Native forests and woodlands can be managed or unmanaged.  Examples of use cases for this category include conservation forests and forests managed for timber production.

Native forests and woodlands can include many different biomes, depending largely on climate and altitude, including IUCN-GET biomes T1 (Tropical-subtropical forests), T2 (Temperate-boreal forests & woodlands), and Ecosystem Functional Group T4.4 (Temperate woodlands).

Notes

Forest extent is highly dependent on the definition of forest, so the definition used should be stated.

Australia’s definition of forest specifies a minimum existing or potential crown cover of 20%, a minimum mature or potentially mature stand height exceeding 2m, and stands dominated by trees usually having a single stem (SoFR 2018, p. 48).

By comparison, the international FAO/UN definition is over 0.5 ha land area with tree canopy coverage of more than 10% and tree height of taller than 5m at the time of observations or at maturity.

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.

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.

Options for determining an appropriate price include average prices from ERF auctions, estimates of the marginal cost of carbon sequestration or emissions abatement for, or a social cost of carbon based on exchange values (all for the relevant period).

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.
