Alverstone Marshes

Alverstone Marshes is a 83.8 hectare biological Site of Special Scientific Interest on the Isle of Wight, notified in 1951.
The Alverstone Marshes are the site of a wetland restoration project by the Royal Society for the Protection of Birds. It is also noted for water voles.

On August 5th 2005, the Island 2000 Trust began removing soil to make room for a pond for local wildlife such as water voles and dragon flies. At the time, they had checked for any archaeology spots around the area and found nothing. During the excavations, they started coming across metal teeth crunched onto the cobbled surface of an ancient road, possibly Roman. If it was true, this would have been the first ever discovered on the island. As they continued more and more excavating, they came across human artefacts and biological records.  If you’d like to know more about this topic, click Source 2:
