NWT Thorpe Marshes
Conditions good on main circuit. August
The nature reserve at Thorpe St Andrew Marshes – NWT Thorpe Marshes for short – was 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.
August: the season of high summer flowers, with pink and purple dominant. Though there are fewer flowers on the grazing marsh, though there are species such as marsh ragwort and square-stalked St Johnswort. Look in ditches for frogbit, orange balsam, fool's watercress and the poisonous lesser water parsnip. Plus butterflies, dragonflies and, with luck, wading birds on passage. It's also the best month to find the scarce red bartsia bee.

Top row: greater willowherb, meadowsweet, purple loosestrife.
Bottom row: marsh woundwort, frogbit in the ditches, rosebay willowherb.

Local history
These two blogs give an insight into Thorpe Marshes in the 1960s.
Thorpe Marshes in the 1960s (January 2018) and Thorpe Marshes in the 1960s part 2 (April 2018).
Former railway station: passenger trains ceased in September 1955 and freight in 1964, a local resident advises (22 Oct 2023).
Willow Emerald damselflies
Thorpe Marshes is a great place to see this damselfly in season (late July to October) and to discover more. Willow Emerald egg-laying scars are clear if you know where to look throughout the winter. A local discovery at Thorpe Marshes (January 2018) is Willow Emerald egg-laying scars on domestic apple - a first for the UK. More about this and other unusual places for scars here.

Wildlife habitats
The three key habitats at Thorpe St Andrew Marshes are the ditches, gravel pit and grazed 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.
Ditches
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.
Gulls over the gravel pit, December 2011
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.
Grazed marshes
Livestock are essential to manage the open grazed marshes habitat.
Without them, thick grasses and sedges would dominate even more, 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 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.
