Biodiversity of Avian Fauna of Vansda National Park, Gujarat: Conservation Issues
2015
Kumar Vikas
The Vansda National Park is situated in Navsari in South Gujarat. It has a unique identity because the Park falls on the northern-most limit of the Western Ghats, and is famous for the biodiversity of flora and fauna, especially for birds, such as Indian great black woodpecker, heart-spotted woodpecker, lesser golden backed woodpecker, grey hornbill, spotted munia, racket-tailed drongo and pheasanttailed jacana, etc., which have become extremely rare species, but are fairly common in the Dang’s forest. The majority of birds are observed during the winter followed by rainy and summer season. The area is inhabited by more than 99 different type of birds, out of these 28 are residential migratory or local migratory, 10 are migratory, 4 are water migratory and 57 are resident. Family Accipitridae was found as dominant containing maximum species (15) followed by Ardeidae (9), Phasianidae (7), and Anatidae, Dicaeidae, Muscicapidae, Rallidae and Sturnidae (4). About 50 per cent of all the species recorded have been insectivorous. Based on the frequency of occurrence and the numbers of different species encountered, it was found that a large number of bird species occur with a small population.

S. Ivanova and A. Prosekov
The study was carried out on the territory of the Kemerovo region-Kuzbass (Western Siberia, Russia). The purpose of the study was to obtain information on the species diversity and population of big-game animals. The monitoring was carried out on the forest territories of the region’s administrative districts. In the course of remote sensing using an unmanned aerial vehicle, the presence of all types of animals under consideration, except for the bear, was recorded. The deviation of the population number determined using the traditional method of digital technologies varied up to 50%. It was established that environmental measures organized and carried out by the regional administration and hunting farms improved the situation and stabilized the population of the main group of game animals. It was found that when using a sufficiently high sensitivity of the thermal imager (the used thermal imager had a very high sensitivity class ≤ 60 mK at 300 K), long-haired animals, which are characterized by a lower intensity of thermal radiation (for example, wolves) are identified and recognized in the images. The larger the animal and the worse the thermal insulation layer (wool or feathers), the easier it is to identify it in infrared images and the lower the sensitivity requirements of thermal imagers. The ability to recognize and record smaller animals and birds requires additional research on existing technologies. Our research has confirmed the validity of digital remote monitoring methods for managing the wildlife of hunting farms and nature conservation areas of the Siberian Taiga territories.

The objective of the present study was to prepare a record of the Residential, IUCN and WPA status of the birds recorded in four sites of Indore city. The study was of one-year duration (2018). The results showed that there were five species as winter migrants, one as summer migrant, six as local migrants, and 46 as resident species. Only one species, i.e. Psittacula eupatria was found to be in the near threatened category. According to WPA status, 5 species were Schedule I species, 1 schedule V, and 52 species as schedule IV species. These sites have a potential of augmentation of avian fauna shortly and these spaces abide by many species with a larger diversity than estimated. The present study is the first-ever record of avian species in the three sites of Indore city. The results of this study support the scope of conservation of these spaces for increasing the number of species shortly.
