    B1.5 Coastal dune heaths

    Why should this unit be divided according to dominant species as soon as it is proposed to separate the other level 3-habitats of B1 (for instance B1.4, B1.6) according to biogeographical regions only? Wouldn’t it be enough to change only its title in order to highlight the biogeographical region concerned (Boreal and Atlantic)? So we would keep the same parameter for all the divisions of B1.

    If the habitat B1.5a ("Atlantic and Baltic coastal Empetrum heaths") is retained, perhaps it would be useful to quote Erica tetralix in its title as it can be a dominant species even able to replace Empetrum.

    B2.5 Shingle and gravel beaches with scrub

    In France, this habitat exists on the Atlantic coast. It can be represented for instance by Ligustrum vulgare-Hippophae rhamnoides or Ulex europaeus thickets. The proposal to merge this type of habitat into the others habitats of B2 is problematic as soon as these other habitats are not composed of scrubs but of herbaceous or woodland vegetation? The problem will be the same with the proposal to “merge F6.5 Macaronesian garrigues with other habitat types on shingle and gravel beaches”.

    agree with Vincent - B1.5 splits into the Empetrum and Calluna types at Level 4

    I cannot see justification for merging scrub on coastal shingle with other vegetattion on shingle. Indeed there is a case for splitting this into dwarf-shrub heaths on shingle and taller scrub on shingle (Prunus, Ulex and others). These are widespread and significant habitats in Scotland and elsewhere in UK.

    B1.1 Sand beach driftline & B1.2 Sand beaches above the driftline

    Driftline habitats weren't among revised habitats, but we would have a comment for their division and descriptions. The concept of driftline is a quite unclear, at least in the northern Baltic Sea, where there is no tide. The names of the classes (”above” or ”driftline”) seem to refer to an abstract border that marks the level where material would theoretically accumulate, if there were something that waves could bring to the beach. So, could  you, please, clarify in the descriptions, whether a beach that normally does not have any piles of plant material, should be divided into driftline and above driftline habitats or does it belong entirely to the ”above driftline” habitat?

     

    B1.5a Atlantic and Baltic coastal Empetrum heaths & B1.5b Atlantic coastal Calluna and Ulex heaths 

    From the Fennoscandian point of view this division and the new descriptions are better than the old ones.
