A second year of wildlife monitoring studies was undertaken along the Norman Wells to Zama oil pipeline route from April 1985 to May 1986 to assess the effects of the pipeline right-of-way (ROW) on local wildlife distributions and abundance. Study components included: 1. completion of two aerial surveys designed to provide comparable estimates of moose densities adjacent to and several km from the ROW (November 1985 and March 1986); 2. completion of two track count surveys designed to provide comparable, habitat-specific estimates of furbearer track densities at set intervals from the ROW (November 1985 and March 1986); 3. summarization of track observations recorded by Hunters and Trappers Association (HTA) members during snowmobile coverage of the ROW (November 1985 to April 1986); and 4. summarization of wildlife observations recorded by Interprovincial Pipe Line (IPL) personnel during weekly surveillance flights of the ROW (April 1985 to May 1986). ...

Watercrossing monitoring along the Norman Wells to Zama Pipeline was initiated in 1984 to identify any physical conditions which may result in negative impacts to the aquatic resource along the pipeline route. Specifically, the approaches and instream ditchline of watercrossing were examined for stability, any pipeline-related alterations to the watercourse were evaluated, upstream/downstream areas were compared to evaluate potential sedimentation concerns, and watercrossings were assessed to determine whether the right-of-way was contributing to the degradation of water quality or aquatic habitat. All assessments were based on visual examinations. During July, 1984 emphasis was placed on 20 major watercrossings along the pipeline route, although virtually all watercrossings were examined during that reconnaissance. This program was repeated in July, 1985, at which time detailed examinations of 34 watercrossings were conducted, and the remainder of the watercrossings were examined from the air for obvious potential aquatics concerns. The latter program was repeated between July 14 and 16, 1986. One of the most common concerns identified during the reconnaissance programs was subsidence of ditch backfill on stream approaches and stream crossings, which was often associated with ponding at the stream crossing. ... Erosion was again noted at many stream crossings during 1986, although in the vast majority of cases it was minor in nature. ... A unique concern which was noted was the apparent failure to revegetate the islands at the Whitesand Creek tributary crossing .... Water was also noted to be seeping from several wood-chip protected slopes, which is identified as a potential concern if this seepage is indicative of permafrost degradation in the slope and thus potential slope instability. ...

... Detailed watercrossing evaluations were completed for the 34 major crossings along the pipeline route in each survey year; the results of the 1987 program are presented together with a photograph of the conditions at each crossing in this document. A summary of relevant comments on the 181 minor watercrossings is presented in tabular form, as was the case with previous reports. No aquatic concerns which were judged to require maintenance activities were noted at any of the minor crossings in 1987, while only very few were apparent at the larger watercourses. The results of the four year monitoring program are described, with emphasis placed on common concerns noted during these surveys and the condition of watercrossings at the time of the 1987 reconnaissance. Two major concerns were noted throughout the program, the first of which was subsidence on the ditchline at watercrossings. ... The second major concern commonly noted was insufficient streambank protection on main watercrossings. ... (Au)

In January 1985, a three year monitoring program was undertaken along the Norman Wells-Zama oil pipeline to assess the effects of pipeline construction and operation on the abundance, distribution and local movements of wildlife within the pipeline corridor. Study components included: (1) the identification of major habitats within the pipeline corridor, based on botanical characteristics, to aid in the interpretation of wildlife abundance and distribution data collected in the vicinity of the right-of-way (ROW); (2) track density surveys, designed to provide comparable estimates of furbearer track densities at various distances from the ROW; (3) browse utilization measurements (for hare and moose), designed to provide comparable estimates of browsing intensity at various distances from the ROW; (4) monitoring of track responses to the ROW, designed to assess the ROW-crossing behaviour of various wildlife species; (5) aerial surveys, designed to provide comparable estimates of moose densities adjacent to and several km from the ROW; (6) summarization of track and wildlife observations recorded by Hunters and Trappers Association (HTA) members during snowmobile coverage of the ROW; (7) summarization of wildlife sightings along the ROW by construction and pipeline surveillance personnel. ...
