Tourist numbers at a Northumberland beauty spot could increase if plans to improve access by boat get the go-ahead.

Holy Island is only accessible by a causeway from the mainland at certain times according to the tide patterns.

Now the island's community development officer Rene Richardson is asking islanders for their opinions on a proposed �2m extension to the harbour and pier.

But conservation group English Nature is worried the scheme could disturb local bird life.

Few boats

The island was an early centre of Christianity, keeping the faith alive during a period of invasion.

It has a monastery and castle, and has been a centre for jute processing and fishing, before becoming a leading North East tourist attraction.

At present there are only a handful of visitors to the island, which is also known as Lindisfarne, by boat.

Mrs Richardson said: "There are one or two boats which come from Seahouses.

"But generally, when the causeway cannot be used then the island cannot be accessed.

"However people would be able to visit if we could improve the harbour area."

Bird life

Islanders, most of whom work in the tourist industry, are now being consulted for their views.

Phil Davey, site manager on Holy Island with English Nature, said: "We can see there are benefits to the tourist industry, but we do have some reservations.

"We don't know what the full effects will be on terns and other birds who use the island as a habitat, and which breed on the island."

He said engineering work might alter tide patterns on the mud flats on the island, affecting wildlife.
