Arunachal Pradesh, nestled in the Eastern Himalayas, is a treasure trove of biodiversity. Its varied topography, ranging from the snow-capped peaks to the subtropical lowlands, supports a rich tapestry of flora and fauna. The state is aptly nicknamed "The Orchid State of India" and "Paradise of the Botanists" for its astonishing array of plant life.
Vegetation of Arunachal Pradesh
The vegetation of Arunachal Pradesh is as diverse as its landscape. It can be broadly classified into five major categories:
Tropical Forests: Found in the foothills and lower elevations, these forests are characterized by evergreen and semi-evergreen trees, with a dense undergrowth of shrubs, herbs, and climbers. Common species include Dipterocarpus, Terminalia, Shorea, and bamboos.
Subtropical Forests: Occurring at elevations between 1000 and 2000 meters, these forests are dominated by broad-leaved evergreen trees like oaks, chestnuts, and magnolias.
Temperate Forests: Found at elevations between 2000 and 3500 meters, these forests feature a mix of coniferous and broad-leaved trees. Common conifers include pine, fir, and spruce, while broad-leaved species include rhododendrons, maples, and birches.
Sub-alpine and Alpine Forests: Occurring at elevations above 3500 meters, these forests are characterized by stunted trees, shrubs, and meadows. Rhododendrons, junipers, and willows are common species.
Alpine Meadows: Found above the tree line, these meadows are dominated by grasses, herbs, and dwarf shrubs.
The state is also home to several medicinal plants, orchids, and rare and endangered species like the Yew tree and the Blue Vanda.
Forest Cover of Arunachal Pradesh
Arunachal Pradesh boasts a significant forest cover, which plays a crucial role in maintaining ecological balance, conserving biodiversity, and providing livelihood to local communities.
According to the India State of Forest Report 2021, the forest cover in Arunachal Pradesh is estimated at 66,430.67 sq km, which is approximately 79.33% of the state's geographical area. This makes Arunachal Pradesh the second most forested state in India, after Madhya Pradesh.
The forest cover is categorized into:
Very Dense Forest: 21,058.37 sq km (25.15% of the geographical area)
Moderately Dense Forest: 30,175.56 sq km (36.03%)
Open Forest: 15,196.74 sq km (18.15%)
Despite its rich forest cover, Arunachal Pradesh faces challenges like deforestation, illegal logging, and shifting cultivation. Conservation efforts are underway to protect the state's forests and their biodiversity.
