INDIA: Valley Of Flowers National Park

Valley of Flowers National Park is an Indian national park, located in West Himalaya, in the state of Uttarakhand and is known for its meadows of endemic alpine flowers and the variety of flora. This richly diverse area is also home to rare and endangered animals, including the Asiatic black bear,snow leopard,musk deer,brown bear, red fox, and blue sheep.

Birds found in the park include Himalayan monal pheasant and other high altitude birds.At 3352 to 3658 meters above sea level, the gentle landscape of the Valley of Flowers National Park complements the rugged mountain wilderness of Nanda Devi National Park to the east.

Together, they encompass a unique transition zone between the mountain ranges of the Zanskar and Great Himalaya. The park stretches over an expanse of 87.50 km2 and it is about 8 km long and 2 km wide.Both parks are encompassed in the Nanda Devi Biosphere Reserve (223,674 ha) which is further surrounded by a buffer zone (5,148.57 km2). This Reserve is in the UNESCO World Network of Biosphere Reserves since 2004.

The Valley of Flowers is a high-altitude Himalayan valley that has long been acknowledged by renowned mountaineers, botanists, and in literature. It has been recognized internationally for over a century and is referenced in the Hindu religion. Local people have visited the valley since ancient times.

Indian yogis (Yogesh Mota) are known to have visited the valley for meditation.The Valley of Flowers has many different colourful flowers, taking on various shades of colours as time progressed.The valley was declared a national park in 1982 and now it is a World Heritage Site.

The Valley of Flowers has gained importance as a region containing a diversity of alpine flora, representative of the Western Himalayan alpine shrub and meadows ecoregion. The rich diversity of species reflects the valley's location within a transition zone between the Zanskar and Great Himalayas ranges to the north and south, respectively, and between the Eastern Himalaya and Western Himalaya flora.

A number of plant species are considered threatened. Several have not been recorded outside of Uttarakhand. Two have not been recorded in Nanda Devi National Park. The diversity of threatened species of medicinal plants is higher than has been recorded in other Indian Himalayan protected areas.

The entire Nanda Devi Biosphere Reserve lies within the Western Himalayas Endemic Bird Area (EBA). The Valley of Flowers National Park is the second core zone of the Nanda Devi Biosphere Reserve. Seven restricted-range bird species are endemic to this part of the EBA.

The Valley of Flowers is nestled in the upper expanses of Bhyundar Ganga near Joshimath in Garhwal region. The lower reaches of Bhyundar Ganga near Gobindghat are known as Bhyundar Valley. The Valley of Flowers is in the Pushpawati valley 23 km north-northwest of Nanda Devi Park, It lies between 30° 41' to 30° 48'N and 79° 33' to 79° 46'E.

The Valley is 20 km northwest of Nanda Devi National Park across the wide valley of the Bhyundar Ganga. It is one of two hanging valleys lying at the head of the Bhyundar valley,the other being the shorter Hemkund valley which runs parallel some 10 km south. It runs east-west approximately 15 km by an average of 6 km wide, in the basin of the Pushpawati river, a small tributary flowing from the Tipra glacier which descends from Gauri Parbat in the east.

The area lies on the Zanskar range of the Himalayas with the highest point in the national park being Gauri parbat at 6,719 m above sea level.

1862: The Pushpawati valley was discovered by Col. Edmund Smyth;

1931: The valley visited by the climber Frank S. Smythe who wrote a book publicising the "Valley of Flowers";

1939: The basin established as the Nanda Devi Game Sanctuary by Government Order 1493/XIV- 28 of 7/01;

1962: Border disputes closed the area to traffic, altering the local economy;

1974-82: The sanctuary was opened to mountaineering, but the ensuing degradation led to its closure to all users;

1980: The park was established as Sanjay Gandhi National Park by Notification 3912/ XIV 3-35-80; grazing and mountaineering stopped;

1980: The Valley of Flowers was declared a national park by Government Order 4278/XIV-3-66-80 under the provisions of the Wildlife Protection Act of 1972, for the conservation of its flora;

1982: The park was renamed Nanda Devi National Park;

1988: The Nanda Devi National Biosphere Reserve established (223,674 ha) with the national park as core zone (62,462 ha) and a 514,857 ha buffer area surrounding both sites; restrictions were imposed on the rights of nearby villagers;

2000: The Biosphere Reserve extended by the government to 586,069 ha and the Valley of Flowers National Park was added as the second core zone (62,462 ha+ 8,750 ha, totalling core areas of 71,212 ha);

2004: The two core zones and buffer zone designated a UNESCO MAB reserve.

