From lush rainforests to majestic mountains, some regions of Earth are simply irreplaceable. Many of these regions are biodiversity hotspots—areas that are both rich with life and at high risk for destruction.
Biodiversity hotspots make up about 2.3 percent of Earth’s land surface, but 44 percent of the world’s plants and 35 percent of land vertebrates live in these regions. Most plants in a biodiversity hotspot are endemic, meaning they are not found anywhere else on Earth. Yet biodiversity hotspots are, by definition, in a conservation crisis. To be classified as a biodiversity hotspot, a region must have lost at least 70 percent of its original natural vegetation, usually due to human activity.
There are over 30 recognized biodiversity hotspots in the world. The Andes Mountains Tropical Hotspot is the world’s most diverse hotspot. About one-sixth of all plant species in the world live in this region. The New Zealand archipelago is another hotspot. Life on New Zealand evolved in isolation, so the islands contain many species not found anywhere else. More than 90 percent of the insects and 80 percent of the vascular plants in New Zealand are endemic to the region. The Himalayan region contains the tallest mountains in the world, as well as incredible animals found only there, including the giant panda, the wild water buffalo, and the black-necked crane—the only alpine crane in the world. Deforestation and climate change have made the Himalaya a biodiversity hotspot.

Biodiversity refers to the variety of organisms found in a particular habitat. It is important to maintain biodiversity because we rely on it for ecosystem services, which fall into four main categories: provisioning, regulating, cultural, and supporting. The earth provides these to us for free and they are critical to achieving a planet in balance. Use these resources to explore the diverse species that exist across the globe, and encourage your students to become good stewards of life on earth.
Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi. While Earth’s biodiversity is so rich that many species have yet to be discovered, many species are being threatened with extinction due to human activities, putting the Earth’s magnificent biodiversity at risk.
