24.4.3. Grasslands

Try these first

1. 1.

   What is interception?

   Hint

   Think about the role of plants in capturing rainfall.

2. 2.

   What percentage of precipitation do grasslands typically intercept?

   Hint

   Compare this with forests.

3. 3.

   What is the typical interception percentage for grasslands?

   • 0%-5%
   • 5%-10%
   • 10%-20%

   Hint

   Think about how dense the vegetation is.

4. 4.

   True or False: Interception in grasslands increases groundwater recharge.

   • True
   • False

   Hint

   Consider the effect of more rain reaching the ground.

5. 5.

   Examine how introducing a wider variety of vegetation types in grassland could influence interception rates. Provide specific examples.

   Hint

   Consider the characteristics of different plants and their water-holding capabilities.

6. 6.

   If a grassland area receives 600 mm of rainfall with an interception rate of 10%, calculate the amount of water reaching the ground. Discuss the implications of this on local ecosystems.

   Hint

   Multiplication and subtraction will help you find the exact figures.
