The third annual monitoring of the Norman Wells to Zama pipeline revegetation program was carried out in late August, 1986. In total, 130 transects were inspected, 72 located in areas first seeded in 1984 and 58 in areas first seeded in 1985. In addition, a general overview of the revegetation status of the right-of-way was conducted. This report presents the results of the 1986 monitoring program and discusses the development of plant cover along the pipeline since the first seeding. (Au)

The 1986/97 Winter Restoration Program on the Norman Wells to Zama Pipeline was organized into four (4) major restoration contract packages, ... In each case, revegetation activities generally took place as the work proceeded. Each contractor applied the seed and fertilizer using hand type mecanical (cyclone) seeders which generally broadcast across a 5 to 7 meter wide strip. As there was no activity on the spoil side of the right-of-way, the backfilled ditchline revegetation efforts were offset approximately 1/3 to the spoil side and 2/3 to the working side of the right-of-way. ... A detailed summary of revegetation by contract section, is provided .... (Au)

The fourth annual monitoring of the revegetation of the Norman Wells to Zama Pipeline was conducted in August, 1987. Total plant cover (the sum of living and grass litter cover) on all seeded areas averaged 66% on the 1984 seeded sites and 55% on the 1985 seeded sites, similar to that recorded the previous year despite warmer and drier than normal growing conditions over much of the pipeline in 1987. Living cover of seeded and native species generally declined. Decreases were most marked on right-of-way seeded in 1984 where living cover declined to 27% from 44% in the previous year. The decline in living cover is attributed to several factors including a drier and warmer growing season and a reduced fertilizer effect. The reduction in living cover is not a concern to site protection i.e. soil erosion, as the protective ground cover has been maintained by a compensating increase in litter cover. Boreal creeping red fescue was the most common seeded species on all seeded areas accompanied on drier sites (back filled mound, coarse soils) by Revenue slender wheatgrass and Sheep fescue. Creeping foxtail was the dominant seeded species on moist sites while Vantage reed canary grass was locally abundant on wet sites. ... (Au)
