Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or on an entire planet. Biodiversity is not consistent across the Earth. Western Ghats, older than the Himalayas, is one of the 34 global hotspots of biodiversityflora, fauna, landscape and ethnicity. Western Ghats, a narrow 1,700 km strip that stretches from the mouth of Tapti in Dhule district of Maharashtra to Kanyakumari in Tamil Nadu is nature's unique evolutionary laboratory still at work. We did a biodiversity survey for plant species in Karunya university Academic campus, which is located in the southern parts of the Western

The North Cachar Hills, now known as Dima Hasao is a southern district of Assam, India and is located between 24 0 58 / N and 25 0 47 / N latitudes and 92 0 27 / E and 93 0 43 / E longitudes. The main ethnic groups in the district are Dimasas, Zeme Nagas, Hmars, Hrangkhols, Biates, Jansens and Thadous (New-Kukis), Sakacheps (Khelmas), Vaipheis and Jaintia (Pnars).

The Indian Himalayan Region (IHR) is known as the repository of biodiversity. It supports 8,000 species of angiosperms. The orchidaceae is among the dominant family of angiospecies and highly evolved family among the monocotyledon. The species of this family are facing tremendous pressure due to habitat degradation, overexploitation and changing environmental conditions. Therefore, while exploring the floristic diversity of Parvati Valley, attempts have also been made to explore the orchid diversity and analyze for diversity, distribution patterns, nativity, endemism, threat categories and indigenous uses. Total 19 species of the orchids representing 13 genera were recorded between 1100-3600 m amsl. Of these, 13 species were natives, 6 species near endemic and 5 species non-natives. These species represented in grassland, shady moist, forests, alpine meadows, moist rocks and bouldary habitats. These species were used for curing various diseases/ailments by the inhabitants of the valley. Due to habitat degradation the populations of these species are decreasing fast. The over exploitation, habitat degradation and changing environmental conditions of these species has led rapid population depletion. Therefore, appropriate strategy has been suggested for the conservation and management of these orchids.

The indigenous plants of Ranapur reserve forest of Odisha state, India, possess ample scope in ethnobotany due to their medicinal properties. Keeping in view of the requirements of the urbanites, this work highlights the utilization of native flora, identification, ethnobotany, floristic survey, and preservation of natural and cultivated plant species within the hills of Ranapur, Odisha. A field study around the Ranapur forest resulted in a wide diversity accounting for 143 plant species belonging to 53 families, which were identified and documented alongside their botanical name, family, and habitat following local herbaria, archives of Flora of Orissa, monographs, and standard taxonomic study. Gmelina arborea, Rauwolfia serpentina, and Crataeva nurvala (Varuna) fall into the RET taxa (Rare, Endangered, and Threatened) and are groundbreaking against various diseases. A few wild plants such as Shorea robusta, Dalbergia sissoo, Pterocarpus marsupium, Murraya koenigii, and Schleichera...

The present study deals with new addition to the flora of the Great Himalayan National Park (GHNP), located in Kullu district of Himachal Pradesh. A total of 39 unreported species under 26 families were recorded during the recent plant exploration from the Great Himalayan National Park. A brief description based on the field character, phenology, a note on distribution and ecology has been provided here for each species. lkjka 'k iz Lrq r v/;;u fgekpy iz ns 'k ds dq Yyw tuin es a fLFkr xz s V fgeky;u jk"Vª h; m|ku ¼th,p,uih½ ds ouLifrtkr es a uohu la ;ks tuks a ij vk/kkfjr gS A xz s V fgeky;u jk"Vª h; m|ku es a gky es a fd;s x;s okuLifrd leUos "k.kks a ds nkS jku 26 dq yks a ls lEcfU/kr dq y 39 vlw phc) tkfr;ks a dks vfHkys f[kr fd;k x;k gS A iz R;s d tkfr dk fQYM y{k.k] Qyksfndh] forj.k ,oa ikfjfLFkfrdh ij vk/ kkfjr la f{kIr ofxZ dh fooj.k fn;k x;k gS A

Check List, 2012

In the present study, we provide a checklist of the vascular plants of Kinnaur district situated in the Himachal Pradesh state of India in the western Himalaya. This checklist includes 893 taxa (viz., species, subspecies and varieties) belonging to 881 species of angiosperms and gymnosperms distributed among 102 families and 433 genera, and 30 species of pteridophytes. Information about the growth habit, threat and endemicity status is also provided. Our results show that family Compositae is by far the most species rich family with 122 species, followed by Poaceae (69), Rosaceae (58), Leguminosae (49) and Lamiaceae (38). Among the genera, Artemisia is the most diverse genus with 19 species, followed by Potentilla (14), Saussurea (13), Polygonum (11), Astragalus (10), Lonicera (10) and Nepeta (10). Similar to other regions in the western Himalayan range, family-to-genera ratio was 1:4.25 and the genera-to-species ratio was 1:2.04. Out of 893 taxa, our checklist includes 606 herb spe...

The North Cachar Hills, now known as Dima Hasao is a southern district of Assam, India and is located between 24 0 58 / N and 25 0 47 / N latitudes and 92 0 27 / E and 93 0 43 / E longitudes. The main ethnic groups in the district are Dimasas, Zeme Nagas, Hmars, Hrangkhols, Biates, Jansens and Thadous (New-Kukis), Sakacheps (Khelmas), Vaipheis and Jaintia (Pnars). The paper provides a comprehensive account of 114 wild species of plants those are either cultivated or protected in the homestead gardens and/or in the vicinity of villages by the ethnic people for their use. The present study records the use of 111 species belonging 87 genera and 45 families. Out of these plants, 59 species have been used in more than one way. Out of the total recorded 77 edible plants, 21 plants are used both as food and/or medicine. It is also observed that most of the semi-domesticated and protected plants have multiferous uses among the ethnic groups.

The Sirumalai hills, situated in the southern most part of the Eastern Ghats in Tamil Nadu are known for their rich biodiversity for their close location to the Kodaikanal hills of the Western Ghats. They lie in Dindigul district, between 10 0 00-10 0 30N & 77 0 33-78 0 15E and at altitudes ranging from 400 to 1650 m. The lower hill ranges consist of highly disturbed scrub forests while tropical dry deciduous forests occupy the major portion of middle hill ranges. Semi-evergreen forests occur in the higher elevations and along valleys. Woodland savannahs are found along slopes. Bestowed with several endemic and medicinal plants, these hill ranges are facing severe threats owing to the growing anthropogenic disturbances and increasing coffee estates, rubber plantations, orchards and cultivation of several vegetable crops.
