At other times
of the year parts of this area may be covered with the shell breccia. The
storms move it around. But the
cleared areas are useful to follow a known year class over time (or until the
next storm surge removes them) Another benefit is to follow how growth compares with other year classes on sites |
Site 1

|
|
|
The Porphyra, Acrosiphonia etc., utilize ‘cleared’ areas to settle, grow in spring— all ‘over-winter’ as microscopic plants (alternate phase) that reproduce is early spring The Porphyra is perfect
for picking to make ‘nori’ or “Indian Seaweed” |
Barnacle
Juveniles ‘everywhere’
|
|
Site 1 |

Site 2
|
|
More
diversity here |
|
Not
only the Porphyra and mature Semibalanus but anemones and limpets add to
color (below) --- note the juvenile barnacle seems to be evenly spread and
same age/ size as other rock |
See how
limpets keep its area ‘cleared’ of spat
How old are
these mature Semibalanus? Some ‘yearlings’ also evident as is another species
Site 3

Very interesting
|
|
The
triangular bolder under the “3” was so interesting will give it a full
page--- because it is a small island --- can assume its inhabitants (limpets.
snails, etc) will not move in or out – and by extension most have settled
here directly from plankton |
