The number of locals and holiday-makers visiting the site in Trinity has fallen year on year, which is being put down to a decline in tourism.

The trust said it hoped to attract more corporate sponsors and staging new events, including starting new funding schemes and introducing a new logo.

The Trust said it was also starting new marketing campaigns.

There are also plans to encourage more business-use of the site and build more open air enclosures, like the bird aviary.

Meanwhile, people in the south coast of England will be targeted in a new marketing campaign.
