Lesley Sneddon, NatureServe 20071231 vector digital data http://www1.usgs.gov/vip/sair/sair.zip doi:10.5066/F7CF9N34 This shapefile is an association-level vegetation map of Saugus Iron Works National Historic Site developed by NatureServe for the National Park Service. The map is based on field work performed in the summers of 2003 and 2004 and a digital orthophoto image flown in early spring 2005. The vegetation communities are crosswalked to the most recent version of the NVCS (October 2007). The map is intended to represent the distribution of association-level vegetation types (association as defined by the National Vegetation Classification System) and anthropogenic covertypes (i.e. areas intenisvely managed or altered by humans) for the Saugus Iron Works National Historic Sire at the time the digital orthophotography was flown (early spring 2005). 20050412 ground condition Complete None planned Saugus Iron Works National Historic Site and environs (Saugus, MA 01906) -71.009635 -71.006021 42.469636 42.466287 National Park Service Theme Category Thesaurus Vegetation ISO 19115 Topic Category biota None Association-level Vegetation Map vegetation map vegetation association National Park Service vegetation classification vegetation alliance vegetation formation National Park System Unit Name Thesaurus Saugus Iron Works National Historic Site National Park System Unit Code Thesaurus SAIR None Saugus Iron Works National Historic Site None Standardized National Vegetation Classification System vegetation classification alliance community association Kingdom Plantae None None Lesley Sneddon NatureServe Senior Regional Ecologist mailing and physical address

Massachusetts Office of Geographic and Environmental Information (MASS GIS) 200606 remote sensing image 5000 digital image (MrSID format) 200504 ground condition SAIR Photomosaic Aerial view of Saugus Iron Works National Historic Site Planning and Scoping: NatureServe ecologist Lesley Sneddon met with Saugus Ironworks National Historical Site staff members Brad Agius and Daniel Noon to review existing information. Brad Agius was nearing completion of an exotic species inventory and had generated a draft vegetation map in the course of his work. Using this baseline data, we conducted a short reconaissance during the scoping meeting and generated a list of NVC associations seen during reconnaisance. NatureServe ecologist Lesley Sneddon determined sample locations and conducted subsequent field work with field assistant LiLi Margolin. Four plots were required to document the vegetation of this small park. An additional field visit was conducted by Lesley Sneddon and NatureServe ecologist Ery Largay to collect additional GPS data and ground photographs. Preliminary Data Collection and Review of Existing Information: Previous studies conducted at Saugus Iron Works National Historic Site were obtained from the park natural resource manager and reviewed for information pertinent to park vegetation. These reports included an invasive plant vegetation map and report conducted by the National Park Service and a preliminary vegetation map and classification for the site. Aerial Photo Acquisition and Processing: High-quality existing photography developed by MassGIS was used as the base for the vegetation map. Photo Interpretation: Using the 2005 SAIR Photomosaic, ecologists at NatureServe developed the final association-level map. The photomosaic was initially examined onscreen in ArcGIS 9.1. Digital topographic quad maps, soil and geology layers were also examined in ArcGIS 9.1. Using information gathered from the photomosaic and the topographic maps as well as vegetation sampling, field reconnaissance, vegetation plot data, and analysis of a USNVC Alliance-level vegetation map and classification for the site, polygons representing different associations and land uses were identified. These polygons were digitized onscreen using ArcGIS 9.1. (For additional details, see final report which is cross-referenced.)
