Potential measures include expanding the area of protected forests, lengthening rotations and thinning intervals or favouring mixed and uneven-aged stands. At the same time, changing climatic conditions have made it necessary to study adaptive forest management measures that maintain productivity and forest health under the changing conditions.
ForModGroup are involved in several projects where these issues are studied (click links to open):
In these projects, our models are developed further to apply more widely to new situations. The main applications are to the PREBAS model to country-wide projections that utilise multisource forest inventory data as input initial state at 16 m resolution (collaboration with Luke) and selected climate change scenarios for weather (collaboration with Finnish Meteorogical Institute). Model simulations compare different forest management options under scenarios defined together with stakeholders.
Example output from simulations: Woody growth in pine under SRESa1b for different N uptake assumptions: Poor (top), Default (middle) and Rich (bottom).
