A+ QUESTIONS AND ANSWERS ON
WETLANDS AND THEIR IMPORTANCE.
What is a wetland?
Wetlands are ecosystems that are saturated with water either
permanently or seasonally. They are important because they provide
habitat for diverse species, improve water quality, control flooding,
and act as carbon sinks to combat climate change.
What are the main types of wetlands?
The main types of wetlands are marshes, swamps, bogs, and fens,
each distinguished by water source, vegetation, and soil type.
How do wetlands help in flood control?
Wetlands act as natural sponges by absorbing and storing excess
rainwater or river overflow, which reduces the risk of flooding in
nearby areas.
What role do wetlands play in improving water quality?
Wetlands filter pollutants, sediments, and nutrients from surface
water through the natural processes of absorption, sedimentation, and
microbial activity.
Which species are commonly found in wetlands?
Wetlands are home to various species, including amphibians like
frogs, birds such as herons, fish like catfish, mammals like beavers,
and plants such as cattails and sedges.
What are the primary threats to wetlands?
The main threats to wetlands include drainage for agriculture, urban
development, pollution, invasive species, and climate change.
,How do wetlands contribute to the global carbon cycle?
Wetlands store large amounts of carbon in their soils and vegetation,
reducing greenhouse gas concentrations in the atmosphere.
Why are wetlands referred to as biodiversity hotspots?
Wetlands support a high diversity of plant and animal life due to
their unique hydrology and nutrient-rich environments.
What is peat, and how is it related to wetlands?
Peat is a type of soil made of partially decomposed organic material
that accumulates in waterlogged conditions, often found in wetlands
like bogs.
How do wetlands support migratory birds?
Wetlands provide resting, feeding, and breeding grounds for
migratory birds, which rely on these habitats during their seasonal
journeys.
What is the Ramsar Convention on Wetlands?
The Ramsar Convention is an international treaty signed in 1971 to
protect and sustainably manage wetlands of international
importance.
How do human activities affect wetland ecosystems?
Activities like land reclamation, deforestation, industrial pollution,
and excessive water extraction degrade wetland ecosystems and reduce
their ecological functions.
What are the ecological services provided by wetlands?
Wetlands provide services such as flood control, water purification,
climate regulation, erosion prevention, and habitat for wildlife.
How do invasive species impact wetlands?
Invasive species outcompete native plants and animals, disrupt food
, chains, and alter the physical structure and function of wetland
ecosystems.
What steps can be taken to protect wetlands?
Protection efforts include establishing conservation areas, enforcing
environmental laws, restoring degraded wetlands, controlling
pollution, and raising public awareness.
Why are wetlands important for local communities?
Wetlands provide resources like fish, water, and medicinal plants,
support livelihoods, and offer cultural and recreational opportunities
for local communities.
How does climate change threaten wetlands?
Rising temperatures, sea-level rise, and altered rainfall patterns can
lead to wetland drying, saltwater intrusion, and habitat loss.
What is wetland restoration, and why is it necessary?
Wetland restoration involves actions to repair degraded wetlands
to regain their ecological functions. It is necessary to combat
biodiversity loss, improve water quality, and enhance resilience
to climate change.
What is the difference between freshwater and saltwater
wetlands?
Freshwater wetlands are found inland and are fed by rivers,
lakes, or precipitation, while saltwater wetlands are located near
coasts and are influenced by tides and saline waters.
How do wetlands contribute to erosion control?
Wetlands reduce erosion by stabilizing soil with their dense root
systems and by buffering wave and wind energy along coastlines
and riverbanks.
