Thanks, Carolyn. Well, I can happily explain why we're taking the approach that we are, although I've heard those calls for something to do with abundance on the face of the Bill. It's because, under the Environment (Wales) Act 2016, our approach that we are committed to is an ecosystem-based approach, and this focuses on the health and resilience of that overall ecosystem. Now, I've got to say, this is well founded. It's in line with the approach outlined in the global biodiversity framework. It gives that much more holistic, sustainable pathway to nature recovery in the round. So, if we go for a headline species abundance target, it would diverge from this ecosystem-based approach, which underpins all of our environmental policies, which are well established, as I say, based on the global biodiversity framework approach.
But we do recognise the importance of species abundance. We've included this as a key consideration for Welsh Ministers in setting out our targets. So, in setting the targets, Welsh Ministers, I and others have got to be satisfied that those targets contribute to halting and reversing biodiversity decline, and in particular that they contribute to increasing the abundance of native species or enhancing the resilience of ecosystems and increasing genetic diversity. So, that's our reasoning. There's a real principled point here. Whilst I understand the calls, taking that ecosystems approach is well founded, well established, and we think it's the right one.
There is another reason as well, by the way, and it's a very practical one. If we go to set a target on species abundance at this stage, it would mean doing so without undertaking the necessary scenario modeling to enable us to get to that much more specific, measurable, achievable and realistic target. We would not, if we set a target on the Bill, have done that consultation with a broad range of stakeholders across Wales as well, which could jeopardise the deliverability of a target as well.
But you mentioned as well the duration of the targets. We think, by not stating a specific requirement or time frame, we’re able to adopt a much more flexible approach, which means we can set short, medium, long-term targets. This, I’ve got to say, reflects the complexities of our environmental systems. They don’t always respond in a purely linear fashion to interventions. So, setting the right time frame for the different targets is the right approach. So, for example, setting the target to determine the condition of all our protected sites is likely to be a very short-term target. However, a habitat extent and condition target is likely to be a longer time frame. It can take decades for some habitats to be turned around and to become well established. So, that’s why we've taken the approach that we have.
