Since 1996 Gift to Nature has worked with landowners: the Isle of Wight Council; Environment Agency; and Natural England on the management and conservation of the 200ha Alverstone Marshes SSSI. The pre-1981 SSSI boundary extended to the Wetland Walk. There are two particular achievements worthy of note. The first is the successful five year campaign with Natural England to raise the official status of the overall SSSI from ‘unfavourable declining’ to ‘favourable improving’ through targeted habitat restoration work with 5 landowners. The second is the extraordinary archaeological and palaeoecological find made during Gift to Nature works at Alverstone bridge in 2005. This is still being investigated by the Museum of London and the IW archaeology team but is a nationally significant find spanning Roman to Medieval artefacts and structures linked to a tidal wharf, a mill and a river crossing.
