Why habitats?
Biological diversity is the variation
in nature at all scales: genes,
species, biological communities,
and ecosystems.
Why habitats?
Habitat: all the biotic and abiotic
components that make up the
environment where an organism or
community occurs.

Habitat diversity is a good
surrogate for species diversity.

Effective biodiversity conservation
focuses on
    • species,
    • their habitats, and
    • the landscapes that support
         those habitats.
