Minimum Habitat Area vs Target Number of Species
公式
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:
This relationship is one of ecology's most consistent patterns.
计算示例
Find area needed for 50 species with c=10 and z=0.25.
- 01Area = (50 / 10)^(1/0.25) = 5^4 = 625 hectares
- 02In acres: 625 * 2.471 = 1,544 acres
- 03In km2: 625 / 100 = 6.25 km2
- 04Species at half area: 10 * 312.5^0.25 = 42 species
常见问题
What is the species-area relationship?
The species-area relationship (SAR) is one of ecology's fundamental laws: larger areas support more species. The relationship follows a power law: S = cA^z.
Why does habitat fragmentation matter?
Fragmenting habitat into small patches reduces total species more than losing the same amount of area from a single large patch. Edge effects, isolation, and reduced gene flow all contribute.
What is the 30x30 conservation goal?
The 30x30 initiative aims to protect 30% of land and ocean by 2030. Scientists estimate this level of protection is needed to prevent catastrophic biodiversity loss.
