Threats to Wetlands

Front

What is degradation in the context of wetlands?

Back

Degradation refers to the deterioration of wetland quality due to factors like sedimentation, pollution, and development, leading to loss of biodiversity and ecosystem services.

Front

What are dams and their purpose in wetland management?

Back

Dams are structures built to hold and release water, creating reservoirs that can manage water flow and sometimes generate power, impacting wetland ecosystems.

Front

What are invasive species?

Back

Invasive species are non-native organisms that disrupt local ecosystems, often outcompeting native species and altering habitat conditions.

Front

Name three invasive species that negatively affect wetlands.

Back

Saltcedar, Nutria, and Beavers are all invasive species that can harm wetland ecosystems.

Front

How does building on wetlands affect hurricane impact?

Back

Building on wetlands can increase the devastation from hurricanes by reducing natural barriers that absorb storm surges and flooding.

Front

What percentage of natural wetlands have been lost?

Back

Approximately 50% of natural wetlands have been lost due to human activities and development.

Front

What is point source pollution?

Back

Point source pollution refers to contaminants that enter a water body from a single, identifiable source, such as a pipe or ditch.

Front

What is the role of wetlands in flood control?

Back

Wetlands act as natural sponges, absorbing excess water during floods and releasing it slowly, helping to mitigate flood impacts.

Front

What is agricultural runoff and its impact on wetlands?

Back

Agricultural runoff is water that carries fertilizers, pesticides, and sediments from farmland into nearby water bodies, leading to pollution and degradation of wetlands.

Front

Define sedimentation in the context of wetlands.

Back

Sedimentation is the process by which particles settle out of water, often leading to the filling in of wetlands and loss of habitat.
