【 摘 要 】

In 1980, vegetative stress and arboreal mortality in wetland plant communities down-gradient from the F- and H-Area seepage basins were detected using aerial imagery. By 1988, approximately six acres in H-Area and four acres in F-Area had been adversely impacted. Today, wetland plant communities have become well established at the H-Area tree-kill zone. At the FArea tree-kill zone, however, phytotoxicological conditions remain and wetland flora are either nonexistent or marginally surviving. Despite numerous studies and monitoring activities in these areas, none have comprehensively sampled and analyzed the interstitial water and substrate from these areas. The objectives of this investigation were to (1) characterize the pore water and sediment within the tree-kill zones and a control, (2) qualitatively assess the environmental health and recovery of the wetlands, and (3) identify ecological stressors associated with vegetative stress and mortality.
