3. Introduction
A biodiversity hotspot
is a biogeographic
region with significant
levels of biodiversity
that is threatened
with humans
It is the region from

Criteria for
Biodiversity Hotspot
• Area Contain at least1,500
species of vascular
plants(> 0.5 percent of
the world’s total) as
endemics
• Have lostatleast 70
percentof its original habitat

5. History
seminal paper by British ecologist
Norman Myers in 1988 first
identified 10 tropical forest
“hotspots”
In 1990, Myers added a further
eight hotspots, including four
Mediterranean-type ecosystems.
Conservation International
(CI) adopted Myers’ hotspots as its
institutional blueprint in 1989
the organization made the decision
to undertake a reassessment of the
hotspots concept,
Three years later an extensive
global review was undertaken, and
hotspot number increase to 25

6. Continue….
2005
The most recent analysis culminated in
2005 and brought the total number of
biodiversity hotspots globally to 34
2011
In 2011, the Forests of East Australia
was identified as the 35th
Feb. 2016
In February 2016, the North American
Coastal Plain was recognized as
meeting the criteria of Myers et al.
(2000) for a global biodiversity hotspot​,
the 36th.

7. Biodiversity Hotspot of the world
• Currently, 35 biodiversity hotspots have been identified
• The biodiversity hotspots stretched across 15.7 percent
of the Earth’s land surface
• 86 percent of the hotspots’ original habitat has
already been destroyed.
• Today, the intact remnants of the hotspots now cover
only 2.3 percent of the Earth’s land surface.

9. Importance of Biodiversity Hotspot
Home to around 2
billion people,
Hotspots provide
ecosystem services for
human life, valued $1.59
trillion per year
They are home to
60% of earth’s
plant, bird,
mammal, and
reptile, marine
species
Total of 22,022
vertebrate species
occur in the hotpots
(77 percent of the
world's
total)
Provide different
types of resources
Maintains the earth

11. Conservation of Biodiversity Hotspot
• Critical Ecosystem Partnership Fund (CEPF) is a global
program that provides funding and technical assistance to
nongovernmental organizations and participation to protect the
Earth's biodiversity hotspots
• The World Wide Fund for Nature has derived a system called
the "Global 200 Ecoregions", the aim of which is to select
priority Ecoregions for conservation All biodiversity hotspots
contain at least one Global 200 Ecoregion.
• Birdlife International has identified 218 “Endemic Bird Areas.
Birdlife International has identified more than 11,000 Important
Bird Area all over the world.

12. Continue….
• Plant life International coordinates several the world
aiming to identify Important Plant Areas.
• Alliance for Zero Extinction is an initiative of a large
number of scientific organizations and conservation groups
who co-operate to focus on the most threatened endemic
species of the world.
• The National Geographic Society has prepared a world map
of the hotspots and ArcView shapefile and metadata for the
Biodiversity Hotspots including details of the individual
endangered fauna in each hotspot
