Two coastal reserves offer visitors the chance to see nesting seabirds. Both reserves monitored 100 nests during one breeding season.
| Visitor-management approach | Number of visitors during the season | Number of monitored nests disturbed |
|---|---|---|
| Visitors use marked paths and hides | 12 000 | 8 |
| Visitors can walk freely near nesting areas | 7 000 | 24 |
Compare the evidence for the two visitor-management approaches and justify which approach should be used to conserve the seabirds.
