Calculate representative area of trees

No representative area is calculated for a dead tree. If the project includes concentric circles, the representative area is always calculated relatively to the whole plot area. Representative area is then often applied as tree weight. Each single tree measured/described on the plot/subplot is getting adequate area share from total area of the inventory plot based on its dimensions. This allows to calculate area statistics for tree descriptive information (e.g. Total area of dead forest, Species composition etc.).
