Old Roar Gill and Coronation Wood Local Nature Reserve is part of Alexandra Park and is owned and managed by Hastings Borough Council.
Ancient gill woodland within Old Roar Gill, secondary woodland within Coronation Wood.
Many rare and scarce liverworts, mosses and lichens occur within the gill. The regionally scarce toothwort grows here as well as in the rest of Alexandra Park. A rare endemic cranefly, Lipsothrix nervosa, has been found living in the gill as well as the nationally scarce snail Macrogastra rolphii. Spotted flycatchers, grey wagtails and kingfishers can also be found here either breeding or visiting from nearby breeding sites.
