They live in rivers, so they can move upstream, they can move downstream.
So
It's very hard to estimate numbers in one river, let alone their entire range, which is, as I said, is, you know, northern Queensland down to Tasmania.
So we know for some localized areas that there are declines happening and we know, like, they're threatening processes.
So...
If we think about in Australia, we have a lot of big dams which overlap the distribution of the platypus.
So we have issues with water regulation.
You know, platypuses, they're dependent on both the river and also the health of the riparian vegetation.
So the vegetation alongside rivers where we have a lot of clearing and
We have a lot of sedimentation, urbanization, pollution, predators.
And the big one is climate change, really, here in Australia.
So they've been around for millions of years.
They're well adapted to our environment.
They know floods, they know fires, they know droughts.
But the problem that we're seeing is the increased frequency and intensity of these events.
And they're kind of occurring...
back to back so you know in the last 10 years we've had some of the worst flooding on records we've had the worst bushfires on records and we've had some of the worst droughts so for an animal that depends on waterways that is a huge problem and so we suspect that populations are declining they're not currently listed as a threatened species which we're trying to get them listed at because we want them to have the maximum amount of protection we don't want to end up in a situation where
they become too far gone and they're listed as a threatened species.
And, you know, by the time we try to enact any conservation management, you know, they're kind of already beyond that point of no return.
