Use herbicides after tree planting Forest Conservation

A replicated, randomized, controlled study in 1992-1995 in boreal forest in Sweden (1) found that applying herbicide increased the biomass of English oak Quercus robur seedlings. Dry weight (g/seedling) of stems (herbicide: 1.25-1.75; untreated: 0.45-0.50) and leaves (herbicide: 0.95-1.20; untreated: 0.25-0.35) were lower in untreated than herbicide plots. Data were collected in 1995 in herbicide and untreated (control) plots (25 m2) established in summer 1992 in each of six clearcut and six shelterwood (12.5 m2/ha basal area retained) blocks (cut in 1990). All plots were planted with oak seedlings in November 1992.
