Digitizing Nature: A Race Against Species Extinction

Less than 16 percent of the world's herbarium specimens have been digitized and shared, with the majority of these un-digitized collections residing in less affluent nations. This digital disparity highlights an urgent need to support these "silent herbaria" to prevent species extinction.

Researchers are now leveraging digitization and artificial intelligence to analyze plant and fungi specimens, transforming conservation science. Historically, specimens were pressed, dried, and stored, holding vital data on location and bloom times. Millions of these specimens are now being digitized and shared globally, offering a clearer view of the planet's vulnerable flora.

AI is proving instrumental in parsing these digital records. One study utilized AI on 8 million digital specimens to track shifts in flowering times due to warming temperatures, discovering an average advance of over two days per decade in the last century.

However, significant digital gaps persist, particularly in Nigeria, where only about 7 percent of specimens are digitized, yet these records are already providing new insights, such as the medicinal plant Cnestis ferruginea having a larger known distribution. Experts call for increased resources for these "silent" collections, warning that without them, many species could be lost to extinction.
