Abstract

Maximum number of Pteridophytic diversity observed in Himalayan region and most Protected Areas of the Indian Himalayan Region have not received much attention in terms of floristic exploration. In Mehao Wildlife Sanctuary (MWLS) comprehensive studies on diversity, distribution pattern, habitat preference, rarity and conservation status of the Petridophytes have been carried and 205 species of Pteridophytes were recorded. The altitudinal distribution of the species revealed that the maximum numbers of species were present in the subtropical to temperate zone (900-3500m) and a decrease in diversity was noticed with increasing altitude. Terrestrial habitats showed maximum species richness and twenty one pteridophytic species had been identified as rare-endangered.

Abstract

Vegetation was analyzed quantitatively in miscellaneous open, miscellaneous closed, sal open and sal closed forests of West Chhindwara Forest Division (Madhya Pradesh). Total density for tree layer ranged between tree ha^-1 1,650 (miscellaneous open) to 3,030 t ha^-1 (sal closed); 4,960.23 (miscellaneous open) to 10,840 (sal closed) for shrubs and 3,180 (miscellaneous closed) to 3,18,000 (miscellaneous closed) plant ha^-1 for herb layer, whereas the range for dominance (cm² ha^-1) was 1,65,855 (miscellaneous closed) to 16,38,325 (sal closed) for trees; 5428 (miscellaneous open) to 16,100 (sal closed) for shrubs and 14,778 (miscellaneous open) to 11,28,020 (sal open) for herbs. It is very interesting to note that density and dominance of trees are invariably higher in closed forests, whereas, shrubs and herbs are higher in open forests except shrubs for miscellaneous closed forest. Miscellaneous open forest showed highest species richness followed by miscellaneous closed, sal closed and sal open for tree species. Diversity index values were highest for miscellaneous open followed by miscellaneous closed, sal open and sal closed. Miscellaneous open also showed highest species richness values, while sal open and closed miscellaneous showed lowest values, respectively, for shrub and herb species. Sal open and sal closed showed lowest values, respectively, for shrub and herb species for diversity index. Invariably, concentration of dominance followed the reverse trend to species diversity. Miscellaneous open and miscellaneous closed were more similar sites for tree and shrub species, whereas sal open and closed showed more similarity while considering herbs as the measure. Miscellaneous closed and sal open were most dissimilar sites for trees and shrubs and miscellaneous and sal closed for herb species. Examination of disturbance magnitude indicated that openness of the stand does not disturb the regeneration and stand development in terms of total tree composition in miscellaneous forest, whereas, it disturb the composition of Shorea robusta in case of open sal stand in ecotone.

Abstract

Pteridophytes form the dominant part of ground vegetation during rainy season. Total number of 14 families, 19 genera and 30 species of pteridophytes have been reported on the basis of published literature, herbarium consultation (BSA) and collections made by the author (Shweta Singh) from the area under report. The dominant families are Thelypteridaceae (6 Species) and Polypodiaceae (3 Species) respectively. Sanjay National Park consists of dense moist deciduous Sal forest. Madhuca and Diospyros species are also abundantly found in the Park. Dryopteris cochleata (Buch.-Ham. ex D. Don) C. Chr. occurs as common fern in the park. The species of Adiantum L., Selaginella P. Beauv., Tectaria Cav., and Dryopteris Adanson are medicinally used by local people in the area.

Abstract

The Saharias and Bhil-Mina tribal communities living in Vidisha district of Madhaya Pradesh mostly depend on the forests for medicine, food and fiber. Ethnobotanical exploration of Gyarsspur Tehsil of Vidisha has received little attention. This paper deals with an ethnobotanical information of 58 plants collected fiom tribal dominating area.

Abstract

Total 81 weeds belonging to 59 genera and 31 families growing in the University botanic garden at Sagar were found medicinally important. Various parts of all the weeds have been analyzed for their medicinal utility. Out of 81 weeds, leaves of 64 plants are found useful for various disorders. This is followed by ischolar_main of 25 plants which are medicinally important. Disease wise analysis has also been carried out. Analysis reveals that for cut, wounds, boils and burns about 29 weed plants are used, whereas 21 weed species each are used for asthma and skin diseases.
