RESULTS: GROWTH CURVES
Growth curves are excellent tools to conceptualize and visually compare growth patterns of different species. These curves were developed using both Xuru's Regression Tools as well as the nls function in R x64 3.4.0. These graphs depict that the SDM was correct in its' habitat projections. Pinus contorta is a strong competitor in Sweden (a suitable projection) and is outcompeted in Germany (unsuitable projection).
There is a difference between the growth patterns of these species in each respective country. In Sweden, Pinus contorta outcompetes Pinus sylvestris after age 10 (Figure 19) . In Germany, the observed growth of Pinus sylvestris is far stronger than Pinus contorta, regardless of age (Figure 20).
Similarly to Figure 19 , Pinus contorta outcompetes Picea abies in Sweden (Figure 21). These growth curves are very close to one another, showing their similar growth patterns. However, Pinus contorta is outcompeted in Germany (Figure 22).
It is difficult to differentiate the three growth curves in Sweden (Figure 23) . This is a strong indication that Pinus contorta would be competitive with the other established forestry species. In Germany, growth performances of all 5 local species were much stronger than that of Pinus contorta (Figure 24).
