Following pipeline construction activities, rights-of-way (ROW) that traverse previously undisturbed landscape units are typically seeded as part of the final reclamation program. Argronomic species are often used in these seed mixtures but there is growing awareness that these species may alter or influence the ecological integrity of the landscape unit disturbed by pipeline construction. We conducted a study on a pipeline ROW to assess the influence agronomic species have on natural secondary succession. The study was also completed to evaluate if there are any ecological impacts or benefits derived from not seeding the disturbance corridor at the end of a reclamation program and if there is significant differences in plant recovery among the three primary work lanes within a pipeline construction ROW. Results from the study indicated there was a significant variation in species richness between seeded and non-seeded areas, indicating that agronomic species pre-empt the reestablishment of a desired endemic community. However, there was not a significant variation between work lanes within the ROW, indicating that typical construction associated with each lane did not influence plant establishment and regeneration.
