VISUALIZING FOREST AGE CLASSES, ROTATIONS, amp FOREST CARBON DATA 4 DATA ANALYSIS METHODOLOGY EXPLAINER number of years between measurements. We also compute tree mortality, which is the amount of wood in trees that die between inventories, which equates to a transfer of carbon from living trees to dead trees a different carbon pool.

Compared to FIA-based estimates, VCT-based estimates were statistically significantly higher for forest age classes of 1-5, 6-10, and 11-15 years, and significantly lower for the 16-20 year age class. Ongoing studies are examining causes and potential corrections for discrepancies between VCT- and FIA-based estimates of young forest in Wisconsin.

To reduce the unbalanced sample size across age classes, we weight-sampled the FIA data with decadal age classes underrepresented in the dataset before including the FIA data with higher weights. The weights for each decadal class were calculated following Eq. The forest age map used here corresponds to a tree cover threshold of 10

The age of forest stands is critical information for forest management and conservation, for example for growth modelling, timing of management activities and harvesting, or decisions about protection areas. used hyperspectral HyMap data from the spectral angle mapper to classify Norway spruce and Douglas fir age classes on a study site

After combining the cover classes into FLALOTH, and assessing forest age classes on the map, we observed that 17,379 ha of forest land corresponding to age class A 120-75 year, whereas only 6,120 ha and 6,680 ha corresponded to class B 74-42 years and class C 41-10 years, respectively.

The accuracy of both maps and that of each forest age class were assessed using a confusion matrix, that is, a table that measures the agreement between classes in the map and classes on the ground Campbell and Wynne, 2011. The overall accuracy of the classified forest age map was calculated by dividing the total number of correctly
