Elephant Overpopulation at Madikwe Game Reserve Is Real, Ignoring It Courts An Ecological Collapse.
By Trevor Oertel
Dr. Adam Cruise’s recent article, “Crisis in Madikwe: Too many elephants or just an excuse to hunt them?”, questions whether the call to manage elephant numbers in Madikwe Game Reserve is grounded in science or merely a cover for commercial hunting. While such skepticism is healthy in democratic environmental debate, Cruise’s critique misrepresents the underlying ecological crisis and overlooks decades of scientific warnings, even from animal welfare and animal rights organizations, that elephant overpopulation poses a clear and present danger to Madikwe’s biodiversity.
Let us be clear, this is not an invented crisis. It is a biological and ecological reality, one that Cruise downplays to the detriment of both the elephants and the broader ecosystem.
Cruise implies there is no scientific evidence to support the claim that Madikwe’s elephants have exceeded carrying capacity. Yet he himself cites a figure of 2.7 elephants per km², one of the highest elephant densities in any fenced reserve in South Africa. Numerous ecological studies have shown that elephant densities exceeding 1/km² in enclosed systems lead to unsustainable pressure on vegetation, particularly on slow-growing woody species.
This is not conjecture. It is the well-established conclusion of decades of research from Kruger, Pilanesberg, and other enclosed reserves where similar density thresholds have resulted in massive habitat conversion from woodland to open grassland within a single generation. Once canopy trees and woodland structure collapse, so do the microhabitats for countless other species.
Cruise dismisses reports of degradation as anecdotal, based on a single site visit after seasonal rains. But the claim that there is “no evidence” of ecological decline is provably false. Aerial photographic comparisons and long-term vegetation monitoring in Madikwe have shown progressive loss of large trees and increased bush encroachment classic signs of elephant-driven structural transformation.
Even the animal rights organisation Humane World for Animals, hardly a pro-culling voice, acknowledged the looming problem as early as 1998. The organization offered free contraceptives to the reserve to control growth humanely, recognizing the population trajectory was unsustainable. They reiterated this offer in 2020 and 2023. It is revealing that even animal rights activists have acknowledged the issue Cruise denies.
Cruise criticizes reserve management for rejecting non-lethal options like contraception, presenting it as a humane, consequence-free solution. But this view ignores the biological limitations and long-term risks of immunocontraceptive programs:
* Contraceptives do not reduce the current population. Even sterilized elephants continue to consume 200 kg of vegetation and 150 liters of water daily.
* Effects on herd structure. Long-term suppression of births disrupts age cohorts and matriarchal knowledge transfer, creating unnatural social dynamics.
* Operational challenges. Administering contraceptives requires darting specific females in vast areas repeatedly, which is logistically complex and prone to error.
Madikwe is not a zoo. It is a semi-wild, fenced ecosystem where ecological balance, not indefinite population maintenance, is the core mandate.
Cruise highlights the 75 elephants that died during the recent drought, calling it a “paradox” that the board still wants to reduce numbers. But this misunderstands population dynamics. A drought-induced spike in mortality does not correct chronic overpopulation, it confirms it. Starvation is a natural cap when artificial boundaries prevent migration.
In fact, using drought mortality to justify inaction is unethical. Waiting for more animals to die slowly and painfully, or for vegetation to collapse beyond recovery, is not a morally superior alternative to a proactive, managed response.
Cruise and others suggest that the solution lies in opening corridors between Madikwe and Pilanesberg to restore historical elephant migration, if there ever even was one. The corridor argument is romantic and conceptually appealing but deeply unrealistic, and the idea crumbles under practical scrutiny.
* The distance between Madikwe and Pilanesberg is over 80 km as the crow flies, crossing mixed-use landscapes that include villages, mines, farms, and major roads.
* A viable corridor would need to be at least 5 to 10 km wide to allow elephants safe, natural movement without escalating human-wildlife conflict.
* It would require significant financial investment for land acquisition, fencing, water provisioning, ecological rehabilitation, and extensive anti-poaching infrastructure to secure safe passage for wildlife.
* More critically, Pilanesberg Game Reserve itself has also exceeded its ecological carrying capacity for elephants, compounding the regional problem.
The idea that Madikwe’s “excess” elephants can simply be shifted into Pilanesberg is biologically and logistically flawed. Pilanesberg does not have capacity to absorb more elephants as it is already under similar pressure, and the situation there is equally urgent so connecting two already overpopulated reserves, offers no ecological relief.
Cruise suggests that the management plan is financially motivated, using elephants as a pretext to expand hunting. But even if hunting contributes to revenue, that doesn’t invalidate the ecological necessity of population reduction.
In fact, well-managed, regulated hunting is a legally recognized conservation tool under IUCN guidelines. If implemented transparently, it can support reserve operations, fund community development, and incentivize local conservation. The conflation of hunting with unethical behavior is misleading and ignores its role in managing carrying capacity where non-lethal tools fall short.
