THE FOREST OF Day IS A MISTAKE. IT LIES IN DJIBOUTI, a hot desert country in the Horn of Africa, where temperatures can rise into the 40s and where the landscape is made of volcanic rock. The vast majority of Djibouti is a dustbowl. But when its landscape formed millions of years ago and tectonic plates collided, part of it was thrust so high into the air that it penetrated a cooler airstream. Reaching over 2,000m high, Djibouti's mountaintops are the exception to its desert climate. Its peaks are bathed in wet clouds, allowing for a forest to grow. Here, there are evergreen trees, such as olives and junipers, many animals, including leopards and antelopes, and a vanishingly rare bird known as the Djibouti spurfowl.
The forest is called the Forest of Day, and it sounds miraculous, sitting as it does above a high barren desert, but it's doomed. Djibouti has become hotter in recent centuries, with its mountainsides drying up, and current rates of climate change are intensifying that heat further. So the Forest of Day - which, on a geological timescale, has only just come into existence - is already collapsing. Droughts are increasing, and any animal that can leave is moving away.
The Djibouti spurfowl, which cannot leave because it needs forest cover to survive, has become Critically Endangered, chained to a dwindling forest. More than 90 per cent of the population has already vanished, and 200-500 individuals remain.
Like I said, the Forest of Day is a mistake. Its growth period was a mere blip in climatic time. If it disappears, the birds disappear with it.

Jump Around - Bagheera Kiplingi - The acrobatic spider with a predilection for veggie food
Spiders eat flies, right? everyone knows that the 45,000 or so spiders in the world are all obligate carnivores, more or less – eating other animals, mainly invertebrates. Nature, however, loves an exception, and one particular spider missed out on that ecological memo. It goes by the wonderful scientific name of Bagheera kiplingi, and its claim to fame is that its diet is – at least mostly – vegetarian.
Female of the Species - Zebras - A strong sisterhood is key to staying safe
Zebras are masters of confusion. Their collective noun is ‘a dazzle’, which is fitting since their bodies and behaviour have been surprising scientists for centuries.
See It, Save It? - Wildlife tourism can be a powerful ally in protecting nature - but it can also harm it. We weigh up the pros and cons.
The sums of wildlife travel aren’t as simple as more tourists equals happier nature. How much did my visit really contribute to the conservation of Lady Liuwa and her habitat – and was that outweighed by carbon emissions from my flights? Did my presence disturb the animals’ natural behaviour more than it reduced the threat of poaching or benefited local communities?The question of whether wildlife travel is, on balance, good for wildlife is a complex one – and there’s no simple answer.
Can Your Really Offset Emissions? - Planning an overseas wildlife-watching trip entails facing some inconvenient truths
Imagine (or maybe you don't need to) that you hanker after the safari trip of a lifetime in sub-Saharan Africa. A 17-day tour beginning at the iconic Victoria Falls, passing through Zimbabwe, Zambia, Malawi and Tanzania, taking in some of the continent’s most wildlife-rich national parks, and ending on the lush island of Zanzibar.
