Appendix A. Baywide summary tables for the Narragansett Bay Estuary

              Appendix A. Baywide Summary Tables for the Narragansett Bay Estuary.
Table 1-A. Changes in estuarine emergent wetlands in the Narragansett Bay Estuary: 1950s to 1990s. (Note: Acreage totals reflect acreage affected by each cause so there is double counting of some lost acreage; totals are greater than the actual total loss for these wetlands.)
Table 2-A. Changes in estuarine scrub-shrub wetlands in the Narragansett Bay Estuary: 1950s to 1990s. (Note: Acreage totals reflect acreage affected by each cause so there is double counting of some lost acreage; totals are greater than the actual total loss for these wetlands.)
Table 3-A. Changes in estuarine unconsolidated shores (beaches and tidal flats) in the Narragansett Bay Estuary: 1950s to 1990s. (Note: Acreage totals reflect acreage affected by each cause so there is double counting of some lost acreage; totals are greater than the actual total loss for these wetlands.)
Table 4-A. Changes in vegetated coastal wetlands in the Narragansett Bay Estuary: 1950s to 1990s. (Changes arranged by unique vegetated wetland types; no double counting.)
Table 5-A. Changes in nonvegetated coastal wetlands in the Narragansett Bay Estuary: 1950s to 1990s. (Changes arranged by unique types; no double counting.)
Note: "Coastal processes" includes erosion and accretion related to wave and current action and to sea level changes.Table 1-A. Changes in estuarine emergent wetlands in the Narragansett Bay Estuary: 1950s to 1990s. (Note: Acreage totals reflect acreage affected by each cause so there is double counting of some lost acreage; totals are greater than the actual total loss for these wetlands.)
