“…In this scenario, artificial wetlands can play an important role in maintaining biodiversity (Cardoso and Loures-Ribeiro 2017). Reservoirs are noteworthy among these environments as they provide habitats for several wetland-dependent species, particularly waterbirds (Sebastián-González et al 2010;Murillo-Pacheco et al 2018).…”

Artificial wetlands can play an important role in waterbird conservation due to habitat loss and degradation of natural wetlands. Urban reservoirs can harbor waterbird communities, but they usually have lower biological diversity than natural wetlands. However, the value of reservoirs for waterbird conservation in urban areas needs further exploration. Here, we surveyed the waterbird community in a water-level controlled reservoir of an urban area in southeastern Brazil. We evaluate the seasonal variation in species composition, richness, and abundance. Monthly samplings were carried out between July 2017 and February 2018, through a boat line transect. A total of 7762 waterbirds were recorded, belonging to 32 species and 16 families. There were significant differences in species composition and abundance between dry and rainy seasons. The community was dominated by generalist and resident species, which Gallinula galeata and Jacana jacana were the most abundant species. We did not register migratory shorebirds during the surveys. Our results highlight the importance of reservoirs in urban areas, as they harbor feeding areas and breeding sites and may serve as refuges during dry seasons for resident waterbirds. We suggest management strategies to improve the importance of waterlevel controlled reservoirs as breeding areas for resident species and migratory stopover for shorebirds. Our results may also be considered for urban planning and waterbird conservation in urban areas.

“…The extent of wetland loss ranges from minor losses in boreal region countries to >90% losses in parts of Europe [4] and New Zealand [5]. This reduction in wetlands, which animals rely on for foraging, breeding, and nesting habitat [6,7], combined with increasing nutrient inputs from agricultural land use, has resulted in major eutrophication and biodiversity loss [8]. Conversely, restoring natural wetlands and establishing constructed treatment wetlands can provide environmental benefits, including buffering runoff, reducing erosion, attenuating nutrients and other contaminants, and mitigating biodiversity loss [9,10].…”

In agricultural landscapes, free-water surface flow wetlands (FWS) are constructed mainly to improve water quality; however, their contribution to biodiversity conservation is increasingly recognised. To inform biodiversity management in FWS treating agricultural runoff, we surveyed the vegetation and fauna assemblages in five established FWS in a lowland, pastoral landscape in the central North Island, New Zealand. The FWS had been established for between 3 and 19 years, planted with a restricted range of native plant species, and fenced to exclude livestock access. Larger wetlands hosted significantly more plant and mammal species. However, other than wetland size, we found few other significant relationships between wetland habitat, landscape characteristics, and measures of biodiversity (total species, proportion of native species, number of wetland specialists, or threatened species). We recorded one-hundred and thirteen plant, twenty bird, five mammal, eighty-five terrestrial invertebrates, forty-seven aquatic invertebrates, six fish, and two amphibian species inhabiting the FWS. Native species comprised 96% of the total aquatic invertebrate fauna identified. For other taxa, native flora and fauna accounted for half or less than half of all species identified: 53% terrestrial invertebrates, 50% fish, 45% birds, 32% plants, and 0% amphibian and mammal species. Few wetland specialists (aquatic or wetland-adapted) or threatened native species were detected, probably reflecting the limited range of wetland plant species in initial plantings and the difficulties native taxa face when colonising new habitat where potential reservoirs of colonist species are also depauperate or too distant. FWS support native biodiversity, but further enhancements may require active management of exotic and pest species to minimise competition or predation on native species.

“…However, some studies have found that human-influenced wetlands could provide alternative, complementary habitats for some species ( Fidorra et al, 2016 ; Giosa, Mammides & Zotos, 2018 ; Kloskowski et al, 2009 ; Li et al, 2013 ; Márquez-Ferrando et al, 2014 ). In some cases, the transformation from natural to human-influenced wetlands has increased bird diversity due to enhanced habitat heterogeneity ( Murillo-Pacheco et al, 2018 ). Also, aquaculture commercial fishponds can provide essential feeding grounds for waterbirds ( Navedo et al, 2015 ; Ramirez et al, 2012 ).…”

Spatial ecology of little egret (Egretta garzetta) in Hong Kong uncovers preference for commercial fishponds

Many natural wetlands have been converted to human-influenced wetlands. In some instances, human-influenced wetlands could provide complementary habitats for waterbirds, compensating for the loss of natural wetlands. Inner Deep Bay in Hong Kong is composed of both natural and human-influenced wetlands and is under immense development pressure. From an ecology perspective, we need to understand if different wetland types play the same ecological role. To achieve this, we tracked nine little egrets (Egretta garzetta) using GPS loggers for 14 months to study their spatial ecology, home range, movement and habitat use. We found that over 88% of the home range of all individuals comprised of wetlands (commercial fishponds, mangrove, gei wai, channel, and intertidal mudflat). Among these wetland types, nearly all (seven of nine) individuals preferred commercial fishponds over other habitats in all seasons. Little egrets exhibited seasonal movement and habitat use among seasons, with largest home range, greatest movement, and most frequent visits to commercial fishponds in winter compared to spring and autumn. Our results highlight the significant role of commercial fishponds, providing a feeding ground for little egrets. However, other wetland types cannot be ignored, as they were also used considerably. These findings underscore the importance of maintaining a diversity of wetland types as alternative foraging and breeding habitats.
