🍄 Did you know mushrooms aid forest recovery after fires?
- Our spotlight this month is the innovative ‘Hallier Ltd. Mushrooms,’ an environmental start up which is tapping into the multi-faceted uses of fungi, to naturally restore areas of land suffering from fire damage.
- Rather impressively, Hallier Mushrooms predict to aid forests via fungal remediation and speed up the recovery timeframe to 6-12 months, as opposed to the 80 years it takes for a forest to naturally reestablish itself.
Oliver Gestrin, CEO & Founder of Hallier Ltd. (1)
- ‘’I am an environmental entrepreneur and have found my passion in utilising the fungal kingdom to address some of the world’s most pressing challenges. With a background in biosciences and business, I have spent the past 4 years building Hallier, a fungal bioremediation startup that specialises in restoring fire degraded land using native fungi. My innovative approach to restoring degraded land revolutionises wildfire recovery, as the fungi grown reintroduces elemental, microbiological, bacterial and structural properties back into the soil that were previously incinerated by the fire.’’
🍄 Three fungi wins:
De-Toxification
- Hallier Mushrooms’ use of fungi helps to reduce the amount of toxic pollutants left behind from fires in urban developments.
- Polluted soil is problematic as we can absorb a great deal of these nasties via food consumption.
- In fact, ‘approximately 78% of the average per capita calorie consumption worldwide comes from crops grown directly in soil.’ (2)
Wildfire Combattant
- We’ve all seen the spike in wild fires recently.
- This year, 856 wildfire incidents were responded to in the UK by August, with the number of wildfires being 663% more than those recorded in 2021. 1
- Not only do we need to continue educating against the spread & causation of fires, but we must also look for proactive methods to heal our land.
- Hallier Mushrooms’ land restoration methods could be just the ticket- especially as they claim to be faster and cheaper than current traditional routes.
- Animals will not return until plants have returned, so it is vital that we boost the ecosystems where possible.
Strengthen ecosystems
- A barren landscape is about as bleak as it sounds.
- Whilst forests can make remarkable recoveries from low intensity fires, high intensity fires can leave the land significantly damaged, and requiring a helping hand.
- Sometimes the soil will be so burnt that tree roots are killed off. Additionally, ash & debris takeslonger to break down and nutrify the land, leaving burnt soil running off into bodies of water, burying amphibian and fish eggs before they hatch.
- It’s worth noting that there is still natural healing in these scenarios, such as burnt-tree-loving-woodboring beetles gathering, providing food for woodpeckers.
- Not to mention the influx of nutrients returning to the soil once the dead trees have fallen and decayed (3).
- However, noting these benefits is more of a silver lining approach, as more thorough recovery is required after hotter ‘high-intensity’ fires.
- As Hallier Mushrooms states, ‘the introduction of fungi into barren landscapes lays the groundwork for revitalizing ecosystems and ensures lasting ecological resilience…The fungi essentially create rich soil that allows plant life to return quickly and prosper in quick succession.’’ (1)
So, there you have it. There’s a world of good to be done by fungi, and we’re pleased to promote such innovative, forward thinking from Mr Gestrin.
