Photo 15.4a, b Natural shoreline, with well defined by vegetation could get high
aesthetic value (Photo 15.4a); conversely, aesthetic value is lower (Photo 15.4b).
That is related to accessibility of coastal wetland, due to the former made people
perceive safety, people may feel instability in the latter.
15.5.3 Terrestrial Vegetation
Some species need both terrestrial and aquatic habitats, and terrestrial areas perform
highly many ecosystem functions important to the provision of ecosystem service.
Terrestrial plants quality has an impact on the diversity of wetland, and landscape
aesthetic preference. Terrestrial plants area surrounds coastal wetland. As people go
into this setting, terrestrial plants area usually locates at middle-background, its
composition could make people perceives complexity and mysterious that induce
people go deeper to explore or not.
The terrestrial vegetation closely related to ecological aesthetic of coastal wetland that concerns with diversity, richness, evenness, and stratification of
vegetation.
Diversity, richness, and evenness of terrestrial vegetation provide availability of
information for people, and arise concerning people’s cognition aspects at coastal
wetland landscape. Their composition related to habitat quality and ecosystem of
wetland.
The diversity of species, age and shape of trees (Minckler 1980), and the vegetation diversity of grassland (Lindemann-Matthies et al. 2010), all have attractiveness
and high aesthetic valve at wetlands. The evenness make appreciation of coastal
wetland landscape is the coherent perception to people; that environmental information provides an understanding in the setting. The diversity and richness are considered about the complex and mysterious perception; that impels people goes deeper
into and explores this landscape.
Perceived species richness had a strong influence on people’s aesthetic appreciation, particularly in the evenness experiment (Lindemann-Matthies et  al. 2010;
Tilman et al. 2001), and increase visual complexity with increasing species richness
might explain the high aesthetic appreciate. Humans prefer landscape scenes with
levels of moderate to high complexity (Kaplan and Kaplan 1989; Kaplan et al. 1998;
Leder et al. 2004; Lindemann-Matthies et al. 2010; Ulrich 1986). People felt discomforted as the view is blocked in dense vegetation of swamp that wetland has rich
contents it lacks of clear focus. The plant diversity of swamp must be kept moderately mystery as much as possible. On the whole, diversity, richness and evenness
can help people make sense, and has effects on ecological aesthetic of coastal wetland (Photo 15.5a–d).
Psychological theories of aesthetic response are used to deduce a variable, i.e.
visual penetration. Stratification of vegetation means the arrangement of vegetation
in layers refers to vertical layering of a habitat. Terrestrial vegetation of coastal
wetland formed by upper story and under story; the visual penetration is better in
