Turtle populations decline or disappear, what are the broader environmental consequences we're looking at?

Yeah, so one of the big things that they do is they eat a lot of dead stuff.

Turtles, every species of turtles that we work on in the Murray especially are what we call generalists.

They eat a lot of different things.

So the short-necked turtles eat pretty much anything.

They'll eat vegetation, they'll eat animals, they'll eat carrion.

Uh, the long-necked and the broad-shelled turtles are more carnivorous, but they're still pretty generalist, so they still eat a lot of varieties of different things.

Is there a stable environment for them then? Is there a way that we can build an environment that makes things easy for them?
