The project investigates a lesser-known attribute of mycelium, which is its high fire resistance, with the aim of preserving biodiversity in forests vulnerable to wildfires. Instead of traditional 'firebreaks', which involve creating gaps in forest vegetation, mycelium blocks can serve as an initial defense against fire damage. These blocks create a non-toxic barrier that impedes the spread of fire, resembling natural tree barks with their rough surfaces, which offer protection from heat and provide habitats for wildlife. By mimicking the rugose nature of tree barks, the mycelium blocks vary in surface roughness, incorporating peaks and valleys to enhance their effectiveness in creating habitats for biodiversity in forests.
