The objective of this investigation was to delineate and map all wetlands and associated waterways subject to jurisdiction under Section 404 of the Clean Water Act and all wetlands subject to National Park Service (NPS) procedures for implementing Director’s Order #77–1: Wetland Protection Hopewell Furnace National Historic Site (HOFU). This investigation adhered to the U.S Army Corps of Engineers (USACE) Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Eastern Mountains and Piedmont as the primary methodology for making wetland determinations in the field. Under National Park Service D.O. #77.1 guidelines the USACE methodology is appropriate for wetland features possessing vegetation and soils. This inventory only provides data for land-based (palustrine) wetland features, no attempts were made to delineate waterway (riverine systems). A total of 37 palustrine wetlands encompassing 139.63 acres (56.50 ha) of land were identified and delineated from August-October 2014 and October 2015. All of the identified and mapped palustrine wetland systems meet both the U.S. Army Corps of Engineers criteria and the Cowardin et al. (1979) definitions. No new riverine systems were identified and mapped over the course of this investigation within the park boundary. The majority of the larger wetland systems were located in areas previously identified by park staff and USGS/NPS vegetation mapping (i.e. French Creek floodplain), however, a significant number of previously smaller unmapped wetland areas were identified over the course of this investigation including the identification and verification of several vernal pool habitats. The improved boundary information and field delineated wetland mapping will significantly improve the park’s ability to effectively manage, protect, and monitor these unique resources.

The objective of this investigation was to respond to a request for regional assistance for a comprehensive delineation of wetland habitats subject to jurisdiction under Section 404 of the Clean Water Act and all wetlands subject to National Park Service (NPS) procedures for implementing Director’s Order #77–1: Wetland Protection at three wetlands sites located on Thompson, Grape, and Peddocks Islands within Boston Harbor Islands National Park Area (BOHA). This work utilized the U.S Army Corps of Engineers (USACE) Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Northeast and Northcentral Region (January 2012) as the primary methodology for making wetland determinations in the field. A total of 3 palustrine wetlands encompassing 4.50 acres of land were identified and delineated from 14-15 October 2014 within the three islands area (Fig. 1). Observed wetland ecosystems were primarily the following habitats: palustrine, emergent, persistent, (PEM1); palustrine forested, broad leaved deciduous (PFO1); palustrine, unconsolidated bottom, mud (PUB3) These sites were specifically chosen by National Park Service (NPS) and US Forest Service Scientists (USFS) staff as research locations for an invasive plant removal study and this work was performed to identify the regulatory wetland boundaries and facilitate the acquisition of any compliance documents under Section 404 and DO #77.1 purview. All of the identified and mapped palustrine wetland systems encountered during the October 2014 investigation met both the U.S. Army Corps of Engineers criteria and the Cowardin et al. (1979) definitions of wetland habitat. No new riverine wetland systems were identified and mapped over the course of this investigation.

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the Hopedale Hydrologic Restoration (PO-24) project for 2021. This data is used as a basemap land-water classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land loss within their project boundary. To better evaluate the effectiveness of restoration efforts, a land-water classification is performed on specific CWPPRA sites to help assess landscape changes.

Current geospatial features are based on previous 2013 field and post-field work. The following describes the original work and, therefore, applies to these re-created data: The Great Meadows wetlands data were the product of a delineation of wetlands and associated waterways subject to jurisdiction under Section 404 of the Clean Water Act and all wetlands subject to National Park Service (NPS) procedures for implementing Director’s Order #77–1: Wetland Protection within the Great Meadows Study Area was performed from June 10-14, 2013. This work utilized the U.S Army Corps of Engineers (USACE) Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Eastern Mountains and Piedmont Region as the primary methodology for making wetland determinations in the field. One palustrine emergent wetland separated into three cells encompassing (7.56 acres), and two riverine lower perennial/intermittent systems (e.g. Great Meadow Run and Indian Run) encompassing 0.65 acres of land were identified and delineated within the study area (Figure 2). The palustrine, emergent, persistent, habitat (PEM1) exhibited varying degrees of groundwater, floodflows, and past land use influences as evidenced by soil test pits and observations of the plant community throughout the site over the course of the investigation. Wetland-1 consisted of three cells separated by Great Meadows Run: W1 (5.29 acres), W1A (0.88 acres), and W1B (1.39 acres). None of the observed wetland ecosystems meet the PA Title 25, Chapter 105 Exceptional Value (EV) wetland designation standard. However, all of the identified and mapped palustrine wetland systems meet both the U.S. Army Corps of Engineers criteria and the Cowardin et al. (1979) definitions of wetland habitat and would fall under U.S. Army Corps, as well as, National Park Service jurisdiction.
