“…Relatively, this number is higher than that recently reported by Widyastuti et al (2018) for mangrove in Segara Anakan, Central Java, Indonesia, and also reported by Cañizares and Seronay (2016) for the mangrove richness in Barangay Imelda, Dinagat Island, Philippines. The number of 21 species as biological wealth of true mangrove species in North Gorontalo is almost comparable with that reported by Barik and Chowdhury (2014) for diversity in the Sundarbans Delta, West Bengal, Eastern India, and also that reported by Wouthuyzen and Ahmad (2018) in the Lease Islands (Saparua and Nusalaut Islands), Maluku Province, Indonesia.…”

Kasim F, Kadim MK, Nursinar S, Karim Z, Lamalango A. 2019. Comparison of true mangrove stands in Dudepo and Ponelo Islands, North Gorontalo District, Indonesia. Biodiversitas 20: 259-266. This study aimed to investigate and compare the current status of mangrove areas, as well as the composition and species diversity of mangrove stands in both regions of Dudepo and Ponelo Islands. The results showed that the mangrove areas calculated using the segmentation method in classifying image of Landsat-8 OLI (acquisition on September 2017) were 279.46 ha (Dudepo Island) and 113.35 ha (Ponelo Island) respectively. A total of 13 species of true mangrove were recorded from both islands, using survey method from 9 transect lines (TL), with a distance ranging from 40 to 210 meters (1-6 quadrats) per transect. The mean densities of trees were 2133 ± 329.78 ha-1 (Dudepo Island) and 2111 ± 234.28 ha-1 (Ponelo Island), while those of saplings and seedlings were 58 ± 13.48 ha-1 and 1425 ± 113.96 ha-1 (Dudepo Island), and 79 ± 14.51 ha-1 and 2963 ± 443.22 ha-1 (Ponelo Island). The mean diameter and basal area were 19.73 ± 10.65 cm and 84.22 ± 67.67 m2ha-1 (Dudepo Island), 17.04 ± 1.46 cm and 60.07 ± 15.12 m2ha-1 (Ponelo Island), respectively. The Importance Value Index (IVI) ranged between 3.97-114.87 (Dudepo Island) and 6.04-82.18 (Ponelo Island). The dominant and codominant species based on IVI in both islands were Rhizophora apiculata Blume and R. stylosa Griff. The indexes of diversity, richness, and evenness of mangrove species in both islands were 0.34-1.70, 0.48-1.18, 0.47-0.94 (trees), 0.00-1.10, 0.00-1.82, 0.00-1.00 (saplings), and 0.00.-1.48, 0.00-1.44, 0.72-1.00 (seedlings), respectively. The Bray-Curtis similarity index between Dudepo and Ponelo Islands, based on the overall values of community attributes, was 0.75.

“…The Sundarban mangroves belong floristically to the Indo-Andaman mangrove province within the species-rich Indo-West Pacific group [26]. According to [27], 24 true mangrove taxa belonging to nine different families are found within the Indian Sundarbans. Several species are endemic such as Aegialitis rotundifolia, Heritiera fomes, Sonneratia apetala or S. griffithii.…”

The Indian Sundarban Mangrove Forests: History, Utilization, Conservation Strategies and Local Perception

Covering approximately 10,000 km 2 the Sundarbans in the Northern Bay of Bengal is the largest contiguous mangrove forest on earth. Mangroves forests are highly productive and diverse ecosystems, providing a wide range of direct ecosystem services for resident populations. In addition, mangroves function as a buffer against frequently occurring cyclones; helping to protect local settlements including the two most populous cities of the world, Kolkata and Dhaka, against their worst effects. While large tracts of the Indian Sundarbans were cleared, drained and reclaimed for cultivation during the British colonial era, the remaining parts have been under various protection regimes since the 1970s, primarily to protect the remaining population of Bengal tigers (Panthera tigris ssp. tigris). In view of the importance of such forests, now severely threatened worldwide, we trace the areal change that the Indian Sundarbans have undergone over the last two-and-a-half centuries. We apply a multi-temporal and multi-scale approach based on historical maps and remote sensing data to detect changes in mangrove cover. While the mangroves' areal extent has not changed much in the recent past, forest health and structure have. These changes result from direct human interference, upstream development, extreme weather events and the slow onset of climate change effects. Moreover, we consider the role of different management strategies affecting mangrove conservation and their intersection with local livelihoods.

“…Halophytic species, even though they grow in high saline soils and exhibit succulence, resort to various other physiological adaptations to overcome the adverse effect of salt stress. Apart from the Indian arid zone, Indian shorelines are essential habitats of some Indian halophytes and mangrove vegetation (Barik and Chowdhury 2014) . The Gulf of Kachchh in Gujarat, a semi-enclosed coastal region, is predominantly inhabited by mangrove ecosystems, coral reefs, abundant marine diversity, and terrestrial riparian vegetation.…”

Halophytic plants thrive well in the environments characterized by excess salt ions, even at toxic concentration, particularly sodium and chloride, due to their efficient biochemical tolerance mechanisms. These adaptation mechanisms may not be limited to high salt concentrations but may confer tolerance to other toxic ions, including heavy metals. Several studies have documented the ability of halophytes to tolerate and accumulate high levels of heavy metals, making them excellent candidates for phytoremediation of contaminated soils. This chapter details the overview of halophytes in India and their phytoremediation strategies.