The park is administered by the Uttarakhand State Forestry Department, the national Ministry of Environment and Forests, India. There is no settlement in the national park and grazing in the area has been banned since 1983. The park is open only during summer from June to October and it is covered by heavy snow for the rest of the year.

Being an inner Himalayan valley, the Nanda Devi Basin has a distinctive microclimate. Conditions are generally dry with low annual precipitation, but there is heavy monsoon rainfall from late June to early September. Prevailing mist and low cloud during the monsoon keeps the soil moist, hence the vegetation is lusher than is usual in the drier inner Himalayan valleys.

From mid April to June temperatures are moderate to cool (19 °C maximum). The Valley of Flowers also has the microclimate of an enclosed inner Himalayan valley, and is shielded from the full impact of the southwest summer monsoon by the Greater Himalaya range to its south. There is often dense fog and rain especially during the late summer monsoon.

Both Basin and Valley are usually snow-bound for six to seven months between late October and late March, the snow accumulating deeper and at lower altitudes on the shadowed southern than on the northern side of the valleys.

Getting to the Valley of Flowers requires a trek of about 17 km (10.5 mi). The nearest major town is Joshimath in Garhwal, which has convenient road connections from Haridwar and Dehradun, both about 270 km (168 mi) from Joshimath. From Delhi, one can take the train to Haridwar and then travel by bus to Govindghat via Rishikesh.Govindghat is approximately 24 km before another important destination of Badrinath. It is also possible to drive from Delhi to Govindghat, a distance of about 500 km.

Govindghat is a small place close to Joshimath (around one hour distance), where the trek begins. From Gobindghat, shared taxis up to 4 km and then a trek of less than 11 km (8.6 mi) brings trekkers to Ghangaria, a small settlement located about 3 km (about 2 mi) from the valley. One can also hire a porter, mule or helicopter to reach Ghangaria.

The trek from Gobindghat to Ghangaria is common to the Sikh Temple at Hemkund and a trekker is likely to find many Sikh pilgrims on the route.As one nears Ghangaria one is greeted by fields of perfumed wild flowers, wild rose bushes and wild strawberries by the sides of the path. The visitors to Valley of Flowers need to get a permit from Forest Department, at Ghangaria and the permit is valid for three days and visiting and trekking is allowed only during day time.

As visitors are not allowed to stay inside the National park, accommodation can be obtained at Gangaria.Best time to visit is between late July and early September, when the valley is full of flowers, just after the outbreak of monsoon.

The valley has three sub-alpine between 3,200m and 3,500m which is the limit for trees, lower alpine between 3,500m and 3,700m, and higher alpine above 3,700m. The habitats include valley bottom, river bed, small forests, meadows, eroded, scrubby and stable slopes, moraine, plateau, bogs, stone desert and caves. The lower surrounding hills in the buffer zone are thickly forested.

The Forest Research Institute in 1992 recorded 600 species of angiosperms and 30 pteridophytes in the valley and surroundings, discovering 58 new records for the valley of which 4 were new for Himalayan state. Of these plants, 5 out of 6 species globally threatened are not found in Nanda Devi National Park or elsewhere in Uttarakhand: Aconitum falconeri, A. balfouri, Himalayan maple (Acer caesium), the blue Himalayan poppy (Meconopsis aculeata) and Saussurea atkinsoni.

Kala classified 31 species of rare and endangered categories within the national park in 1998. Further his studies report that the dominant family in Valley of Flowers is Asteraceae with 62 species.45 medicinal plants are used by local villagers and several species, such as Saussurea obvallata (brahmakamal) are collected as religious offerings to goddesses Nanda Devi and Sunanda Devi.The site is designated a Centre of Plant Diversity.

Characteristic of the sub-alpine zone are high altitude forests which help to retain moisture and snow and support a large number of floral and faunal communities. It is dominated by the uncommon Himalayan maple Acer caesium (VU), west Himalayan fir Abies pindrow, Himalayan white birch Betula utilis, and Rhododendron campanulatum with Himalayan yew Taxus wallichiana, Syringa emodi and Sorbus lanata.

