Aerial biomass distribution in an undisturbed and disturbed subarctic bog
During powerline construction, a portion of a wooded (Picea mariana) peat plateau in northern Manitoba was stripped of surface vegetation. Seven years later, aerial biomass of plants recolonizing the surface of the disturbed area was estimated to be 2098 kg ha −1 , only 26.4% of the undisturbed port...
