The question
To ask the Scottish Government, in the event that no further significant action is taken, what it anticipates any increase in the coverage of giant hogweed will be by (a) 2030 and (b) 2040.
The answer
Recent modelling work predicts that the climate envelope of suitability for giant hogweed in north-west Europe will shift north in the next three decades (Anibaba et al., 2022). The model suggests that Scotland will remain climatically suitable for giant hogweed until at least 2050. Parts of the west coast may become less suitable due to milder winters by 2100.
In 2012, a team based at Biomathematics and Statistics Scotland (BIOSS) modelled the potential for further invasion by giant hogweed in Great Britain (Catterall et al. in 2012). The model predicts that between 2020 and 2030 giant hogweed will be found in a further twenty-seven 10km squares where it has not been recorded previously. The paper does not include predictions for 2040 but the results of the modelling suggests that giant hogweed will continue to colonise further areas beyond 2030.
However, a significant amount of work is being carried out across Scotland to control invasive non-native plants including giant hogweed. The Scottish Invasive Species Initiative is a 5-year partnership project tackling invasive non-native species including giant hogweed alongside rivers and water courses in an area of 29,500 square kilometres within northern Scotland
- over a third of Scotland. The project is funded by the Heritage Lottery Fund, NatureScot and through in-kind support from project partners and volunteers. The total project value is approximately £3.24M.
The Tweed Invasives project was set up by the Tweed Forum to tackle invasive plants, including giant hogweed, along 300 miles of the River Tweed and its tributaries. The project is funded jointly through the European Agricultural Fund for Rural Development and the Scottish Government’s Biodiversity Challenge Fund. Between 2019 and 2021, the Biodiversity Challenge Fund has provided around £300,000 to support catchment-based control of invasive plants on the rivers Tweed and Endrick.
In September 2021, at CoP26, Scottish Ministers announced that the Nature Restoration Fund would provide £65 million for projects that benefit nature to be funded through this Parliamentary session. Habitat and species restoration, and eradication of invasive non-native species are among the types of projects that can apply for grants funding, including for projects lasting up to three years.
