In its first six months of opening the Teesside Wildlife Centre has had more than 50,000 visitors, a great deal more than the predicted 35,000 for the whole year. The centre is helping to boost visitor numbers at other Teesside attractions as well, such as the Transporter Bridge and the Teesmouth National Nature Reserve. The 1,000 acre reserve was developed by the Royal Society for the Protection of Birds and the Teesside Environmental Trust.
