| + | The abundance of large trees is an important factor for biodiversity. You can define your own result variables and include these in reports and also in optimization models. Up to ten result variables can be defined for volume or number of trees of a certain species group. A diameter criteria is given for each variable. | ||
| + | |||
| + | To define a new result variable, follow these steps: | ||
| + | # In menu Tools, select User Results. | ||
| + | # Click Add Row. | ||
| + | # Name your variable in column Alias, for example "Large aspens >= 30 cm". | ||
| + | # Select species in column Species. Currently there is only support for species groups. Use the option "Select multiple valus..." to include more than one species group in the variable. | ||
| + | # In column Variable, select Volume or Stems depending of what you are interested in. | ||
| + | # Defined the diameter criteria in column Min Diameter. | ||
| + | # Repeat steps 1-6 for each variable you want to add. | ||
| + | # Click OK when you are done. | ||
