That means managed retreat - leaving nature to take its course and the inevitable consequences of erosion.
It is one of those days which is perfect beach-walking weather as long as you are wrapped up warmly.
Howard and Sylvia Oliver come to visit Studland often from their home along the coast in Swanage.
They agree the beach should be left as it is.
Pointing towards Brownsea Island, Howard admired the coast: "Look at that - it's the open stretch of water and sand, it's just superb.
"I'd certainly be sad if we lost a lot of it."
He didn't want to see groynes - wooden or concrete barriers - put up in the sea to slow down the erosion.
"I think it would be a real shame, " he says.
The National Trust has experimented with gabions, metal grilles filled with rocks, which are supposed to soak up the force of the waves.
But they were washed away.
Visitors to Studland will see far less as the years go by
Some visitors do believe in a more solid effort.
Clive Arnold was over with his family on the chain ferry for the afternoon.
"I think some drastic action needs to be taken pretty soon. I think if you left nature to take its course the beach would be eroded so fast.
"At least if you put groynes in there would be something left for the people to enjoy."
It is a view recognised by Emma but she believes it will only delay the inevitable and, anyway, the National Trust is well aware of the sacrifices it will have to make as the erosion continues.
Its own visitor centre, car park and restaurant will be lost.
To relocate would cost an estimated £3.6m and there is nowhere for it to go since most of this peninsula is closely protected as a designated Site of Specific Scientific Interest.
Ironically the National Trust is hampered by the very policies it supports.
No-one can tell how quickly the erosion will take effect. As the sand moves, other areas are enlarged.
"At the moment we're turning back the clock.
"We're where we were in Tudor times, the sand is moving around and the water has come in," but even with expert advice, Emma says the future is unknown and that is what makes her job at Studland unique.
"I'd love to know what it would look like in 100 years. It is ever changing and unpredictable".
