McKinney NWR Management Units ...................... 7 PURPOSE AND NEED INTRODUCTION The United States Fish and Wildlife Service (the Service, FWS) requires that every area with burnable vegetation has an approved fire management plan (FMP) that describes actions to prepare for and respond to a wildfire (fire suppression); plans for and manages vegetation by management actions, including prescribed fire; and completes other fire management business in accordance with an approved Comprehensive Conservation Plan (CCP). The Service has prepared this Spatial Fire Management Plan and Environmental Assessment (SFMP and EA) for the Stewart B. McKinney National Wildlife Refuge (NWR) located along the Long Island Sound of Connecticut to continue to protect natural and cultural resources, the public, FWS employees and facilities, and comply with Agency and policy direction. This FMP and EA has been prepared in accordance with the National Environmental Policy Act (NEPA), as amended [42 United States Code (USC.) 4332(2) (C)]; the implementing regulations of the Council on Environmental Quality (CEQ) [40 Code of Federal Regulations (CFR) 1500-1508.9]; the U.S. Department of the Interior (USDI) NEPA regulations (43 CFR Part 46); and Service policies 30 AM 2-3, 550 FW 3, 602 FW 1-3, and the handbook for National Wildlife Refuges (FWS 2014). The FMP must meet agency policy and direction of the: • National Fire Plan: A Collaborative Approach for Reducing Wildland Fire Risks to Communities and the Environment: 10-Year Comprehensive Strategy (USDI and U.S. Department of Agriculture [USDA] 2001a) • Managing Impacts of Wildfires on Communities and the Environment and Protecting People and Sustaining Resources in Fire Adapted Ecosystems – A Cohesive Strategy (also known as the National Fire Plan) (USDI and USDA 2001b) • A Collaborative Approach for Reducing Wildland Fire Risks to Communities and the Environment: 10-Year Comprehensive Strategy Implementation Plan (an adjunct to the National Fire Plan 2001) (USDI and USDA 2006) • Guidance for Implementation of Federal Wildland Fire Management Policy (February 2009) • Federal Land Assistance, Management and Enhancement Act of 2009 (National Cohesive Strategy) Among other policies, the FMP must provide for firefighter and public safety while it adheres to the USDI policy (620 DM 1) by giving full consideration to the use of wildland fire as a natural process during the fire management planning process. The Service intends to use the SFMP format to plan and implement fire suppression needs for the refuge in place of the traditional narrative FMP format. This type of planning is a new concept in the United States. Spatial (also referred to as geospatial) refers to a topographically accurate representation of landscape features presented in digital or hardcopy. Fundamentally, geospatial planning moves a lot of information from text descriptions in documents to geospatial representation on maps. The products are a combination of text documents and mapsheets, with the text documents being greatly reduced in volume from the present size. The SFMP provides advantages to the managers, fire fighters, all risk responders, and planners that rely on the Purpose and Need 1 critical information that is readily accessible in any number of mapsheets, spatially viewed, with limited text to digest. A mapsheet is a collection of one or more maps, tables, and other information on a single page. The following are important reasons to use the SFMP concept: • Critical information is more easily accessible to users, management, incident teams, stakeholders, and the public. • The information is updated more easily and kept current as conditions change (for example, fuels projects completed or as wildfires occur). • There is an overall reduction in the cost and time to produce and update documents. • There is a reduced reliance on large, dense text documents that may be difficult to use and reference. • The geospatially represented information from fire management planning becomes straightforward to integrate with other evolving spatially based systems such as the Wildfire Decision Support System and National Fire Plan Operations and Reporting System (NFPORS). The planning effort will take significant core data from the FWS databases and geographic information systems to create geospatial representations in a coherent map set
