Which of the following is the oldest Biosphere Reserve of India?

Question

Accepted Answer

The correct option is 1: Nilgiri

The Nilgiri Biosphere Reserve is correctly identified as the oldest Biosphere Reserve of India, having been established in **1986**. This monumental designation marked the beginning of India’s national program to conserve genetic resources, ecosystems, and species diversity through the internationally recognized model of biosphere reserves. Located at the tri-junction of Tamil Nadu, Kerala, and Karnataka, the Nilgiri Biosphere Reserve encompasses a vast area of 5,520 square kilometers within the Western Ghats, which is a recognized global biodiversity hotspot. Its ecosystems range from tropical wet evergreen forests to montane sholas and grasslands. The reserve is critical for the conservation of species like the Nilgiri Tahr, Nilgiri Langur, and Lion-tailed Macaque, and it links several key protected areas like Mudumalai, Bandipur, and Silent Valley National Parks, cementing its historical and ecological importance as the nation’s first and foremost reserve.

The incorrect option is 2: Panna

Panna is a much newer addition to India's network of Biosphere Reserves. It was notified by the Government of India much later, in **2011**, and was officially included in UNESCO's World Network of Biosphere Reserves even more recently, in 2020. The Panna Biosphere Reserve is located in the Vindhyan Hills of Madhya Pradesh and is famous as a critical habitat for the Bengal Tiger (Panna Tiger Reserve). While ecologically significant, its establishment date places it chronologically well after the Nilgiri reserve.

The incorrect option is 3: Nanda Devi

The Nanda Devi Biosphere Reserve, situated in the high-altitude Western Himalayas of Uttarakhand, was established by the Government of India in **1988**. Although it is one of the earliest reserves to be designated, its establishment came two years *after* the Nilgiri Biosphere Reserve. The Nanda Devi reserve is characterized by its extremely rugged mountain terrain and includes the magnificent Nanda Devi peak, which is the second highest mountain in India. It is a critical area for conserving unique Himalayan flora and fauna, but chronologically, it is not the oldest.

The incorrect option is 4: Simplipal

The Similipal Biosphere Reserve (often mistakenly spelled Simplipal) is located in the Mayurbhanj district of Odisha. This reserve was designated by the Government of India in **1994**. Known for its extensive moist deciduous forests, waterfalls, and as a major Tiger Reserve, Similipal is a vital conservation area in Eastern India. However, its establishment year of 1994 is nearly a decade later than Nilgiri's 1986 designation, making it clearly not the oldest of the options provided.
