Erratum to: Forest Ecosystems 2016, 3:6 DOI: 10.1186/s40663-016-0065-8

Following publication of the original version [1] of the article in Forest Ecosystem, it was brought to our attention that in the PDF file, Equation 1 is not presented correctly on page 3.

It should be presented like the following:

$$ {\mathrm{y}}_i={\alpha}_1+{\alpha}_2\cdotp {\mathrm{Aspect}}_i+{\alpha}_3\cdotp \mathrm{T}\mathrm{R}\mathrm{W} + {\alpha}_4\cdotp \mathrm{C}\mathrm{A} + {\alpha}_5\cdotp {\mathrm{Aspect}}_i:\mathrm{T}\mathrm{R}\mathrm{W} + {\alpha}_6\cdotp {\mathrm{Aspect}}_i:\mathrm{C}\mathrm{A} + \mathrm{T}\mathrm{ree} + \mathrm{Year} $$
