Invasive Species We Manage
Expert identification and eradication of the UK's most problematic non-native invasive plants.
Japanese Knotweed
Fallopia japonica — The UK's most destructive invasive plant. Capable of damaging foundations, drainage systems and boundary walls. A material consideration in property sales.
Treatment options →Giant Hogweed
Heracleum mantegazzianum — A serious public health hazard. Sap causes severe phytophotodermatitis resulting in burns and blistering on contact with skin.
Removal process →Himalayan Balsam
Impatiens glandulifera — Rapidly colonises riverbanks and floodplains. Each plant produces up to 800 seeds, outcompeting native flora and increasing erosion risk.
Control methods →Rhododendron
Rhododendron ponticum — Smothers native woodland understorey and harbours Phytophthora pathogens. A significant threat to protected habitats and ancient woodlands.

“Fortis Ecology were exceptional from start to finish. They identified knotweed in our garden, produced a clear management plan, and the treatment was completed efficiently. Our house sale went through without a hitch thanks to their IBG documentation.”
“We use Fortis on all our development sites across Yorkshire. Their survey turnaround is excellent, and the treatment programmes are always compliant with lender requirements. A genuinely reliable partner for any developer.”
“The rhododendron clearance across our 200-acre estate was a significant undertaking. Fortis managed the entire project with minimal disruption, and the native replanting programme has already begun to transform the woodland.”
