I popped over to Brownsea in late Feb to do a high tide count for the Dorset Wildlife Trust. The island is closed to the public for the Winter. However, I've been asked if I can do a few high tide counts over the Winter, which allows the DWT wardens to get on with other conservation activities on the reserve. There was a reasonable selection of Waders and Wildfowl species on the lagoon. As the tide was just switching into a neap cycle, the numbers weren't as impressive as they would have been had it been a Spring high tide.
The highlight of the visit was seeing the new Tern islands that have been created. The DWT wardens, along with DWT volunteers and an external contractor have created four new Tern islands, which are looking really good. The new islands have their top stones on and the plan this season is to leave them unfenced to see how much disturbance they get from the Sika Deer. In previous years, the Sika Deer have tried to get onto the islands to eat the vegetation, which is a risk to the nest Terns and Gulls on the unfenced islands. Hopefully, with the new islands being new and unvegetated, the Sika Deer won't be a problem on the new islands this season. The Black-headed Gulls and Sandwich Terns are comfortable with being fenced in, however, the Common Terns prefer unfenced islands.
The other three new islands: It will be interesting to watch the interest in these new islands over the next few weeks
There are already signs and noises of Spring with quite a few Black-headed Gulls investigating the old islands.
Black-headed Gull: The DWT team have also turned over the stones on the old islands and the Black-headed Gulls are showing a lot of interest in these islands
