Description

The Lower Foothills Natural Subregion occupies a broad northwest-to-southeast belt between the Bow River Valley to the south and Grande Prairie to the north, with outliers in the Swan Hills and Pelican Mountains to the east, and the Saddle Hills to the north. This guide represents the analysis of 2120 plots described in the Lower Foothills subregion, representing 119 community types. These community types were described in 15 ecological sites. The dominant plant species, canopy cover, soils and environmental conditions are outlined for each type. Included in this approximation is a crosswalk table to the Alberta Wetland Classification System (AWCS), new soil type descriptions and successional changes on harvested deciduous community types.

Description

The Electronic Distance Measurement (EDM) Calibration Baseline Lengths listings give the pillar-to-pillar (slope distance) baseline length values for the four EDM calibration baselines in Alberta (Lethbridge, Calgary, Edmonton and Grande Prairie). These values are based on precise measurement and adjustment undertaken by Geodetic Survey Division of Geomatics Canada (NRCan). All of the baselines are re-measured and adjusted, and new values published on a five-year basis. Please note that on each listing, there is an adopted date that signifies when the slope distances were formally published by the Surveys Section
