The playful and pudgy mammal that went viral from its Thai zoo enclosure has a tragic story to inform about her fellow hippos.
Moo Deng is the two-month-old pygmy hippo who flicks her ears in pleasure and likes splashing in water. She lives the lifetime of a celebrity at Khao Kheow Open Zoo, the place big crowds have massed – however the possibilities of recognizing her kin within the wild are slim.
Pygmy hippos (Choeropsis liberiensis) are endangered and estimated to quantity fewer than 2,500. Their decline has been drastic: a long-term survey in a nationwide park in Ivory Coast discovered 12,000 pygmy hippos in 1982; 5,000 in 1997 and a couple of,000 in 2011. In the present day, these hippos are scarce throughout their native west Africa.
Maybe it’s not shocking that pygmy hippos really feel most snug deep within the forest. Early European explorers to Liberia wrote in their diaries that this hippo chooses to forage at night time and conceal itself within the water or in dense vegetation throughout the day.
So secretive is that this species that Nineteenth-century explorers noticed: “if somebody walks throughout considered one of their paths or tunnels (used to navigate via thick vegetation), they’ll abandon that route for some time.”
Delicate souls
Widespread deforestation and fixed disturbance have made it troublesome for pygmy hippos to outlive, requiring as they do a mixture of dense forests and swamps which already restricted them to a small space. West African forests have misplaced over 80 per cent of their unique space, which confines wild pygmy hippos to small spots in Gola Nationwide Forest (Sierra Leone) and Sapo Nationwide Park (Liberia).
With their forests quickly disappearing, there merely isn’t sufficient house for pygmy hippos to seek out meals, thrive and reproduce. A survey within the Gola rainforest and its environment revealed that many have been hiding on former cropland outdoors the protected space.
Cocoa manufacturing might be the largest trigger of forest loss, then gold mining and unsustainable logging. These actions now encroach on forest reserves and different supposedly protected areas.
Earlier forest conservation efforts have failed. Conservationists argue for a system to financially reward farmers and authorise native forestry communities to safeguard the forests and sustainably handle what stays, versus a top-down mannequin of state administration and enforcement.

A world treasure
West Africa’s forest loss is especially heartbreaking as analysis exhibits {that a} remaining patch could also be the best on Earth, surpassing even the Amazon rainforest.
Significantly productive forests harness extra of the solar’s vitality and switch it into a lot of palatable herbs and juicy fruits – extra meals to help animals like pygmy hippos, and so foster wealthy biodiversity.
Earlier than in depth fieldwork starting in 2016, researchers had underestimated the worth of west African forests, significantly their capability to retailer carbon and thereby offset world warming. This oversight was partly the results of these forests being hidden by clouds, which makes satellite tv for pc remark troublesome, and their relative neglect by western researchers in contrast with different ecosystems elsewhere.
It’s not simply Moo Deng’s wider household that’s in danger. West African forests are residence to greater than 900 fowl species and practically 400 mammals – greater than 1 / 4 of all mammal species in Africa. Their future is extremely threatened by in depth deforestation.
Underestimating the worth of west African forests has saved them off the precedence record for world forest restoration. It’s sadly not shocking that deforestation continues. In 2022 alone Ghana misplaced 44,500 acres of forest (twice the dimensions of Manchester), near a 70 per cent enhance from 2021.
Every tropical forest contributes irreplaceable biodiversity. From the elusive mammals of west Africa to the colourful birds of south-east Asia, these ecosystems are equally necessary. Complete plans are wanted to revive them which contain empowering native communities to handle their long-term well being.
A worldwide initiative to designate 30 per cent of Earth’s land and ocean as protected by 2030 (often called 30×30) mustn’t preserve an unlimited space in a single or two locations, ignoring Earth’s different biodiversity hotspots. The lesson of Moo Deng’s disappearing residence needs to be to worth ecosystems equally – and plan their preservation with equal care.
