Population viability is a field of research that focuses on assessing the likelihood of a population's continued existence in the face of various threats, such as habitat destruction, climate change, disease, and hunting. Researchers in this field use mathematical models, field surveys, and genetic analysis to predict how populations may change over time and to identify potential conservation strategies to ensure their long-term survival. By understanding the factors that contribute to population decline or extinction, researchers can work towards promoting the resilience and stability of wildlife and plant populations.
