A newly identified 'killer fungus' in Britain targets the invasive heath-star moss, which has been damaging local ecosystems. This fungus could help restore native habitats by controlling the spread of this aggressive plant, marking a potential natural solution to invasive species issues.
- 01The fungus, named moss die-back, was discovered by Dr. George Greiff in the Isle of Wight and is believed to specifically target heath-star moss.
- 02Heath-star moss, an invasive species in the UK, has proliferated since its arrival in the 1940s, threatening native moss populations and ecosystems.
- 03The fungus may represent a rare case of the British environment naturally combating an invasive species, potentially aiding in habitat restoration.
- 04Dr. Greiff's research indicates that the moss die-back fungus primarily affects heath-star moss and one other moss type, suggesting limited impact on broader biodiversity.
- 05The discovery of this fungus provides a natural biological control method, reducing the need for resource-intensive human intervention against invasive species.

A new species of fungus, termed moss die-back, has been discovered in Britain, providing a potential solution to combat the invasive heath-star moss, which has been detrimental to local ecosystems. This fungus, identified by Dr. George Greiff, infects and destroys the heath-star moss, which has proliferated across the UK since its introduction in the 1940s. The heath-star moss has been known to outcompete native mosses, leading to significant ecological damage. The fungus exhibits a unique ability to specifically target this invasive plant, offering a natural method for controlling its spread. Dr. Greiff's observations in areas like Bannau Brycheiniog national park reveal the fungus's effectiveness, allowing native plant species to thrive in previously moss-dominated areas. While the fungus is closely related to the ash die-back fungus, initial studies suggest it poses little threat to other plant species. This discovery is seen as a rare instance of the British environment fighting back against invasive species, providing hope for the restoration of native habitats.
