Over the past centuries, hundreds of species, including dinosaurs, have vanished from the planet, with approximately 880 animal species declared extinct since 1500
Rate of Extinction
Scientists estimate that between 0.01 to 0.1 per cent of all species face extinction each year, highlighting the urgency of conservation efforts
IUCN's Role
The International Union for Conservation of Nature (IUCN) plays a pivotal role in assessing and categorizing species extinction risks
IUCN Methodology
In 2017, the IUCN published a framework to aid scientists in determining the extinction status of species, focusing on available data and conservation priorities
Survey Approach
One method involves exhaustive surveys across the historic range of a species during specific times and seasons, increasing the credibility of extinction reports
Threat-based Assessment
The second approach evaluates the extent and severity of threats faced by species, with habitat loss being a significant factor contributing to extinction risks
Implications for Conservation
Understanding how species are declared extinct guides conservation efforts, directing resources towards species at the highest risk of disappearance
