“…In addition, the higher sales price for dead mangrove wood and the preference for mangrove firewood may make it more attractive for people to collect it illicitly. Similarly, other scholars have found that an illicit trade exists in the region (Carney et al, 2014;Fent et al, 2019).…”

“…High levels of mangrove fuelwood collection may also have negative implications on the environment, as was found by other scholars (Carney et al, 2014;Fent et al, 2019). The practice of "bois tu� e" in particular may be damaging.…”

“…Mangroves are one of the most threatened global ecosystems (Duke et al, 2007;Walters et al, 2008). Approximately one-third of the mangrove cover in the Sine Saloum Delta was lost between 1972and 1986(Conchedda et al, 2011Balla Dieye et al, 2013;Fent et al, 2019). Although many factors are behind mangrove loss, humans largely contribute to the threatened state (Walters et al, 2008).…”

Dahdouh-Guebas. Mangrove use and management within the Sine-Saloum Delta, Senegal. 2019. Mangroves constitute one of the most complex and productive ecosystems in the world. This study explores mangrove use and management within the Sine-Saloum Delta, Senegal. It utilizes field-based, mixed research methods, drawing primarily on quantitative survey data, supplemented with qualitative data from semistructured interviews, personal communications with villagers, and participant observation from August-December 2013. Research results indicate that use of dead mangrove wood for fuelwood is the most important extractive use of mangroves within the Delta. Fish, clam, oyster, and shrimp collection is the second most important use of mangroves in the region. Senegal's Forest Code Law notwithstanding, ambiguity remains in mangrove management and adequate means are lacking for protection of mangroves within the Delta. Study results show that mangrove reforestation is a robust activity in the region, and that financial incentives from international organizations and NGOs are significant in motivating community involvement. Study results suggest that mangrove plantings may have a low survival rate, however further investigation is needed.

“…Moreover, the selective cutting of mangrove trees in Bansud, Roxas, and Bulalacao as well as the increase in population near these mangrove areas can impact mangroves' recovery since these areas are open access to community. It has been reported that the source of mangrove degradation is directly accounted to the local residents (Fent et al 2019). Possible impact would be crushing and trampling of young plants due to constant access.…”

Regeneration capacity and threats to mangrove areas on the southern coast of Oriental Mindoro, Philippines: Implications to mangrove ecosystem rehabilitation

Abstract. Raganas AFM, Hadsall AS, Pampolina NM, Hotes S, Magcale-Macandog DB. 2020. Regeneration capacity and threats to mangrove areas on the southern coast of Oriental Mindoro, Philippines: Implications to mangrove ecosystem rehabilitation. Biodiversitas 21: 3625-3636. Regeneration capacity is important as it determines the fate of an ecosystem. This study assessed six mangrove areas in the southern coast of Oriental Mindoro, Philippines to evaluate their regeneration capacity status. Four mangrove ecotypes were delineated namely seaward, middle, landward and riverine zones at each mangrove ecosystem, where dominant mangrove species were identified and selected for regeneration capacity study. Three subplots measuring 1 x 1 m2 were laid within the five 10 x 10 m2 survey plots established per zone. The juveniles were counted and categorized according to their height classes, using linear regeneration sampling method; where: RCI (≤40 cm) considered seedlings; RCII (41-150 cm) as saplings; and RCIII (151-≤300 cm) as small trees. Potential threats both anthropogenic and natural were determined through key informant interviews. Seven dominant species were identified across ecotypes in all mangrove sites, namely Avicennia marina, Avicennia rumphiana, Ceriops decandra, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Xylocarpus granatum. RCI (seedlings) is the most abundant across mangrove sites irrespective of the dominant species. Fishpond operation within the mangrove stand is considered a major threat to the juveniles and most mangrove ecosystems. Therefore, protection and constant monitoring of these mangrove ecosystems are necessary to ensure regeneration success in the future.

“…So far, a unanimous awareness, which it is difficult to achieve conservation effectiveness of cross-border WPAs only by one single country enforcing efforts, has been recognized in the worldwide [31]. Thus, it is informative and significant to conduct cross-border studies on wetland monitoring and assessment because such investigations will help determine how wetland dynamics are driven by differing socio-economic and political conditions, develop knowledge-based wetland conservation and management strategies on behalf of neighboring countries, as well as provide references on future cross-boundary wetland studies [32,33].…”

Comparative evaluation of cross-boundary wetland protected areas is essential to underpin knowledge-based bilateral conservation policies and funding decisions by governments and managers. In this paper, wetland change monitoring for the Wusuli River Basin in the cross-boundary zone of China and Russia from 1990 to 2015 was quantitatively analyzed using Landsat images. The spatial-temporal distribution of wetlands was identified using a rule-based object-oriented classification method. Wetland dynamics were determined by combining annual land change area (ALCA), annual land change rate (ALCR), landscape metrics and spatial analysis in a geographic information system (GIS). A Mann–Kendall test was used to evaluate changing climate trends. Results showed that natural wetlands in the Wusuli River Basin have declined by 5625.76 km2 in the past 25 years, especially swamp/marsh, which decreased by 26.88%. Specifically, natural wetlands declined by 49.93% in the Chinese section but increased with an ALCA of 16.62 km2/y in the Russian section during 1990–2015. Agricultural encroachment was the most important reason for the loss and degradation of natural wetlands in the Wusuli River Basin, especially in China. Different population change trends and conservation policies in China and Russia affected natural wetland dynamics. The research offers an efficient and effective method to evaluate cross-boundary wetland change. This study provides important scientific information necessary for developing future ecological conservation and management of cross-boundary wetlands.
