    Opis:
    Conserving biodiversity is a major necessity, as human interference causes loss of this. Tourism is not exempt from this. Still, ecotourism, a sub-component of the field of sustainable tourism, has more positive effects. The primary objective of this work is to ascertain the condition of ecotourism in the study area. The secondary objectives are to identify the challenges and progress of biodiversity by way of ecotourist activity, and to suggest solutions to promote best outcome and to overcome the challenges of ecotourism. China Bay (Marble Beach), Kanniya Hot Wells, Nilaveli Beach, Pullmottai Beach (Arisimalai), Lanka Patina and Trincomalee Beach are renown places for tourism in Trincomalee District. The condition of the ecotourism industry in Trincomalee District was identified by means of questionnaire survey and direct observation. Our work shows that the coastal areas are particularly rich in biodiversity and in offering scenic values. Many environmental challenges were identified and remedial measures, suggested.

    Opis:
    The extraordinary knowledge of indigenous people about their immediate environment and natural resource base can be a great asset for conservation of biodiversity. The current study aims to investigate an indigenous method of grazing management through temporary confinement of Mithun (Bos frontalis) of whole village community in a well selected area in the forest during the cropping and growing season. The whole system is called Lura and practiced by Galo tribes of Eastern Himalayan region of India. Every year Lura management committee is formed that selects a new site based on number of Mithuns, forage availability, time period and several other key criteria without affecting flora-fauna diversity and rare medicinal plants. The practice checks continuous, free, random and selective grazing by Mithuns. It prevent continuous disturbance of soil surface due to treading, during growing and rainy seasons that avoid soil erosion and compaction, and facilitate seedling germination and the invasion by plants. Change of site, provide resting period to the forages in the previous Lura site especially during growth stage that allow them to renew and regenerate appreciably within 1-2 months. It also saves resources and time for construction of fencing in each Jhum and other agricultural site of each farmer. The confinement offers easy monitoring, protection and regular health assessment of the livestock. Thus, it is a multifaceted indigenous practice that ensures grazing management, biodiversity conservation, protection of standing agricultural crops and animal health management

    Sacred Grove
    Opis:
    Devi Satkanya Sacred Grove is located behind a mistic town called Lebong as a pristine forest patch, about 8 km from Darjeeling Town. Geographically, the grove is located between 27°03.436’N Lat. and 88°16.592’E Long. at an altitude of about 1823 m. Total area of the grove is approx. 5770 square metre (sq.m.). In Darjeeling, most of the Sacred Groves have ‘deity’---rocky idols of Devi Durga and Lord Shiva, often reside inside small rocky caves called ‘cave temple’. Devi Satkanya Sacred Grove possesses a great heritage of diverse gene pool of many forest species having socio-religious attachment and possessing medicinal values viz., Garcinia cowa DC., Prunus cerasoides D.Don, Michelia cathcartii Hook.f. & Thomson (Chanp), Ficus nemoralis Wall. etc. Devi Satkanya SG is ecologically and genetically very important. It harbours a good number of Endangered ethnomedicinal plants like Swertia chirayita (Roxb. ex Fleming) H. Karst. and animals like Himalayan Salamander (Tylototriton verrucosus Anderson). As a result of extensive field visits in different seasons to Devi Satkanya SG from June 2014 to October 2016, new and first hand data on threatened plants and animals, ethnomedicinal plants and traditional and magical way of biodiversity conservation by the local Nepalese since time immemorial were documented.

