Explanatory note: 6 different equations are used to determine the biomass of aerial ligneous vegetation (B) (DBH: diameter at breast height; DSH: diameter at stump height; D15: diameter at height of 15 cm).

[A1] B = b0× DBHb1

[A2]8 ln B = b0 + b1 × ln DBH

[A3] B = b0 × DSHb1

[A4] ln B = b0 + b1 × ln DSH

[A5] B = b0 × D15b1

[A6] D15 = (DSH – a15)/b15

1 The equation for A. rubrum is used.

2 The equation for A. rugosa is used.

3The equation for Salix sp. is used.

4The equation for P.mariana is used.

5 The equation for Populus sp. is used.

6 The equation for P.mariana is used.

7 The equation for P. pensylvanica is used.

8 To obtain the value B, the result of the equation must be converted to an exponent.
