Project and Baseline Scenario

The derivation of the project and baseline scenario is project-specific. The calculation is transparently shown in the PDD.

With the project development, the two partially complementary silvicultural approaches "Adaptation" vs. "Mitigation" are described silviculturally. They are project-specific and influence both the project and the baseline scenario as well as the risk assessment. Using a forest management concept, the expected project impact as well as the additional impact are described and backed with indicators (e.g. tree species distribution).

The derivation of the baseline scenario is an important part of project development. The baseline scenario is project-specific and takes place in the context of risk assessment (current forest condition, expected impact of climate change, etc.). The considerations are transparently shown and coordinated with the forest manager and the project owner. Possible risk buffers are described transparently and justified.

The responsible authorities for forest management are informed and consulted.

Conversion Factors

Roundwood of Living Trees

The report on the Swiss National Forest Inventory four LFI4 (REF Ref. 16a, Table 101, p. 118) provides conversions from roundwood of living trees to coniferous and deciduous timber for the LFI production regions. The wood density (D), root-shoot ratio (R), and biomass expansion factor (BEF) are already included:

Conversion factor for stocks in biomass

Based on the general assumption of an average carbon content of 50% of dry biomass (Brändli et al. (2020) Ref. 16a, Thürig et. al (2008) Ref. 06)), the average carbon content of tree biomass and thus also with regard to roundwood volume can be calculated for the five LFI production regions.

Harvest Losses

Harvest losses refer to those portions of the harvest quantity that remain in the forest. In the measurement of standing timber use, recognized estimation and calculation procedures are applied to infer from the harvested masses m3 to the standing harvest volume in m3 e.g. Ref. 42.

Conversion from lying mass without bark to solid cubic metres in bark (Ref. 42)

Status of Natural Forest Reserve

Natural forest reserves are accepted under the method if they have official status. The assurance is usually provided by the cantonal forestry authority.

Earmarking of Revenues

The project owner may, on a voluntary basis, provide for an earmarked use of funds for revenues from the project as part of the project development. A suitable monitoring indicator is defined for this purpose, which will be checked within the framework of the monitoring.
