I thank Joyce Watson very much for raising two extremely important issues this afternoon. The first issue related to agricultural pollution incidents and the incident that Joyce described is subject to ongoing investigation. But, as we set out in our water strategy, agriculture is a major cause of water pollution, which is why the Minister is so keen to work with farming unions to develop sustainable solutions, whether through the better targeting of our financial assistance or by improved training through Farming Connect.

The Minister issued a statement on agricultural pollution last December, and in that she set out the requirement for regulations to be introduced, and they will come into force in 2020. And that is the right thing to do, not only for the environment, but also to ensure that Wales maintains its excellent international reputation in terms of farming. The number of incidents has increased over the last year, so that's obviously of great concern, and the Minister will work closely with the sector in terms of developing the regulatory reform and knowledge transfer, which I think are both necessary to address this particular issue. 

I know that you've raised your concerns regarding netting in correspondence to the Minister and that she's prepared a response to you on that. We have received some reports of netting. We're not yet aware of how widespread it is, but clearly any incident is of real concern to us. Joyce Watson referred to the petition, which has just opened at the National Assembly for Wales. There's also one in Parliament with 330,000 signatures. So, I think that this is a real concern to members of the public. There might be occasions when the netting of trees would be legitimate, but that is only when it is absolutely genuinely needed to protect birds and prevent them from nesting during developments so that they don't come to harm, and that kind of circumstance would be extremely rare indeed. So, on the whole, I think that our policy certainly is moving away from mitigating harm and damage to integrating biodiversity and ecosystem resilience into the very earliest stages of due development control.
