In the Peruvian Amazon, the roar of bulldozers is intruding on the ancestral lands of one of the world’s last isolated tribes. The Mashco Piro, long shielded by dense rainforest, now face encroachment from a logging company with a history of violent clashes. At stake is not only their survival, but the credibility of a global sustainability watchdog meant to protect them.
The Peruvian Amazon is alive with the screech of macaws and the barking calls of yellow-tailed monkeys moving through the canopy. But for the Indigenous communities who live there, this chorus is increasingly interrupted by the rumble of heavy machinery clearing tracks for logging.
On August 18, neighbours of the Mashco Piro – thought to be the world’s largest group of Indigenous people living in voluntary isolation (IPVI) – reported the sound of bulldozers crossing a bridge built by the logging company Madera Canales Tahuamanu (MCT). The bridge spans the Tahuamanu River, a key transport route in this part of the Amazon, and would allow logging equipment to penetrate deeper into the forest.
‘It is very worrying; they are in danger. Something bad could happen again’, said Enrique Añez, president of the nearby Yine community, in a statement to Survival International. Days earlier, the Mashco Piro had approached the Yine – a move which Survival and local Indigenous organisations consider a sign of their distress.
For IPVI who have no immunity to common diseases, any contact with outsiders can lead to the extinction of the entire group.
Who are the Mashco Piro?
This is not the first time the Mashco Piro have faced threats from logging activities inside their territories. In 2002, the Peruvian government designated parts of their ancestral lands as an Indigenous reserve; however, two-thirds were excluded, much of which was sold off to logging companies, with one of the largest concessions going to MCT.
Despite holding a Forest Stewardship Council (FSC) sustainability certification, MCT’s operations have been marked by violence. In 2022, clashes with the Mashco Piro left one worker dead and another injured, after which the FSC declared the company inactive. When more fatalities occurred in 2024, international media pressure led the FSC to suspend the logging company’s trading certification – a move Survival and Peruvian Indigenous organizations say came far too late.
Now, the latest reports suggest logging has resumed, prompting the campaigners to warn of a trajectory with deadly consequences, and to call on the FSC to finally take decisive action.
Indigenous rights hang in the balance
In July, the FSC released a report on the Mashco Piro acknowledging that MCT’s concession overlaps with their territory and stressing the case’s ‘precedent-setting’ importance for the rights of IPVI globally.
The FSC is ‘at least admitting its system has been insufficient to protect the Mashco Piro,’ said Teresa Mayo, campaign lead on the Mashco Piro for Survival, though she added that their conclusions remain vague at best.
The report warns that any activity in the Mashco Piro territory risks ‘decimating their population’, yet stops short of recommending the termination of the certification.
Speaking to the Latin America Bureau (LAB), Marc Jessel, Chief Systems Integrity Officer at the FSC, said the report marks the first step toward reforming guidelines for interacting with Indigenous peoples in cases where Free, Prior and Informed Consent (FPIC) is impossible, as with isolated tribes. ‘There has been a weakness in how we frame things normatively, and the idea is to plug that gap,’ he said. The FSC plans to publish an ‘advice note’ on such situations by 14 November, while MCT’s certification is up for reassessment in December.
But NGOs warn that bureaucratic processes could cost lives and fear MCT’s certification may be renewed. Angus MacInnes of the UK-based NGO Forest Peoples Programme (FPP), who has worked extensively with the FSC system and with isolated tribes, said: ‘Given the long-standing awareness of the risks, and the fact that suspension has not eliminated them, there is a strong case for bypassing renewal altogether.’ Anything less, he added, ‘sends a signal that even the gravest rights violations can be managed through procedural delay.’
No-go zones, a false solution?
In cases like that of the Mashco Piro, where logging concessions overlap with Indigenous land, the FSC’s solution is to keep certification intact whilst designating ‘no-go zones.’ ‘We see the certification as a mechanism that enables us to exercise leverage. That is why we exist,’ explained Jessel from the FSC.
If certification were renewed, the FSC says it would be conditional on setting aside areas overlapping Mashco Piro territory as off-limits to any activity. Jessel added that withdrawing altogether would not necessarily improve conditions for isolated peoples, pointing to the many non-FSC-certified companies in the region that, he argued, could pose even greater risks.
