A newly discovered fungus that kills an invasive moss is raising hopes that some native British habitats could be restored, scientists have said.
The fungus, which has been described as a 'killer fungus', specifically targets a type of moss that has decimated native plant communities in several habitats across the UK. Exact figures on the extent of the damage are not yet available, but researchers believe the invasive moss has choked out many native species.
“A newly discovered killer fungus could help restore British habitats decimated by invasive moss, offering a natural control method without chemicals.”
The discovery offers a potential natural solution to a problem that has frustrated conservationists for years. Instead of using chemicals or manual removal, the fungus could provide a biological control method, allowing native flora to recover.
In England, affected areas include heathlands and bogs where the invasive moss has spread aggressively. Similar problems have been reported in parts of Wales, Scotland, and Northern Ireland, though the specific impact varies by region. The fungus appears to be equally effective across different climates within the UK.
Researchers emphasised that the fungus is not a threat to native mosses or other plants, as it has evolved to attack only the invasive species. 'This is a very promising development,' said one expert quoted in the report. 'We have been looking for a natural enemy of this moss for years, and now we may have found one.'
Further studies are planned to ensure the fungus can be safely introduced into the wild without unintended consequences. Field trials are expected within the next two years, and if successful, the fungus could be deployed across multiple sites.
For UK readers, this could mean the restoration of beloved natural landscapes that have been overtaken by invasive moss. Hikers and nature enthusiasts may see heathlands and bogs return to their former state, supporting a richer variety of plants and wildlife. Conservation groups are hopeful that this natural approach will be cost-effective and environmentally friendly.
