Tools in Assessing Climate Change Flashcards
Forests are the ________
on earth as they hold more than 80% of all terrestrial above ground
carbon (AGC) and more than 70% of
all soil organic carbon (SOC).
largest carbon pool
forests are found to play
a key role in the emission mitigation by sequestrating the atmospheric carbon into biomass and soil, and it plays an important role in the _______
global carbon cycle
Carbon Stock Assessment
- ______ the amount of carbon stocked in the individual component of the forest or the forest as a whole
calculating
Carbon Stock Assessment
- measures the _______ and its components or
an ecosystem component to sequester Carbon
potential of a forest
Carbon Stock Assessment
- “A tree is ____ carbon”

- dry matter weight of organic material
- the total mass of living organisms
Biomass
- includes the biomass of tree, understory and herbaceous vegetation
Aboveground biomass (AGB)
- includes the biomass of the soil and roots
Belowground biomass
- is the dry matter weight of organic material (above-or belowground, live or dead).
Biomass
- is a reservoir or a system which has the capacity to accumulate or release carbon.
- Examples are forest biomass, wood products, soils, and atmosphere.
Carbon Pool
- is the natural features that absorb CO2, such as forests or seas.
Carbon Sink
- is the absolute quantity of carbon held within a pool at specified time.
Carbon stock
- are standing dead tree and fallen logs.
Course wood debris (CWD)
- is the L and O horizon comprising of dead plant material that lies on top of the mineral soil.
Litter
- is dead wood material in the forest that is beyond 5cm dbh and 0.5m length.
Necromass
- rate is the yearly sequestration of CO2, taken from the difference between
sequestration observation for two time periods divided by the number of years elapsed.
Sequestration
- is the amount of carbon derived from the weight of soil in Mg multiplied by %SOC. The %SOC being derived from its relations to %OM.
Soil organic carbon (SOC)
- plants are undergrowth which includes saplings, wildlings and grass
Understory/herbaceous
