Imagine a Forbidden Area, left to slumber for 100 years, in which lies a ‘Fairytale Valley’,“where diamonds were once so common they could be picked up in handfuls as they gleamed in the light of the moon.”
“The most unspoiled large plot of land left on the planet, and the only arid biodiversity hotspot.” A unique wilderness almost the size of Belgium, of “towering dunes, sea cliffs, soaring inselbergs¹, panoramic views, lonely gravel plains, the fourth largest meteorite crater in the world, and mass flowerings that follow spring rains.” A dramatic landscape of desert, grassland, coast and mountains.
This is the Sperrgebiet National Park. The park surrounding a diamond mine is an industrial exclusion zone where Nature holds sway.
(More about the Sperrgebiet shortly)
We humans have found a million ways to deface the planet. Our expanding cities devour the land, we crisscross it with highways, we strip away forests, and crush it under factories, we gauge out mines. We disfigure it with scars of a magnitude visible from space.
But do our worst, we cannot keep unstoppable Nature at bay forever. And when large industrial complexes for example, set up heavily protected security zones around them to keep unauthorised humans out, Nature seizes the slightest of chances to move right on in. Her healing hands transfigure what we have blighted into havens pulsing with life. Life finds a way to flourish in the most unlikely of places. Not least in industrial exclusion zones.
Introducing the Industrial Exclusion Zones
Possibly the most infamous of them all – the Chernobyl Exclusion Zone
In 1986, the nuclear power plant at Chernobyl exploded and deadly radiation spread for hundreds of miles in smoke and dust, air and water. Every human being was evacuated from within a 30 km radius of the plant, and forbidden to return. An exclusion zone of 4000 km² was created. Fences and radiation warning signs were erected.
But wildlife is no respecter of fences and doesn’t read signs.
CEZ fence and wild dog inside the zone
30 years after the event, John Wendle made a visit to the CEZ for the National Geographic magazine, and wrote of finding “the tracks of wolf, moose, deer, badger, and horses. I counted scores of birds: ravens, songbirds, three kinds of birds of prey, and dozens of swans paddling in the radioactive cooling pond.”
And Ukrainian scientist Sergey Gaschak confirmed, “We have all large mammals: red deer, roe deer, wild boar, moose, bison, brown bear, lynx, wolves, two species of hare, beaver, otter, badger, some martins, some mink, and polecats.” And a score of other mammals including bats, as well as ten or more species of big birds: hawks, eagles, owls, storks, and swans. What a wealth of wildlife!
That was 2015. Now a bang-up-to-date 2019 study agrees – wildlife is abundant in the CEZ. Nature is thriving. Nature has taken over. Because we are not there.
“In the exclusion zone, humans have been removed from the system and this greatly overshadows any of those potential radiation effects.”
But the CEZ may be shrinking. Professor Jim Smith from Portsmouth University has been monitoring its radiation levels since 1990. In the outer regions of the CEZ radiation levels are lower than we would get flying on a plane or having a CT scan. And lower than the natural background radiation in many other parts of the world. In the decades to come, as people start to move back into the zone, what will happen to the fabulous wealth of wildlife that has so flourished in their absence?
Even in active industrial installations Nature finds a way
The Secunda Synfuels Operations plant, South Africa
The securely-fenced compound of the Secunda Synfuels Operations plant has become an unexpected haven for servals. The servals have found Secunda’s exclusion zone such a great place to live that the ratio of serval numbers to area is “far greater than any other site on record across the entire range of the species.”
Happily for the servals, the compound intended to keep people out, encircles a large area of wetland. Wetland means a plentiful supply of rodents, and no prizes for guessing servals’ favourite food!
Jwaneng, Botswana
There is little more commercially valuable and well-protected than diamonds. The Jwaneng diamond mine produces 11 million carats of diamonds per year, making it the richest diamond mine in the world. To get those precious stones, nearly 47 million tons of rock and ore are dug out every year. That is one big ugly scar on the face of the planet.
But the Jwaneng exclusion zone also encompasses the Jwana Game Park, home to the globally threatened lappet-faced vulture. Red hartebeest, impala, springbok, steenbok, duiker, wildebeest, gemsbok (oryx) kudu, eland, giraffe, zebra, warthog, baboon, cheetah, ostrich, leopard, caracal, and many other smaller animals are thriving in Jwana.
Venetia, South Africa
The Venetia diamond mine tells a similar story. South Africa’s biggest producer of diamonds, Venetia’s exclusion zone, all 360 km² of it, became the Venetia Limpopo Nature Reserve, notable for those most ancient of trees, the baobabs.
