May 22, 2012 Report No. 1114920016-R-Rev0-2000 12 GMSMON-17 WILLISTON RESERVOIR TRIBUTARY HABITAT REVIEW measured as the length of canopy that intercepted the line (Canfield 1941). Efforts were made not to disturb each transect by walking and samples of unknown species were collected away from the transect for future identification. In addition to line-intersect transects, a 5 x 5 metre quadrat was set up at the starting point of each transect parallel to the stream, and all trees whose stems were more than 50% within the quadrat were counted. A 5 m pole was used to establish the plot boundary. Trees were marked with tree tags placed low on the bole and positioned towards the centre of the plot. Tree heights were visually estimated and diameter at breast height (DBH) was measured for all trees determined to be within the quadrat. Trees were placed into one of four tree layers, defined as follows: Layer 1: great than 12.5 cm diameter at breast height (DBH = 1.3 m), Layer 2: 7.5 to 12.5 cm DBH, Layer 3: 1.3 m tall to 7.5 cm DBH, and Layer 4: up to 1.3 m tall. A photo reference location was also established, placed 2.5 m from the start of the line-intersect transect, to visually capture both the line-intersect transect and the tree quadrat. Photos were taken, using a Pentax Optio W8 camera, upstream (through the tree quadrat), perpendicular to the stream (along the line-intersect), downstream, and across the stream. The azimuth and height of the camera for each photo was recorded and a surveyor’s pole was used to ensure consistency. 3.0 RESULTS 3.1 Climate Data Snow packs for the 2011 study year are compared with historical means from two locations which are assumed to most closely resemble conditions at the study sites: Aiken Lake (Station ID: 4A309) for the northern locations and Pine Pass (Station ID: 4OA2P) for the southern. Table 6 provides the details of these survey stations. Table 6: Snow Pillow Survey Locations and Relative Distances from Trial Tributary Locations.
