Rare Endangered Threatened (RET) species Garden

An endangered species is a native species that faces a significant risk of extinction in the near future throughout all or a significant portion of its range. Such species may be declining in number due to threats such as habitat destruction, climate change, or pressure from invasive species. Approximately one fourth of all plant species in the world are at risk of being endangered or going extinct. The combination of global warming and habitat destruction is the sole reason for the disappearance of many plants. Though there are thousands of interesting and unusual plants, here are some common plants which have become rare and endangered species in the past 30 years due to habitat destruction.

The flora of India is one of the richest in the world due to the country’s wide range of climate, topology, and environment. There are over 15,000 species of flowering plants in India which account for 6% of all plant species in the world. Many plant species are being destroyed, however, due to their prevalent removal. Plants seemed to be the most threatened with 60 species being listed as Critically Endangered and 141 as Endangered in IUCN Red Data list.

AS part of conservation among Gymnosperms and Angioperms assembled in the Garden there are 10 and 14 species, respectively which belong to different IUCN categories. There are 10 species belonging to Gymnosperms and 18 species of Angioperms which belong to Least Concern category of IUCN.

Ten plants each of Saraca indica and Commiphora wightii, and Commiphora mukul, designated as rare and endangered category have been planted in the RET Garden. Efforts will be made to increase their population from different areas to increase genetic diversity and clonally multiply them for field planting.
