1/6 ROCKY MARSHES
The Patagonian #RockySaltMarshes develop on top of wave-cut platforms of sedimentary rock highly exposed to wave action and commonly dominated by a dwarf ecotype of the austral cordgrass Spartina densiflora with a 40% cover. I introduced the RSM concept In 2005.

Spartina plants often show naked roots/rhizomes in a natural hydroponic-like system with little to no accumulation of fine sediments. A fact that a famous Editor didn& #39;t want to believe no matter what results I had. No hard feelings, Just to mark how new this was to science

Don’t get me wrong. Spartina is so deeply anchored in the substrate that a strong person may find difficult to pull a mat out without a sharped heavy shovel. Besides the superficial mat or roots, some rhizomes developed deep in the rocks (green) forming lots of roots

Some RSM are dominated by small Spartina alterniflora plants, and also Sarcocornia species may be abundant. Unvegetated areas are always dominated by native mussels Perumytilus purpuratus and Brachidontes rodriguezii and the exotic #invasive #Balanus glandula

Bare rock is virtually nil in these mashes and the habitat can vary from high to low in complexity:
HIGH: Spartina + Multilayer Mussel Bed
MED: Multilayer Mussel Bed
LOW: Monolayer mussel bed and/or barnacles.

Our experiments in RSM with real plants and fake Spartina-like and Sarcocornia-like inert mimics showed that plants shape the associated benthic community just by adding a complex 3D complexity. They even favor the survival of invasive invert spp.

Some RSM literature and an old video I made for a class (note: the Spartina mat was already pulled out when I filmed it here).
