The recovery of degraded ecosystems often requires decades of work, investment, and planning.
An example of this is the current Samara Karoo Reserve in South Africa, a nature reserve of approximately 27,000 hectares that transitioned from a set of agricultural farms to a sanctuary for wildlife.

The initiative began in 1997, when Sarah and Mark Tompkins acquired several rural properties, bringing together a total of 11 former cattle ranches. The goal was to restore a landscape deeply altered by years of agriculture, intensive livestock farming, and hunting.
Since then, the family has driven an ambitious environmental recovery program that completely transformed the territory and allowed the return of numerous native species.
From intensive grazing to ecosystem restoration
Before reintroducing animals, the first challenge was to recover the region’s original vegetation.
To achieve this, the project leaders worked with conservation specialists and gradually eliminated the presence of sheep and goats, which had exerted strong pressure on the local flora for decades.

With the reduction of grazing, large areas began to regenerate naturally. The recovery of shrubs, grasslands, and other plant species allowed the reestablishment of fundamental ecological processes for the survival of wildlife.
Once the first signs of environmental restoration were observed, a second phase began, focusing on the return of large herbivores that historically inhabited the region.

Among the species incorporated were zebras, antelopes, and kudus, whose presence contributed to gradually rebuilding the natural dynamics of the ecosystem.

The return of cheetahs, rhinos, and elephants
After several years of habitat recovery, the reserve initiated one of its most important milestones: the reintroduction of predators and large mammals.
In 2003, Samara became the scene of the return of the cheetah, a species that had disappeared from the area approximately 130 years earlier.
Later, in 2013, the project leaders managed to reintroduce black rhinos, further strengthening the restoration of local biodiversity.
However, one of the most symbolic moments came in 2017, when a herd of African elephants was relocated to the protected area. The species had not inhabited that region for more than 150 years.
Two years later, in 2019, lions also returned, absent from the ecosystem for more than 180 years.

These incorporations allowed the reestablishment of key ecological processes and brought the reserve’s faunal composition closer to what existed before the expansion of productive activities.
The surprising return of species without human intervention
One of the most remarkable aspects of the project is that not all animals returned through reintroduction programs.
In 2021, monitoring cameras installed in the reserve recorded the presence of a wild leopard, a species that returned to the territory on its own.
Subsequent surveys confirmed that the feline continued to use the area, a fact considered by specialists as a sign of the success achieved in habitat restoration.
The spontaneous presence of large predators is often interpreted as an indicator that ecosystems have regained enough ecological functionality to support wild populations.
A model of ecological restoration in South Africa
Currently, Samara Karoo Reserve hosts more than 60 species of mammals and around 225 species of birds, consolidating itself as one of the most outstanding environmental restoration projects in South Africa.

Elephants, rhinos, cheetahs, lions, leopards, zebras, and numerous antelopes are part of a biodiversity that just three decades ago seemed impossible to recover.
