The development of a Land Suitability Map was proposed to identify the land base suitable for the growth and establishment of tree species in order to help assess the cost effectiveness of a large-scale afforestation efforts. Evaluating and mapping the land-base suitable for afforestation was considered essential to: 1) identify optimal sites for establishing high-yield, area-based plantations; 2) assess the economically feasibility of large-scale afforestation; 3) supplement existing growth and yield information, and; 4) assess production potential.

Using map-based modelling techniques, the CFS has matched areas with similar biological and climatic traits to areas with similar variables influencing tree productivity. Local experts have been consulted to help validate and fine tune the model. This modelling exercise has resulted in ‘Land Units’ that will be monitored to ensure that the observed attributes are consistent with the model’s output.

A land suitability classification system is being developed for each tree species under consideration for afforestation under FAACS and Forest 2020 PDA. The information produced by the Land Suitability Model will be coupled with information on species growth requirements to classify each of the Land Units. This will identify the land base suitable for afforestation and estimate expected output on those suitable lands.

The output of this model will be useful in producing management strategies and identifying areas of high growth potential.

The Canadian version of this model has been completed for hybrid poplar. Remaining species are currently being modelled through the Forest 2020 PDA.

Results of the Land Suitability modelling research are currently under review and will be made available as soon as possible.
