U.S. Fish & Wildlife Servicehttps://www.tidalmarshbirds.org/ SHARP - With partners in governmental agencies, conservation non-profits, academic organizations, and private citizens, we support the science behind tidal marsh bird conservation. We answer the questions needed to prevent tidal marsh birds and their wetland habitats from vanishing. We ask that you please acknowledge SHARP in all uses of these data, and if your use represents a substantial portion of a particular publication, please consider reaching out to the SHARP Principal Investigators for our greater involvement and potential authorship. 1994 - 2012 Tidal marsh bird survey database (max counts) SHARP Bird Surveys (1994-2012) - Public Release: 22Oct2015 (417 downloads) ( data, metadata, and database contact information ) This database contains compiled data from 11 contributing organizations (see metadata) that conducted avian point counts between 1994 - 2012 within wetlands designated as E2EM (Estuarine Emergent Wetland - i.e., tidal salt marsh) by the National Wetland Inventory. Each row indicates the maximum count of individuals of each species detected at a point for a particular year. Detections for our five focal species (Saltmarsh Sparrow, Seaside Sparrow, Nelson's Sparrow, Willet, and Clapper Rail) are included in this database.
