Hofler Property- Adaptive Management Plan (05/28/20)
Albemarle Restorations, LLC, is proposing the following Adaptive Management Plan (AMP) for the Hofler
Property (DMS Contract #004628) for the North Carolina Division of Mitigation Services (DMS) and
Interagency Review Team (IRT) review and comment. This AMP is being submitted to conduct work on
site to improve planted vegetation performance and consists of the following five (5) requests:
1. Conduct tree planting this winter (20/21) using bare root and/or containerized (based on
availability) Bald cypress at a rate of 200 trees/ac or more to bring the stocking up to required
levels in underperforming areas. These areas consist of the lower half of the project site,
represented by plots 1, 2 and 11-18, as identified in the MY5 Monitoring Report (pg. 11).
Additional tree planting across the entire site may occur based on seedling availability. Bald
cypress was chosen because of its ability to grow in wet conditions, tolerance to competition,
and past performance on site.
2. Conduct 10-15 additional vegetation plot (1/100th ac) surveys across the site this year. These will
be randomly located outside of existing survey locations to better assess tree height, density,
and survivorship.
3. Continue vegetation monitoring for additional two (2) years (MY8 & MY9) to ensure survivability
and achievement of success criteria.
4. Release from future Wetland Hydrology Performance Standards by the IRT. The approved
Hofler Mitigation Plan Credit Release Schedule for Forested Wetlands (pg. 21) allows for the
discontinuance of hydrologic monitoring after the 5th year provided the performance standards
have been met. As of MY5, the Hofler project has met or exceeded its hydrologic performance
standards every year.
5. Release from the 10 feet in average height by MY 7 vegetative performance standard (pg. 27).
The Hofler project has exceeded its average annual rainfall amounts during the monitoring
period each year. Years 2 (2016) and 3 (2017) were especially hard on planted stock, with above
average rainfall amounts during the growing season (April -mid Nov) of +16.54 and +14.64,
respectively. This excessive rainfall restricted our efforts at herbaceous weed control and led to
supplemental planting being conducted between MY 2 and 3 (Feb. 2017). Unfortunately, site
conditions have improved only slightly as rainfall continues to exceed normal expectations.
