The benefits of this increased wetland area, perhaps especially for amphibians, may be negated if habitat quality is insufficient to support persistent populations.
The results indicate that there were two primary spatial driving forces of wetland change in Peru's Cordillera Blanca from 1987 to 1995: 1) loss in glacier area was associated with increased wetland area, controlling for other factors; while 2) an increase in mean annual stream discharge in the previous 12 months increased wetland area.
Given the successional patterns of increased wetland species following restoration, we recommend removal of woody invasive species such as L. sinense to prevent their re-establishment followed by long-term monitoring and continued removal (5 7 years) of invasive species to allow native species establishment.
The linear approach calculates increasing wetland retention with increasing upstream catchment area and appears to overestimate nitrogen retention in wetlands located more downstream.
Wetland hydrologic restoration that resulted in an increase in wetland area of between 5 and 20% could potentially increase wetland ecosystem P storage by up to 13 kg P ha−1.
The MeHg concentrations in created wetland invertebrate taxa generally decreased with increasing wetland age, possibly due to a combination of deeper anoxia and less organic matter accumulation in younger wetlands.
Eutrophication of the Baltic Sea has in Sweden led to the initiation of government schemes aiming to increase wetland areas in agricultural regions and thereby reduce nutrient transport to the sea.
"The reports published by Scottish Natural Heritage highlight many of the benefits of this keystone species, such as increasing wetland habitat in the area, boosts to visitors and volunteering in the trial area and the beaver being utilised as an educational opportunity across Scotland".
The retention time of these contaminants (e.g., As) in wetlands could be increased through wetland plants and water flow control, and then it effectively reduces the contaminant diffusion to the surrounding environment via various physical, chemical, and biological processes [ 12].
During the cooling from 1700 to 1300 yr BP, the isthmus area increased, coastal wetlands with lakes and coastal dunes with paleosols were formed, and grassland and swamp landscapes developed.
Carabid beetle diversity significantly increased with wetland restoration and abandonment of farming practices, while the wetland creation did not have a significant effect.
