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 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 within the floodplain of Blow-Me-Down-Creek upstream and within the immediate area surrounding Blow-Me-Down-Dam on Saint Gaudens National Historic Site (SAGA) lands. 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 7.23 acres of land were identified and delineated from 22 -25 September 2014 within the study area (Fig. 1). Observed wetland habitats were primarily a combination of palustrine, emergent, persistent, habitats (PEM1) and scrub-shrub (PSS) habitats that exhibited extensive soil saturation at the time of the investigation. 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. No new riverine wetland systems were identified and mapped over the course of this investigation.

The objective of this investigation was to respond to a request for regional assistance for a comprehensive 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 summit area of Allegheny Portage Railroad National Historic Site (ALPO). 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. A total of 7 palustrine wetlands encompassing 4.43 acres of land were identified and delineated from 17 -20 September 2012 within the ALPO summit area (see associated geodatabase). The majority of the wetland habitats observed within the ALPO study area were palustrine, emergent, persistent, habitats (PEM1) with varying degrees of groundwater influence. 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. No new riverine wetland systems were identified and mapped over the course of this investigation; however, five seeps and their associated drainages were identified in close proximity to one of the proposed PADEP borehole sites.

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 purpose of this project was to map the wetlands across New South Wales. Wetlands were identified using a combination of classification of spectral classes of Landsat MSS and TM imagery and ancillary wetland information to create information classes of broad wetland groups (floodplain wetlands, freshwater lakes, saline lakes, reservoirs, estuarine wetlands and coastal lagoons and lakes). The data will then be used to assess the wetland resource in each catchment. For more details refer to: Kingsford, R., Brandis, K., Thomas, R., Crighton, P., Knowles, E. and Gale, E., 2004.
