59 plant species in IUCN threat categories

Threatened wildlife is not just about tigers but numerous plants too. Recently, scientists identified the threat status of 59 Indian plant species based on criteria used by the International Union for Conservation of Nature (IUCN), in the hope that this “streamlines” conservation efforts for the plants.

Around 2,700 plant species in India are at risk but very few have been assessed by the IUCN. To bridge this gap, experts from several institutes prioritized 59 plant species that are at risk of “elimination” if the threat levels they face are not assessed soon. They assigned each species a threat status based on IUCN criteria.

This included the extent and area of each plant’s geographical range, which revealed that 10 species are critically endangered, 18 endangered, six vulnerable, five near threatened and one species each are data deficient and least concern.

Causes for the decline in population:

Based on population sizes and numbers of mature individuals remaining in the wild (using field surveys that also revealed that habitat loss was a huge factor affecting many declining plant populations), the team classified 10 species as critically endangered, three as endangered and five as vulnerable. Germination tests in the laboratory also suggest that factors such as low seed viability could have caused declines in the wild too.

Quantifying threat levels of species can be crucial for their conservation. For instance, funding agencies often consider the threat status of species provided in IUCN’s Red List (a catalog of the world’s threatened species), to sponsor research and conservation activities to save them.

IUCN- key facts:

IUCN was founded in  October 1948 as the International Union for the Protection of Nature (or IUPN) following an international conference in Fontainebleau, France.

It was renamed as International Union for Conservation of Nature and Natural Resources in 1956 with the acronym IUCN.

IUCN is the world’s first global environmental organization. Today it is the largest professional global conservation network

The Union’s HQ is located in Gland, near Geneva, in Switzerland.

It demonstrates how biodiversity is fundamental to addressing some of the world’s greatest challenges such as climate change, sustainable development, and food security.

The IUCN Red List is set upon precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. The aim is to convey the urgency of conservation issues to the public and policymakers, as well as help the international community to try to reduce species extinction.

Species are classified by the IUCN Red List into nine groups, set through criteria such as rate of decline, population size, the area of geographic distribution, and degree of population and distribution fragmentation.
