In the earth, we can
see various plants, and one type of those plants is sea shore plants. Sea shore
plants are basically living on sea shore or shallow marine. There are very
severe places, because they are affected by a splash of seawater, a sea breeze,
strong ultraviolet rays, soils that are a sandy beach and a rocky stretch. They
adapt these places and evolved. The point of adapting to severe environment is similar
to mountain’s plants expressed in the last post. Also, they bloom beautiful
flower too. Now, alpine floras are going on ahead with protection, however, sea
shore plants are few under the protection. They are steadily declining as that
reason and more violent erosion by a rise in ocean level by global warming. Their
features are leaves thicker than inland plants, covered by hair, bloom big
flower for their height and so on.
I’ll explain them
using two plants. For example, a crinum (Crinum asiaticum) and a plant
called “hamabo” (Hibiscus hamabo) are
kinds of sea shore plants. Their way of seeds spraying is basically same as
inland plants. However, only one point is different from them. It is using an
ocean current to spray seeds. Seawater is generally harmful, but they use an
ocean current. A crinum grows on grit sea shore, and bloom white flower in
early summer. It is known since the old days, and appeared in various Japanese classical
literatures. A kind of them is distributed in mainly Southeast Asia, in the
west, India, in the east, Hawaii, in the south, Australian eastern coast, in
the north, Boso peninsula. Also, they
have some variety. Hamabo grows to a salt marsh in near a mouth of a river and
an inner bay, and blooms light yellow flower in July. Its view is similar to a
mangrove. It is distributed in from Amami
Oshima to Miura peninsula, and
South Korean Cheju Island.

The reason of declining
sea shore plants is shore protection works, reclamation, beach erosion and so
on. So, natural sea shores are decreasing. Also, they are dug because they
bloom beautiful flower.
The proposal of protection
of sea shore plants is specified as the special protection area of a national
park and a quasi-national park under severe regulation. But, now, the place
which has been the target of protection is rare.
Finally, Japan is
surrounded the sea, and the sea shore plants were familiar and common. However,
there is also an area which has disappeared now and it is precious. I would
like to retain this nature forever.
