ABE outputs

ABE provides several outputs with different spatial/temporal grain (see organizing outputs, and other iLand outputs).

Annual harvests and harvest plan on unit level.

Table Name: abeUnit
The output provides planned and realized harvests on the level of planning units. Note that the planning unit area, mean age, mean volume and MAI are only updated every 10 years. Harvested timber is given as 'realizedHarvest', which is the sum of 'finalHarvest' and 'thinningHarvest.' The 'salvageHarvest' is provided extra, but already accounted for in the 'finalHarvest' column

finalHarvestdoubletotal harvested timber of planned final harvests, m3/ha*yr
thinningHarvestdoubletotal harvested timber due to tending and thinning operations, m3/ha*yr
salvageHarvestdoubletotal harvested timber due to salvage operations , m3/ha*yr


Annual stand output (state).

Table Name: abeStand
This output provides details about the forest state on stand level. The timber is provided as standing timber per hectare.
The output is rather performance critical. You can use the condition XML-tag to limit the execution to certain years (e.g., mod(year,10)=1 ).

Detailed annual stand output (state).

Table Name: abeStandDetail
This output provides details about the forest state on species- and stand level. This output is more detailed than the abeStand output.
The output is rather performance critical. You can use the condition XML-tag to limit the execution to certain years (e.g., mod(year,10)=1 ).

Annual harvests on stand level.

Table Name: abeStandRemoval
This output provides details about realized timber harvests on stand level. The timber is provided as standing timber per hectare. The total harvest on the stand is the sum of thinning and final.
