See: List of endangered plants, List of critically endangered plants. Vulnerable, Endangered, and Critically Endangered species are collectively referred to as threatened species by the IUCN. Additionally 1674 plant species (7.6% of those evaluated) are listed as Data Deficient , meaning there is insufficient information for a full assessment ...
Plant defense against herbivory or host-plant resistance is a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores. Many plants produce secondary metabolites , known as allelochemicals , that influence the behavior, growth, or survival of herbivores.
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The World's 100 most threatened species [1] is a compilation of the most threatened animals, plants, and fungi in the world. It was the result of a collaboration between over 8,000 scientists from the International Union for Conservation of Nature Species Survival Commission (IUCN SSC), along with the Zoological Society of London .

In September 2016, the International Union for Conservation of Nature (IUCN) listed 3654 endangered plant species. [1] Of all evaluated plant species, 17% are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN.
There are about 29,015 species of plants including 17,926 species of flowering plants. This is about 9.1% of the total plant species identified worldwide and 6,842 species are endemic to India. Other plant species include 7,244 algae, 2,504 bryophytes, 1,267 pteridophytes and 74 gymnosperms. [3]
