Environmental Improvement Plan 2023

Lord Trees Excerpts

Monday 6th February 2023 Lords Chamber

[Lord Benyon (Con)]

The noble Lord raises an important point. First, it surprised a number of people that one of our targets on water quality was based around the release of toxic substances from old mine workings, but it had emerged that this is a serious problem in certain parts of the country. That is why we have a very clear target to deal with that difficult issue. I think the point the noble Lord is really raising is around port developments, possibly in the Tees area. This is a matter of great concern to us, and to everyone, because of the horrendous deaths of crustaceans on 70 miles of coastline in the north-east. As he knows, we have carried out a panel inquiry under the auspices of the chief scientific adviser at Defra, Professor Gideon Henderson, so some of the best people in the business are looking into this. It is of great regret that we have yet to pin down what caused this tragic occurrence in the ecosystem of the North Sea, but I assure him that all dredgings in that area—and indeed anywhere else—will be subject to the most rigorous inspections. We will do all we can to get to the bottom of what caused this, but the information we have is that there was not enough possibility of pyridine being released into the sea to cause deaths on this scale. We remain determined to find out what happened.

[Lord Trees (CB)]

My Lords, the Government have ambitious and admirable targets for tree planting, but what assessment has Defra made of our nursery capacity here in the UK to provide all the native saplings we will need in order to avoid importing trees, with the risk of importing tree pathogens? Past experience has shown us that this can negate all the benefits of reforestation.

[Lord Benyon (Con)]

The noble Lord is entirely right. We are doing all we can to increase the capacity of our native tree nursery sector to produce what is needed for the very ambitious plans we have for tree planting. Our reliance on imports in past decades has contributed to some of the diseases we have seen come our way, with tragic consequences. We are doing a lot through a variety of different grant schemes, but we are also showing that the market is there for the sector to expand. Our requirement that trees planted on public estates through public procurement have to be from Plant Healthy-registered nurseries only will encourage a great many more nurseries to go into that scheme. That will ensure that only those plants we can guarantee the health of will be sold in those public procurement contracts.
