More famous for its (diminishing, via global warming) spectacular, fully submerged, “underwater forests”, kelp can sometimes be found, alive and well, on “dry” land.
The land in question is only “dry”, briefly, at low tide.
Also, I imagine, this circumstance would only be possible where the climate is cool and humid.
The photo (copyright Doug Spencer) was taken at 10.46 am on 21 April 2015.
My beloved and I were in the Catlins – the southeastern “corner” of New Zealand’s South Island.
It is a sparsely populated, cool, wet region – a mix of farmland, wind-sculpted rainforests, and very wild shores.
The pictured kelp would have been fully immersed within another hour or three, as would have been the floor of the sea cave, just a few footsteps away.
Our feet remained dry when I took the image you will see in #12 in the intertidal series.
