      - The species could be bringing new diseases, killing invasive species, and making some go extinct.
      - If a new predator is introduced to an island, the animals can easily wipe out a whole species.
      - 61% of global eradication has happened on islands.
  - - - Mining - Bioleaching
      - Deforestation
      - Agriculture - Reduction in field boundaries
      - Urbanization
      - Needs total clearance of a specific area before mining; which requires deforestation.
      - Pollution from the machine’s exhausts affects air quality and could cause animal harm.
      - threatens species by -threatens species by- As trees are cut down there is nowhere for birds to build their nests.
        When people move into a new area it can push species out and it also causes lots of new buildings and roads which get rid of the habitat
  - - - Wildlife subsidization, disease transfer, fragmentation, or habitat infringement/loss.
      - Predator
      - Competitors
      - Pesticides and herbicides
      - Introducing alien species
      - Urbanizing area
      - Disease
      - threatens species by -
        
        Hunting or harvesting species faster than natural populations can recover can lead to overexploitation, which may lead to overpopulation of another species, which would decrease other species that could be its prey.
        
        Pesticides reduce the population of pollinators, for example, bees. This results in less pollination and less seed dispersal and less fertilization. The use of pesticides threatens the plant species and the pollinators as they can no longer carry out their role in their interspecies relationship.
        
        Introducing aliens species impacts food chains
  - - - Temperature
      - Nutrient/Oxygen levels
      - Turbulence
      - Light levels
      - water levels
      - thratens species by -Burning fossil fuel releases carbon dioxide into the atmosphere, increasing the earth's temperature.
        Hot water discharged from power stations decreases the dissolved oxygen levels in the oceans
- - - - corodinating global data on biodiversity conservation
      - increase understanding and importance of biodiversity
      - deploy nature based solutions to global challenges in climate food and sustainable development
    - - reasons for changning red list
        
        genuine reason - the threat is no longer present
        
        non genuine - new information has been made availble since the last assesement , There has been a taxonomic revision resulting in the species no longer being the same concept as it was before
      - the red list is an indicator of the world health in biodiversity and groups species from least concern through to extinct , sub levels include endangered
- - - - cost of keeping them in captivity
      - many animals need very specific conditionsor complex species interactions
      - doesnt solve issues with wild populations
  - - - sperm from male is obgained and processed this is then injected into female of same species
    - - female given hormones to release eggs that are then collcted , sperm that has been taken from male and the egg are then fertilised in a lab , the embroyo produced is then planted in another female
    - - temperature - many reptile eggs sex is based on their temp altering this can create desired male to femasle ratios
      - species from tropical areas. may require providsion of heating in order to maximise survival and breeding success
    - - ensure there is a ratio of males oand females that is of a good quantity
- - - - total protection of some species
      - setting limits on numbers
      - having designated sanctuaries where no whaling can take place
    - - to ensure sustanable harvesting of fishing
      - however quotas set to protedt fishes were inappropriate and it failed to prevent the killing of undersized fishes
    - - financil cost
      - can be hsrd to enforce
      - wildlife does not necessairly respect borders
- - - - example- SSSI , local nature reserve ,national trust land
      - local natur resevrve- protects most important areas of wildlife habtat and geological formations in britain
      - SSSI- aims to protect countrys best wildlife and geological sites
      - habitat creation - this involves altering unsuitable habitats so desired species can survive . variety of methods to do this such as flooding abandonded quarries , planting forests , setting u roadside verges
      - habitat managment - used to activiely maintain or enhance a habitat . may involve alteraction of abiotic and biotic factors to suit desired species
        
        some methods involve controlling succesion as a plagio climax
        
        controlling succession- heather- dominated heathlands will rvert to woodland if not managed
        
        example-culling
  - - - example- lundy has different designsated areas such ss red ares which is no fishing or collection of any sea life of any kind
    - - spas - strictly protected sites for rare / vulnerable /migratory birds
      - gives special importance to wetlands of international imporatnace
