AbstractBog and fen wetland complexes comprise a large percentage of ground cover in central Labrador and contain some of the largest peatlands in North America. The region experiences long cold winters and short cool summers, resulting in a limited growth period. The level of moisture saturation, chemistry, topography and climate influences the development of wetland systems. Consequently, slight changes in these environmental factors can significantly alter vegetation species and health. As persistent cloud cover often limits the utility of optical data in Atlantic Canada, the value of using the all-weather capabilities of radar data is evident. Temporal sequences of Radarsat images (C-HH) were acquired in May, June and August 1999, during which four Radarsat scenes, with incidence angles spanning 20-49° (Standard 1, 4, 7 and Fine 1) were acquired for each time period. Throughout the study period, 6 ERS-2 images (C-VV) were also acquired. This paper describes changes in radar backscatter as a function of incidence angle, vegetation structure and polarization.
