Wetlands are also described as staggered zones, Provides a transition between dry land and water bodiesWetlands, Mitsch and Gosselink write, exist « …at the interface between true terrestrial and aquatic systems, making them intrinsically distinct from each other but highly dependent on both. »

What is wetland degradation?

Human activities lead to wetland degradation and loss Change water quality, quantity and flow rate; Increased pollutant inputs; Changed species composition due to disturbance and introduction of alien species.

Why are wetlands so prolific?

Wetlands are High-yielding and biodiversity systems Improve water quality, control erosion, maintain streams, sequester carbon, and provide habitat for at least one-third of threatened and endangered species. Wetlands are important because they: Improve water quality. Provide wildlife habitat.

Are wetlands a staggered zone?

At the landscape level, wetlands are itself a cross between aquatic and terrestrial systems. Their location in landscape depressions makes them receptors for upslope aqueous material, often favoring downstream water quality (Chan et al. 1982, Nichols 1983, Nixon and Lee 1986).

Why are wetlands considered staggered?

Wetlands are staggered zones (transition zones) between terrestrial and aquatic environments. They make up a myriad of terrains that are flooded or saturated with water for part or all of the year and support special vegetation adapted to the conditions.

What are the characteristics of wetlands?

Wetlands must have one or more of the following three attributes: 1) At least periodically, the land primarily supports aquatic plants; 2) The substrate is mainly undrained water-bearing soil; 3) At some point during the growing season each year, the substrate is saturated with water or covered with shallow water.

What are the reasons for wetland degradation?

Wetlands degrade and lose at a greater rate than other ecosystems, mainly due to six drivers: 1) infrastructure development, 2) land conversion, 3) water abstraction, 4) eutrophication and pollution, and 5) excess Fishing and overexploitation, and 6) introduction of invasive species.

How do wetlands work?

When water from river courses or surface runoff enters wetlands, The water spreads out and flows through the lush vegetation. The flow rate is reduced, allowing suspended matter in the water to settle to the wetland surface. The roots of the wetland plants can then bind the accumulated sediment.