But NGOs and Indigenous organizations caution that the proposal is unworkable and potentially deadly, since it still creates a risk of contact. ‘The concept of “partial overlap” is legally irrelevant if any part of the concession contains or is used by IPVI’, FPP’s MacInnes explained. Survival called the idea ‘both an assault on Indigenous peoples and dangerously naïve.’
Beyond the ethical concerns, critics stress that Peru’s weak chain of custody – the system that tracks a product from its origin through every stage of processing, transformation, and distribution to ensure its source is verified and, in this case, legal and responsibly managed –, as well as poor government oversight, make logging nearly impossible to monitor. They warn this could allow illegal timber to slip into FSC-certified supply chains – or worse, lead to further fatal clashes.
When questioned on these concerns, the FSC insisted that hidden cameras and GIS technologies can provide sufficient surveillance.
Yet FPP highlights other cases where ‘no-go zones’ have failed to safeguard Indigenous rights. For instance, in Mahakam Ulu, Indonesia, the FSC revoked Kemakmuran Berkah Timber’s (KBT) certification after the company violated the rights of the Long Isun Indigenous community. FPP’s MacInnes, who oversaw the case, explained that KBT agreed to halt operations in the section of its concession that overlapped with Long Isun’s land. However, this did not stop the company from continuing harmful practices, such as logging in neighbouring communities and infringing on their rights.
They also highlight what they see as a deeper structural flaw: the FSC itself does not carry out certification. Instead, it accredits certifying bodies (CBs) that decide whether a logging company is complying with FSC standards. These auditors are paid directly by the companies they inspect, creating a financial incentive to downplay risks.
In MCT’s case, MacInnes of the FPP argues that Preferred by Nature, the CB responsible for MCT’s concession, ‘had full knowledge’ of the dangers to the Mashco Piro, yet ‘failed to act decisively.’ The CB was contacted for comment but did not respond.
Indigenous leaders further stress how certification can be used to mask abuses. ‘The wood they harvest says “certified forest” but it should say “sacrificed people”’, Yine leader Añez stated to Survival.
Indigenous-led guards are the best monitors, says NGO
FPP, which works to centre Indigenous forms of forestry governance, says that Indigenous guards systems can be effective monitors of illegal activities. These methods which have emerged across the Amazon in Ecuador, Colombia, and Peru see Indigenous people monitoring their own territories in the absence of state protection. In the far north of Peru, Indigenous Wampis guards patrol the Santiago River armed only with wooden spears, yet effectively deter miners bringing in illegal machinery – though they lack the firepower to confront the criminal gangs driving the gold rush. Known as Charip – ‘lightning’ in Wampis – these warriors gained recognition from the Peruvian state after detaining three police officers who had been operating as armed enforcers for illegal gold miners.
MacInnes expressed to LAB his belief that the FSC should ‘back Indigenous-led surveillance and early-warning systems, drawing on examples where local governance institutions have successfully implemented precautionary measures and conservation programmes’. He pointed to working examples such as the Cañamomo Lomaprieta Indigenous Reserve in Colombia, where the governing council leads community-based territorial monitoring and restoration, including the planting of around 61,000 trees. Other Indigenous guards across the Amazon who blend ancestral knowledge with modern technologies to defend their territories from extractive industries could also serve as reference points, he added.
Such proposals introduce pressing questions for the FSC about the suitability and efficacy of the methods it currently uses to ensure wood is logged ethically and sustainably.
What’s at stake
The FSC’s decision on whether to terminate MCT’s certification will set a global precedent for applying FPIC in cases involving isolated tribes. Indigenous organizations and NGOs urge the forestry certifier to act decisively, arguing that the Mashco Piro case offers a rare opportunity to advance Indigenous-led forest governance, while a weak response would undermine the FSC’s credibility.
But the FSC maintains that, as a voluntary certification scheme, it cannot take responsibility for harm and can only work to encourage better company behaviour.
These debates raise broader questions about the power – and limits – of sustainability certification in protecting Indigenous rights amid the mounting threats of illegal logging in the Amazon.
With the resumption of logging activity and the world’s forest watchdog yet to make a final decision, the stakes could not be higher.
