This paper can be published when the reviewer´s suggestions have been considered and applied, as the authors have already indicated. Please check the second reference ("Aufgenommen...) .. is this a valid reference? Please also check the german spelling of the reference of Berendt (1869); to my feeling it should read "Geologie des Kurischen Haffes und seiner Umgebung"; also, is this reference complete?

In addition, I have two minor comments which you may take up in the dicsussion:

1. Nothing is said (e.g. in the section on "Climatic factors") about the impact of rising sea level and potential impacts of potentially higher storm surges. Is it not relevant in the scope of the paper?
2. Is it possible to roughly estimate the relative impact of humans trampling over the dunes as compared to natural influences? This would be interetsing in the scope of the special issue.

Thank you for this interesting paper.

I wouldk like to encourage the authors to re-install papragraph 4 of the conclusions even though a quantification of human trampling may not possible at this point; it may be something to look for in further investigations. My last remark was not meant to delete the reference to human trampling from the conclusions.

Still I would leave this up to the authors; the paper is ready for publication also without conclusions paragraph 4.
