    It is important to understand the tree species composition, abundance, species diversity and stratification in tropical dry deciduous forests that are under threat. A quadrat study was attempted in the dry deciduous forests along the ecological gradients in the Godavari Valley of northern Telangana, India. The study records the presence of 110 flowering plant taxa belonging to 82 genera and 37 families in 120 sampled plots, and there was enumeration of 15,192 individuals of ≥10 cm girth at breast height. Tectona grandis (teak) is the principal forest cover component in the region, which often formed pure stands in Adilabad and, to some extent, in Nizamabad districts. Further down to the Warangal district, teak was gradually replaced by Terminalia alata. Twenty tree species were found dominant at one place to the other, and the top 10 dominant taxa have shared nearly 41% of the total density of the forest cover. The tree relative density ranged from 0.007% to 20.84%. The values of Importance Value Index were between 0.245 (12 spp. including some exotics) and 32.6 (teak). These baseline data help to know the change detection along the gradients in the tropical forest ecosystem of a major river valley in the region and the drivers of change

    The article describes cane-cum-bat roost site at Palampet (Warangal District, Andhra Pradesh, India). Although notified as a cane reserve by the state government, it is not spared off the usual habitat depletion and destruction. The functional pyramid formed of Calamus-Terminalia-Pteropus is reported here as first of its kind. This article also places on record seven more cane sites besides noting the importance of the ecology of Morancha Vagu and stressing the need for preserving its banks by planting Calamus rotang L. Ecological education to the local people about biodiversity value and conservation at all levels of its organization is called for

    On the identity and occurrence of <i>Ophioglossum costatum</i> (Pteridophyta: Ophioglossaceae) in Andhra Pradesh, India

    Ophioglossum costatum (Ophioglossaceae) was collected for the first time from Telangana region and reported it as an addition to the fern flora of Andhra Pradesh, India. Ophioglossum costatum is a widespread pantropical species though not collected often owing to its distribution in small, undisturbed specific habitats, ephemeral nature (seasonality: monsoonal appearance) and misidentification with O. nudicaule in the herbarium (dugout and mounted specimens). The study stresses the significance of field characters for the correct identification of these rhizomatous geophytic cryptogams and brings out the differences between Ophioglossum costatum and O. nudicaule

    Plant wealth of a sacred grove: Mallur Gutta, Telangana state, India

    Sateesh Suthari,1 Ramesh Kandagalta,2 Ajmeera Ragan,2 Vatsavaya S Raju,2 1Department of Plant Sciences, School of Life Sciences, University of Hyderabad, Hyderabad, 2Plant Systematics Laboratory, Department of Botany, Kakatiya University, Warangal, India Abstract: The Mallur Gutta (Hill) of Warangal district in Telangana state, India, reputed as a habitat for medicinal plants, was inventoried from 2009 to 2015 for its plant wealth through the traditional knowledge of the local people. The Hindu temples of Lord Sri Laxminarasimha Swamy and Lord Hanuman, and the ethnic worship of mahua trees indicated it was a sacred grove which was selected as a Medicinal Plants Conservation Area. The exploration of Mallur Gutta resulted in the enumeration and documentation of plant wealth representing 470 species of 318 genera pertaining to 95 families of vascular plants. The importance of the grove as the residence for many rare or medicinal species in the state of Telangana is documented. The plant diversity is analyzed in terms of growth and life forms which indicate the prevailing microclimate, ecological opportunities and the species richness. The ecological services rendered by the Mallur Gutta forest ecosystem are documented to study how the great majority of the species are used by the ethnic and nonethnic people, and also the pilgrims who visit the shrine for its serenity. The study also identified two major threats to the conservation of hill ecosystem and the archeological site: 1) biotic pressure (the ever-increasing pilgrims, grazing by cattle, goat and sheep, the development activities taken up for the pilgrims, nondegradable litter thrown, collection of medicinal plants and widening of the pathway to the Chintamani perennial stream&nbsp;&ndash; the trampling and alien plant invasions of the marsh sustaining the stream); and 2) the potential for fire spreading from burning the litter. The study suggests the need to initiate remedial measures toward ecosystem recovery through fencing the natural vegetation, maintaining a fire line, and restricting the movement of people and domesticated animals on the hill top.

    Ethnobotanical Knowledge Studied in Pocharam Wildlife Sanctuary, Telangana, India

    <p class="Continutabstract">A survey was conducted in 31 fringe villages of Pocharam wildlife sanctuary, Telangana, India, during 2010 to 2012, in order to explore and document the ethnobotanical knowledge of Yerukulas and Lambadis communities. There was revealed the use of 173 Angiosperm species. The pattern of the plant use as per habitat (terrestrial/aquatic), habit (growth form), plant part (organ) and taxonomic category (families), nativity and occurrence (wild/cultivated) were established. Dicots contribute more than Monocots to the medicinal and ethnobotanical use. This might be due to the species strength in the region. When the plant use-data were analyzed, trees contributed with 68 uses, followed by herbs (51), climbers (32) and shrubs (22). Perhaps this was a reflection of the floristic composition and the prevailing <em>Phanero-therophytic</em> climate. Out of the 173 plant taxa that were noted as being utilized by the ethnic people in the sanctuary, the greatest number (154; 89.1%) were indigenous and wild. The introduced species were the crops under cultivation and planted. Although the local people use plants for various purposes, they largely serve medicinal scopes (83.24%) and for subsistence (21.96%).</p

    Intrusion of devil weed Chromolaena odorata, an exotic invasive, into Kinnerasani and Eturnagaram wildlife sanctuaries, Telangana, India

    The spread of devil weed is alarming in areas of podu cultivation, on the bunds of agricultural lands, wastelands, along roadsides, tracks, forest gaps, protected areas and plantations in the two said wildlife sanctuaries. It is found invading new territories easily along the river banks and steadily destroying the riparian elements. The manual removal of this weed (mechanical method) before flowering is the effective means to mitigate the spread of the species in comparison to the biological (Pareuchaetes pseudoinsulata, P. insulata, Actinote thalia-pyrrha) and chemical (Glyphosate, Triclopyrester) methods attempted. It is not trouble in its native habitat but is weedy in India for want of natural enemies to keep it under control. It is a mandate to prevent the loss of native biodiversity due to biological invasions. Conversely, there is an urgent need to devise action plans by managers of the respective wildlife sanctuaries to control and eradicate it. The local people are to be educated of its potential dangers to their farming on one hand and NTFP extraction from the local forests on the other. The Government of India has to develop a national level policy towards the control of invasive alien weeds in general and implement it at the earliest before we loose our indigenous biodiversity once for all
