Amazon tribes’ forests are a vital carbon sink Updated for 2026





Scientists in the US and Latin America have once again confirmed the importance of the Amazon rainforest as a planetary resource and as a carbon sink to store carbon drawn down from the atmosphere. Sadly, they have also confirmed, once again, that it is at risk.

New research, released in time for the UN climate change conference being held in Lima, Peru, shows that 55% of the Amazon’s carbon is in the indigenous territories that are home to the regions’s 385 tribal peoples, or in formally-designated protected natural areas.

The forests are critical to the stability of the global climate, but also to the cultural identity of the forest dwellers of the region and the extraordinarily diverse ecosystems they inhabit.

Indigenous forests are carbon-rich forests

“The territories of the Amazonian indigenous peoples store almost a third of the region’s above-ground carbon on just under a third of the land area”, said Wayne Walker, an ecologist and remote sensing specialist at the Woods Hole Research Centre, US, and lead author of a paper published in the journal Carbon Management.

“This is more forest carbon than is contained in some of the most carbon-rich tropical forests, including Indonesia and the Democratic Republic of the Congo.”

The authors also found that nearly 20% of tropical forests across the Amazon are threatened by legal and illegal logging, new roads, dams and the growth of agriculture, mining and the petroleum industries, at least in part because governments had failed to either recognise or enforce the land rights of indigenous peoples.

The Amazon forest under study is a mosaic of 2,344 indigenous territories and 610 protected areas spread across nine nations. In terms of biological, cultural and linguistic diversity, these areas are exceptional.

They are also the cornerstone of conservation efforts. In this century alone, 253,000 square kilometres of Amazon rainforest – an area bigger than the UK – has been lost for a mix of reasons. And land rights of the indigenous peoples are also under attack, notably in Peru and Brazil, with more than half by area at risk.

‘Protected’ forests are more insecure than ever

A loss to the Amazon peoples would also be a loss to the planet. The Amazon rainforest is a unique resource in biodiversity and is also a carbon sink of global importance.

Every tree is a reservoir of atmospheric carbon. Every felled tree or patch of burned forest is so much carbon dioxide back in the atmosphere, to fuel global warming. The scientists warn that the carbon stored in these supposedly secure landscapes is enough to destabilise the planet’s atmosphere – or contribute to its stability.

“If all the current plans for economic development in the Amazon are actually implemented, the region would become a giant savanna, with islands of forest”, said one of the authors, Beto Ricardo, of Brazil’s SocioEnvironmental Institute (Instituto Socioambiental).

“A vast proportion of indigenous territories and protected areas are increasingly at risk, with potentially disastrous consequences, including 40% of indigenous territories, 30% of protected areas, and 24% of the area that pertains to both.”

Shot in the foot? Killing wolves, lynx, cougar increases farm predation Updated for 2026





Wolves, lions and other large carnivores rely on meat for sustenance and there are only so many wild animals to go round. Sometimes, dinner means cow or sheep.

Farmers can use guard dogs or protective fencing to deter predators and protect livestock. But lethal methods such as hunting and trapping are also used to control wild carnivore numbers.

As a livestock farmer in wolf country, it would be reasonable to assume that killing more predators would result in fewer attacks on your animals.

However, a new study by Washington State University has turned this assumption on its head by discovering the opposite: the more wolves that are killed (up to a threshold of 25% of the population), the more the remainder preyed on local sheep and cows. Why is this?

Unpicking the pack

The researchers, Robert Wielgus and Kaylie Peebles, point to the nature of the species’ social systems: wolves live in family groups containing a breeding pair (also known as the alpha pair) along with related sub-adults, juveniles and pups. The alphas are the only breeders within the group as they limit reproduction by their subordinates.

Killing one of the alphas disrupts the pack and subordinate wolves, who often outnumber the breeders, are then free to reproduce.

This could increase the number of breeding individuals in the area, thereby increasing the population of hungry wolves – maybe farmers who shoot wolves are inadvertently doing more towards conservation than they think!

Conversely, as humans are more likely to shoot youngsters than adult breeding wolves, the alphas may be temporarily be in a more favourable situation.

There would be less competition for food, fewer clashes with other wolves and less risk of the transmission of disease. Again, this could result in short-term increases in attacks on livestock.

Wolf packs also have an important educational role, as the experienced wolves pass on their knowledge. Killing them impairs this social learning. If the rest of the pack hasn’t learnt the skills necessary to take on bison or elk they may instead turn towards easier pickings on the farm.

This same behaviour has been seen in lions and cougars (although has not been documented in many other carnivore species).

When culls go wrong

It is interesting to note that this paradoxical finding is not just found in relation to wolves – lethal control of cougars (or mountain lions) also means the remainder kill more cows and sheep as younger, inexperienced cougars are more likely to attack livestock.

Coyotes also show increased litter sizes and more frequent breeding in populations that were lethally controlled. Culling programmes could have even exacerbated livestock attacks by taking out younger, less predatory coyotes.

Further, state-funded coyote removal campaigns have failed to reduce predation on sheep. Lynx, too, do not significantly reduce livestock attacks until lethal control dramatically reduces total population numbers.

It must be noted that other studies have shown that killing predators can sometimes reduce the numbers of livestock they themselves kill, but this is only temporary, until new populations of predators establish themselves.

What to do about wolves?

If we would like a world where neither livestock nor predators are killed, we are either going to have to take away all the predators or all the livestock. Clearly neither one of these options is viable so we must aim to reduce preying on farm animals to a tolerable level.

Despite proof that changes in livestock husbandry reduces predation, farmers may still not want these creatures living near them as they may feel that the carnivores have ‘won’ or taken over ‘their’ land.

As such, despite scientific evidence showing that predators don’t kill that many cattle anyway, that lethal control usually doesn’t reduce attacks, and that non-lethal methods can almost eliminate attacks, this still may not be enough to sway farmers from their anti-predator mind-sets.

We must therefore start to think outside the box. Much of this conflict between humans and wild predators is not really about protecting livestock, but instead concerns a deeper historic and cultural aversion to wolves, lions and other scary carnivores.

This won’t be fixed through simple technical solutions – and we now know it certainly won’t be fixed with a gun.
