Knowing about keystone species is significant because these organisms have a disproportionately large impact on their ecosystems, often determining the structure and health of community dynamics. The removal or decline of a keystone species can lead to dramatic changes, causing shifts in population sizes and the loss of biodiversity. Understanding their roles helps conservationists prioritize protective measures, ensuring the stability and resilience of entire ecosystems. Additionally, keystone species can serve as indicators of environmental health, guiding management decisions in restoration and conservation efforts.
