Floating world

We have had this floating planter in our pond for years and years.
For quite a while it had some sort of flowering marsh plant in it, but that died off and it has just floated around with the odd weed.
Noticed today that the next stage of colonisation involves a cupressus, a sycamore and some celandine.
It has also anchored itself to the side.
Time for a bit of intervention I think.
