Dodnor Creek and Dickson’s Copse Local Nature Reserve (LNR) is a wetland and woodland site on the outskirts of Newport. The site was once part of the ancient deer forest of Parkhurst but development and agriculture has left the area isolated from the main woodland block.
The site has been modified by industrial use since at least the 18th Century and contains a number of heritage features. It is also extremely highly designated for its habitat value – including as a Site of Special Scientific Interest and as a Ramsar Site. See our site listing page for information on how to get to the reserve.

Dodnor Creek is a dammed stream. Formally known as Werrar Marshes, the marshes are particularly valuable ecologically for the natural transition from fen vegetation through marginal scrub to ancient woodland.

Two land drains feed water from the surrounding area. Parkhurst Stream (also known as Swallow Gutter) enters the reserve at the south-western of the woodland from the prison complex at Parkhurst. Another unnamed stream flows through the north-western arm of the wood. Both are small but water flow is present throughout the year. The open water at the west of the site is brackish due to the inundation of water from the Medina at high tides. This is reflected in the vegetation seen.

The creek is used as a secondary high water roost by wintering birds including teal and little grebe. Approximately 65% of the SSSI unit supports reed swamp, particularly on the western side of the viaduct, dominated by common reed with some bulrush and willow scrub. Sea club-rush also occurs in localised abundance particularly east of the viaduct. These habitats are considered to be suitable for supporting the assemblage of non-breeding birds, particularly including dunlin, gadwall, little grebe, shoveler, teal and wigeon.

The woodland is recognised as Ancient Woodland in the Isle of Wight Ancient Woodland Inventory. It is well-structured and species-rich, dominated by pedunculate oak with ash on the higher ground with a rich shrub layer composed of holly, hawthorn, spindle, privet, butcher’s-broom, hazel and field maple, and a rich groundflora including much bramble and several ancient woodland indicator species such as lords-and-ladies, red campion, wood spurge, common figwort, stinking iris, primrose and violets.

Alder with tussock sedge dominate along the brooks. The site also supports several ferns, rushes and sedge including polypody, broad buckler and hart’s-tongue fern, soft rush and pedunculate and woodland sedges, along with a rich lichen and bryophyte flora. The woodland grades into reed swamp with willow scrub along its southern boundary. The woodland has chalara (ash dieback) present.

The woodland has a reasonable size pond which is dominated by white water lilies (Nymphaea alba), with emergents along the southern edge including gypsywort, water mint and bur-marigold. It is used unofficially by fishermen.

The woodland supports a variety of mammals including red squirrels (Scirius vulgaris) and the common dormouse (Muscardinus avellanarius). Shrews (Sorex spp), bank voles and wood mice (Clethrionomys glareolus and Apodemus sylvaticus) are also present as are rats (Rattus norvegicus), fox (Vulpes vulpes) and rabbits (Oryctolagus cuniculus). It supports a wide range of common bird species including the greater spotted and green woodpeckers (Dendrocopus major and Pica viridis), tree-creeper (Certhia familiaris), willow warbler (Phylloscopus trochilus), chiffchaff (Phylloscopus collybita) and blackcap (Sylvia atricailla). Barn owls (Tyto alba) breed on the eastern edge of the wood and grey heron (Ardea cinerea) have bred in the north-west arm of the copse.
