The intertidal shore gives a sense of large horizons and a feeling of openness,
which spread environmental coherence information to people. However, various
substrates (e.g., mud, sand, shingles/pebbles, cobbles and rocks) of the intertidal
shore could create distinct landscape experiences. Compared to mud and sand flats,
a rocky shore is more attractive because of the jagged rocks and beautiful waves that
spray. Rich benthos and migratory birds abound, with shorebirds at the mud flats
and recreational activities popular at this area.
Emergent wetlands are in the upper coastal intertidal zone between land and
open salt water or brackish water that are often dominated by dense stands of salttolerant plants, such as grasses, herbs, or low shrubs (Adam 1993). Marshes have
scenic beauty, abundant of natural resources and accessibility could provide diverse
recreational activities, hence marshes are highly attractive natural feature to people.
As the environmental information is coherent and people perceives complexity in
the spacious marsh. The visible area of the waterbody also influences the aesthetic
assessment. The large waterbody, with birds, mammals, and fishes in the marsh,
would make the people’s preference and aesthetic value high.
Scrub-shrub wetland dominated by woody vegetation less than 6 m tall. Wetland
visual penetration may be obstructed that could not provide a sense of security and
is reasonable to interrupted people further explore in deep. As the visible area of
waterbody is broader and lies at foreground, and some conceivable and memorable
landscape feature to help people perceive legibility. Scrub-shrub wetland landscape
could encourage people to move deeper to gain more environmental information.
This kind of scrub-shrub wetland ought to get high aesthetic value and preference.
The wetland is good habitat for fish, avifauna, wildlife etc., and support a wide
range of recreational activities.