Cruise claims that his business, Endangered Wildlife Investigations, “provide governments, policymakers, and conservation organizations with critical intelligence to drive meaningful change, ensuring that decisions about wildlife are informed by truth — not profit or political agendas.” yet his anti-hunting agenda is well known within conservation circles and if his article “Sport hunters killed Cecil, Zimbabw’s best-loved lion” is an indication, Cruise can be economical with the truth if it gets in the way of his agenda. Cruise by his own admission broke the global story of Cecil the Lion, an unknown, by most, Zimbabwean lion legally hunted in Zimbabwe in July 2015. Cruise acknowledged that his story “sparked international outrage and ignited a global conversation about trophy hunting and wildlife ethics” and cemented his “reputation as a leading investigative journalist in the conservation world.”
Just one consequence of this story was a proposed Bill before the US Congress the “Cecil Act”. Dr. Patience Gandiwa, then the Executive Technical Advisor Zimbabwe Parks and Wildlife Management Authority, from her submission to the House Natural Resources Committee United States House of Representatives stated the following:
“Ceasing the Importation of Large Animal Trophies from Zimbabwe will NOT contribute in any way to the Conservation of Ecosystems, the proposed ‘Cecil Act’ is NOT based on science and is completely ‘out of touch’ with realities of sustainable conservation of Elephants and Lions.”
In written supplementary questions asked of Dr. Gandiwa, by Rep. Rob Bishop after her testimony to the House Natural Resources Committee United States House of Representatives:
“Was the hunting of Cecil the Lion legal?”
Here is Dr. Gandiwa’s written answer of the 1st August 2019 which is crystal clear to the question.
“The hunting of Cecil the Lion was legal as the hunting party had all the paperwork and permissions required for a legal hunt.”
Another question and answer which highlights the conservation benefits of trophy hunting to the regional conservation authorities was:
“How does lion hunting contribute to the conservation of the lion species in Zimbabwe?”
Dr. Gandiwa’s written answer “Lion hunting contributes to conservation of lions as it funds the implementation of the lion conservation strategy at national level and supports community-based conservation initiatives. Recognising the distinction between strictly governed sustainable use of the lion species and illegal exploitation of the same which is linked to international organised crime is important. Responsible hunting of lions is good for lion conservation as it removes the nomadic male lions that are often associated with infanticide.”
The truth behind the legal hunt of this lion does not suit the narrative that Adam Cruise’s as an anti-hunting activist use to drum up support and donations from an ill informed and emotionally charged groomed public. As the Acting Chief Executive Officer Campaign to Ban Trophy Hunting (from May 2023 – Nov 2023 according to his social media account but still advertised at such by DM in an article of the 21st April 2024) Cruise has addressed and asked among others British MPs to ban the import of hunting trophies, undermining the conservation strategy of sovereign States.
Cruise and his ilk must remember “you are free to choose, but you are not free from the consequences of your choice”. Worryingly the consequences of their choice could be the extinction of species, and extinction in forever.
Trophy hunting will help address the overpopulation of elephants in Madikwe but will not be enough to avert a ticking ecological disaster. The magnitude of years of mismanagement and animal rightists interference can only be solved with a long term culling program. Elephant culling is not merely a commercial or political decision, it is a sustainable conservation strategy. Done correctly, culling:
* Reduces pressure on vegetation, allowing habitats and other species to recover.
* Maintains the health and integrity of elephant populations by preventing starvation and ecosystem collapse.
* Provides sustainable economic returns through regulated trade in meat and by-products.
* Upholds Africa’s right to benefit from and manage its own wildlife resources, rather than outsourcing its ethics to external ideologues.
Cruise’s article romanticizes elephants as victims of profit-driven bureaucracy, ignoring the wider conservation responsibility to protect all species, plants, insects, birds, predators, and other herbivores. Elephants are not the only inhabitants of Madikwe. Letting their numbers grow unchecked results in a monoculture of megaherbivores, not a balanced ecosystem.
Culling is not “anti-elephant.” It is pro-ecosystem, a tool reluctantly used when all else fails and delay guarantees further ecological collapse.
The crisis at Madikwe is real. Overpopulation of elephants in a fenced reserve with finite resources is a well-documented driver of habitat degradation and biodiversity loss. Cruise’s article is mischievous as it sacrifices ecological integrity for an emotionally appealing, but scientifically irresponsible narrative.
South Africa’s conservation legacy is built on tough decisions backed by science. We owe it to the entire ecosystem, not just to the most charismatic species, to act with ecological foresight. That includes managing elephant numbers, even when it’s politically unpopular.
Science, not sentiment and personal agendas, must guide conservation. For Madikwe and Pilanesberg, the future of their biodiversity, and their legacy as conservation models, depends on honest science, sustainable policy, and the courage to act in Africa’s own best interest.
