NatureMetrics has pioneered a method to catalog species by analyzing DNA traces left in river water, offering a faster, cost-effective, and standardized way to monitor biodiversity globally.
- DNA shed by animals in rivers provides a detailed species snapshot.
- Sampling requires no expertise and disturbs no habitat.
- Data supports conservation, industry, and global biodiversity tracking.
What happened
Measuring wildlife populations has long been challenging due to inconsistent data from traditional field surveys, where trained ecologists often return with conflicting species lists after visiting the same site. NatureMetrics addressed this by harnessing environmental DNA (eDNA), a collective term for DNA traces organisms leave behind in water through skin cells, saliva, and other biological materials. By filtering a liter of river water, their technology can detect and map back to various species such as fish, amphibians, mammals, and insects that recently occupied the area.
This method requires no specialized training—kits have been successfully used by people as young as five—and does not disturb the ecosystem. Samples are sent to a lab where DNA sequencing identifies every species present, enabling highly accurate, rich, and standardized data sets. Since its launch, NatureMetrics has processed samples from 116 countries, surveying 10 percent of Earth's surface and collaborating with over 600 organizations.
Why it feels good
Freshwater species have seen dramatic declines, with populations dropping 84 percent since 1970. Nature’s health is closely tied to human wellbeing and economies, as over half of global GDP depends on natural resources. This new eDNA technology provides a vital tool for monitoring biodiversity loss and restoration progress at unprecedented global scale and precision, helping to safeguard nature and the services it provides.
Moreover, it allows diverse stakeholders—from conservation groups like WWF to industries involved in mining, energy, and agriculture—to make informed decisions that protect ecosystems. The method’s recognition as an Earthshot Prize finalist strengthens its credibility and encourages corporations to acknowledge nature’s value in their financial and operational planning, putting biodiversity considerations directly into boardroom discussions.
What to enjoy or watch next
The future of environmental monitoring is bright as eDNA gains traction among businesses eager to integrate biodiversity into their sustainability strategies. Expect more widespread adoption of this technology as companies move to include nature in their accounting practices, helping to quantify environmental impact and improve ecosystem stewardship.
Additionally, ongoing advances in DNA sequencing and data mapping promise to expand the scope and ease of biodiversity assessments. Following NatureMetrics’ journey and the broader acceptance of eDNA can provide valuable insights into how technology is empowering global conservation and inspiring new ways for humanity to coexist harmoniously with the natural world.
