The first survey planes to fly over Gorongosa National Park after Mozambique’s civil war found a landscape that looked intact and was, in fact, nearly empty. The 1994 count — the first since the fighting began — logged about 7,000 animals in a park that had held vast herds: roughly 100 elephants, 100 waterbuck, a handful of zebras.
Gorongosa, at the southern tip of the Great Rift Valley, had been one of Africa’s most celebrated parks — the safari jewel of Portuguese East Africa. Then came 15 years of civil war, 1977 to 1992, fought partly across the park itself. Soldiers shot elephants for ivory to buy arms and everything else for rations; after the peace, hungry people and commercial poachers finished the job with tens of thousands of snares. By the standard accounting, about 95 percent of Gorongosa’s large wildlife was gone — a greater-than-90-percent collapse in total biomass, confirmed later in the scientific literature.
Greg Carr saw it from a helicopter in 2004 and drew an engineer’s conclusion. “If the fundamentals of the ecosystem are in place,” he reasoned — the rivers, the lakes, the forests, the grasslands, all still there — “we can bring back animals.”
The philanthropist who moved in
Carr was an unlikely candidate for the job: an Idaho-raised entrepreneur who had made his fortune in voicemail — co-founding Boston Technology at 26 — and walked away from his for-profit boards in 1998 to do human-rights philanthropy. Invited by Mozambique’s government to help with its ruined flagship park, he chose the deepest possible version of involvement.
In 2008, after three years of groundwork, the Carr Foundation and the government signed a 20-year public-private partnership to co-manage and restore Gorongosa — an almost unheard-of structure at the time, a national park run jointly with a foreign philanthropist, with Carr pledging roughly $40 million over the long haul. He has since blown through his own pledge many times over; accounts put around $100 million of his personal funds into the project, alongside donor and aid money.
The restoration itself was less Noah’s Ark than police work and patience. Rangers were hired and trained by the hundred; some 27,000 snares and traps were pulled out of the bush. A few species were trucked in to restart bloodlines — buffalo and wildebeest from South Africa, painted wolves in 2018 — but Carr resists the word “rewilding” for a reason he states plainly: probably 95 percent of Gorongosa’s restoration happened naturally. Stop the killing, and the survivors compound.
The count
Compound they did. The park’s aerial surveys — actual counts from the air, not extrapolations — charted the curve: tens of thousands by the mid-2010s, and in 2022, more than 100,000 large animals counted, despite the survey covering only 59 percent of the park. From 7,000 to six figures in under three decades; total biomass now rivals the pre-war park. Lions have multiplied, leopards and hyenas have returned, elephants number in the high hundreds, and the research program — anchored by the E.O. Wilson Biodiversity Laboratory, named for the great biologist who adopted Gorongosa as his window on eternity — has documented nearly 8,000 species, some 200 of them new to science.
The honest asterisk belongs in the ledger, because the park’s own scientists put it there: recovery has been dramatically lopsided. Waterbuck — a mid-sized antelope that breeds fast and fears little — exploded past 55,000 and came to make up nearly three-quarters of the park’s large-herbivore biomass, while the pre-war giants — elephant, hippo, buffalo — that once dominated now hold a fraction of their old share. The animal mass is back; the pre-war mix is still assembling itself, a decades-long question the ecologists are watching in real time.
The other half of the deal
What made the 20-year contract genuinely novel, though, was who else it covered. Some 200,000 people live around (and inside) the park — Carr wrote into the agreement that no one would ever be forced out — and he concluded early that the park would have to work for them or not at all: the people he met in 2008 were, in his words to 60 Minutes, wearing rags and eating insects to survive.
So the Gorongosa Project became, in equal measure, a rural development agency: 1,600 employees, making it the region’s largest employer; programs in all 89 primary schools surrounding the park; health care networks, girls’ clubs to keep students in school, and shade-grown coffee planted with farmers on Mount Gorongosa, sold internationally to fund the mountain’s reforestation. The model worked well enough that in 2018 Mozambique extended the partnership another 25 years — the 20-year bet renewed to mid-century before its first term even expired.
Which is the real headline hiding in the aerial counts. The animals, given peace, restored themselves; that is what Carr keeps insisting, and the 100,000 count is mostly nature’s own arithmetic. What the money and the decades actually bought was the peace — rangers instead of snares, salaries instead of poaching, schools instead of subsistence — a hundred million dollars spent, in effect, convincing one valley in Africa that a live park is worth more than a dead one. The valley, on the evidence, is convinced.
