Vegetation Monitoring Results <br />A vegetation survey is undertaken annually on the NS lease to collect data from <br />reclaimed land to monitor and evaluate the success of revegetation efforts. <br />In 2023 the vegetation survey focused on six reclaimed pad sites in final reclamation <br />status, and four additional undisturbed areas for comparison purposes. <br />Five of the six locations studied are former core holes; BG-8, G, MMC-IRI-3, T, and U <br />that are currently undergoing final reclamation. One former production well P&A <br />location the 93-2M is in final reclamation status. <br />The continued dry conditions that occurred during the growing season in 2023 resulted <br />in only minimal changes to the total vegetation cover and composition of desirable plant <br />species as compared to the values measured in 2022 or with comparison to the <br />undisturbed control areas. All of the sites showed improvement in the study. Pad G <br />met the criteria for successful reclamation. Pat T and Pad U both have increases in <br />Non-Native Invasive species that may require remediation in 2024 and possible <br />reseeding. None of the above mentioned reclaimed sites achieved successful <br />reclamation criteria in 2023.
