UK Funds Gene Editing to Protect Threatened Wildlife

Published: 21 September 2026. The English Chronicle Desk. The English Chronicle Online.

Scientists in the UK are beginning a major programme exploring how biotechnology could help threatened wildlife cope with the rapidly changing conditions created by climate change, disease and other human pressures. The initiative includes experimental projects involving tree vaccines, gene-edited butterflies and genetically modified bacteria designed to protect amphibians from deadly infections.

The projects are being funded by the Advanced Research and Invention Agency, or Aria, a publicly funded organisation established to support high-risk research with the potential to produce significant technological or scientific advances. Under its accelerated adaptation programme, Aria has selected 14 research teams to investigate whether biotechnology can give wild species new tools to survive environmental threats.

The programme has an initial allocation of £30m for the next two years from a total planned budget of £54m. Researchers will focus on British species including ash trees, oak trees, endangered butterflies and important pollinators such as the buff-tailed bumblebee.

The research reflects a growing scientific debate over whether conventional conservation methods alone will be sufficient as ecosystems experience faster changes. Rising temperatures, drought, new diseases, agricultural chemicals and invasive pathogens can place pressure on species that may not be able to adapt naturally at the required speed.

Yannick Wurm, director of Aria’s accelerated adaptation programme and a professor of evolutionary genomics at Queen Mary University of London, said the research was intended to explore how biotechnology could responsibly help wild plants and animals respond to those challenges.

The projects are not designed to replace established conservation methods. Instead, researchers describe the technologies as additional tools that could potentially be used alongside protected habitats, restoration programmes and other traditional approaches to biodiversity protection.

One of the most closely watched projects involves the swallowtail butterfly, which is classified as an endangered species in Britain. Researchers at the University of Exeter plan to use the gene-editing technology CRISPR-Cas9 to investigate whether the butterfly can be made more resistant to insecticides commonly used in agriculture.

The objective is to explore whether genetic changes could help vulnerable populations withstand pressures that currently threaten their survival. The work will remain experimental, however, and the research programme does not involve releasing genetically modified organisms into the wild.

Another project focuses on long-lived tree species such as oak. Researchers at Rothamsted Research are investigating whether gene editing can alter aspects of the reproductive process of trees so that they can reproduce much more quickly.

Trees such as oak can take many years or even decades to mature and reproduce. Researchers hope that accelerating certain stages could allow scientists to study how trees respond to environmental pressures within a much shorter timeframe.

The potential applications include examining how trees could adapt to drought and invasive pathogens. If successful, the research could provide scientists with new information about the biological mechanisms that determine resilience in some of Britain’s most important native tree species.

Ash trees are another major focus of the programme. Ash dieback, a fungal disease, has caused widespread concern among conservationists because of its potential to reduce Britain’s ash tree population substantially.

Scientists at Cardiff University are investigating whether RNA molecules could be injected into ash trees to interfere with the fungus responsible for the disease. Project leader Sarah Christofides, a mycologist, has compared the proposed approach to vaccination because the treatment would aim to help the tree defend itself against infection.

The concept represents a different approach from conventional breeding programmes, which can require many years to develop disease-resistant tree populations. Researchers are investigating whether molecular techniques could provide a more targeted method of protecting individual trees.

Amphibian disease is another major area of research. Chytrid fungal infections have contributed to population declines among hundreds of amphibian species worldwide and have been associated with extinctions.

One project involving Cultivarium, Imperial College London and Queen Mary University of London is investigating whether bacteria naturally living on amphibian skin can be genetically modified to produce proteins capable of blocking the infection.

The researchers emphasise that their proposed approach would not directly genetically modify the amphibians. Instead, the objective would be to introduce a biological defence mechanism through microorganisms that already live on their skin.

Henry Lee, co-founder of Cultivarium, described the concept as giving amphibians a protective shield against the fungal infection rather than changing the animals themselves.

The projects nevertheless raise important scientific and ethical questions. Gene editing and synthetic biology have become increasingly prominent in conservation debates, but environmental groups and scientists have warned that altering natural systems could have consequences that are difficult to predict.

At an international conservation meeting last year, more than 90 non-governmental organisations expressed concerns about the potential risks of powerful biotechnology being used in natural environments. Supporters of synthetic biology, however, have argued that the technology could provide new ways of addressing threats that conventional conservation cannot easily solve.

The International Union for Conservation of Nature subsequently adopted a global policy on synthetic biology. The policy established criteria intended to guide decisions about the responsible use of such technologies in conservation.

Aria says those principles have influenced its own approach to ethical and social responsibility. Marie-Claire Cordonier Segger, chair of the programme’s ethical and social responsibility advisory committee, said the projects had been designed with strong safeguards.

Importantly, none of the experimental solutions will be released into the wild during the current programme, which is scheduled to continue until 2030. The research will instead take place in secure laboratory environments while scientists assess the potential benefits and risks.

That restriction is significant because any future release of genetically modified organisms into Britain’s environment would require regulatory approval. The Department for Environment, Food and Rural Affairs has strict controls governing the release of genetically modified organisms.

The research therefore remains several stages away from practical deployment. A successful laboratory experiment would not automatically mean that a treatment could be used in forests, fields, rivers or other natural environments.

Scientists also caution against assuming that biotechnology will provide a simple solution to biodiversity loss. Chris Thomas, founding director of the Leverhulme Centre for Anthropocene Biodiversity at the University of York, said some of the projects could offer useful tools for species facing serious threats, but warned that their overall impact could be limited.

According to Thomas, interventions targeting individual species could also have consequences for other organisms within the same ecosystem. Changing the resistance of one group of animals or plants could alter relationships between species, potentially producing effects that are difficult to anticipate.

The complexity of ecosystems is one reason researchers are proceeding cautiously. A biological intervention that appears beneficial in a controlled laboratory environment may behave differently when exposed to the multiple interactions found in a natural habitat.

The research also highlights the distinction between helping species adapt and addressing the underlying causes of environmental change. Scientists involved in the programme acknowledge that the most important long-term objective remains reducing the human activities responsible for climate change and biodiversity loss.

Biotechnology could potentially provide additional time or resilience for species that are already under pressure, but it cannot by itself reverse habitat destruction, rising global temperatures, pollution or the spread of invasive species.

Aria’s programme is therefore being presented as an exploration of what biotechnology might contribute rather than as a replacement for wider environmental action. Researchers hope that some of the experiments will produce sufficiently promising results to justify further development.

An additional £24m is expected to be allocated to projects that demonstrate success during the initial two years. Programme leaders hope that a small number of successful projects could eventually have a substantial effect on conservation science.

The initiative also reflects a broader shift in the relationship between biotechnology and environmental protection. Techniques originally developed for medicine and agriculture are increasingly being examined for possible applications in conservation, although their use in natural ecosystems remains controversial.

For Britain’s threatened species, the potential rewards could be significant if researchers can develop safe and effective interventions. But the risks, regulatory challenges and ecological uncertainties mean that any move from laboratory research to real-world conservation would require extensive evidence and scrutiny.

The projects now entering the research phase will therefore be closely watched by scientists, conservation organisations and policymakers. Their progress could help determine whether gene editing, RNA-based treatments and engineered microorganisms become practical additions to the conservation toolbox.

For now, the programme represents an attempt to explore what is scientifically possible while keeping experimental interventions away from the wild. Its longer-term success will depend not only on whether researchers can demonstrate biological effectiveness, but also on whether the technologies can meet demanding safety, ethical and environmental standards.
