Ecological monitoring
Ecological monitoring is the repeated measurement of organisms, habitats, or environmental conditions to detect ecological change over time.
Indicator species: A species whose presence, abundance, or condition provides information about environmental conditions. Its measured response can signal changes in habitat quality or ecosystem stress.
Biodiversity monitoring: The repeated assessment of biological diversity across species, genes, or ecosystems. It applies ecological monitoring to changes in the variety and composition of life.
Ecology: The study of relationships among organisms and between organisms and their environments. Monitoring measures patterns and processes that ecology seeks to explain.
Ecological survey: A structured assessment of ecological conditions at a particular time or across a defined period. A one-time survey describes conditions, while monitoring depends on repeated measurements.
Bioindicator: An organism or biological response used to assess environmental conditions or exposure to stressors. Biological measurements can reveal effects that physical measurements alone miss.
Water quality monitoring: Repeated measurement of physical, chemical, or biological properties of water. Aquatic monitoring tracks conditions such as nutrients, contaminants, and biological health.
Ecosystem: A community of organisms interacting with one another and with their physical environment. An ecosystem is a common unit whose structure and function monitoring tracks.
Remote sensing: The collection of information about objects or areas from a distance, commonly using sensors. Satellite and aerial observations expand spatial coverage but may not capture local biological detail.
Sampling design: The plan for selecting observations, locations, timing, and effort in a study. Consistent, representative sampling makes comparisons across dates and sites meaningful.
Forest health monitoring: The repeated assessment of forest condition, including tree vitality, damage, and regeneration. Forest programs use recurring measurements to detect stress and shifts in ecosystem condition.
