Sampling

DNA based fungal inventory since 2015

• UNFCCC & the Kyoto protocol

• Land-Use, Land-Use Change and Forestry

• Swedish NFI and SFSI data

• Pools based on the SFSI:

- Dead organic matter

- Soil carbon

Emissions (+) and removals (-) of CO2 from different C pools

• Natural Acidification Only

• Target on forest soils

• State and development
