Psuty NP, Menke C, Habeck A, Raphael J. 2023. Shoreline position monitoring at Fire Island National Seashore: 2017–2022 and 2007–2022 trend report. Natural Resource Report. NPS/NCBN/NRR—2023/2531. National Park Service. Fort Collins, Colorado. https://doi.org/10.36967/2299483
The Shoreline Position Trend Report summarizes the results of data collected in 2017 through 2022 along the ocean-facing shoreline of Fire Island National Seashore in addition to data collected in 2007 through 2017. Data sets include a spatial depiction of annual shoreline position as well as statistical analysis describing annual and 5-year, and 15-year changes, all following the model presented in Psuty et al. (2022b). Generally, the largest vectors of shoreline position change were produced by natural events such as storms and by human-induced cultural events such as beach nourishment or dredging. The most mobile portion of shoreline was at Democrat Point. At this site, the shoreline downdrift of the jetty was extending westward and was cut back due to dredging. The other portion of the shoreline with the largest vectors of change was in the Otis Pike Fire Island High Dune Wilderness. The NPS lands and community lands had different rates of change, with higher rates of erosion along the western portion of Fire Island. Beach nourishment episodes at Smith Point County Park and within community lands tempered the rates of inland displacement. This is the third trend report for Fire Island National Seashore produced for the Northeast Coastal and Barrier Network in accordance with the protocol for shoreline position monitoring. The first trend report covered from 2007 through 2012 (Psuty et al. 2017), the second trend report covered 2012 through 2017 (Psuty et al. 2018). Generally, the most recent trend is similar to the earlier reporting periods, with storminess and anthropogenic influences affecting shoreline position.
