ut now it seems that all

is not well in giraffe-land,

with reports emerging

that they may be staring

extinction in the face.

Why? For starters, thanks to modern

molecular genetics, we have just

realised that what we thought was

one species of giraffe is in fact four,

split into between seven and nine

distinct subspecies. That’s a lot more

biodiversity to worry about.

Even more disturbing is the fact that

giraffe populations are collapsing.

Where once they roamed widely across

Africa’s savannas and woodlands, they

now occupy less than half of the

real estate they did a century

ago.

Where they still persist, giraffe

populations are increasingly

sparse and fragmented.

Their total numbers have

fallen by 40% in just the past

two decades, and they have

disappeared entirely from seven

African countries. Among

the most imperilled is the

West African giraffe (

Giraffa

camelopardalis peralta

), a

subspecies now found only

in Niger. It dwindled to just

Pardon the pun, but it’s time to stick our necks out for giraffes.

We have mistakenly taken the world’s tallest mammal for

granted, fretting far more about other animals such as rhinos,

elephants and great apes.

IUCN Red List confirms: Giraffe are under threat

The iconic giraffe, one of the world’s most recognisable animals and the tallest land mammal, has moved from ‘Least

Concern’ to ‘Vulnerable’ in the newly (end 2016) released International Union for Conservation of Nature (IUCN) Red List

of Threatened Species. Widespread across southern and eastern Africa, with smaller isolated populations in west and

central Africa, new population surveys estimate an overall 36-40% decline in the giraffe population from approximately

151 702 – 163 452 in 1985 to 97 562 in 2015. Of the nine currently recognised subspecies of giraffe, five have decreasing

populations, whilst three are increasing and one is stable. This updated assessment of giraffe as a species was

undertaken by the IUCN Species Survival Commission (SSC) Giraffe & Okapi Specialist Group (GOSG), hosted by Giraffe

Conservation Foundation (GCF) and Zoological Society of London (ZSL).

Recent genetic-based research by GCF, Senckenberg Biodiversity and Climate Change Research Centre and other

partners, suggests that there are four distinct species of giraffe instead of only one, however, the IUCN currently only

recognises giraffe as one species. Should these new genetic findings be confirmed and become widely accepted, this

would likely result in three of the four giraffe species being listed as under considerable threat on the IUCN Red List.

Taxonomy is just one of many gaps that still exist in our overall understanding of giraffe and highlights that they are

indeed Africa’s forgotten megafauna.