Three of the ‘big five’, lion, elephant and leopard live there in safety, as well as “a broad array of large mammals such as African wild dogs, and cheetahs”.
Humans out, wildlife in.
Now to the Sperrgebiet, Namibia
German speakers will know that ‘Sperrgebiet’ means ‘Forbidden Area’. It lies within what was in 1908 – when diamonds were first discovered there – the colony of German South West Africa. The Forbidden Area, closed to the public for a century is now a national park extending over 26,000km². A national park with a difference, since nearly all of it is still forbidden to visitors. Though to this day diamonds continue to be mined there on a small-scale ,“the habitat is largely untouched and pristine.” It is a true wilderness.
Ancient signs still remain: “Warning. Penalty £500. Or One Year’s Imprisonment. The Public Is Warned Against Entering The Prohibited Area.”
“Exclusion of humans has helped preserve the natural biodiversity of the region which is now a hot-spot for exotic flora and fauna. The Sperrgebiet has more biodiversity than anywhere else in Namibia, supporting animals such as the gemsbok, springbok, and brown hyena, and bird species such as the African oystercatcher, the black-headed canary, and the dune lark. Some 600,000 Cape fur seals live here, representing 50 percent of the world’s seal population.”
80 terrestrial mammal species have been recorded there, and reptile species are abundant.
As for the flora:
- There are 776 types of plants in the Sperrgebiet
- 234 of them are only found in southwest Namibia, an area known as the Succulent Karoo.
- The Succulent Karoo holds the world’s richest flora of succulent plants, with one-third of the world’s approximately 10,000 succulent species
- 40% of its succulent plants are endemic to the Karoo
- With 630 recorded species, the region is also exceptionally rich in geophytes²,
- 284 of the Sperrgebiet’s plants are on the IUCN’s Red List of Threatened Species
The Sperrgebiet is in the world’s top 25 biodiversity hotspots. Man out, Nature in with a vengeance!
The problem is of course that where there are wonders of Nature, people want to see them for themselves. In 2007 the park management were “plotting ecologically sensitive guided driving and hiking trails. Given the importance, but also the fragility, of this ecosystem, tourism planning must out of necessity be carefully and sensitively addressed. Some areas with a high endemicity and range-restricted species are to be designated as Strict Nature Reserves and will never be generally accessible. Other areas will have access limited to visitors on foot, horse or camel back.”
Fine words, and let us hope they will always be born out on the ground³. Otherwise the Sperrgebiet may not remain the forbidden, undisturbed paradise it has been for so long.
But let’s end on an up note. I love this story – Elephant seals reclaim Drake’s Beach in California during the US government shut down. No heavy industry here, but normally lots of humans, including the 85-strong staff of Point Reyes National Seashore. The government shutdown left only 12 staff there, not enough to shake blue tarps to frighten the seals away as they normally would. Every cloud, as they say …
“In January 2019, elephant seals occupied the section of Drakes Beach adjacent to the Kenneth C. Patrick Visitor Center, and, at times, the parking lot and wooden ramps leading up to the visitor center”. The elephant seals – nearly 100 of them – are mostly females with their pups, but there are a few males too.
When the seals showed up, staff promptly closed off the entire area to the public. Now they are experimenting with weekend opening of a small part of the car park, just enough for 20 cars, for supervised viewing only. If the scheme is a success, weekend viewings will continue until early April when the pups will be weaned and the seals will move on.
Drake’s Beach is a far cry from Chernobyl – or Secunda and the diamond mines if it comes to that. But the moral of the story in all cases is the same:
In the words of Point Reyes’ chief seashore wildlife ecologist Dave Press,
“If you just get out of the way, wildlife will find its way in.”
Never a truer word.
¹Inselbergs are rock hills/mountains that arise steeply from a surrounding plain. Inselberg translates as ‘island mountain’.
²Most geophytes are plants that store water and carbohydrates underground – think tuber or rhizome such as the ginger we buy in a store. This underground organ helps them to withstand extremes of temperature and drought and protects them from grazing animals.
³Nowadays there is a strictly controlled guided day tour to Pomona, a ghost town abandoned at the end of the diamond rush, and the famous Bogenfels, a 55 metre high arch of rock on the Sperrgebiet’s Atlantic coast.

Life will find a way; unfortunately, some of that “life” alwaysalwaysalways finds a way to destroy. Humans take advantage of life by using it to destroy. 😦 Great article.

Spot on Stacey! Though I do love the irony that for once, with the diamond mines especially, Man’s greed has had the unexpected effect of making space and sanctuary for Nature.
