Superpopulation of Wild Boars and Pigs Puts Biodiversity and Public Health at Risk in São Paulo. The Government Launched a Million-Dollar Bid to Monitor, Capture, and Slaughter up to 380 Animals in Conservation Areas. Experts Warn About the Severity of the Problem and the Importance of Technical and Ethical Actions.
Did you know that the Government of São Paulo is offering over R$ 1 million to solve a problem that has been devastating biodiversity in conservation areas across the state? P
It seems like a movie plot, but this initiative addresses an urgent and controversial environmental issue.
Wild boars and pigs, invasive species known for their high destructive capacity, have become a threat to both nature and public health.

But what is the plan to combat this superpopulation? Read on to understand the details of this action and how it may impact the future of protected areas.
The Million-Dollar Initiative Against Wild Boars
The Government of São Paulo, through the Forest Foundation, recently announced a bid that provides for the hiring of services for monitoring, capturing, and slaughtering wild boars and pigs in five conservation units in the state.
The measure, which allocates R$ 1.11 million for the execution of the plan, aims to control the spread of these exotic animals, protect local biodiversity, and ensure the safety of visitors to these areas.
According to the bid, actions will be carried out in the Ecological Stations of Angatuba, Barreiro Rico, Itirapina, and Santa Bárbara, in addition to the Ilhabela State Park.
Proposals can be submitted until December 23, 2024, when the envelopes will be opened at 9 AM.
The planned control anticipates the slaughter of up to 380 animals, 200 of which will be in the Ilhabela State Park alone.
The execution will be based on a rigorous technical plan to avoid errors and negative impacts on native wildlife.
Why Are Wild Boars and Pigs a Threat?
The European wild boar (Sus scrofa), introduced into Brazil, found no natural predators in the country. This allowed for its rapid adaptation and uncontrolled reproduction.
When crossed with domestic pigs, they produce hybrid pigs, even more resilient and destructive species that consume vegetation, destroy soil, and attack other native species.
The damage goes beyond the environment. These animals are vectors of serious diseases such as foot-and-mouth disease, leptospirosis, and classical swine fever, which directly affects public health and the economy, especially the agricultural sector.
Not surprisingly, the International Union for Conservation of Nature (IUCN) classifies wild boars among the 100 worst invasive species in the world.
How Will the Control Be Implemented?
The control plan established by the Government of São Paulo includes precise measures to ensure efficiency and minimize environmental impacts. The contracted service must:
- Map the presence of wild boars and pigs in conservation areas.
- Install traps, such as fenced areas with corn bait, to capture the animals.
- Apply humane slaughter methods, aiming to avoid stress or flight of the species.
The carcasses will be disposed of in an environmentally appropriate manner, following current regulations.
Experts explain that actions like this require a rigorous scientific approach to avoid mistakes, such as confusing wild boars with native swine species, like peccaries and collared peccaries.
Experts’ Opinion
According to biologist Davi Nunes Veloso, the presence of wild boars and pigs in Brazil represents “the second biggest threat to biodiversity, surpassed only by climate change”.
In addition to ecological damage, he emphasizes the health and economic risks associated with the proliferation of these species.
“These animals are vectors of diseases and parasites that can impact wildlife, public health, and natural resources.
Control through slaughter is essential, but technical planning is necessary to avoid collateral damage to native wildlife,” says the expert.
Veloso also highlighted the importance of prior monitoring conducted by biologists, which helps correctly identify the species and ensure that measures are taken in an ethical and responsible manner.
A Necessary Effort to Protect the Environmental Future
With this initiative, the Government of São Paulo hopes to mitigate the negative impacts caused by wild boars and pigs, protecting biodiversity and ensuring a safer environment for visitors to the conservation units.
The expectation is that the plan will result in a significant reduction in the superpopulation of these invasive animals.
Those interested in participating in the bid can access more information directly on the official website of the Forest Foundation. The deadline for submitting proposals ends on December 23, 2024. The full bid is available at www.gov.br/compras.

Poderiam usar um pelotão do exército pra efetuar essa tarefa, e com isso economizar, tendo em vista a situação crítica que o país está enfrentando.
Captura e solta eles na Amazônia para tratar dos índios
Não será suficiente ou será muito difícil, talvez além desta prática começar a castrar.
