As the world faces an unprecedented biodiversity crisis, innovative solutions are urgently needed to safeguard our planet’s natural heritage. Genomics emerges as a key player in this arena, offering groundbreaking insights into the biology, ecology, and evolution of various species. This post delves into the role of genomics in conservation, spotlighting the latest advancements and practical applications.
To fully appreciate the transformative potential of genomics in conservation, it is essential to understand some of the key techniques and methodologies that underpin this field. Among the most significant are genomic barcoding and environmental DNA (eDNA), both of which are reshaping our approach to studying and protecting biodiversity.
What is Genomic Barcoding?
DNA barcoding identifies species by analyzing a short, standardized region of DNA. This method involves collecting tissue samples, extracting DNA, sequencing it, and then comparing the sequence to a database like the Barcode of Life Data System (BOLD) to pinpoint the species. This powerful technique is employed across various domains including species identification, biodiversity analysis, food safety, and conservation efforts.
What is eDNA?
Environmental DNA (eDNA), also referred to as metabarcoding, captures genetic material from environmental samples (such as soil, water, or air) without direct interaction with the organisms. In contrast to barcoding, this method does not focus on one specific organism, but instead aims to determine species composition within a sample. This method allows for the detection of species from minute genetic traces left in their environments, offering a less invasive and highly effective tool for assessing biodiversity and ecosystem health. This makes it a powerful tool for monitoring biodiversity, tracking invasive species, and assessing ecosystem health with minimal disturbance to the environment.

Species Identification and Monitoring
Genomic tools enable precise identification of species and subspecies, which is critical for monitoring biodiversity and enforcing anti-poaching laws.
NatureMetrics
Harnessing eDNA for Environmental Insights
NatureMetrics is at the forefront of using genomic technologies to revolutionize biodiversity monitoring and environmental management. Specializing in environmental DNA (eDNA) analysis, NatureMetrics provides innovative solutions for tracking species presence and assessing ecosystem health. By collecting and analyzing DNA from environmental samples such as water, soil, and sediments, they offer a non-invasive and highly accurate method for biodiversity assessment. Some of NatureMetrics' success stories are detailed below.
Scottish Government Collaboration
In collaboration with the Scottish Government, NatureMetrics used eDNA technology to monitor the biodiversity of freshwater systems across Scotland. This initiative aimed to establish a comprehensive baseline of aquatic biodiversity to support environmental management and policy decisions. By sampling water from various freshwater bodies and analyzing the eDNA, they could detect the presence of a wide range of species, including those that are rare or difficult to observe directly. For example, the eDNA analysis identified species such as the critically endangered European eel (Anguilla anguilla), and the iconic threatened harbor porpoise (Phocoena phocoena). The success of this project has helped shape policies and conservation efforts in Scotland, demonstrating the power of eDNA in large-scale biodiversity monitoring.

Okala Unlocks Green Investment Using eDNA
In another innovative project, NatureMetrics partnered with Okala to leverage eDNA for unlocking green investment opportunities. Okala is an environmental consultancy firm, which aimed to attract investment for conservation projects by providing robust and credible biodiversity data. The companies main focus is central Africa and they have a pilot site in Gabon, which started in 2020 with 270,000ha of rainforest. Through the use of eDNA analysis, they were able to offer investors detailed insights into the biodiversity of specific areas, ensuring that their investments supported genuine and impactful conservation efforts. In total, more than 1,300 species, including 11 IUCN Red Listed Species (including forest elephants and giant pangolins) and 25 species potentially new to science were detected during the project.
Overall, by establishing a clear baseline and ongoing monitoring framework, eDNA provided transparency and accountability, critical for securing and maintaining investor confidence. This project showcased how cutting-edge genomic technologies could enhance environmental transparency and drive sustainable investment in conservation projects.
Genetic Diversity Assessment
Maintaining genetic diversity is crucial for the survival and adaptability of species. Genomics provides a detailed picture of genetic variation within and between populations, which is essential for identifying populations at risk and making informed decisions about breeding and relocation efforts.
Wildlife Conservation Society (WCS)
Safeguarding Bison through Genomic Research
The Wildlife Conservation Society (WCS) is dedicated to preserving wildlife and wild places across the globe. By employing cutting-edge technologies, WCS aims to enhance conservation efforts, ensuring the genetic health and long-term survival of diverse species. Their work includes various initiatives that leverage genomics to address critical conservation challenges, from protecting endangered species to managing genetic diversity within populations.
Genomic Study of Bison Diversity
One notable example of WCS's application of genomics is their large-scale study on North American bison. This research aimed to assess and safeguard the genetic diversity of wild bison herds, crucial for their long-term conservation. By sampling DNA from various herds across North America, WCS uncovered significant genetic diversity concerns, including inbreeding risks and genetic bottlenecks that threaten the species' survival. These findings underscore the urgent need for conservation actions to mitigate genetic risks, maintain diversity, and enhance population resilience. The full report can be accessed here.
Understanding Adaptation and Resilience
Genomics plays a crucial role in understanding how species adapt to changing environments and build resilience against threats such as climate change, habitat loss, and disease. By examining genetic variations and adaptive traits, researchers can identify the mechanisms that enable species to survive and thrive under diverse conditions. Below are is one notable example where genomics has been employed to study and enhance adaptation and resilience in wildlife populations.
Government of Canada
Studying Adaptation and Resilience to Climate Change
Canada’s Genomic Adaptation and Resilience to Climate Change (GenARCC) project exemplifies the application of genomics in conservation to address climate change challenges. Led by a collaboration of Canadian research institutions, GenARCC uses genomic tools to study and enhance species' resilience to environmental changes.
A few of the key focuses include assessing the genomic vulnerability of caribou, including identifying emerging pathogens, to predict whether populations have the capacity to adapt to climate change. The project also assesses the capacity of boreal tree species, their microbiomes, and their pests to adapt to climate change, which informs climate-resilient forest management activities, including assisted migration and reforestation. Additionally, the project evaluates the genomic vulnerability of northern and northwards-moving wildlife species to climate change, including factors that influence disease dynamics of existing and emerging pathogens, with a focus on species harvested by Indigenous communities.
