6 Introduction • identify those areas in which knowledge is lacking • establish a framework and impetus for future study • facilitate natural resource-based conservation and development planning The ultimate goal of producing the NRIA is the maintenance of a healthy, functioning environment, and the preservation of Guilford’s quality of life. It is the Conservation Commission’s role to assist the Town in realizing these goals. Who should use this document? Town Staff Town Boards and Commissions Non-governmental organizations Developers Landowners Guilford Land Conservation Trust Shoreline Outdoor Education Center Teachers and students Tourists and visitors How is this document organized? The NRIA is divided into two documents: descriptive text and a separate Map Atlas (11x17 inches) that illustrates spatial data for each resource and combined data layers to show important relationships among them. How were the maps compiled? The software in Guilford’s Geographic Information Systems (GIS) assembles, stores, and manipulates spatial data and can help users analyze data for conservation and planning purposes. The GIS is located in the office of the Town Environmental Planner. What is the Geographic Information System (GIS)? GIS software assembles, stores, and manipulates spatial data and can help users analyze data for conservation and planning purposes. The GIS located in the office of the Town Environmental Planner was used to produce most of the natural resource maps found in the Atlas. Many of the data layers used here were acquired from agencies (e.g, DEP, NRCS), while others were created specifically for this project. How will this NRIA be updated and revised? One of the goals of the NRIAC is to provide a structure around which future investigators can organize incoming data and more detailed studies. This NRIA therefore includes a section in which known gaps in the data are listed on page 11, with suggestions about areas in which future efforts should be focused. The Conservation Commission will be responsible for organizing further studies, verifying information in the field (“ground-truthing”), and describing any changes in the resources over time. Besides its paper form, this document will be available electronically. As new data is gathered, the GIS can update the maps found in this document. The Town website will be available to provide easy access to the NRIA by both the public and town officials. New or corrected information will promptly be made available to all land use agencies in Guilford. Natural Resource Inventory and Assessment Town of Guilford, CT
