The number of rhinos in Africa increases for the first time in more than a decade

There was a 5% increase in the number of rhinos sighted in Africa last year, the Conservation Union (IUCN) said today in an announcement to coincide with World Rhino Day.

The number rose to 23,300, although the animals are still endangered by poachers.

"At least 551 rhinos were killed illegally on the African continent last year," according to the IUCN.

The animals are hunted for their horns, which in some regions are thought to have healing or strength-enhancing powers, despite scientific research proving otherwise.

"The number of white rhinos increased to around 16,800 for the first time since 2012," according to the data.

The number of black rhinos also increased, to around 6,500, which the IUCN attributes to stricter conservation measures.

Rhinos are important for biodiversity as they provide safe habitats for other animals.

IUCN is an umbrella organization with active members in the field of nature conservation.

This includes states and governmental and non-governmental organizations.
