Methods for maintaining biodiversity

• Conservation

  Active management of the environment and its resources to maintain biodiversity
• In situ conservation

  Conserving a species in its normal habitat
• Ex situ conservation

  Conserving an endangered species by activities that take place outside its normal environment (e.g., wildlife parks)
• Legislation can be passed to minimise human impact on the environment to help protect endangered species
• Human activities that can be banned

  • Hunting
  • Logging
  • Clearing land for development
  • Agricultural activities
• Each country has different legislation regarding endangered species
• Some countries have no regulation regarding endangered species
• In some countries, it can be difficult to enforce legislation
• Wildlife reserves

  • Permanently protect biodiversity within that ecosystem
  • Plants and animals are maintained in their natural habitat
  • Allows management of the area to ensure ecological integrity is maintained
  • Opportunity for ecologically sustainable land use
  • Provides opportunities for research
  • Should incorporate the needs of local indigenous people
• Culling

  Removing invasive species that are not native to an area and have negative impacts on the environment or health
• Halting succession is a natural process where early colonising species are replaced over time with a stable mature population
• Maintaining habitats

  Ensures future generations can benefit from biodiversity
• Feeding animals can help ensure more organisms reach reproductive age
• Resolving species issues can involve adding species to areas that have become locally extinct or whose numbers have declined
• Restricting access during breeding seasons can help protect endangered species
• Providing safe spaces for animals can aid in their recovery
• Using legislation can help protect endangered species
• Marine conservation zones

  Areas designated to preserve species and habitats, such as coral reefs, which can be devastated by non-sustainable fishing
• Aim of Marine conservation zones

  To provide areas of refuge so that populations can build up and repopulate adjacent areas
• Reason for large areas in Marine conservation zones

  Target species for conservation often move large distances to breed in geographically different areas
• Crue North Meadow is a National Nature Reserve
• Crue North Meadow

  • Great variety of wild flowers
  • International importance as a prime example of a lowland hay meadow in Europe
• Aims of repopulation schemes

  To restore and increase populations of species
