A local authority can approve only one of two building plans. Each plan would use a 2.0 ha area that is currently a habitat for plants and animals.
Ecologists surveyed both areas using the same methods.
| Plan | Number of plant species recorded | Number of animal species recorded | Number of permanent jobs created |
|---|---|---|---|
| P | 28 | 17 | 90 |
| Q | 12 | 9 | 55 |
Suggest which plan the local authority should approve. Use the data to explain your answer.
Suggest one change to either building plan that could reduce its effect on biodiversity. Explain how the change would help.
