Estimating Plant Biomass For Undergrowth Species Of Northeastern Minnesota Forest Communities, L.F. Ohmann, D.F. Grigal, L.L. Rogers

Aspen Bibliography

Knowledge of the plant biomass comprising a forest community is important to many aspects of multiple-use management. Direct measurement of biomass, however, is expensive and time-consuming to under-take each time biomass information would be useful. Fortunately, other measurements that can be made in the field less expensively or more easily can be used for estimating biomass.

Clone Expansion And Competition Between Quaking And Bigtooth Aspen Suckers After Clearcutting, Donald A. Perala

Aspen Bibliography

The ability of quaking and bigtooth aspens (Populus tremuloids Michx., P. grandidentata Michx.) to vegetatively regenerate dense stands of root sprouts (suckers) is well documented (Brinkman and Roe 1975). Tens of thousands of suckers per hectare are commonly produced when stands are killed by fire or removed by clearcutting.

A Study Of Root Biomass In An Engeimann Spruce-Subalpine Fir Stand In Northern Utah, Larry O. Gadt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Biomass of roots in the top 6 inches of soil profile was measured . This weight was then used in a stepwise multiple regression to test correlations between root biomass and above ground merisurational parameters.

Total biomass of all roots was 9822 ± 2810 pounds per acre oven dry. Spruce roots weighed 4417 ± 997 pounds per acre; of this spruce roots less than 0.125 inch diameter weighed 2023 ± 347 pounds per acre and biomass of spruce roots greater than 0.125 inch diameter was 2394 ± 8S3 pounds per acre. Total fir roots weighed Sl56 ± 2687 pounds per …
