Drainage and a downward trend in rainfall for the past 15 yrs have stressed ecosystems causing a decline in wading birds. Simulations suggest that drainage more than decline In rainfall was responsible for the decrease in storks. Wood Storks have shown resiliency in adapting to the drained conditions, finding new feeding areas such as the marshes at Lake Okeechobee. Plans to raise lake regulation levels will eliminate half this area. Because of the topography of southwest Florida, present drainage has greatly decreased the area flooded but has only slightly decreased the range of fluctuation. Therefore, a wetlands ecosystem dependent on oscillation continues to operate. If, however, the mean water level is further lowered, the fluctuation of water area may be drastically reduced and the ecosystem seriously disrupted. Chairman
