Invasive alien species can outcompete native flora, especially those that are already endangered. Therefore, strict monitoring and control of such species are vital for the success of conservation efforts within protected areas.

The IUCN Red List is the globally recognized standard for assessing the conservation status of species, including plants, and its criteria are used to identify critically endangered flora.

The recent declarations of new protected areas are specifically targeted at conserving plant species that are on the brink of extinction, i.e., critically endangered flora.

Pollution from industrial and agricultural runoff, along with accidental bycatch in fishing gear, are consistently identified as the most significant threats to the survival of the Ganges River Dolphin.

The Ganges River Dolphin was declared the National Aquatic Animal of India in 2009, recognizing its ecological importance and the need for its conservation.

Recent surveys up to 2026 indicate that the population of the Ganges River Dolphin has remained stable or shown a slight increase in many surveyed areas, suggesting that conservation efforts are having a positive impact.
