River Ecosystems

Viscount Ridley Excerpts

Wednesday 27th February 2019 Lords Chamber

[Lord Gardiner of Kimble]

The noble Lord raises the point that we are bringing back environmental law. We the British have been some of the pioneers of that within the European context and we are very pleased to have that environmental enhancement, wherever it comes from.

[Viscount Ridley (Con)]

My Lords, the Northumberland Rivers Trust, of which I was at the time a trustee, tried to solve the problem of poor water quality in the River Blyth in spring and summer, when it went turbid and cloudy and there was a detrimental impact on the ecosystem. After doing a lot of work on farms, it was concluded that the main problem was the invasive alien signal crayfish. Does my noble friend agree that invasive alien species are a form of pollution that can be even more damaging than other forms?

[Lord Gardiner of Kimble]

My Lords, even invasive species usually need good-quality water in which to, unfortunately, flourish. I am very strong on this—invasive species have caused great harm to our natural ecosystems, and we need to manage those species properly, because otherwise we will lose our natural ecosystems.