Some of the common herbs are Arisaema jacquemontii, Boschniakia himalaica, Corydalis cashmeriana, Polemonium caerulium, Polygonum polystachyum (a rampant tall weed), Impatiens sulcata, Geranium wallichianum, Galium aparine, Morina longifolia, Inula grandiflora, Nomochoris oxypetala, Anemone rivularis, Pedicularis pectinata, P. bicornuta, Primula denticulate and Trillidium govanianum.In trampled areas where past livestock congregated, Himalayan knotweed Polygonum polystachium is a rampant weed.

The density of wild animals in the valley is not high, but all the animals found are rare or endangered. A total 13 species of mammals are recorded for the park by CP Kala and its vicinity although only he sighted 9 species directly: northern plains grey langur Semnopithecus entellus, flying squirrel Petaurista petaurista, Himalayan black bear Ursus thibetanus (VU), red fox Vulpes vulpes, Himalayan weasel Mustela sibirica, and Himalayan yellow-throated marten Martes flavigula, Himalayan goral Naemorhedus goral, Himalayan musk deer Moschus leucogaster, Indian chevrotain Moschiola indica, Himalayan thar Hemitragus jemlahicus (VU) and serow Capricornis sumatraensis (VU).

The tahr is common, the serow, goral, musk deer and bharal, blue sheep are rare.The common leopard Panthera pardus is reported from lower parts of the valley closer to the villages. Local people have also reported evidence of brown bear Ursus arctos and bharal or blue sheep Pseudois nayaur. A recent faunal survey in October 2004 has established the presence of snow leopard Panthera uncia (EN) in the national park.

The area is within the West Himalayan Endemic Bird Area but there have been no surveys specific to the Valley. 114 species were seen in 1993 in Nanda Devi Park.

Species frequently seen in the valley include lammergeier Gypaetus barbatus, Himalayan vulture Gyps himalayensis, yellow billed and red billed choughs Pyrrhocorax graculus and P. pyrrhocorax, koklass pheasant Pucrasia macrolopha, the nationally listed Himalayan monal pheasant Lophophorus impejanus, found in rhododendron thickets, scaly-bellied and yellow-nape woodpeckers Picus squamatus and P. flavinucha, great and bluethroated barbets Megalaima virens and M. asiatica, snow pigeon Columba leuconota and spotted dove Stigmatopelia chinensis.

The area is relatively poor in reptiles: most often seen are the high altitude lizard Agama tuberculata, Himalayan ground skink Leiolopisma himalayana and Himalayan pit viper Gloydius himalayanus. Along with the flowers are wild bees and many species of butterfly which need to be more researched.

A few of the more evident species are lime butterfly Papilio demoleus demoleus, common yellow swallowtail Papilio machaon, common Mormon Papilio polytes romulus, spangle Papilio protenor protenor and common blue apollo Parnassius hardwickei.

The flora was surveyed and inventoried in 1987 by the Botanical Survey of India, in 1992 by the Forest Research Institute and in 1997 by the Wildlife Institute of India which found five species new to science. A research nursery and seed/rhizome/tuber bank for propagating rare plants and valuable medicinal herbs has been created at Musadhar near the entrance of the site.

Rare and valuable medicinal plants are the subject of special programs. These include Aconitum heterophyllum, A. falconeri, Arnebia benthamii, Dactylorhiza hatagirea, Gymnadenia orchides, Megacarpaea polyandra, Picrorhiza kurrooa, Podophyllum haxandrum and Taxus wallichiana.

Research plots have been set up to determine the best way to control the spread of the tall Himalayan knotweed Polygonum polystachium without damaging other plants or the surface of the soil. A first annual survey was conducted in 2004 and will be repeated annually.

Flowers mostly orchids, poppies, primulas, marigold, daisies and anemones carpet the ground.Sub-alpine forests of birch and rhododendron cover parts of the park's area. A decade long study of Prof. C.P. Kala from 1993 onwards concludes that the Valley of Flowers endows with 520 species of higher plants (angiosperms, gymnosperms and pteridophytes), of these 498 are flowering plants.

The park has many species of medicinal plants including Dactylorhiza hatagirea, Picrorhiza kurrooa, Aconitum violaceum, Polygonatum multiflorum, Fritillaria roylei and Podophyllum hexandrum.
