Habitat classifications use the
associations between reoccurring groups of organisms, substrate type
and wave exposure to describe variations in the communities found on the
shore.
In
the posts that follow are images of habitats based on the JNCC habitat
classification hierarchy with a brief description of each, with emphasis
on rocky shores.
One of the major subdivisions of the habitat classification hierarchy the characterization of rocky habitats based on the level of wave exposure experienced by the rock, which ranges from high to low energy.
The images below show examples of high energy littoral rock, moderate energy littoral rock and low energy littoral rock:

The images below show examples of high energy littoral rock, moderate energy littoral rock and low energy littoral rock:
High energy littoral rock (LR.HLR) |
Moderate energy littoral rock (LR.MLR) |
Low energy littoral rock (LR.LLR) |
There
is an additional divide to capture specific physical
or temporal features within rocky communities that can occur across wave
exposures. These habitats come under the habitat Features of littoral
rock (LR.FLR). Such features include rockpools, caves and ephemeral
seaweeds.
Rockpool habitats would come under the broad habitat features of littoral rock (LR.FLR) |
