National Vegetation Classification (NVC) map for Fish Springs National Wildlife Refuge. NVC provides a standardized hierarchical approach to classifying vegetation and this standard is being implemented by federal, state, tribal, and non-profit organizations throughout the United States. In order to maximize the efficiency and usefulness of the Refuges mapping project in support of management needs, mapping was completed to the NVC Alliance level (dominant species). Mapping took place in the following 8 stages: (1) Site visits were conducted and 16 NVC Alliances that best fit dominate vegetation cover at Fish Springs NWR were selected; (2) 14 Project Codes (PCs) were defined to meet management’s mapping needs in conditions that do not meet a published NVC Alliance; (3) Prior to heading into the field, an initial digitization effort was completed where recognizable stands of dominant vegetation were digitized using a 2006 NAIP aerial image; (4) The initial digitizing effort was improved upon through a ground-truthing process in the field using established mapping standards and diagnostic criteria; (5) Once all vegetation mapping across the Refuge was completed, a re-verification effort in the field was conducted, and corrections were made where needed; (6) A digital editing review was completed to identify any potential digital mapping errors, and if needed sites were revisited; (7) A stratified random sampling method was utilized to assess map accuracy, and any identified errors were corrected; (8) The baseline NVC vegetation map (alliance level) was then utilized to create additional classification categories of broader habitat types and water regimes.Of the available 30 mapping categories (Alliances and PCs) established for the mapping effort, 28 were utilized within the final NVC vegetation map. A total of 819 randomly selected assessment points were visited for the final accuracy assessment, resulting in a final map accuracy of 96.7%.
