UK experts have recommended Jersey introduce a permit system on its offshore reefs, which would pay for wardens.
It is one of several suggestions to manage the number of tourists visiting the Ecrehous and the Minquiers in the summer.
In recent years, conservationists have called for wardens to start patrolling the offshore reefs because of worries that too many visitors could disturb wildlife there.
A new report from an architect studying Jersey's future planning policies has highlighted the importance of protecting the special qualities of the Ecrehous and the Minquiers.
It talked about limiting the number of boats that can moor there, or introducing a quota system for private companies that take people on tours of the reefs.
It suggested the permit system would pay seasonal wardens to patrol the reefs or an alternative source of funding would be asking people who run tours to pay a charge for a set number of visitors.
It also said any effort to manage visitor numbers needed to take into account the unique character of the reefs without cluttering them with signs or artificial paths.Copyright: BBC
