Giving evidence to a parliamentary committee

This week, Alison Dunn who leads the Invasive Non Native Species project gave evidence at the Environmental Audit Committee’s inquiry into Invasive Species. iCASP had previously submitted written evidence to the inquiry and Alison was invited to attend the first evidence session where the Committee began to get an understanding of the issues that will shape the inquiry.

L-R: Mary Creagh MP (Chair of the EAC) with some of the witnesses from the enquiry, Professor Helen Roy (NERC Centre for Ecology and Hydrology), Dr Alison Dunn (iCASP, University of Leeds) and Professor Elizabeth Cottier-Cook (University of the Highlands and Islands and Scottish Association for Marine Science)

Some points that Alison made during her session include:

  • economically important impacts of invasive species on, for example, on the building trade and water companies
  • the importance of biosecurity to stop initial invasions, spread, or re-infestation
  • the unprecedented rate at which new species are being introduced
  • the reliance, in some cases, of biosecurity on voluntary agreements rather than legislation
  • the shift in climate that may affect whether an invasive species becomes problematic or not

Alison’s session can be seen on Parliament TV (begins at 11:36:00)

There is also a transcript of the session available

 

Dealing with freshwater invaders

Workshop to design invasive species project

Hard pressed local authorities in Yorkshire are to get some support from iCASP  in dealing with the spread of watery invaders such as Giant Hogweed, a plant that causes long-term skin burning.

Last year’s costs for removing Giant Hogweed and Japanese Knotweed from the Rivers Aire and Don was over a hundred thousand pounds. Although Yorkshire is currently largely free of Floating Pennywort, which clogs up waterways, costs of large infestations are huge. Once widespread it becomes almost impossible to eradicate this invasive species, resulting in spiralling annual costs of treatment. A new iCASP project will therefore help authorities to act now to prevent any spread.
