The resulting horizontal uncertainty in mapping of flood limits is a function of slope ([+ or -] 5 m at a beach face slope of 6[degrees]; [+ or -] 8 m at a backshore slope of 3.5[degrees]).
Backshore slopes are fairly consistent throughout, except where higher-relief bedrock is exposed.
Cover was significantly greater in both the backshore and primary dunes at Site 1 (Table 1).
Species richness was greater at Site 1 than at Site 2 (Table 2), especially in the backshore zone.
The landscape of the study area consists of a foreshore bounded by Hudson Bay and either (1) shallow quartzite rock cliffs, possibly supporting aeolian dune formations, or (2) a backshore area containing aeolian dune formations (Fig.
The aeolian dunes within the backshore region are partitioned into two communities: the open dune community and the stable dune community.
- Despite notable dissimilarities between foreshore and upland regions on the Canadian Shield in terms of tree composition and litterfall (Brusnyk and Gilbert, 1983; Euler, 1983; France et al., 1998), the regrowth of riparian boreal forests after timber harvesting is not different from that found previously for backshore boreal forests within the same region (Ellis and Mattice, 1974).
Elevation change was measured at more than 100 wooden pins (1.5 cm diameter) installed at 5m intervals in a grid that extended across the backshore, foredune and blowout on the dune ridge (Figure 4).
