The fоllоwing is sоme informаtion аnd finding on The Stаte on California’s salt water marshes. Review this information below before answering the question(s) on California’s wetlands quality. 85% of the State’s salt marshes were in good to very good health; 35% of salt marsh acreage reflected very good hydrology and marsh plant community structure; 65% had large, intact buffers. Salt marsh health generally declined from Northern to Southern California, consistent with a trend in increasing urbanization. Dikes and levees were among the most frequent and most severe physical stressors. California has 2.9 million acres of wetlands. Estimates of total historical wetland loss vary for California. Some regional studies have reported loss rates up to 90%. Some wetland types, such as vernal pools, riparian habitat, and coastal wetlands have experienced disproportionately higher rates of loss. Wetland loss has occurred as land was converted from natural habitat to urban and agricultural land uses. • California has made substantial progress over the last 10 years in identifying, acquiring, restoring, and enhancing wetlands As of this study, approximately how many million acres of wetlands in California are in good to very good health?
