ANSWER

Protects habitat and reduces human disturbance and development. Legal protection prevents habitat loss from human activities.

Practice questions

A city park has a stream with declining amphibian diversity. Two solutions are proposed. Solution A: Install a vegetated riparian buffer (native shrubs/trees) along both banks. It shades the water, reduces runoff nutrients/sediment, and provides leaf litter and shelter. Constraints/tradeoffs: Requires taking 3 m of lawn on each side; takes 1–2 years for plants to grow; needs weeding early on. Solution B: Add decorative rock lining (riprap) along the banks. It reduces bank erosion quickly. Constraints/tradeoffs: Adds hard surfaces with fewer moist hiding spaces; can increase water temperature by reducing shade; does not reduce fertilizer runoff from lawns. Water testing at a similar stream showed buffers reduced nitrate from 8 mg/L to 3 mg/L and increased dissolved oxygen by 1.5 mg/L; amphibian species count increased from 3 to 5. Riprap reduced bank erosion but nitrate stayed near 8 mg/L; amphibian species count stayed at 3. Which statement about solution effectiveness for biodiversity is supported by evidence and constraints?
