The primary method for assessing the health of an ecosystem involves monitoring key indicators, such as species diversity, population dynamics, and the presence of invasive species. Biomonitoring, which includes assessing water quality and habitat conditions, provides insights into the ecological integrity of an area. By employing a combination of direct observations and measurements, ecologists can evaluate ecosystem resilience and identify any stressors that compromise biodiversity. This assessment is vital for implementing conservation strategies and ensuring sustainable management of natural resources.
