Occurrence of Isoetes coromandeliana L.f. in natural ponds of Harni, Savali and Tuwa (India) is known since 1956 by earlier workers. Equisetum debile Roxb. ex Voucher was also reported in 1962 growing as wild at Savali. Available literature indicates that I. coromandeliana falls under the category of ‘near threatened’ in Asian continents and as an ‘endangered species’ at national (India) level. In the current field work study, the authors could not locate the investigated species from the locations earlier documented by researchers. Few saplings of I. coromandeliana were observed at Talod and Vaktapur near Gandhinagar, a new location for the species. In contrast, E. debile appeared to be lost in wild from Gujarat. Their extinction from earlier reported locations is associated with anthropogenic pressure and thus legal action for their protection is needed. The present paper suggests further survey and habitat based studies and recommends conservation and management action plans based upon the ecology of the habitat.

An intensive field survey was carried out from the hilly regions, plains of different climatic regimes and agricultural land of Gujarat state. About 23 species were collected from Gujarat state, from which eight species viz., Actiniopteris radiata (Sw.) Link, Adiantum caudatum L., A. incisum Forssk., Lygodium flexuosum (L.) Sw., Pteris vittata L., Selaginella ciliaris (Retz.) Spring, S. delicatula (Desv. ex Poir.) Alston, and S. repanda (Desv. ex Poir.) Spring. were added as new distributional record for the Gujarat state. Increasing anthropogenic pressure, destruction of forest ecosystem and development of infrastructure facilities including road widening and rainwater harvesting program by deepening of the natural ponds are additional reasons for declining terrestrial and aquatic pteridophyte diversity respectively. Our survey concludes that E. debile is regionally extinct in the wild while Isoetes coromandeliana, will be lost from its natural habitat in short time if not conserved properly. Therefore, there is an urgent need of in situ conservation by developing action plans in collaboration with the state forest department.

Abstract We present for the first-time data on fish assemblage structure for ten temporarily closed estuaries (TCEs) along the western coast of India. Fish community structure differed significantly between TCEs based on species presence/absence, estuarine use and feeding mode - differences based on estuarine surface area and geographical position (northern and southern locations). Marine migrant and freshwater stragglers dominated the ‘fish guilds’ in all estuaries, while piscivores and zoobenthivores were the major feeding guilds. We used the estuarine fish community index (EFCI) and a combined anthropogenic pressure index (CPI) to determine ecological quality of the TCEs. The application of functional guilds and EFCI could represent the use of TCEs by fish communities, and functional similarities existing between fish assemblages of these estuaries, despite considerable taxonomic, physical and chemical differences. Analysis of EFCI indicated that the ecological health of TCEs in south-western India ranges from “poor” to “good”. Through this index, we also established a significant relationship between CPI, EFCI and ecological quality in various TCEs (EFCI = A + (b X CPI)). Thus, the EFCI provides an integrated measure of the ecological status of fish community for TCEs along Indian coast.

Extensive fieldwork in different climatic regimes of Gujarat state during last four years resulted in the collection of more than 349 fungal species. Out of these, 37 species from 20 genera were found to be from the family Polyporaceae. Among these, five species are being reported for the first time here as new distribution records. The highest number of species is represented by the genus Trametes while, Cerrena unicolo, Neolentinus kauffmanii, Dichomitus squalens, Panus conchatus and Laetiporus sulphureus possessed single species each.

The Banni grassland, of Gujarat state of western India, has emerged as a site of multipronged contestations over land and livelihoods. Structural transformations seek to refashion Kachchh’s economy, society, and nature along capitalist and neoliberal lines threatening the livelihood of the 25000 mobile pastoralists inhabiting the grassland. Embedded within this context, the Salim Mama Youth Course, initiated through the a collaboration between local civil society, research and academic organizations, trains the youth in the region to recognize connections between pastoralism and their ecosystems. It achieves two main goals: firstly, the course attempts to secure the long-term sustainability of the grassland by developing the technical know-how of the youth as well as generating enthusiasm for pastoralism. Secondly, it contributes to the ongoing resistance against state induced corporate capture both practically, by providing information and tools to sustain contestations, and ideologically by reimagining the role and value of pastoralism in the region. This article unpacks the pedagogical approach of the course as a form of active and positive grassroots resistance against neoliberal environmentalism.

Cyrtandra argentii Olivar, H.J.Atkins & Muellner sp. nov., endemic to the Philippines and named after George Argent, is herein described and illustrated. Collections associated with this new species are often confused with three other species, namely C. ferruginea Merr., C. villosissima Merr., and C. hirtigera H.J.Atkins & Cronk. Distinguishing characters including keys, updated descriptions, distribution maps, and photos of live specimens are provided to aid identification of the four species. Following the International Union for the Conservation of Nature (IUCN) criteria, C. argentii sp. nov. is considered to be Near Threatened (NT) due to its distribution in a zone susceptible to anthropogenic pressure and the lack of any formal protection.

Sukla Phanta Wildlife Reserve lies in the southwest corner of Nepal. It has been listed as an important bird area and a number of bird studies have been conducted here. The reserve is an important refuge especially for many grassland birds, several of which are globally threatened. The high, total of 15 globally threatened and 13 near-threatened bird species occur in Sukla Phanta. Some of the bird species reach their world limit of distribution at Sukla Phanta. Of all the habitats found in Sukla Phanta, grassland is the most important. Conservation and management of grasslands that are sympathetic to bird populations are urgent at Sukla Phanta.
