landscaping

Incorrect. Flat surfaces can actually worsen erosion by concentrating water flow in specific areas.

Correct! Vegetation roots hold soil together, preventing it from being washed away.

Incorrect. While barriers can be helpful, they can also disrupt natural drainage patterns.

Incorrect. Vegetation is essential for soil health and erosion control.

Incorrect. While a flower garden can be aesthetically pleasing, it doesn't directly manage stormwater runoff.

Correct! Rain gardens are specifically designed to capture and filter stormwater runoff.

Incorrect. A traditional lawn can contribute to runoff and pollution.

Incorrect. Paved surfaces prevent infiltration and increase stormwater runoff.

Incorrect. Too much sunlight can increase water temperature, harming aquatic life.

Correct! Shade reduces water temperature and improves habitat for aquatic organisms.

Incorrect. Fertilizers can cause algae blooms and deplete oxygen in the water, harming aquatic life.

Incorrect. Invasive species can disrupt native ecosystems and harm aquatic life.

Incorrect. Using fossil fuels increases greenhouse gas emissions, contributing to climate change.

Correct! Trees store carbon and help reduce greenhouse gas emissions, mitigating climate change.

Incorrect. Paved surfaces absorb heat, contributing to the urban heat island effect.

Incorrect. Synthetic fertilizers can contribute to air pollution and climate change.

Incorrect. Rain gardens are a prime example of landscaping for stormwater management.

Incorrect. Green roofs are a great example of landscaping for stormwater management and climate change mitigation.

Correct! Paved parking lots increase runoff and heat absorption, contributing to environmental problems.

Incorrect. Bioswales are a vital part of stormwater management landscaping.

Here's an example of a possible solution:

1. Landscaping Techniques:

• Rain gardens: To capture and filter stormwater runoff, reducing erosion and improving water quality in the nearby stream.
• Native tree planting: To provide shade, reduce water temperature in the stream, and create habitat for wildlife.
• Bioswales: To slow down stormwater flow, filter pollutants, and encourage infiltration.

2. Explanations:

• Rain gardens: These depressions planted with native plants will capture and absorb stormwater runoff, slowing it down and allowing it to soak into the ground. This reduces erosion and prevents polluted water from reaching the nearby stream.
• Native tree planting: Choosing trees native to the semi-arid region will ensure they are well-adapted to the climate. Trees provide shade, which reduces water temperature in the stream, benefiting aquatic life. They also offer food and shelter for wildlife, enhancing biodiversity in the park.
• Bioswales: These shallow, vegetated channels will slow down stormwater runoff, allowing it to filter through the soil and vegetation, removing pollutants before it reaches the stream. This further improves water quality and prevents erosion.
