A vital aspect of conservation includes discovering unknown species and rediscovering “lost species” not seen in decades. Protecting these creatures, who are often on the brink of extinction, is crucial for preventing further biodiversity loss. The Search for Lost Species Program is aimed at finding species that have not been documented in at least a decade, and sometimes much longer. To date, they have compiled a list of 4,300 plant, animal, and fungi species that are “lost” to science. From this extensive research, our partners have developed a list of the Most Wanted lost species, focusing on those with the highest conservation priority.
