Morton Marsh was degraded wetland pasture at the time of its acquisition by the Hampshire and Isle of Wight Wildlife Trust in 2016. Since then many hundreds of volunteer hours have helped restore the marshland. Scrub has been cleared, abandoned drains re-established, new ponds established and fencing erected to allow management through grazing. In 2019 a Sand martin nesting bank was constructed with spoil from a large new scrape and a a new viewing platform constructed to offer views across the site.
