A forest reserve is near several villages. A community cooperative runs low-impact river trips and guesthouses for visitors. The table shows the income local residents received from these activities and the number of illegal hunting incidents recorded in three different years.
| Year | Income received by local residents during the year (£) | Illegal hunting incidents recorded during the year |
|---|---|---|
| Year before the scheme began | 0 | 24 |
| First year of the scheme | 38 000 | 15 |
| Third year of the scheme | 74 000 | 6 |
Explain how the data support the view that the scheme may have helped to reduce illegal hunting, and predict what could happen to hunting if local residents stopped receiving income from the scheme.
