... site regeneration of pure and mixedwood boreal forests. Following tree harvesting, mechanical site preparation is often used to improve microsite conditions to promote conifer seedling establishment or natural regeneration. Chemical and mechanical site preparation and stand tending control competing...

... of an algorithm to account for the effects of slope and aspect on solar radiation, the addition of a litter layer storage model and the development of a simple wetland model to represent the bogs and fens found in boreal forests. In addition, SWAT_BF has been modified so that water fluxes from upland...

... (inorganic) forms of nitrogen (nitrate-nitrite and ammonium) typically constitute a small portion of forest soil nitrogen pools (Fenn et al. 1998). In northern temperate (i.e., boreal) forests, wildfire and forest harvest are dominant disturbances that affect nitrate and ammonium availability in soils in two...

...J.D. MacDonald; J.R. Kiniry; G. Putz; E.E. Prepas To simulate the effects of tree harvest on boreal forest catchment hydrology, the vegetation growth model within the soil and water assessment tool (SWAT) must reproduce the successional stages of forest reestablishment. The agricultural land...
