From invasive enemy to green energy: How we fight Japanese knotweed

?? From invasive enemy to green energy: How we fight Japanese knotweed ??

Did you know that invasive plants like Japanese knotweed can be a valuable resource? ??

In our project "Promoting biodiversity by eliminating invasive plants using energy" (ITMS NFP403201DXT7), we are addressing this environmental challenge. ??

A multifunctional approach to environmental restoration ??

How we contribute to change:

• Eliminating invasive species: We eliminate harmful plants like Japanese knotweed that threaten our native ecosystems. ???? In this way, we help restore the natural balance and prevent further damage. ??
• Creating clean energy: We are exploring innovative ways to convert these plants into biofuels, contributing to a sustainable energy future. ?? In doing so, we reduce our dependence on fossil fuels and help mitigate climate change. ??????
• Supporting biodiversity: By removing invasive plants, we help native species thrive and restore balance in our environment. ???? We create healthier and more resilient ecosystems. ??

Our partners in this exciting effort:

• University of ?ilina: Investigating efficient combustion methods for energy production. ????
• V?B - Technical University of Ostrava: Investigating the potential of gasification for converting biomass into fuel. ????
• HERBATHECA: Helping us promote the project and investigating the use of invasive plants in natural products. ????

Management measures for the removal of Japanese knotweed ??

Japanese knotweed is a plant typical for its tenacity. ?? Originally from East Asia, it is considered an invasive species in our conditions. ??? It occupies various habitats, often including the banks of waterways. ?? These represent a convenient route for it to spread. Fragments of parts of roots and stems can also withstand longer journeys through waterways. ?? Once established, it grows rapidly – tens of centimeters per month and grows stronger underground. ?? It is a strong competitor for the original vegetation and its diversity. ?? Removal is quite difficult and often requires repeated management interventions. ???

Site selection and method ?? We selected a pilot section for the removal of Japanese knotweed ??? Therefore, we chose a gentle management due to the sensitivity of the area. ?? We used a combined method, digging and covering the area, so-called covering with foil. ??? Management implementation ?? We carried out the management in the autumn ?? and in 2025 we are planning to do it in the spring ?? The above-ground parts of the plant were removed in the autumn. ?? The site will be monitored regularly. ??
