What is hotspot explain the importance in biodiversity?
These areas that are particularly important for biodiversity conservation are called biodiversity hotspots. Two things are crucial when determining that a place is a biodiversity hotspot: (i) the number of different species there; and (ii) whether species in that area are endangered or currently being destroyed.
Why is the California Floristic Province important?
The California Floristic Province is a world biodiversity hotspot as defined by Conservation International, due to an unusually high concentration of endemic plants: approximately 8,000 plant species in the geographic region, and over 3,400 taxa limited to the CFP proper, as well as having lost over 70% of its primary …
What is hotspot in ecology?

How many hotspots are there in the world in 2021?
Therefore, according to Conservation International (https://www.conservation.org), at present, there are 36 biodiversity rich areas in the world that have been qualified as hotspots, which represent just 2.5% of earth’s land surface, but support over 50% of the world’s endemic plant species, and nearly 43% of bird.
What are hotspots and Coldspots why it is important in biodiversity management?
Hotspots and coldspots allowed us to distinguish a proactive and a reactive approach to forest management. The proactive approach prioritises coldspots, areas that show low levels of threat and high levels of biodiversity (Bryant et al. 1997), ES or both.
When identifying hotspots around the world Why is it important to simultaneously?
Conservation International requires that areas it identifies as hotspots contain at least 1,500 endemic plant species. By conserving plant diversity, the hope is that we will simultaneously con- serve animal diversity, especially for those groups, such as insects, that are poorly cataloged.
Why is the Caribbean island a hotspot?
The Caribbean islands hotspot supports an important biodiversity within its diverse terrestrial ecosystems with a high proportion of endemicity making the region one of the world’s greatest centers of biodiversity. It includes about 11,000 plant species of which 72% are endemics.
