Biomass Estimation For Some Shrubs From Northeastern Minnesota, David F. Grigal, Lewis F. Ohmann

Aspen Bibliography

Biomass prediction equations were developed for 23 northeastern Minnesota shrub species. The allometric function was used to predict leaf, current annual woody twig, stem, and total woody biomass (dry grams), using stem diameter class estimated to the nearest 0.25 cm class at 15 cm above ground level as the independent variable.
