Continental hotspots…richest in terms of
biodiversity e.g. Cape Floral Kingdom,
South Africa
Large island hotspots…these are home to
diverse and distinctive species which can
include relict fauna
Small island hotspots…Often low in
species number, but have a high
proportion of endemics. Susceptible to
extinction with small numbers.
