African forest elephants decline by 62% in 10 years

African forest elephants face extinction if 'drastic measures' are not taken

Forest elephant numbers have decreased by 62% across Central Africa over the last 10 years, according to a study.

The analysis confirmed fears that African forest elephants (Loxodonta cyclotis) are heading for extinction, possibly within the next decade. Conservationists said "effective, rapid, multi-level action is imperative" in order to save the elephants. They are concerned the forest elephants are being killed for their ivory. Results of the study, undertaken by researchers from the Wildlife Conservation Society (WCS), are published in the scientific journal PLoS One. Over 60 co-authors contributed to the study, which was led by Dr Fiona Maisels, a WCS conservation scientist from the School of Natural Sciences, University of Sterling. "Although we were expecting to see these results, we were horrified that the decline over the period of a mere decade was over 60%," Dr Maisels told BBC Nature.

Elusive giants

Rhinos and elephants: the secret lives of Africa's giants

Rhinos and elephants have a range of remarkable behaviours and adaptations, many of which we are only just learning. Emerging through the twilight, a beast lumbers forward, sniffing, snorting, searching for something. One of the largest animals to walk the earth, it is on a surprising mission. This black rhino is embarking on a midnight journey, seeking out other rhinos in the dark to socialise and mate with, sharing some never-before-seen tender moments.

Because despite their size, we are only just beginning to notice some remarkable behaviours and adaptations of elephants and rhinos. These two groups are the largest terrestrial animals. The three species of elephant range from 5.5 tonnes for an average male African bush elephant to 2.7 tonnes for female Asian elephants.

Rhinos, of which there are five species, can exceed 3.5 tonnes. Their size makes them relatively easy to spot and an easy target for poachers, who continue to hunt both groups of large mammal in significant numbers: elephants mainly for ivory in their tusks and rhinos for their horns. They have all been extensively studied by scientists, in the field and also in wildlife parks, breeding centres and zoos. But much about them, and what they get up to, remains a mystery, with many discoveries into their behaviour and adaptations only being made recently. We are still struggling to understand just how unique are different populations of these megafauna.

Of the nearly forty feline, or cat, species, only one—the domestic cat—is believed to be secure. As undeveloped land becomes harder to find, large cats, such as lions, panthers, tigers, jaguars, and cheetahs, are left with less and less natural habitat in which to live.
