| + | A special approach has also been developed to adapt the response of the growth models used in Heureka. The principal idea is to augment or shift the growth function when climate changes. This is done by changing tree ages; the size to age relation of trees is a critical variable in all growth functions used in Heureka. In the system, we differ between actual tree age and biological tree age. The biological age is the one subject to adjustment. | ||

| + | The climate response model affects the following variables directly: | ||

| + | *Site index (SIS) | ||
| + | *Vegetation index | ||
| + | *Temperature sum | ||
