BIODIVERSITY HOTSPOT Certain areas that have large numbers of endemic species UNIT 4 • Original developed by Norman Myers in 1988 • A method to identify regions/places where most common extinctions occur and people invest money to save and preserve it • Large regions contain exceptional concentrations of plant endemism and high rates of habitat loss TO QUALIFY AS A BIODIVERSITY HOTSPOT, A REGION MUST MEET TWO STRICT CRITERIA: • Must have 30% or less of its original natural vegetation. The species must be threatened (this means it has to have lost bigger or equal to 70% of its original habitat) • Must have at least 1.500 vascular plants as endemics (this means it must have high percentage of plant life found nowhere else, it’s irreplaceable) WHY DO WE NEED BIODIVERSITY HOTSPOT? • Species are relevant to human because they provide air, food and water • Biodiversity underpins all life on Earth • The map of hotspots match up well with the natural places that most benefit people • The hotspots are home to many vulnerable populations who are dependent on nature to survive • The hotspots are among the richest and most important ecosystem WHAT’S HAPPENING NOW? Todays species extinct at the fastest rate Species aren't evenly distributed around the planet Certain areas have large numbers of species and those found nowhere else Many of these are threatened by habitat loss and other human activities Hotspots have lost around 86% of their original habitat and threatened by extinctions induced by climate change ASIA PACIFIC Large land areas, island dotting the Pacific seas, those 13 hotspot represents important biodiversity. POPULAR BIODIVERSITY HOTSPOTS SOUTH AMERICA Brazil’s Corrode to the Tropical Andes, SA has some of the rich and most diverse life on Earth. EUROPE AND CENTRAL AMERICA Plays host to thousands of acres of important habitat AFRICA Diversity of plant and animal life, most of them are found nowhere else on Earth
