Generated Summary
This news article from Beef Central discusses the ecological research suggesting that historical populations of wild herbivores were much higher than previously estimated, potentially matching current domestic herbivore biomass. The article focuses on the work of rangeland ecologist Pablo Manzano, who emphasizes the role of livestock in maintaining balanced ecosystems, challenging the negative portrayal of livestock production. The research indicates that livestock, due to their mobile nature and behavior mimicking wild herbivores, can occupy the same ecological niche, thus supporting fundamental ecological processes. The article aims to shift the narrative towards a more scientific and fact-based perspective on livestock production and its benefits to the environment.
Key Findings & Statistics
- The article references research showing that the number of wild herbivores historically was underestimated.
- The research suggests that the potential number of wild herbivores matches the current domestic herbivore biomass in the world.
- The article mentions that the often-stated statistic that livestock are responsible for 14.5 percent of “anthropogenic” emissions does not take into account the natural baseline level of wild herbivore numbers.
- The research shows evidence that many areas of the world have historically carried natural densities of wild herbivores above 10 tonnes per square kilometer.
Other Important Findings
- Dr. Manzano’s research adds more scientific evidence to support the view that the planet’s populations of wild and domesticated herbivores have not increased their rate of emissions significantly over millennia.
- Livestock grazing is similar to natural herbivory and is an important part of natural ecosystem processes.
- The article highlights the importance of mobile livestock and their role in imitating the behavior of wild herbivores to occupy the same ecological niche.
- The research indicates that if livestock are withdrawn from ecological niches, other herbivores, such as wildebeest, elephants, deer, or termites, will move in and emit methane, which is a key component of the greenhouse gas effect.
- The article references a paper titled ‘Underrated past herbivore densities could lead to misoriented sustainability policies’.
Limitations Noted in the Document

Conclusion
The article concludes by emphasizing the positive role of livestock in ecosystem maintenance, promoting a shift in perspective towards a more scientific understanding of livestock production. The research supports the idea that livestock can co-exist with the environment and that they play a role in maintaining balanced ecosystems. The key takeaway is that livestock, when managed correctly, can be part of a sustainable system. The text is clear about the role of mobile livestock and the imitation of wild herbivores, which is a great idea. Dr Manzano stressed that there are better and there are worse ways of keeping livestock – “more destructive ways, and there are more beneficial ways”, the latter based on regenerative grazing techniques that imitate the behaviour of wild animals. The research also points to the fact that moving livestock around is a trait that can be answered everywhere in the world because it makes a lot of sense. The article highlights that mobile livestock is more productive and can reduce the footprint per product compared to stationary farms where grazing stock do not move.
