The quality of an ecosystem measured in terms of its abiotic and biotic characteristics. Condition is assessed with respect to an ecosystem’s composition, structure and function which, in turn, underpin the ecological integrity of the ecosystem, and support its capacity to supply ecosystem services on an ongoing basis. Measures of ecosystem condition may reflect multiple values and may be undertaken across a range of temporal and spatial scales. - Physical state characteristics: physical descriptors of the abiotic components of the ecosystem(e.g. soil structure, water availability) [https://seea.un.org/content/common-typology-ecosystem-characteristics-and-ecosystem-condition-variables] - Chemical state characteristics: chemical composition of abiotic ecosystem compartments (e.g. soil nutrient levels, water quality, air pollutant concentrations) [https://seea.un.org/content/common-typology-ecosystem-characteristics-and-ecosystem-condition-variables] - Compositional state characteristics: composition / diversity of ecological communities at a given location and time (e.g. presence / abundance of key species, diversity of relevant species groups) [https://seea.un.org/content/common-typology-ecosystem-characteristics-and-ecosystem-condition-variables] - Structural state characteristics: aggregate properties (e.g. mass, density) of the whole ecosystem or its main biotic components (e.g. total biomass, canopy coverage, chlorophyll content, annual maximum NDVI) [https://seea.un.org/content/common-typology-ecosystem-characteristics-and-ecosystem-condition-variables] - Functional state characteristics: summary statistics (e.g. frequency, intensity) of the biological, chemical and physical interactions between the main ecosystem compartments (e.g. primary productivity, community age, disturbance frequency) [https://seea.un.org/content/common-typology-ecosystem-characteristics-and-ecosystem-condition-variables] - Landscape/seascape characteristics: metrics describing mosaics of ecosystem types at coarse (landscape, seascape) spatial scales (e.g. landscape diversity, connectivity, fragmentation) [https://seea.un.org/content/common-typology-ecosystem-characteristics-and-ecosystem-condition-variables] --- Ekosysteemin laatu mitattuna sen abioottisilla ja bioottisilla ominaisuuksilla. Kunnon arvioinnissa otetaan huomioon ekosysteemin koostumus, rakenne ja toiminta, jotka puolestaan ​​tukevat ekosysteemin ekologista eheyttä ja tukevat sen kykyä tarjota jatkuvasti ekosysteemipalveluja. Ekosysteemin kunnon mittaukset voivat heijastaa useita arvoja, ja niitä voidaan suorittaa useilla aika- ja paikkamittauksilla.
