Sown pastures may be used for livestock grazing or forage (e.g. harvesting for hay). Other examples include lawns and grass sporting fields. Sown pastures may be irrigated and/or have drainage modifications, and are often subject to artificial nutrient supplementation or other soil ameliorant application.
This category corresponds to IUCN-GET Ecosystem Functional Group T7.2 (Sown pastures and fields).

Notes
Grazed biomass provisioning is technically an intermediate service provided to livestock, with the livestock then providing the final service of livestock provisioning. However, following SEEA-EA 2021 (para. 6.56) it is recommended that grazed biomass provisioning is considered as the primary ecosystem contribution. Where there is a mix of ecosystem contributions and human contributions (e.g. through addition of fertiliser) to the grazed biomass provisioning service, ideally the ecosystem contribution should be estimated as a percentage of the total. Likewise, if measured via a proxy such as the stocking rate, corrections should be made for other inputs, such as supplementary feed (unless sourced from the same ecosystem, over the same time period).
Units

What are tiers?
Tier 1
Estimate monetary value of ecosystem contribution from residual value. The residual value method (NCAVES and MAIA, 2022) involves deducting user costs (e.g. costs of production, extraction/harvesting and processing, plus financial costs such as depreciation and return on produced assets, minus subsidies on extraction, plus taxes on extraction) from revenues from extracted/harvested products, to derive a monetary value for the ecosystem contribution.
Tier 2
Estimate monetary value of ecosystem contribution from replacement cost, or how much it would cost to feed livestock if the grazed biomass was not available (NCAVES and MAIA, 2022).
Tier 3
Estimate monetary value of ecosystem contribution from observed prices. For example, if grazed land is privately owned and has a market price, then either an explicit price from a rental market or an implicit price derived from the market value of land, assuming a market rate of return, may be used to represent the right to use grazed biomass (NCAVES and MAIA, 2022).

Notes
The ecosystem service of carbon retention is measured by the opening stock of retained carbon (see SEEA-EA s. 6.4.3, pp. 139-140) as a proxy for the flow of this service. The scope conventionally covers above- and below-ground living and dead biomass and soil carbon up to 2m depth. Carbon retained in harvested wood products should not be considered an ecosystem service (SEEA-EA, s. 6.4.3, pp. 139-140), although it could be included in an entity’s carbon account or impact statement. An increase in retained carbon from year to year should equal the flow of the ecosystem service of carbon sequestration.

Notes
Technically, the full price paid in ERF auctions per tonne of CO₂e sequestered is for the combined services of carbon sequestration and retention for 100 years. However, it can be assumed that the price component for annual retention is small, therefore the ERF price approximates the current value of carbon sequestration services.

Notes
Species richness can be defined as “The number of species within a given sample, community, or area” (IPBES). It is one way of measuring species diversity, which is itself only one aspect of overall biodiversity. The concept of richness can also be applied at other levels, from genetic (e.g. the number of distinct genotypes within a species) to the number of represented genera, families, etc. It can be useful to supplement richness information with information on abundances or relative abundance distributions.
Depending on the purpose of measurement, and the measurement resources available, the concept of species richness may be applied to certain sets (e.g. plants, mammals, birds, invertebrates, endemic species, etc.). It is important to recognise that observations from one set may not apply to other sets in the same area.
It is usually not feasible to count all species, even within a limited set, within a given area. Therefore some form of sampling method is usually applied to come up with a sample set that can feasibly be measured. Many different sampling methods may be used, and the number of samples required will depend on the measurement objectives (e.g. desired accuracy and confidence), the sample measurement method (e.g. size of sample areas), and the actual variation in the measured quantity across the given area. There are also many different measurement methods and technologies at the sample measurement level (e.g. pit traps for insects, camera traps for animals, acoustic methods for birds). There is no single ‘right’ method that applies in all circumstances. Whatever method is used, it is important that it should be applied consistently for a given site over time, and appropriate to the measurement objectives and ecosystem type. Measurements using different methods may not necessarily be comparable.
