“…Despite both fens and bogs being peat accumulating environments, there are many differences between fens and bogs. Fens are minerotrophic peatlands as they are supported by surface and groundwater inputs which provide nutrients leached from underlying bedrock and soils from their watershed (Rocchio et al, 2021) Bedford, 1999;Andersen et al, 2017;Dube et al, 2011;Howie & Meerveld, 2016), making it a very acidic environment (pH 4.0 to 4.8). The dome height of a raised bog increases gradually over decades due to peat accumulation.…”

Remotely piloted aircraft systems are increasingly used as a remote sensing platform for peatland researchers to monitor changes in vegetation height/composition/structure. In this work, an RPAS was flown to collect aerial images over Alfred Bog, a domed peatland complex located in Eastern Ontario. The images were processed with a photogrammetry technique referred to as Structurefrom-Motion (SfM) which can be used to create 3D point clouds of a x by y transect. The point cloud results were used to assess the utility of extracting ground terrain and vegetation height as compared to a transect field survey. This field survey was completed with a Trimble Catalyst RTK GNSS to record ground elevation and maximum vegetation height of the canopy top. The results from this research suggest that terrain information could not be extracted at all from the generated point clouds. Although, a digital surface model can be generated to model the canopy top and crown area.

Classification of vegetative lagg types and hydrogeomorphic lagg forms in bogs of coastal British Columbia, Canada

Abstract: Key Messages A classification scheme was developed for laggs (marginal transition zones) of bogs. Regional differences in vegetative lagg types were observed. Half of the studied laggs differed from the classic notion of a lagg as being topographically confined.
