Minimum Habitat Area vs Target Number of Species

How to Calculate Minimum Habitat Area

The species-area relationship predicts how many species an area can support.

Formula

S = c * A^z (Species-Area Relationship)

A = (S / c)^(1/z) (Solving for area)

Where:

  • S = number of species
  • A = area (hectares)
  • c = constant (varies by taxon and region, typically 5-20)
  • z = exponent (typically 0.2-0.35)
  • This relationship is one of ecology's most consistent patterns.

    Example Calculation

    Find area needed for 50 species with c=10 and z=0.25.

    1. 01Area = (50 / 10)^(1/0.25) = 5^4 = 625 hectares
    2. 02In acres: 625 * 2.471 = 1,544 acres
    3. 03In km2: 625 / 100 = 6.25 km2
    4. 04Species at half area: 10 * 312.5^0.25 = 42 species
