Biodiversity definition
Biodiversity definition

Strip transect area size
Strip transect area size
10 m long × 1 m wide = 10 m²
Species richness
Species richness
Number of different species in a region
Species evenness
Species evenness
How balanced the populations of each species are
Abundance rating categories
Abundance rating categories
L (Low), M (Medium), H (High)
What abundance ratings measure
What abundance ratings measure
Relative abundance compared to other species in survey
Animal evidence in surveys
Animal evidence in surveys
Animals, footprints, burrows, nests, faeces, feathers
High species evenness
High species evenness
Many species with similar abundance levels
Human impact on biodiversity
Human impact on biodiversity
Greater disturbance = reduced biodiversity
Why measure both richness & evenness
Why measure both richness & evenness
Provides complete picture; same richness ≠ same health
