JNU Campus
Location
Jawaharlal Nehru University (JNU), established in 1969 is situated in the south-central ridge of Delhi, a natural green belt that significantly mitigates air pollution in the city. The campus, known for its well-preserved ridge ecosystems, is home to a wide variety of flora and fauna native to the Delhi region. Covering approximately 1019.38 acres, with 5,22,688.45 square meters designated as green areas, JNU is located at 77°9'52.24" E longitude and 28°32'15.42" N latitude. The university is perched on the Aravalli Hill range, which extends to Gujarat.
Climate
The climate of JNU is semi-arid, characterized by extreme seasonal variations. Summers can be harsh, with temperatures rising up to 46ºC in June, while winters are cold, with January being the coldest month. The monsoon season, lasting from July to August, contributes to an average annual rainfall of 66.6 cm.
Geology and Soil
The geology of the JNU campus is dominated by quartzite rocks, ranging from fine to coarse-grained, and displaying colors like grey and brick red. The soil is categorized as colluvial deposit, which is predominantly dry, sandy, and rocky, with minimal humus content. This results in sparse vegetation across the area. The campus is part of the tropical thorn forest type, as classified by Champion and Seth in 1968, and is rich in diverse species of trees, shrubs, and herbs.
Purpose and Significance of the Database
This plant diversity database is a vital tool for understanding the ecosystems within the JNU campus. It aids in monitoring ecological changes over time, identifying rare and threatened species, detecting invasive species, managing pests, and documenting medicinal plants. The database also informs conservation and management programs, playing a crucial role in biodiversity conservation and sustainable development. Notably, this is the first comprehensive plant survey and documentation effort undertaken for the JNU campus.
