Subtask 4.F: Post Construction Monitoring

Description: Dune planting success on will be evaluated after 6 months to assess whether at least 85% of the initial planting is surviving and to document how the vegetation is colonizing outside the initial planting limits.

Field measurements will be conducted along transects spaced approximately every 1,000 feet between the planting limits. The survey methodology shall consist of stretching a 100-foot long tape along either a north or east axis from the seaward edge of the vegetation to a point located along the landward edge of the installed dune plantings. The survey shall begin at the zero mark and proceed along recording data at every foot mark making a visual observation 90 degrees perpendicular to the tape from above (101 observations per transect). Data recorded shall include plant species or bare earth present, and whether the mark fell on the plant itself or a stem of it.

Any stems not attached to a plant that are at the survey mark shall be considered as bare earth.

Additionally, dead plants shall not be counted and considered as bare earth if present under the survey mark. The results of the survey will be summarized in a report and provided to the DEP Project Manager

Deliverables: A summary report of the vegetation planting will be provided to the DEP Project Manager in PDF format.
