Designing biodiversity priority areas requires measuring biodiversity using surrogates like species assemblages. Systematic procedures, including complementarity, help select areas to represent biodiversity features effectively for conservation.

Area of Science:

  • Conservation Biology
  • Ecology
  • Environmental Management

Background:

  • Biodiversity priority areas are crucial for regional conservation.
  • Effective selection requires measuring biodiversity and setting clear goals.
  • Measuring all biodiversity is impossible, necessitating the use of surrogates.

Purpose of the Study:

  • To discuss methods for measuring biodiversity and setting conservation goals.
  • To evaluate the strengths and weaknesses of different biodiversity surrogates.
  • To describe systematic procedures for implementing biodiversity representation goals in priority area selection.

Main Methods:

  • Utilizing biodiversity surrogates such as taxa subsets, species assemblages, and environmental domains.
  • Applying systematic procedures that incorporate complementarity to assess area contributions.

  • Estimating irreplaceability and flexibility to account for substitutability of areas.

    • Main Results:

    • Different biodiversity surrogates have varying strengths and weaknesses for conservation planning.
    • Systematic procedures effectively guide the selection of areas for biodiversity representation.
    • Complementarity, irreplaceability, and flexibility are key metrics in priority area selection.

    Conclusions:

    • A combination of biodiversity surrogates is often employed in practical conservation.
    • Representing chosen biodiversity features at an agreed level is an achievable goal.
    • Priority setting must consider complementarity, irreplaceability, flexibility, persistence, and vulnerability.
