IUCN Red List vulnerable species (Animalia)

A "vulnerable" species on the IUCN Red List is one that faces a high risk of endangerment in the wild. This is a specific category used by the International Union for Conservation of Nature (IUCN) to assess the conservation status of animal species globally. The "Animalia" specification clarifies that this entry specifically focuses on animals.

The classification of a species as vulnerable is based on a number of criteria, including:

• Population size reduction: A significant decline in population size observed over a defined period (e.g., 10 years or three generations).
• Geographic range: A limited or fragmented geographic range, often coupled with continuing decline.
• Population size: A small population size, often combined with continuing decline or fluctuations.
• Quantitative analysis: Results from population viability analysis or other modeling that predicts a high probability of extinction in the wild within a specified timeframe (e.g., 100 years).

Species assessed as "vulnerable" are not yet considered "endangered" or "critically endangered" (the categories denoting higher risk), but they require focused conservation efforts to prevent their status from worsening. Conservation actions for vulnerable species can include habitat protection, anti-poaching measures, captive breeding programs, and sustainable resource management. Regular reassessment of vulnerable species is crucial to track their progress and adjust conservation strategies as needed. The IUCN Red List is a dynamic assessment, and species can be moved between categories as new data becomes available.
