“…The possible reason could be that Khanapur wetland was surrounded by a plantation of exotic plant Acacia auriculiformes (Australian Acacia), which might be the reason for the lower richness of wetland and wetland-associated birds. Exotic plants support fewer birds compared to natural vegetation and reduce the overall diversity of birds by affecting natural vegetation (Choudaj & Wankhade, 2021). It was seen that the diversity of both wetland and wetland-associated birds was lower at Ningudage wetland as compared to other wetlands.…”

Artificial wetlands are built to meet the rising human population's water needs, with little attention paid to their ecological significance. The current study was carried out to assess the importance of artificial wetlands in biodiversity conservation. Habitat quality of wetlands was assessed using the birds as an ecological indicator. Bird surveys were carried out at the five artificial wetlands located in the Ajara conservation reserve, northern Western Ghats, India. Bird surveys were conducted for five years (2011–2015). During the study, 165 bird species were recorded, including 34 wetland birds and 131 wetland-associated birds. Wetlands in forested areas have a higher richness of wetland birds. Wetlands surrounded by exotic plantations, agriculture, and human settlements exhibit lower wetland bird richness than wetlands in forested areas. Land use attributes around the wetlands affect wetland bird diversity. The current study gives a glimpse that these artificial wetlands could serve as a possible habitat for wetland birds.

“…South American grassland conversions to plantations are best studied, with significant effects shown in birds, mammals, amphibians, and reptiles (Brazeiro et al, 2018; Cravino et al, 2023; Dias et al, 2013; Jacoboski & Hartz, 2020; Saccol et al, 2017). In Europe and Asia, bird communities have shown significant shifts (Choudaj & Wankhade, 2021; du Bus Warnaffe & Deconchat, 2009). Not all plantations appear to significantly alter vertebrate communities, however, as other studies show only moderate or negligible impacts (Iezzi et al, 2020; Lantschner et al, 2009).…”

Decadienal afforestation and risks to montane grassland amphibians in the Udzungwa Plateau, Tanzania

et al. 2023

Human modification of the environment has drastically changed ecosystems around the globe. While forest‐loss (deforestation) has been well studied for its effects on ecosystems, afforestation also has major impacts. The Udzungwa Plateau in Tanzania is naturally a mix of forests and grasslands. However, non‐native pine plantations have recently increased in the area displacing the native grasslands of the montane plateau. In this study, we explored the effects of land use change on amphibian communities by comparing amphibian surveys before non‐native plantations were introduced (~2000) and after (2017–2019). To put these amphibian surveys into wider context across the plateau and to distinguish local population loss compared to plateau‐wide extinctions, we sample diversity at new sampling locations and locations with multiple surveys through time. We then assessed landscape change through remotely sensed data and ground surveys. Amphibian encounter surveys found approximately the same species diversity across all sampling locations, but local extinctions appear likely. Remaining amphibians appear to be limited to small refugia in non‐pine wetlands. Approximately half (45%) of the species found have limited distributional ranges (<72,000 km2) and are described as habitat specialists by the IUCN Red List. Monitoring pine plantation growth using remote sensing techniques suggested only limited extensions of plantations between 2000 through to 2013–2016, but ground surveys found small pines (<3 years old) throughout almost all areas identified as grasslands on satellite imagery. Our study highlights the plight of this narrowing biome on the African continent and calls for more research on the impact of non‐native plantations on natural communities.Abstract in Swahili is available with online material.

“…Nerlekar et al (2016) and Choudaj and Wankhade (2021a) studied the avifauna of premier academic institutions in Pune city, noted decline in richness of birds due to loss of suitable habitat. Exotic plantations over the native savannas of Pune city affected grassland birds (Choudaj & Wankhade 2021b). Small green spaces with native plants support more birds, but increasing percentage of exotic plants negatively affect them, especially the specialist ones (Choudaj & Wankhade 2022).…”

The green spaces in many urban areas are under severe threats; the area under green cover is declining, habitat quality is deteriorating due to fast urbanisation and the booming real estate market. Therefore, we investigated the avian richness of a natural remnant area and compared it with species richness data previously published in the literature about gardens, urban parks, and academic campuses in Pune, India. In two years of our survey, we recorded 65 species at the natural remnant site, 15 of which are rare considered in urban areas. Among recorded species, 17 are habitat specialists and 14 have declining population. Natural remnant patches are generally inaccessible to the general public; they have undergrowth of vegetation and aerial leaf litter, which may be the reason for the higher species richness and the occurrence of rare species. Our findings indicate that the natural remnant site in Pune has a unique and relatively rich assemblage of bird species, thus provide further support for the notion that natural remnant sites are valuable for urban biodiversity conservation. Therefore, we suggest that small, isolated patches of natural vegetation should receive more attention in conservation planning.
