The effect of various petroleum products on arctic and subarctic environments is of considerable importance. As part of the research effort into this problem, past fuel spills along the Haines to Fairbanks, Alaska military pipeline were investigated. Since the incorporation of the pipeline in 1956 there have been 40 reported ruptures in the 8-in.-diameter pipe that traverses 626 surface miles. Little new vegetation has grown in the areas of the spills. An inventory of new vegetation or lack of it is reported.
