Aim: The study aimed to investigate tree diversity in Kuldiha wildlife sanctuary of Odisha. Twenty (20) plots of 100 sqm each were established in three different disturbed zones within the forest. Methodology: Important quantitative analysis such as density, frequency and abundance of tree species were determined along with the diversity indices wh...

... the present study, Sorensen's index of similarity (IS) among the three study sites varied between 5.254 % and 11.018%. The value of similarity (IS) of the tree species between periphery and buffer region was found to be highest (11.018%) followed by the value (7.211%) between buffer and core region ( Table 5). This low value of similarity can be attributed to the varying degree of disturbances between the core and the periphery area. ...Similar publications
Las plantas acuáticas, las semiacuáticas y la vegetación riparia presentan una amplia distribución en términos globales, regionales y locales, además de una gran diversidad asociada a cambios de posición geográfica y de condiciones fisicoquímicas de los sistemas. El presente estudio se desarrolló en tres estaciones ubicadas en las cabeceras de tres...

... A similar observation was made by Sarma (2002) and Sarma et al. (2010) in the mined areas where majority of the species showed contiguous pattern of distribution. In India, several workers (Majumdar and Datta 2015;Shameem et al. 2017;Saravanan et al. 2019) have reported similar distribution patterns in the forest vegetation. ...
This study assessed changes in herb, shrub and tree composition of Coal mining-affected forest (CMAF) area in relation
to a community reserve forest designated as Non-affected forest (NAF) of Changki village, Nagaland, Northeast India.
In all the three plant life forms, Shannon-Wiener index, Simpson’s diversity index and Margalef richness index showed
higher species diversity and richness in NAF compared to CMAF while Sorenson’s index reveals a low species similarity between the sites. Pielou’s evenness was higher at NAF and a contiguous pattern was prominently distributed in both
the forest. The family Poaceae, Asteraceae and Cyperaceae dominated the CMAF while Euphorbiaceae, Rubiaceae and
Poaceae dominated NAF. The NAF has greater plant density compared to CMAF and the IVI shows the dominant status
of native tree Terminalia myriocarpa in the Northeastern tropical forest. Weeds like Ageratum conyzoides, Bidens pilosa
and Drymaria cordata were prominently distributed in CMAF while Abarema clypearia, Inula cappa and Strobilanthes
coloratus has been obstructed by mining. The result imparted that the plant diversity of Nagaland tropical forests are under
threat due to coal mining which has reduced the vegetation diversity and induce the loss of dominant plant species. As
such, regulation of mine waste, land reclamation projects, robust forest management and bioremediation can be scientifically integrated to reduce the mining repercussion effects. Moreover, the result emphasizes the need to impart the tribal
knowledge of preserving natural forest to the upcoming generations and develop conservation strategies to prevent further
degradation or loss of biodiversity in this part of the Indo-Burma hotspot region.

... The IVI depicts the importance of the species in terms of its dominance and ecological success (Misra 1968). The change in IVI among the study sites can be attributed to the change in species composition and degree of disturbance and altitude (Saravanan et al. 2019). ...
... Rout et al (2018) recorded 38 numbers of tree species from 0.4 ha sample area at Kuldiha WL sanctuary. Saravanan et al (2019) reported presence of 35 species in periphery zone, 63 in buffer zone and 105 in core zone of the sanctuary including seedlings and saplings class. The observation of 43 species per hectare in this study was due to location of study site in between core and peripheral zone, size of sampling unit, consideration of individuals having GBH ≥30 cm in tree class count and season of study. ...
... It helps ecologist in prioritizing species for conservation whereby species having low IVI value need immediate attention compared to the ones with high IVI (Kacholi 2014). The high IVI exhibited by (48.70) was largely Shorea robusta due to higher relative frequency, density and basal area compared to other species which is very close to the observations by Saravanan et al (2019) in peripheral zone in the same sanctuary (IVI-55.647) and at par with reporting of Sahu et al (2007) for tropical forest in Odisha (IVI-43.88). ...
... and at par with reporting of Sahu et al (2007) for tropical forest in Odisha (IVI-43.88). Shannon Index of diversity (H ) for trees calculated for the ' present set of observation (4.81) was close to earlier observations (3.11 in buffer to 4.332 in core region) of Saravanan et al (2019). It is also comparable to the reported range 3.76-3.96 ...
Phyto-sociological analysis of vegetation in Kuldiha revealed presence of Wildlife Sanctuary 43 numbers of tree species (37 genera and 23 families), 12 numbers of shrub species (12 genera and 11 families) and 17 numbers of climbers (14 genera and 10 families). Shorea robusta, Syzygium cumini, Terminalia tomentosa, Schleichera oleosa Madhuca indica and were the predominant tree species having important value index 48.70, 19.13, 17.50, 15.84 and 14.46 respectively. The forest stand density was 488 trees ha with basal area m-1 2 36.17 ha. The Shannon-Weiner index of diversity for trees, shrubs and climbers was Simpson Index of-1 4.81, 1.41 and 1.15, respectively. The dominance, Margalef index for species richness and Pielou index for species evenness were also calculated. Many species were found rare and clumped pattern of dispersion was predominant among trees. The population structure of tree species showed reverse J-shaped pattern. Sapling and seedling density was 350 numbers ha and 50750 numbers ha respectively. Overall regeneration status of the forests was-1-1 fair.The study will be helpful in understanding changes in the plant community and there by developing location specific strategies for conservation of valuable rare plants of the sanctuary as well as sustainable utilization of biodiversity in future.
The Asian elephant's (Elephas maximus) nurturing behavior with food fondness was deliberate in Northern land of Odisha during February 2017 to December 2019.The foremost objective of the existing survey is to document the forage plant species intake by Asian elephants. Though the respective study area harbors a noble quantity of plant types, only 146 species were identified as fodder plants which have been consumed by elephants in this survey period. The food path of elephant was identified as branch flouting, bark flaking, twig infringement, flower tugging and stem twisting and uprooting in different regions of study area throughout altered seasons. Adaptation of principally browsing strategy with that of grazing around the year was related to seasonal variation of diet plants as per the availability. This survey elucidates that total 146 species of forest plants belongs to 55 Families and 19 species of non-forest plant belongs to 8 Families. The extensive consumable plant species by elephants i.e. Aegle marmelos (Bel), Careya arbore (Kumbhi), Bauhinia racemosa, Kydia calycina, Bauhinia vahli(Siali), Helicteres isora(Orola), Madhuca indica (Mahulo), Zizyphus mauritiona (BaraKoli), Artocarpus heterophyllus (Panasa), Shorea robust(Sal),Limonia acidissima (Kendu), Smilax zeylanica (Muturi) and Diosporea species. They were affectionate fruits of Mangifera indica and Artocarpus heterophyllus in summer, bamboo during rainy and Madhuca indica during winter. Minuscular analysis of elephant's dung showing an extraordinary variation in typical dicot-monocot proportion recommended that the food plant collection of elephant was extremely seasonal and unscrupulous.
