The Natural Resource Publication series addresses natural resource topics that are of interest and applicability to a broad readership in the National Park Service and to others in the management of natural resources, including the scientific community, the public, and the NPS conservation and environmental constituencies. Manuscripts are peer-reviewed to ensure that the information is scientifically credible, technically accurate, appropriately written for the intended audience, and is designed and published in a professional manner.

"The Northern Colorado Plateau Inventory and Monitoring Network worked with the support of the U.S. Geological Survgey - National Park Service Vegetation Mapping Program to describe and map vegetation at Golden Spike National Historic Site (GOSP, or NHS). ... Analysis of the classification plot data revealed 18 National Vegetaition Classification (NVC) plant associations or park special vegetation types within GOSP. Several additional plant associations for which map units were developed were not sampled with classification plots, but were instead documented by extensive field notes and photographs" -- p. xiii.

Hubbell Trading Post National Historic Site (HUTR) covers approximately 65 ha (160 acres) in northeastern Arizona, and lies wholly within the borders of the Navajo Nation. The vegetation found at HUTR consists of approximately 184 species of vascular plants, representing 48 families, in a limited set of communities. This mapping project is part of the National Park Service's National Inventory and Monitoring (I&M) Program, and has been designed to provide core, or “baseline” information that park managers need to effectively manage and protect park resources.

This project documents the vegetation associations of Allegheny Portage Railroad National Historic Site based on 2003 aerial photography and 2005 field sampling, and completes one of 12 basic inventory data sets for the park.

NatureServe contracted with the New Hampshire Natural Heritage Bureau (NH Heritage) to conduct a survey and produce a map of the vegetation of Saint-Gaudens National Historic Site. NatureServe ecologists planned the sampling, oversaw the field effort, and integrated plot and accuracy assessment data and field information into the U.S. National Vegetation Classification (USNVC) to produce a standardized product for the National Park Service. The purpose of this project was to produce a standardized map and classification of the vegetation communities and land cover of the Saint-Gaudens National Historic Site and to provide thorough baseline data on the park's vegetation.

This document details the vegetation classification and mapping which was completed for Saugus Iron Works National Historic Site, It includes a current digital geospatial vegetation database for the park. Six vegetation associations occurred within the park, and these were identified and described in detail. The associations were Northeastern Modified Successional Forest, Reed Canarygrass Eastern Marsh, Reed-grass Tidal Marsh, Cattail Brackish Tidal Marsh, Skunk-cabbage - Orange Jewelweed Seep, and Central Atlantic Freshwater Subtidal River Bed.
