Ecological Studies on the Revegetation Process of Surface Coal Mined Areas in North Dakota. 6. Relationship Between Cover and Aboveground Biomass.
NTIS: PB/83-171371 :52 pages
A study was done to evaluate the predictability of aboveground biomass production on revegetated mined sites and adjacent native prairies using plant cover estimates made with the point frame method. The predictability of biomass production by cover estimates bears on the need for measurements of both plant cover and aboveground biomass in assessing revegetation success. A positive, statistically significant correlation was demonstrated between plant cover (estimated by the point frame method) and aboveground biomass (estimated by the harvest method) regardless of community type (mined or native), species composition, diversity, or level of biomass production. However, the latter did have their effects on the relationship and must be accounted for in any predictive equations; that is, the predictive equations must be considered site specific.
