| Abstract: | Presents reconciliation of differences between field- and remote sensing-based approaches to measuring vegetation changes caused by climate warming over period 1986-2006. Compares trends among vegetation communities from two separate Landsat classifications in Canada's eastern and western forest-tundra transition zone, and also from 1 km AVHRR database recently developed over Canada. Results, together with those obtained from experimental warming, suggest that magnitude difference in Normalised Difference Vegetation Index (NDVI) increase between lichen and vascular vegetation is related to increasing vigour and biomass of vascular vegetation, in contrast to physiological impairment of lichen due to short-term secondary effect of temperature on moisture. |
