How is wetland health measured?

Wetland health or condition can be determined by observing the wetland’s structure (its parts) and function (what it’s doing). Examples of wetland structure include: water quality soil condition geology hydrology topography morphology carrying capacity species composition food web support and nutrient content.

How do wetlands help reduce the damage caused by hurricanes?

Wetlands can help reduce the damage caused by hurricanes by protecting coasts from storm surges. Storm surges are an effect from hurricanes.

Are wetlands rich in nutrients?

When these plants die a large portion of the nutrients return to the water and sediment from decaying plant material. During this period (in late fall and early spring) wetlands serve as a nutrient source when water flows from the wetlands to ecosystems downstream (Figure 2).

How the loss of wetlands leads to environmental and ecological problems?

The loss of wetlands leads to environmental and ecological problems which have a direct impact on the socio-economic benefits of the associated populace. Serious consequences including increased flooding species decline deformity or extinction and decline in water quality could result.

What causes wetland pollution?

These alterations can be the results of: deposition of fill material draining dredging and channelization diking and damming diversion of flow and addition of impervious surfaces in the watershed which increases water and pollutant runoff into wetlands.
