A new voice.

Yeah, so for me personally, I've got quite a bit of a different role to undertake with the management of the woodland and stuff like that.

Obviously the land's not been managed for quite some time now, so there is some trees that are going to cause issues in the future because of uncertainty and decline.

So obviously my kind of role now is to kind of bring Haig Woodlands up to a safe aspect for the community to enjoy again and hopefully over the next 20-30 years reinstate it back to its former glory.

Oh, sambuca.

Yeah, exactly.

So what you tend to find is obviously with that type of trees, they grow quite fast.

And they're not the most desirable, but they do offer... quite nice purposes within a woodland.

So if they're filtering bad stuff out and then putting it back into the water, how is that cleaning the harbor?

Right.

So there's two ways that they can either bind up or transform pollutants.

So in that process of creating pseudofeces, what they're doing is sort of taking it from the water and depositing it and burying it into the sediment.

So it, it stays there in many cases, and that's a good thing.

But for some of the pollutants, they can actually get rid of it entirely.

So in many estuaries, too much nitrogen is one of the biggest pollutants.

Why do oysters live in the ocean but not in the lake?