    Opis:
    This study highlights the 75 species of dragonfly fauna associated with rice ecosystems in eastern India out of which 15 species were regular and rest were sporadic. From the general taxonomic point of view all the species were grouped under 5 families of under order Odonata. Comparing different body parts the double branching keys were prepared for easy identification of 15 common dragonfly species recorded in rice ecosystems of West Bengal. Each key begins with a couplet (a pair of alternative) and each of which leads to another couplet. Finally the reader reaches the specific identity of species. Free hand drawing of wings of the 50 dragonflies were also used for separate identification of these insect species. In addition to this, different studies were made on courtship and mating, egg laying habitats, nymphal development, longevity, flight capacity of dragonfly to make the study more interesting to the reader. The population build up of dragonfly, favors to certain altitude as well as availability of water which is reverse to the other group of insects. Three different localities were selected at 9.75 m (Chakdaha), 200 m (Cooch Behar) and 1250 m (Kalimpong) of which former two represent an unique physiographic ecological system in Eastern India characterized by extreme diversities of dragonfly inhabiting there. The studies on natural enemies of dragonfly along with their major threats indicated that about 2, 4 and 4 species were critically endangered, endangered and vulnerable in rice ecosystem of West Bengal. Dragonflies are very sensitive to changes in landscape and are reliable indicators of wetland health. Therefore the effective conservation of dragonfly depends entirely on conservation of their habitats. Different studies were made to estimate the role of dragonfly in integrated pest management of rice crop in West Bengal. An investigation was also carried out to find out the crop stage wise diversification of individual predator and found that dragonfly was more diverse during flowering to ripening stages of crop respectively. The values Simpson and Shanon diversity index showed that dragonflies are specific flowering to ripening stage of crop. Subsequently the value of Margalef index and Menhinick index also indicated that the aforesaid predators were more diverse in flowering stage of crop whereas it was least in vegetative stage of crop. From the Hill's diversity the number of abundant and most abundant species was calculated where maximum and minimum were obtained from dragonfly and staphylinid respectively. The studies on colonization and succession of major dragonfly taxa in the rice field indicated that it followed a uniform pattern in relation to growth stages as well different phases in the rice field. The studies on relative abundance of dragonfly in different ecosystems reflected that their population in fields could be conserved and enhanced through maintenance of rice weed flora on bund or allowing ratoon rice after the rice crop during fallow period. The fallow land has limited effect on incidence of insect predator in rice crop. The relative ranking chart of 50 important predators in rice ecosystem of West Bengal indicates that the insect belonging to Coleopteran (17) were top of the list whereas dragonfly was third (10). The validity of chart may increase over time and they will need to be updated periodically.

    Opis:
    The Chandipore beach, situated in Balasore district, Odisha, 21°28΄N 87°01΄E / 21.47°N and 87.02°E shows an interesting nature of wave action as the water recedes up to an average of 5 kilometres during the ebb and tide, resulting in a vast, dynamic array of coastal biodiversity. It gets exposed to a huge tourism load every year and is faced with multidimensional anthropogenic interactions manifested through a varying gradient of urbanizing parameters like cattle grazing, automobile exhaust, constructions in vicinity of beach area, sewage and solid disposals etc. Present piece of work aims at documenting the premonsoon abundance and diversity of marine invertebrate fauna in this eastern Indian sea beach. Adamsia palliata, Carcinoscorpius rotundicauda, Diogenes rectimanus, Sabella sp., Astropecten mauritianas were found to be few of the prominent faunal representatives. Significant differences in respect of species richness have been observed among different selected ecozones through the coastal landscape based on tidal activity and anthropogenic exposure (F5.73, p ≤ 0.05). Such type of field-based observations leads to the scope of further estimation of the ecological status of these native organisms, their intra and inter-specific associations and functional contributions to coastal landscape playing role as a potential bioindicator, which may in turn become instrumental in frame working the future conservation scheme of these natural assets.

    Opis:
    Salt licks play an important role in the health of wildlife by supplying the essential minerals required especially for herbivores. This study assessed nine mineral salt lick sites, fauna utilization and tree species diversity in response to threats encountered at the site. Systematic random sampling, quadrat sampling and transect survey were used as the methodological indices to carry out the research. The dominant tree species is Anogeissus leiocarpus while recessive species was Vitellaria paradoxa. Fauna distribution and abundance within and across mineral salt lick sites were observed. Kobs (Kobus kob) were highest while Tantalus monkey (Chlorocebus tantalus) and Warthog (Phacochoerus aethiopicus) had least encounter rate. Park management should implement conservation education, stringent policies against wildlife offences and constant surveillance to conserve biodiversity in protected ecological site. The overall benefits derived from salt licks for wildlife health, majorly through herbivores are crucial in maintaining a healthy wildlife community for their reproduction and survival.
