Which of the following is a way to potentially eliminate one of the greatest threats to the world's mangrove wetlands?
increase desalination to reduce the effects of prolonged drought in mangroves
integrate ecologically sound shrimp aquaculture practices with mangrove management
construct dams in mangroves to increase sediment load and decrease pollution
employ irrigation methods to address potential desertification of mangrove habitats
Which of the following is most likely to result from destruction of wetlands surrounding a river?
a decreased sediment load in the river
a decreased level of pollutants such as nitrates in the river
an increased diversity of aquatic species in the river
an increased level of oxygen in the river
e. an increased frequency of flooding of the river valley
Which of the following approaches would best decrease the impact of frequent flooding in a community that is subject to the hazard of flooding?
Construct wetland areas near the rivers and streams.
Remove forested areas around all streams and rivers and change land use to agriculture.
Increase the height of natural levees downstream from the community.
Encourage developers to build housing developments on the floodplain.
What is a Wetland?
Areas where water covers soil and doesn't drain either all year or certain times
Areas where soil covers water all year
Similar to a tsunami; giant waves caused by natural disasters
An area where water isn't present for a long time to the point it looks like a desert
Which of the following statements best describes how the Clean Water Act legislation aims to protect wetlands from being lost?
The Clean Water Act bans the draining of wetlands over five acres in size.
The Clean Water Act requires wetlands to be constructed to mitigate the effect of newly drained wetlands.
The Clean Water Act establishes standards for the quality of surface waters that must be continually monitored and reported.
The Clean Water Act prohibits the use of wetlands for development and construction.
What is a Mangrove?
A descendant from the lion species and are very similar in looks except they are herbivores
Tropical plants that usually reside in tropical areas but are heavily declining in numbers due to loose, wet soils, salt water, and being submerged
An herbivore that is descended from the koala and reside in warmer climates
Tropical plants that reside near the coast which can tolerate loose, wet soils, salt water and being submerged
How is human development a threat to wetlands?
As humans continue to build and develop buildings it will allow biodiversity to increase in cities and human populations and wetlands will be deserted
As humans continue to build and develop buildings it allows animal populations to blend among humans leaving the wetlands all alone
As humans construct buildings this can lead to changes in water quality, flow rates, and pollutant inputs
As humans build for development it increases the amount of fertilizer runoff that goes into the wetlands
How are fish impacted in wetlands?
The fish species increase because there is huge amounts of water in wetlands
Lots of fishermen will find these spots attractive and overfish in these areas
Lots of fish will compete with each other within wetlands because they like this area and don't wanna share
Fish depend on these wetlands, wetlands serve as a food base, shelter, spawning and nursery areas, and for water filtration.
What Climates do Mangroves reside in?
Tropical
Semi-Arid
Arid
Dry
Recall The National Everglades Park case study, what is one way the wetlands negatively impacted the water surrounding it?
Lots of oxygen accumulated within the wetland and caused soil degradation
The Declining of wetland populations has disrupted the ecosystem and its services
The enormous amount of phosphorus that has accumulated within the wetland has degraded the water quality
Algae bloom has increased
