Present study revealed that Avicenniaceae is most dominant mangrove family in all selected sites Avicennia marina was the most frequent, most abundant and most dominant species in all selected sites.…”

“…The moisture contents (mean values) were 23.7% (Surat), 44.4% (Bhavnagar) and 60.1% (Navsari). High moisture content at Navsari can either be due to freshwater input of Purna river or frequent tidal inundation (Ashton & Macintosh DJ 2002). It has been observed that 44.4% moisture content is more suitable for plant density at Bhavnagar site where as on other sites with less and more moisture content plant density was less.…”

Mangrove forests are of utmost importance due to their role in preventing extreme weather events like tsunamis and cyclones etc. The present study aimed to observe the mangrove plant diversity and edaphic characteristics from Gulf of Khambhat, Gujarat. Ecological parameters and edaphic characteristics were studied for different sites i.e. Navsari, Surat and Bhavnagar. Avicennia marina was found as dominant species at all study sites. Plant species diversity shows increasing tendency with the decrease in plant density. Important Value Index, Shannon-Weaver diversity index and Simpson index of dominance of the mangrove species across the study area were also determined. The present study provides the baseline data of mangrove species and concludes the need of detail study for mangrove species in Gulf of Khambhat, Gujarat for conservation and management strategies.

“…They explained that their results did not support expectations from decades of studies documenting local zonation in mangrove forests. Ashton and Macintosh (2002) mention tree similarity matrices and univariate measures have shown a complex interplay of factors (e.g. soil, pH, salinity etc), governing species distribution in the Sematan mangrove forest in Malaysia.…”

“…The site is located about 18 km from the estuary to South China Sea, making it categorized as landward zone of mangrove habitat. In the case of Kuap River, Nypa fruticans which is indigenous to this region [12] dominates the water edges ( Figure 3). In its most pristine conditions, they form unbroken swampland, often stretch miles into the land.…”

Developments adjacent to river, over the years, have impacted the ecological systems along riparian zones. This paper is to explore the changes occurring in a populated riparian zone. For over 35 years, the nipah swamps along the study site at the edge of Kuching city, Sarawak, Malaysia are subjected to human disturbances. Once a nipah forest is dominated by Nypa fruticans, the study site is being replaced by Sonneratia caseolaris-a mangrove forest. Both plants are indigenous to Southeast Asia region. We observe in the study site that Nypa fruticans, habitually a dominant species, is weakened when human disturbances are high, and leads to event taken over by Sonneratia caseolaris. We point out that Sonneratia caseolaris behaves intrusively rather than neighborly in disturbed systems. Here, we suggest that the plant also has high resistance towards human disturbances. This is a growing behavior contradictory to reports of Sonneratia caseolaris in natural systems. KeywordsMangrove, Nipah Swamp, Nypa fruticans, Sonneratia caseolaris, Urban River BackgroundHuman activities increasingly either degrade ecosystems, leading to harsher abiotic conditions and/or more limited dispersal of the species originally present; or introduce new species which alter the biotic environment and potentially reduce chances for system redevelopment. In both situations, novel ecosystems can be expected [1]-[3]. This paper is to gain understanding of the mentioned changes in a populated riparian zone because this would allow people to identify, proactively address specific concerns and monitor changes over time.Riparian zones are the interfaces between terrestrial and aquatic ecosystems, and host a wide array of plant and animal life [4]- [6]. Understanding of terrestrial-aquatic interactions is critical for assessing ecological effects of development because human settlements are often clustered near such areas [7] Study SiteLocated at the eastern edge of Kuching city, the study site is near Muara Tabuan Light Industrial Park. The industrial park is beside the confluence point of tidally-influenced Tabuan and Kuap Rivers (Figure 1). Earliest development of this area was traced to 1978 with the construction of a manufacturing plant, followed by housing estates and villages nearby. It was once a nipah swamp, characterized by nipah palms or Nypa fruticans lining the banks of Kuap River. For over 35 years, the nipah swamps along the two rivers are subjected to human interventions [10]. It is for this reason that makes this area an ideal site to have an investigation on its characteristics. A total of 22 polygons of 100 m × 100 m are delineated along the riparian strip for analysis. Some intact nipah swamps are still thriving on the opposite bank of the industrial park, allowing comprehensible comparison to the polygons being studied. Field InvestigationBorneo Island is one of the many islands dotted the western Indo-Pacific region. As such, the typical mangrove zones depicted in Figure 2 holds true for the study site [11]. The site i...
