||An approach is presented that could facilitate disturbed tundra revegetation and monitoring in Alaska North Slope Oil Fields. Experiments were conducted on an abandoned drilling pad where the gravel was removed to a thin layer (Ca. 20 cm) above tundra grade and mixed with underlying compacted original sod. Intact plugs 13.3 cm in diameter were transplanted from a donor plot into the thin gravel in treatments with and without mini greenhouses covering single plugs and double plugs. At the end of the first growth season, the greenhouse air temperature (in aggregate thawing degree C days) was elevated 68% and the greenhouse soil temperature was elevated 17% above the ambient air and soil temperatures, respectively. Two independent methods were used for estimating plug growth. Visual cover estimation showed that double plugs with greenhouse produced cover values significantly greater than single plugs. Radiometry measurements developed and modeled to predict plug canopy dry weight showed that the dry weight for all treatments except double plugs with greenhouse fall within ranges of samples taken from stressed areas in the native tundra.
