Thorpe St Andrew Marshes

The willow tree that fell over the riverside footpath last week has been removed. Parking: the roadworks at the bottom end of Thunder Lane have finished (but the top end by the traffic lights is shut). Parking there and on Yarmouth Road is fine. 19 July

Thorpe St Andrew Marshes – NWT Thorpe marshes for short – is one of the Norfolk Wildlife Trust’s newest nature reserves, established in 2011. It's in the Norfolk Broads yet on the edge of Norwich in Thorpe St Andrew. It also happens to be my local patch – just down the road from home and the Honeyguide office, writes Chris Durdin.

NWT Thorpe Marshes is also within the area covered by James Emerson's Whitlingham Bird Report 2016.

July: bird song is petering out; occasional reed warblers and reed buntings may sing in the first half of July. It's a good month for dragonflies, damselflies and butterflies, when the weather's OK. Water soldiers & frogbit have white flowers in the ditches, and summer flowers like valerian and meadowsweet put on a show.

Wildlife habitats

The three key habitats at Thorpe St Andrew Marshes are the ditches, gravel pit and grazing marshes - see below.

Other habitats, which are all part of the rich mix, include:

  • rough marsh of willowherb and nettles, attracting many sedge warblers
  • sallow (pussy willow) scrub, good for Cetti's warbler
  • the adjacent tidal River Yare
  • adjacent wet woodland
  • areas of reed, including a reed rond on the river, attracting reed warblers.


Many ditches – also called dykes in Norfolk – have abundant water soldier and frogbit, both aquatic plants. These are indicators of good water quality.

In the Broads, the occurrence of the Norfolk hawker dragonfly, which is the symbol of the Broads Authority, is strongly linked to water soldier. The best place to see these is over the ditches close to the cattle corral.

Water rails and water voles use the ditches, though both are difficult to see.

Gravel pit

Gravel extraction – as at Whitlingham Country Park across the river – has led to the creation of a lake, which has filled naturally with river water. Some may call this a ‘broad’: the true broads are man-made, too, though from flooded peat diggings, and typically are much shallower.

The gravel pit here attracts wintering ducks, especially tufted ducks (picture below), pochards and gadwalls, moving between here and the Country Park. Unusual ducks call in at times, including smew, goldeneye, red-crested pochard and ferruginous duck over the 2011/12 winter.

Gravel beaches attract ‘loafing’ ducks and wading birds, which include little ringed plovers in spring/summer. Stock doves often feed on plant seeds on the gravel.

Grazing marshes

Livestock are essential to manage the open grazing marshes habitat.

cattle at Thorpe Marshes

Without them, thick grasses and sedges would soon dominate, and would in time be taken over by scrub.

More heavily grazed and trampled areas have a distinct structure of lumps and hollows that attract feeding snipe, and have flowers such as marsh marigold and lady’s smock.

the flood

The flood: the grazing marshes include a 'flood', periodically under water, then drying out, here with a greylag goose and mallards in March 2012. The bright green shoots are emerging yellow flag iris plants.
