What technique is frequently used by rangers to monitor wildlife populations?

Wildlife cameras are a widely used technique among park rangers to monitor wildlife populations because they allow for remote and continuous observation of animals in their natural habitats. These cameras capture images or videos of wildlife at different times of day and night without human presence, reducing the chances of disturbing the animals. They can be strategically placed in areas where animals are known to frequent, providing valuable data on species presence, behavior, and population sizes over extended periods.

This method is particularly advantageous in large or inaccessible areas where direct observation may be challenging. It also enables rangers to gather information on elusive or nocturnal species that are difficult to study through other means. By analyzing the footage or images recorded, rangers can gain insights into animal interactions, movements, and even reproductive behaviors, making wildlife cameras an essential tool for wildlife management and conservation.
